Buried oil tanks rust (rust never sleeps) so oil tanks can leak.  

Do not be naïve that the tank that you are removing is rust free and has zero chance of leaking.  Anyone you hire to remove a tank should discuss the possibility of the tank leaking and what the steps would be to address a tank leak. In short, it should not be surprised that a buried metal object decades old may have leaked, so you should be aware of your options.  

In Pennsylvania what drives the need to remediate a heating oil tank discharge is if petroleum levels in the tank excavation are above the PADEP Statewide Health Standards relative to number two heating oil in soil.     The standards are as follows:

• Benzene:– (PADEP Standard is 0.5 ppm)
• Ethylbenzene: (PADEP Standard is 70 ppm)
• Isopropylbenzene (Cumene) : (PADEP Standard is 600 ppm)
• MTBE: (PADEP Standard is 2 ppm)
• Naphthalene: (PADEP Standard is 25 ppm)
• Toluene: (PADEP Standard is 100 ppm)
• 1,2,4- Trimethylbenzene: (PADEP Standard is 8.4 ppm)
• 1,3,5- Trimethylbenzene: (PADEP Standard is 74 ppm)

*Exceedance of any of the eight compounds indicates petroleum levels are above PADEP residential soil standards.  Please note that the most representative soil sample is one obtained below the tank which is only possible when the tank is being removed, or if the tank is being closed in place coupons or holes can be cut into the tank to obtain samples.. 

On the day of tank removal no one can tell you with 100% certainty that if they see holes in the tank that you need remediation.  You see without lab testing you don't know 100%.  If you are pushed to remediate right after a tank is removed, DON'T.   There are no savings and you risk spending money you may not have to spend.   We see firs recommending you jump into remediation if your tan leaks because they already have equipment on site, this approach is sure to lower your bank account balance with no guarantee of solving any problem.

So to understand oil in soil from a tank leak, you can compare it to cholesterol levels.   There are low levels of cholesterol (healthy levels,  that require you to take medicine or change your diet or life style) and there are high levels of cholesterol (you need to change your diet, possibly take medicine), in short high levels require corrective (remedial) action.  

You have to base any driver (need) to remediate a tank leak on laboratory analysis, which is obtained from sampling the soil after tank removal and which takes about a week to be analyzed by an independent laboratory.   So you sit in limbo for about a week to know where you stand.  Very similar to a Dr. visit with lab work.

Fact, many tanks, do not leak, many do, but not evert tank that leaks needs remediation.

Utilizing foam to fill an Underground Storage Tank (UST) can be a cost-effective approach to closing a UST.   Injecting foam into a tank can save the cost of excavating the entire tank.  Larger tanks and tanks that have access issues & hard surface coverings such as asphalt, building, paving or structures tend to be the ideal sites for foam filling.

Is foam filling appropriate and cost-effective for every tank?

The short answer is it’s not cost-effective in every situation.  People think you can just stick a hose into the tank and pump foam, but that's not the case. The tank must be exposed, entered, and cleaned of all oil before foam can be injected. Also, residual oil in the tank breaks down the foam, so the tank must be thoroughly cleaned of oil or else you will have an issue making proper foam.  In short, you have to enter and clean the tank, and for small tanks, it might take that much more effort to remove the tank, since you already excavated part of the tank to enter and clean it.

No matter if you foam fill a tank, fill a tank with sand/slurry, or remove the tank, there is still a set of tasks and associated costs that will be incurred, no matter the approach.

First, permits are required so the work can be inspected by the local municipality.

Second, the tank has to be excavated to some extent so the tank can be opened, entered, and cleaned. You see, you have to clean the tank of all liquid prior to filling it or removing it. Cleaning entails going inside the tank. Now depending on the size of the tank, the physical act of exposing the top of the tank may entail exposing 60% to 80% of the tank, which at this point, it may just be another 10 to 15 minutes to uncover the rest of the tank, making removal not that much effort.

Third, once the tank is cleaned, you need to test the soil, which entails cutting holes in the bottom of the tank. This takes longer than someone would expect, as the person who cleaned the tank has to leave the tank, change work clothing, to cut these holes. Whereas in the situation when you remove the tank, it is much easier to sample the excavation as the soil is exposed.

