If you are purchasing a property with an abandoned oil tank, be concerned that you are playing with fire.  Let's be clear, the concern with any oil tank is if the tank leaks.  If the property with the abandoned oil tank has a report that includes soil testing you should not have any concerns,  but that is not the common situation when a property has an abandoned oil tank.

The real hurdle regarding a property with an abandoned oil tank is that the owner does not want to do anything with the oil tank.    People will say the tank is fine, that they, themselves, purchased the house with the abandoned tank so its fine for those homeowners because they don't have the monies to remove the tank. 

So what is the underlying issue? The homeowner doesn't want to find that the tank is leaking.  It's costly to remediate, and they can easily pass that along to buyers who don't do their due diligence.    In some cases, buyers are tempted to take a credit for tank removal to allow the sale to go through.

This photo is from a leaking oil tank.  Cleanup cost exceeded a $100,000.00

I cannot advise having the work performed after settlement as you do not have enough data to determine what would be a prudent amount of money to set aside in escrow in the event that the oil tank leaks. For your reference, a small oil leak can cost $5,000.00 to $10,000.00, with larger oil leaks costing tens of thousands of dollars. In the absence of a written narrative (report) from the tank closure company and associated laboratory analysis that would have been performed during the closure activities, you cannot say that the tank does not represent an environmental issue.

Oil tanks represent an unknown financial liability that can affect the value of a home, the ability to obtain a mortgage and homeowners insurance. Since the abandoned oil tank is the hurdle to overcome in a real estate transaction, removing the oil tank is the logical course of action.

An Abandoned tank, closed in place tank, decommissioned tank, can mean many different things.

Abandoned oil tank can mean:

Tank is abandoned, stopped using it and left it "as is".  Think of it as an abandoned car.

This oil tank was abandoned 11 years ago when they switched to natural gas.  About 75 gallons of oil was left in the tank or should I say abandoned.

Oil tanks abandoned in place means something was done to the tank, like filling the tank with sand, stone, concrete or foam.  The question is was the tank cleaned and sampled?   A report would help secure this situation and address concerns of a tank leak.  This situation commonly has no documentation regarding the tank leak, the reason being is the owner didn't want to find  a problem, so no test, no problem can be found.  This is legal, but leaves the unanswered question regarding a tank leak to be answered when the property is sold.

Tank abandoned in place with a permit and inspection by township, city or municipality.   This is the most dangerous of abandoned tanks as buyer and sellers assume that the permit and inspection portion of the work certifies the tank as non leaking.    This is actually not what the town inspects for they inspect for the physical work completed. 

Abandoned oil tank, no paperwork, current owner bought it with the abandoned oil tank.  Tank was abandoned from a prior owner and there were promises that it was done properly but you have no written documentation.

This tank was abandoned in place, we removed sand, slate pavers, bricks and beneath all that was oil. 

Tanks abandoned in place and the work was done by the homeowner with some friends. No permits, but a really good story about what hard work it was to do.  Yes - this does happen and 99% of the time the DIY tank abandonment is not performed as well as it could have been performed.   Think about it if you have never done something before how good are on your first attempt?

This tank was foam filled, but the tank was never entered and cleaned.  So oil remained in the tank.   You can see how the foam is discolored from the oil.

 

Tank abandoned in place, but the tank was actually best served to be filled in place due to obstructions.  Meaning there are tanks by pools, under decks, under garages, basically in a location where it would be excessively expensive, even dangerous to remove so the tank gets abandoned in place.  This is common on commercial tanks as commercial tanks are larger and longer and removal causes a larger footprint of disturbance.  In this circumstance after the tank is cleaned samples are acquired and a report documents that yes a steel object remains on the site, but it is technically no longer a tank as it can't hold  liquid (there is a big hole cut into the top of the tank).   This is what we do to document commercial tanks that are abandoned in place, you should expect the same for any residential tank.   Why an abandoned tank may not have a report is either the owner not wanting to test and find a problem, cost, owner went with the cheapest company (cheap means something is lacking) or simply the company that did the work doesn't test, or isn't licensed for testing. 