Finally, you have the task of backing the area. If you remove the tank, backfilling is fairly straightforward, as you have an open area to fill in.

If you are leaving the tank in place, you are tasked with placing material in the access hole you cut in the tank and pushing it to the far end of the tank. Remember the tank is a cylinder, and you need to fill the cylinder, and sand is not self-leveling.

Utilizing foam is convenient as it is self-leveling, but you also have to make the foam on-site.

The prep for making foam can be 1.5 to 2 hours. It’s kind of like baking, you need the ingredients, a proper mixture, and a temperature. You also have about 2 hours to clean the foam trailer post filling, as the equipment and lines have to be devoid of the foam ingredients or else they will harden and clog hoses, fitting valves, etc., so you are cleaning the kitchen, so to speak. Foam filling hits a sweet spot when you have hard issues accessing the tank with other materials, such as sand or concrete. Also, larger tanks (tanks greater than 2000 gallons) are more cost-effective to foam fill, as you realize the advantages of the foam cost structure versus the labor of using sand or slurry.

Propane tanks are uniquely suited for foam filling as they are pressure vessels and longer than the same size oil tank.  Longer tanks disturb a larger footprint to remove, so foam filling is an ideal solution for propane tanks.

Green Lawn Tips

During this trying time, you may be at your home more than you have been in the past.  As we try to find things to do where we are not around many people, it may be a good time to fine tune your lawn.

Americans spend over $6.4 Billion a year on lawn care, according to the Professional Lawn Care Association of America. While we are at home now, it may be a good time  now to ensure a beautiful green and healthy lawn.

Start out by checking the soil pH levels. Winter can alter the soil pH and create conditions that are friendly to weeds and disease. The soils pH should read between 6.5 and 7.0 which are slightly acidic. You can test your soils pH by purchasing a pH tester.    Lime can be added to adjust pH.

After the soil has been checked, invest in a rental aerator (you can group rent with a neighbor). In high traffic grass areas becomes compacted. The aerator will draw wine cork-sized plugs out of the lawn surface giving roots the room to spread and allow for air, nutrients and moisture to penetrate the soil.  Leave the cores where they lie a they will ad nutrients to the soil.

Pro Tip

The soil cores should not be raked, as they contain bacteria and nutrients that will return to the soil.

In the early spring, apply a pre-emergent weed control to prevent crabgrass in early spring. https://amzn.to/3b6dzXz (Right now would be a good time)

Pro Tip

½ the dosage of preemergent (now) and reapply in 3 weeks to increase the treatment duration. Try to get your immediate neighbors to do the same so you encompass a larger spread of weed control. If your neighbor does not apply preemergent, weeds can grow and move to your yard.

During late spring fix any patchy places and apply your seed. When seeding in the spring it is pertinent that you provide consistent watering to allow the seed to germinate

Pro Tip

When you plant seed, the seeds must reman wet to germinate. Water twice a day for 7 to 10 days to allow the seed to germinate.

When watering, make sure one inch of water to 12 inches of soil is preferred ratio for watering actively growing grass. You most likely will have to seed again in the fall months.

Pro Tip on conserving water

Twice a year in season (Spring and again in July) apply a wetting agent, this makes water wetter.  Wetting agents apply a non ionic surfactant (soap) which allows water to more evenly penetrate soil (think less run off).  Golf course follow this process. Lawn Wetting Agent

With the spring upon us, it is very important to prepare your lawn for the warmer, sunnier months ahead. Having a nice, thick green lawn helps with excess rain, capturing the moisture so it does not end up in your house to produce mold.

Questions about Mold growth?

Crazy times, first full day of Spring and we all want to be sprung, but realty is more likely we will be staying at our homes for awhile.

If you like to be in your yard AND you have had issues with mosquitoes in the past, maybe this is the year to seek professional help by having mosquito control & remediation performed in your yard. Our service will remediate (remove) mosquitoes from your yard.

Book a seasonal service, 8 applications and get $25.00 off. We start treating mid to late April.

Why start controlling mosquitoes in early Spring?