25 plus years of oil tank work, Curren Environmental can confidently say 99% of oil tanks can be removed.  So many abandoned tanks should have been removed but were not.   Don't buy a property with an abandoned tank that you are  not 100% certain it did not leak.

Mosquito remediation service treats your property for mosquitoes, but really is the definition of remediation? 

• Fix an underlying condition causing a problem.
• Removing something that is unwanted.

If you don't want to get bit by mosquitoes, you want your yard remediated, meaning the "removal" of mosquitoes.  Mosquitoes are a problem that Curren's will remediate.

We precisely treat mosquito breeding areas in your yard.  We target the mosquito life cycle including both adults as well as eggs.  The following photo highlights where you will find mosquitoes in the heat of the day, that is where we apply our treatment.

 

Our trained technicians will inspect your property for mosquito habitats (yes you have them too) and will take the appropriate treatment measures.    If we find issues on your property our software program will email a photo of that specific problem area on the day of treatment.

Our treatment has an immediate (24 hour) knockdown on the mosquito population in your yard.  A residual barrier portion of the mosquito treatment provides continued protection for 3 weeks.

This video shows a yard being treated, which includes landscaping and fences.  We don't treat where you sit and eat, since mosquitoes don't breed there during the heat of the day.

 

If you have a yard you want to enjoy then you should call and speak to one of our professionals.

 

                              Disinfect for Business Reopening

As the economy reopens, businesses are asking employees to return to work.  Safety of its employees are on every business's mind.   Many work spaces are undergoing a deep office disinfecting prior to employees returning to their place of work.  This professional disinfecting reboots the space.

 

Office Disinfecting

Curren can apply an EPA N listed disinfectant to treat areas where your employees work.  Utilizing precision application equipment, including cold mist foggers, which have power-mist capable of 56 micron droplets to ULV 20-35 micron droplets to surfaces throughout the space. These powered devices can yield single digit micron droplets: or deliver a soaking mist dependent on the surface treated. As indicated by the name, ULV (Ultra-Low Volume) misters and foggers transform low amounts of fogging liquid to substantial yet very fine droplet mists ensuring thorough application to surfaces.  This ensures that surfaces  are thoroughly treated

   

Disinfectant Efficiency

Curren has been using disinfectants for years in our mold remediation projects.  Our disinfectants are commonly used in hospitals, hence the appeal of using them on our project sites. The U.S. Environmental Protection Agency (EPA) produced and maintains a list of EPA-registered disinfectant products that have qualified for use against SARS-CoV-2, the novel coronavirus that causes COVID-19. Fiberlock Shockwave Concentrate with EPA registration 61178-73884 is on the list and will be utilized for this project. (List N).  Shockwave is Curren's choice for mold projects and for disinfecting business office spaces. 

While surface disinfectant products on List N have not been tested specifically against SARS-CoV-2, the cause of COVID-19, EPA expects them to kill the virus because they:

• Demonstrate efficacy (e.g. effectiveness) against a harder-to-kill virus; or
• Demonstrate efficacy against another type of human coronavirus similar to SARS-CoV-2.

Curren's technicians are trained in PPE (personal protective equipment) procedures such as how to put on and remove PPE equipment and utilize proper PPE during the duration of all work activities.

Professional office disinfecting allows businesses and landlords to help ensure the safety of their employees and provide the space a safe environment for business operations.

The CDC has many guidelines that businesses should follow once operations restart.  Once you reboot a space you have to follow your own plan such as:

1. Limit entry of the work space to employees only. You must then trust your coworkers to be safe. FedEx, UPS,  food delivery everything gets stopped at door.
2. Disinfecting common areas, such as copiers, during the day.
3. Provide hand sanitizers in office for employees use.
4. Offering masks and gloves for employees to use.
5. Installing plexiglass at offices on desks in common areas.
6. Keeping doors open so door knobs (common touch area) don't get touched.

CDC Guidance can be found here: CDC Guidance Documents.

 

 

 

                                          Mosquitoes and Mosquito Control
Mosquitoes are both a nuisance and a health threat. If you do not want to be bitten by mosquitoes in your backyard, you must reduce the mosquito population.

• 
  All mosquitoes need water to breed and survive. DIY Mosquito Control can be performed by eliminating breeding sources such as the following:
  • stagnant water
  • water trapped on tarps
  • old tires
  • tree pots
  • puddles
  • clogged gutters
  • buckets and flower pots
  
  

 

 

 

 

 

 

 

 

Mosquito Remediation can help eliminate the nuisance of mosquitoes and protect your family. Our professional applicators will walk around your home and throughout your backyard to address your specific problem. We are trained to identify the unique areas of risk around your property. Adult mosquitoes are found resting in vegetation or other cool shaded places (under decks, sheds) during the day time. To get rid of adult mosquitoes we spray the lower portion of foliage, bushes, tall ornamental grasses and shrubs with a microencapsulated ultra low volume , insecticide that will prove an immediate knockdown of mosquitoes and with micro encapsulated technology provide a 21 day residual. Our barrier application as we call it (this shields you from mosquitoes) is safe and effective as we only treat areas mosquitoes are likely to feed and reproduce as well as hide from the heat of the day. We often call under decks and sheds mosquito condos.

Enjoy your yard without mosquitoes.
We recommend a treatment every 21 days to ensure effectiveness. Our dedicated software will remind you in advance of your next application, provide electronic notification the moment it is completed and if we find problem areas in your yard you will receive photos via email or text of the concern. Once you sign up you can literally sit back and enjoy your yard. Our schedule is automatic, no one needs to be home. We only ask to allow 30 minutes post treatment for the barrier to fully dry before returning to the yard.

Mold likes to grow where people don't like to be.  Attics are a common place where we find mold during inspections.  Home sellers are often surprised to find out that they have mold in their attic.   Attics are not heated nor air conditioned, which means both humidity levels and temperature fluctuations are very varied and due to these conditions mold will find a home to grow.

All photos you will see on this page are from the same attic, each area of mold grew because of different environmental variables.

The mold you see in this photo was caused by the bathroom vent leaking moist air onto the wood sheeting.

 

The mold in this photo was from natural humidity over the years.

How do you correct attic mold.  First you need to identify the moisture source and correct the issue.  Attic mold may be caused by insufficient ventilation or air leaks from finished spaces.  Some bathrooms will vent moist air into the space creating an environment for mold growth.

 

Remediating mold rarely ever requires replacement of the wood surface but rather thorough cleaning of the wood, application of a fungicide and lastly a preventive coating that warranties that the wood will not allow mold growth.

 

This photo shows an attic that has been remediated.  The white coating you see is fungistatic, meaning it inhibits mold growth.  These coating provide the owner a warranty that mold will not grow on the treated surface.

 

Curren environmental has over 20 years experience with mold, we have remediated thousands of properties over the years.

If you have a mold question or requested mold remediation Curren can help with an appropriate solution.

 

 

 

 

Mold remediation is the process where you remove the mold as well as the source of the mold growth. The most important part of any mold remediation is knowing what caused the mold, since mold can come back if the driver of the mold is not stopped.

 

You can complete mold inspections with infra red cameras (photo above), that are calibrated for moisture.  This inspection tools can help you pinpoint problem areas behind walls and other materials. 

Since "mold = water", the source of the mold should be determined and repaired (water issue). It is possible that the cause of the mold was repaired, but if it was not, then the necessary corrective action is needed. A qualified mold remediation company should be able to ascertain the cause. If they cannot, you are dealing with the wrong mold company. Remember only 11 states have mold regulations, so you are likely dealing with an unlicensed company.
 Tough to see in this photo, but if you look through the plastic you see mold.  where as you do not see mold on the white ceiling or the concrete block wall above the plastic.  This mold growth was driven by improper vapor barrier installation.  100% preventable.

For successful mold remediation, you must remove the mold from impacted surfaces. (Mold remediation can entail deconstruction of walls to get access to the mold). Mold removal is typically accomplished via HEPA vacuuming surfaces. If items can not be cleaned than  demolition of items such as sheetrock and/or wood framing that is water damaged or mold impacted on both sides is necessary.

Application of a broad spectrum fungicide is another step. Fungicide application sterilizes the space, disinfecting the surfaces to address any mold spores that can’t be seen. It also allows porous surfaces to absorb the fungicide, grabbing spores that may have implanted themselves deeper into the surface of the material. This is common of wood surfaces as wood is porous, ensuring that you are rebooting the space.