You start early whack the buggers, then you keep them suppressed for the rest of the season with reapplications every 3 weeks. It more effective the earlier you start because:

1. We treat foliage as mosquitoes need the nectar from the leaves for food (blood is just for laying eggs and only the female bites).

2. With minimal foliage in the Spring, statistically speaking the mosquitoes are likely to encounter our barrier spray SOONER rather than later.

3. Treat early BEFORE you have a problem. An ounce of Prevention is worth a POUND of cure.

Many planned developments used heating oil.  In developments where the condominiums are housing, the homeowner does not own the land where the oil tank is located. In condominium housing developments most heating oil tanks are usually placed on common ground.    So you have a situation where you must remove the tank from property. The condominium owner does not own the heating oil tank. Homeowner associations, as anyone who has dealt with one, have many restrictions on what you can and can't do, they also make you jump through hoops to remove oil tanks.  These restrictions, while meant to maintain order and assure that work is performed professionally, also add to the oil tank removal cost.  We call these project "White Glove Tank Removals", as they require the white glove treatment.

Curren recently completed a project and  from the photos below, it is hard to differentiate the before and after photos. Hence the white glove treatment. 

The tank is in the planting bed between the dwelling and the sidewalk.  Planning ahead, allowed the parking spots in front of the tank to be clear to allow access.

The blue line is an old landscape sprinkler line.

Next you hand excavate to clear PRIVATE utilities.  Most all homeowner's associations have no clear idea regarding what utilities are where, so you hand dig to clear the excavation.

You dig until the top of the tank is exposed.

This tank was previously filled in place with sand. 

To remove the previously installed sand, you have to cut the top of the tank off so the soil can be scooped out.

Soils were removed and placed into a dump truck that removed the soils from the site.  This tank was in New Jersey and New Jersey doesn't allow you to back fill with soils removed from an oil tank.

This is the after removal photo.

Tank removed and back filled, almost like we were never there.

Over 20 years of experience and thousands and thousands of tanks removed, when you engage Curren Environmental you get our experience and expertise.  This may be your first and only tank removal, for us it's just what we do.  If you want your project completed professionally, call Curren.

"Why do I have mold?", is a common question we get from people who discover mold in their homes.   The short answer is that 95% of the time it is a moisture or a water problem.   Yes, mold can come back after remediation if you do not fix what caused the mold.  It can also come back if the mold was not properly remediated (wiping with bleach is not mold remediation).

Thousands of mold inspections and remediations have allowed a broad evaluation of mold growth patterns.  You can't be a good mold inspector if you are not accomplished in mold remediation.  Getting down and dirty remediating mold allows you to witness first hand how mold growth has occurred.  Remediating often times requires you to open up walls to get at the mold growth and you obtain a perspective as to how/why mold grows. 

For instance, wood studs allow mold to grow more aggressively than metal studs when you have a wet area.   Floating concrete slabs can enhance mold growth on ceilings. When there are areas of termite damage you should expect to find mold growth as termites like a moist environment, like mold.   Did you know that your beloved mulch beds around your home can aid in humidity in a basement and crawlspace? Thus, creating an ideal environment for mold growth.  Also, the dehumidifier bucket that you got sick of emptying (filled with water every 2 days) now sits unplugged in the basement, ruining your line of defense in controlling moisture and keeping mold at bay. These factors as well as a host of other environmental and degrading building in fracture are the common culprits that cause mold to grow in a home.

(For example, lack of drainage and added mulch beds led to mold growth)

Curren Environmental does mold remediation to homes that have had mold remediation previously and the mold grew back, meaning remediation was not successful.  This happens due to top lack of following proper mold remediation protocols, using inferiors products to prevent mold growth from reoccurring and lastly removing the moisture source (many times there are more than one source) identification.  (Curren had one project where there for four sources of moisture that fueled the mold growth.)

Mold growth is typically found in homes when the property is being sold.  It may not be bothering the seller, but it may affect the buyer.  Everyone has different intolerance and tolerances to mold growth, one of the reasons there are no federal regulations governing mold growth. Mold growth can be a huge real estate deal breaker. If it wasn't it would be on the sale sheet, showing the moisture or water issue and where the area of mold growth. 

No, mold growth will not be on the sale sheet.  It is best to remediate the mold growth before the property is on the market, removing the issue in its entirety.

You recently had your oil tank removed and there were holes in the tank. However, there are no indications of soil contamination but the company that removed the oil tank filed a report to the New Jersey Department of Environmental Protection (NJDEP). You are unaware that you may have been naïve in choosing your oil tank removal company due to the fact that removing an oil tank hopefully would be a once in a lifetime event. At this point, you understand that clearly your tank removal contract should have included soil sampling, but it did not. You are also unaware that soil sampling must be completed, then the report is sent to NJDEP to close out the case number (assuming that it meets the state parameters for acceptable oil levels) and rescind the remedial action. 

Regarding what soil sampling is and how it is performed, there are permissible levels of oil that can remain in the ground and conversely there are levels that would require remediation. New Jersey regulations require that upon removal of an oil tank that has evidence of a leak, you are to obtain a minimum of 5 soil samples from the tank excavation (5 for a 500 gallon tank and 6 for a 1000 gallon tank). This is relative to your contract for tank removal. If the contract did not reference soil sampling, you can’t guarantee soil samples would be obtained. Soil samples are critical to assess the tank excavation for petroleum levels. The testing is meant to inform the property owner if indeed oil levels are present and remediation is warranted or that levels are within permissible limits and can be left in place. Now, you, as the owner of the oil tank that leaks can make an informed decision regarding remediation. 

If your tank removal contract does not include costs for soil sampling or discusses the possibility of finding a tank leak, it is pretty safe to assume that the tank removal company is looking to find a leaking tank and remediation.

In a situation where a tank is removed, found to be leaking and no soil sampling was performed, you should be concerned as to whether the soil needs remediation. All discharges are required to be reported to the NJDEP (If your tank contract doesn’t inform you that a tank leak is reportable, think again about who you are hiring).

Example of soil testing by soil borings. 

The only way you would know if your tank leak has petroleum contamination in the soil above or below NJDEP permissible limits is to have soil sampling performed. If all your samples are in compliance with NJDEP regulations you will receive a No Further Action (NFA) letter that will close out the NJDEP case number. This can be performed without having to perform actual remediation, which is typically soil removal.

Again, the tank removal contract should have addressed obtaining soil samples and what to do if a leak was noted. Remember, holes are never good in an oil tank and you rarely will see physical evidence of an oil discharge in a tank excavation, meaning you are not going to see oil or stained soils.

What you should know about removing an oil tank.

Since the northeast part of the United States was part of the original Thirteen American Colonies  we have a longer history of oil heat than other parts of the country.  You can find oil heat in homes that were built before the mid 1980's going to 1900.  If you have a house circa 1800's or the early 1900's there is almost 100% certainty that oil heat was utilized at some point. Heating oil was stored in either aboveground storage tanks (ASTs) or underground storage tanks (USTs) for heating homes, and other commercial applications. Nearly 100% of oil tanks were constructed with steel, fiberglass wasn't even considered for commercial use until the 1970's and even then commercial use was limited and residential was near nonexistent. Rust never sleeps and all steel will corrode over time, buried tanks will corrode faster than aboveground tanks, thinner tanks faster than thicker tanks. The reduction of sulfur from heating oil to help with clean air actually increases biological activity in a tank and this bacteria can crease corrosive byproducts which can actually corrode a tank from the inside. 

It has been estimated that almost 100% of the buried oil tanks have exceeded their reasonable life span and should be replaced.  (The average warranty on a new tank is 20 years, a great roof has 40 year shingles, so you do the math). How long does an oil tank last?  The number for ASTs nearing retirement is closer to 50% as many of the AST are newer, having replaced older USTs.  Oil tanks are rarely ever replaced and almost never with another UST.  If a UST was replaced with an AST it was probably because there were issues with the UST taking on water or losing product.  To put tank age in perspective:

Home Built in 1980 = 39 year old tank

Home Built in 1970 = 49 year old tank

Home Built in 1960 = 59 year old tank

Home Built in 1950 = 69 year old tank

Compare tank life span to common wear and tear items:

Roof shingles last 20 to 40 years

Hot water heater 20 years on average

What you should know about removing an oil tank is that there is a possibility that the tank leaked and any buyer of the property  will want testing performed at time of removal to document that the tank didn't leak.  In short, do not buy a property that had an underground oil tank removed without a report documenting the removal and associated soil testing.