The final and most important step is applying a fungistatic coating to cleaned organic surfaces in the area of remediation. This coating essentially provides mold proofing in the treated area. The best coatings have 10 year warranties. The coating is not a paint you buy at a home improvement center, but a coating that is designed for a specific purpose which is mold prevention. Coatings with fungistatic agents are commonly applied to new construction to mold proof the space. The application of fungistatic coatings as part of the remediation is also a corrective action that is designed to help the space resist mold in the future.

Mold is a four letter work and most companies say they know mold and in reality they  don't. Mold experts for over 20 years, billions of spores remediated.

You can smell mold?

Spending more time at home than usual? Many people are in the safety of their homes and our office is getting called regarding musty smells, that people think relates to mold in their home. These calls coincide with rain events and we find a simple equation. People have mold in their homes they didn’t know existed. Many people find mold during a real estate transaction, since that is when a home under goes scrutiny, meaning multiple inspections occur and the wear and tear items that we often ignore are brought to light. I mean do you ever go into your attic or basement and look for mold?

The musty smell you have is most likely mold and it is active mold growth because when mold is consuming organic matter it off gases, hence the smell. Growth can correlate to rain events (not necessarily flooding), temperature changes, and humidity levels. In short moisture above 55% humidity as most molds in the northeastern United states will grow above that range.  Add in the fact that the northeast has an older housing stock and you have a higher probability of mold. Why older homes have mold, simple put the older a home the greater the time frame for mold to grow somewhere in the home. This gives mold the toe hold it needs as mold won’t die when it is dry it just goes dormant. This mold will then grow sporadically (no spore joke intended) over time until the owner complains of a smell, has a health concern or buyer’s inspector finds mold

 

Our calls lately have been from people who are working from home or simple spending more time at home and they either smell musty odors or are having health concerns. These people never had a mold inspection performed so the idea of a mold inspection makes sense.  Our mold inspections typically find mold, which makes sense.  The key to finding mold is understanding why it is there and how the mold can be addressed (mold remediation) and future prevention.  A typical mold survey might find a half dozen reasons why it’s there (yes there is typically more than  one cause for mold growth. We provide the homeowner a DIY  list for everything they are doing wrong and a corrective action plan (mold remediation) outline and costs. All mold remediation has a 10 year warranty against future mold growth, best in the industry.

We also teach several classes on mold so you know you are getting expert advice.

 

All our inspector use N-95 masks and have at least five years experience with both mold inspections and remediation.  We inspect and remediate mold so we get to see mold from both sides which gives Curren a full perspective.  Different building materials from pour concrete walls, to cider block walls to wood studs to plaster wall all affect how mold can and will grow.To schedule an inspection call 856-858-9509.

 

Oil tanks can be located in many different places. Oil tanks were out of sight and out of mind.  Many oil tanks can be found buried under the lawn or driveway.  Some oil tanks were buried to never been seen again, oil tanks can be buried under garage floors, decks and under the home itself such as under a sun room.  (Photo below is a tank under the floor of a room).

Oil tanks are only a problem when they leak, since leaky tanks may require remediation.  The only way to know if an oil tank is not leaking is by testing the soil under the tank.  Oil tank removal is typically your best option, since once the tank is removed, you can access soils under the tank to sample.     With tanks that are under a building, you options open up from either removal (typically possible, just expensive) to closure in place, which is the more affordable and practical option.

(Photo below shows how a tank sweep found where under the floor the tank was located)

 

Oil tank closure in place can address concerns with the oil tank, by cutting holes in the bottom of the tank (after the tank is thoroughly cleaned) and taking soil samples.

By going through the bottom of the tank you can access the soils where samples are supposed to be acquired to assess for leaks.

It's not easy work, but its cheaper than removing the tank.

The photo below shows the holes (coupons) cut in the bottom of the tank to access the soils.

Our clients hire Curren to find professional affordable solutions and with close to thirty years experience we have solved a lot of problems with oil tanks.  The photo above shows a tank under a room that we excavated, cleaned and obtained site assessment soil samples.  