Common questions we get asked about buying a home with an oil tank:

Would I buy a house that:

Had oil tank removed with no soil testing or report, no.

Tank removed, owner has a page of lab day, no report, no.

Tank was filled in place with sand, no soil testing, no.

House has an in use underground oil tank, no 

If you want to know why no was the answer to each question, call our office and speak to a professional  856-858-9509.

For a property owner removing an oil tank, when they speak to firms concerning oil tank removal the possibilities of a leak and necessary soil testing should be discussed and put in writing as leaking tanks can spiral projects costs into the tens of thousands of dollars.  I say this as we get calls from people who had a tank removed and they feel a bait and switch occurred.  They never discussed the tank leaking, hired the cheapest company and after removal the company pointed out the smallest hole in the tank to owner and construction inspector to ensure they tank fails inspection.  What followed next was a $10,000.00 estimate for remediation, that's when our office gets called.

What you should know about removing an oil tank is it is a very complicated process, in particular in New Jersey.  In August of 2018 NJDEP revised regulations requiring 5 soil samples to be obtained from an oil tank that is removed and evidence of a leak is noted.  NJDEP Oil Tank Regulations August 2019  Our office has yet to see any tank removal proposal since August that references these new regulations and the required soil testing.  I know this as we get THE CALL from unhappy tank removal clients and the contracts they signed for tank removal are vague and ignore the steps you have to take if the tank leaks.

Why do NJDEP regulations require you to take five soil samples when a tank leaks?  The soil samples are meant to thoroughly evaluate the tank excavation for oil levels. You see rather than assume the tank leak requires remediation, the NJDEP wants you to test each sidewall and the bottom of the excavation, this allows you to make an informed decision as there are a couple possible outcomes from an oil tank leak, here are a few:

1. Oil tank leaks you acquire the five post removal soil samples all samples have oil but nothing above permissible limits.  No remediation, financial disaster avoided, although you do have to pay for the testing, NJDEP report and the $400.00 review fee.
2. Of the five soil samples acquired one is above permissible limits.  This is good and bad news.  Bad news you have to remediate, good news you know WHERE you have to remediate.
3. Tank leaks and you take no soil samples.  You assume all good as you have no testing data saying you exceed; tank firm assumes all bad and remediation required since they have no testing data saying all good.  The rub here is you the tank removal client is not supposed to know all the ins and outs of the regulations, which were not discussed with you prior o removal.  Even if your oil tank has a 1% of leaking, is it not important the scenario of  a tank leak be explained in writing to you?  If the answer is no, don't read any further.

Curren Environmental has been performing tank removal for over 20 years, in New Jersey, Pennsylvania and Delaware.  Our office will take the time to discuss your project answering all you questions and discussing the good and the bad.  A common statement we tell clients is we tell you what you don't want to hear, meaning we discuss the downsides meaning the leaking tank situations so you are at the least aware of the possibilities. When you receive a written scope of work from Curren what was discussed is in writing including soil sampling cost and NJDEP reporting if required. If you want a professional opinion, a professional tank removal and most important a professional report documenting the tank removal, call our office.

How to remove an oil tank.

The northeast United States has a long history of oil heat. Oil tanks were commonly used starting in the early 1900s until the 1980s The EPA was not formed until 1970, so oil tanks and environmental regulations did not grow up together.  Today the liability of oil tank leaks is well known and both buyers and sellers

The concern regarding an oil tank is any tank has a chance to leak. If a tank leaks, there can be a cleanup expense involved. This expense falls upon the owner of the property at the time of discovery. Try selling a house with an oil tank and learn that the buyers want a home not an oil tank leak. The fact is a new tank today has a 10-year warranty (yes there are tanks with longer warranties, but those are quite expensive), so nearly all tanks in use today have reached what would be considered a reasonable life expectancy. Couple that with the fact that if your tank is leaking, it most commonly happens along the very bottom of the tank where the most corrosion occurs, so you would never actually detect that the tank is leaking. Quite frankly, no tank owner is going to miss drips of oil from a tank.