This small hole was all that was required for closure in place of this tank.  Removal of the tank would have required that half the floor in the room be removed, and may have undermined the walls requiring structural support.  Curren's tank closure in place was the appropriate and lowest cost solution.

                    Why is an Oil Tank Sweep Important?

From 1900 to 1945 coal was king (coal shortages were common during WWI). By the mid 1930’s oil burners had made quality and safety improvements that made oil a competitor to coal. In 1940 more than half the homes burned coal. America oil reserves and steel making prowess from WWII allowed oil to be rapidly adopted after WWII (1945).

In the 1970’s and 80’s due to natural gas shortages and price irregularities the natural gas market become deregulated. Deregulated allowed for competition and market based pricing, which meant lower prices, this drove the popularity of natural gas. So natural gas didn’t become popular until the late 1980’s.

For homes built between 1900 and 1980, oil heat was highly probable at some point in the past (in short what were your alternate choices for heat besides oil?). Construction codes didn’t address oil tank removals until the 1990’s. Environmental regulations today have strict standards for heating oil leaks from tanks in soil and groundwater. In short, an oil tank leak can make the owner of a property a polluter so to speak. On top of that the regulations view the current owner of a property as the Responsible Party (RP) for the cleanup.

Today, you could buy a house built in 1950, that used oil until say 1980, when a conversion to gas occurred. The old oil tank was literally just left in place (abandoned), since doing anything cost money. Fast forward to 2020, you are buying that home with an oil tank that hasn’t been used in decades. If you don’t add a tank sweep with GPR (ground penetrating radar) to your home purchase due diligence you are opening your self up to a responsibility and an expense with the oil tank, as when you sell someone will do a tank sweep and find the tank you never knew you had or used, which happens all the time.

Today the internet is used not just for shopping, but for education. There are homeowners that have an oil tank on their property (used or out of service), these homeowners have learned via the internet (websites like this one) of the liability of an oil tank. We find that some people will hide the evidence of the tank and hope that no one looks for an oil tank, since the home is now heated by natural gas. Do you find it hard to believe that someone would try to hide the truth? Follow this story.

Home went under contract, home inspection and all, everything but a tank sweep with GPR was performed by the purchaser of the home. One day before settlement the prospective homeowner does a walk through of the property and low and behold someone spray painted "tank" on the ground. (this is a true story. I couldn’t make things like this up).

 

Home was a flip, so the owner (really owner for 7 months) had no knowledge of any oil tank. Curren scanned the marked area and bingo oil tank, about ¼ full of oil. We can only speculate as to why the tank was hidden and why someone spray painted tank on the sidewalk. The general theory is a neighbor was aware of a tank at that location and also aware the owner removed evidence of the tank. Presumable the neighbor removed their tank and didn’t appreciate the neighbor not doing the right thing and removing theirs. We believe this is a likely scenario as we have seen it on other sites that we have performed tank scans/sweeps. People will park cars in driveways over tanks. People will say a tank was removed and we scan the area and find a metal object indicative of a tank.

We even have people who have removed their own tanks, we get contracted to do soil borings and soil sampling from the removed tank area. $35,000.00 later, we find that the tank did leak, the owner just thought that oil is naturally present in a removed tank excavation.

 

Bottom line you cannot rely on statements from a seller such as these:

There is no oil tank.

That the tank was removed

The removed tank didn’t leak.

Do you need to complete a tank sweep? Yes, if the home was built before 1980 and you can’t get 100% written documentation that natural gas was always utilized to heat the dwelling.

Curren Environmental has been solving tank related issues for over 20 years.   Oil tanks were like cell phones, they were ubiquitous in homes in the Northeastern United States.  Oil was king as the graph shows:

 

Oil heat was more popular than natural gas up until 1980!

In 1950 43.9% of homes had oil heat

In 1960 62.9% of homes had oil heat

In 1970 52.6% of homes had oil heat

 

So in 2019, what are the odds the home your buying has or had an oil tank? Pretty high for sure.   

 

 

Tank Scans with GPR = Buyer Due Diligence

 

 

A tank scan found this tank.  You can see from the many holes in the tank, that the tank leaked.   Thankfully the home buyer had a tank sweep completed and found the tank.  The homeowner had to remove and remediate the oil tank.