So, you have an old tank, a house you want to sell and a dilemma, do you remove the tank like a proactive reasonable person would do, or do you stick your feet in the sand and sell the house as is? Well rest assured your buyer has read this web site, or their attorney, or realtor has and they know the issues with oil tanks. We find a sale has to fall through 3 times or the house has to be on the market for 6 months or more before the seller accepts the fact that an oil tank is not as appealing as walk in closets and an open floor plan, buyers will take a hard pass.

So now the tank owner is looking to have the tank removed. A little internet search or a reference from someone leads them to a company happy to remove the tank. Cheapest price, absolutely that is what they want. Does the removal company even discuss the possible outcomes of the tank leaking? No they don't, they don't want to scare you and quite frankly you don't want to be scared, you're a tank expert, you know your tank isn't leaking and hey oil comes from the ground and you're pretty good about recycling so you're a green person.

Let me point out some pitfalls about removing your oil tank.

The cheapest price includes the worst service and you will wind up paying more in the end, 90% of the time. The cheap person wants to find a leaking tank because that is where the big costs are. Read the tank contract, it will be brief, but it needs to include the following and most will not.  We know this as we get many phone calls from people complaining about the firm that removed their oil tank.

Soil Sampling

You think you do not want it, but the buyer wants to know if the tank leaked how you know 100% is via soil testing. Like cholesterol, you do not know the levels unless you test.

You should always include sample acquisition and analysis with a tank removal. Samples on average cost $120.00 each or $240.00 on most tank removal sites. This is cheaper to do when you are on site to remove the tank. If you have to go back to the site and drill to obtain soil samples expect it to cost thousands. Sampling is even more important when a tank sweep is performed and a tank is found on a site, meaning, a tank that was not in use and not known to exist.

Hole found in the tank

Let us agree that things are not made to last forever, things wear out, is it really a shock to remove an oil tank that is 20, 30, 40, 50 years old and find a hole in it. I mean is that out of the realm of possibility? If you were not informed of this possibility, be prepared to be taken advantage of, tank leaks, not all of them but some. To manage expectations the company that removes your tank should explain what will happen if your tank does or does not leak. To be clear if there are holes in the tank, the local construction office will flag the tank as leaking and have you report the leak to the state. The reason being a hole in a tank is reasonable cause to believe that the tank leaked. So now, you are tasked with proving it did not leak or does not need remediation. In the meantime, the tank removal company will be giving you a quote that is many times more expensive to remediate the leak.

The tank had holes and you are told you must remediate.

If a tank leak is found you MUST test to see if levels are above or below standard.  If you do not test than it is going to be assumed you must remediate, prepare to open your checkbook.

If you have a tank leak and you test and oil levels are so high that you need to remediate then your next real step is to define the area requiring remediation, this is called delineation.

Delineation is meant to define the area of contamination (and verify that contamination exists). Smaller areas are faster and less expensive to define, larger areas take longer. Larger areas can extend across property boundaries and below structures, which can require overcoming access issues regarding sampling these areas. The first step which maybe the only step required is sampling immediately around the tank area.

Tank Closure Report

Did you know that commercial tanks all require a report to be submitted to the state to document the work? Why, the state wants to know if the tank leaked. Therefore, every company is used to completing reports of tank removal work. Clearly, any tank raises questions with owners/purchasers of a property, so why wouldn't you want a report of removal? You do and you should have a report, when contract. These reports explain the work in laymans terms regarding the tank work and if there was a leak, it will also outline why you do or do not need remediation. Having a report documenting that a removed tank did not leak is an important document to have.

Bottom line, every tank needs a report documenting removal. Be it a leaking tank or a non leaker, if your contract makes no reference to any report,  I wouldn't sign it.

Curren has completed thousands of tanks, one month we completed closure on 129 tanks. That said, we do not remove every tank in the tri-state area, but we get calls from property owners who hired someone else to remove their tank and they feel like they are being treated unfairly. Meaning they were unprepared to find that the tank leaked. In practice, I don't expect a property owner who has never removed an oil tank and never will again to be all knowing about the tank removals and tank leaks, but I expect the company performing the work to know and to clearly explain the process and the scenarios you can encounter.

The follow exert is from a tank removal contact from a company I would have run away from. Give it a quick read:

• Obtain necessary permit from municipality
• Phone in utility mark out to NJ One Call
• Excavate to expose tank
• Remove overburden soil covering UST
• Remove and dispose of concrete adjacent to UST.
• Saw cut the UST to allow for hand cleaning
• Properly clean the UST interior
• Remove the UST, and dispose of at a properly facility

This scope assumes the tank is not leaking. Bottom line the scope they gave was not meant to really satisfy you if the tank leaked, which was clearly a possibility. They don't even include soil sampling or a report so if the tank doesn't leak you don't get a report saying so. If the tank did leak, no sampling is include, which is so wrong, you need to test as every state allows a permissible amount of oil to remain, like cholesterol there are good and bad levels.  How else do you know if you need to remediate?

We can only hope you are reading this before you get your tank removed. If so, call our office you will walk away a lot more informed and better prepared to manage this project. If you are calling after your tank was removed and it leaked, call us, we can discuss your options. Most leaking tanks will require the contamination to be delineated, which we do. We can define your problem, develop costs to remediate as well as data to you that you can solicit other quotes for remediation.

If you are involved with an oil tank removal project, it is probable your first tank removal and likely your last. The odds of you making the best decision are slim. Let’s agree that the best tank removal is one where the tank does not leak and you don’t have to remediate.

That said, you could expect a cost for tank removal on average to be about $1,500.00. This cost entails the time to get permits, equipment and labor to excavate the tank, trained personnel to cut open and clean the tank, oil recovery, tank removal, soil sampling, backfill material and labor and ultimately a report from the company so you can document the tank removal. The tank report is completed weeks after removal and is performed in an office utilizing the notes and data collected from your site. Sounds like a lot for $1,500.00, well it is.

Let’s talk about what makes your tank removal the best tank removal.

Your cost is close to the average cost of $1,500.00. Why, well the firm that sells these services has to do the work at a market rate where they can make money. Otherwise, they are offering the work at a loss, with the plan that they will make the money on the backend, which is the remediation and even a small remediation can cost over $5,000.00. You get what you pay for, remember that.

If you buy a house that had an oil tank, you want to know that the tank did not leak. The only way to know that is if you have testing completed. Being the owner of the tank you may think you do not want to have testing done, or else you may find a problem. After 25 years of dealing with tanks the bottom line question everyone wants to know is if the tank leaked. Buyers and sellers because that answers can make or break a real estate transaction. Bottom line tank soil samples when the tank is removed

Why do many contracts for tank removal not include soil sampling? Short answer, it is cheaper. Soil samples cost $120.00 on average and with two soil samples being the average number acquired sampling can raise the cost by $240.00, plus the time to write a report that talks about the test results. Look, you are removing an old buried metal object, you are fooling yourself if you don’t think that rust and extensively has not occurred to the tank. Your low cost tank removal company is counting on this and will be happy to give you a cost to remediate the tank once contamination is discovered.

Why do many contracts not include a report of the tank removal? Cost again is the culprit. If you write a report you need someone present during tank removal that will be taking notes, photos, soil samples and will eventually sit behind a desk to type a report. That all takes time and there is a cost involved. Bottom line make sure the contract includes a report.

Tank removal site assessment soil samples when acquired for independent laboratory analysis provides quantitative not qualitative data. New Jersey and Pennsylvania have one comparative standard for number two heating oil in soil and that is by laboratory analysis. Visual, oil water agitation or olfactory evaluations have no standards so you have no foundation to lay an opinion.

Residential tank removals do not specifically require that you obtain soil samples. This conflicts with the interest of a purchaser (mortgage or insurance underwriter) for a site when hard data is requested. Legally you do not need to test, if a buyer wants to test prior to purchase it is their due diligence and hence their cost. Obviously it is less expensive to acquire samples from an open excavation at tie of removal, as opposed to post removal and backfilling.

What is the best tank removal? The best is one where testing and a report is provided as part of the tank removal. It is what is required for commercial sites, so why wouldn’t you do the same for a residence?
