A Phase I Environmental Site Assessment Include?
A. Review title information of the property (provided at Client's expense), and Sanborn Maps, if available, to obtain information on past uses of the property possibly pertaining to the storage, treatment or disposal of hazardous substances.
B. Interview the current owners, employees, neighbors, government officials etc., regarding present and previous uses of the property and surrounding area, to a reasonable extent. Indicate the name of the contact and information obtained.
C. Examine readily-available historical aerial photographs and/or maps for indications of historical uses of the property, and for any evidence of potential on-site contamination, such as dumping or land filling.
D. Investigate whether the site or surrounding land within a one (1) mile radius of the site is being or has been used for any of the following purposes:
1. Agricultural (may be indicative of pesticide or herbicide used).
3. Tank/drum/equipment storage.
4. Industrial/manufacturing facility (type).
5. Oil/gas exploration.
6. Chemical/petroleum or waste storage/processing/ injection wells.
7. Military installations.
8. Fill areas.
9. Quarries/sand and gravel extraction.

E. Investigate whether there are or have been any storage tanks on the site and, where possible, what was stored in them. If possible, determine the age and the capacity of the tanks and whether a suspected release from the tanks has been reported. Determine if any existing tanks are in compliance with applicable tank laws and regulations.
Task 3 ‑ Present and Proposed Use of Property/Surrounding Land
A. Provide a Site Location Map of the area using a USGS Quadrangle Map with the site clearly identified.
B. Identify any land within one (1) mile of the site that is indicated or proposed as a permitted landfill, hazardous waste, or solid waste facility. If so, determine potential for environmental impact on the site.
C. Determine if there is evidence that water wells, in use or abandoned, exist on the property. Indicate if they are the primary source of drinking water. Specify the present and proposed method of supplying drinking water.
D. Determine the present or proposed method of sewage disposal, whether public or private. Determine if a septic system, abandoned or in use, exists on the site.
E. Provide a preliminary hydrogeological characterization of the site by reviewing soil survey maps, geological maps, topographical maps, flood plain maps and data, and any other pertinent data available for the property and it's vicinity.
Task 4 ‑ Walking Inspection of Property
A. A qualified Environmental Professional will conduct a walking inspection of the property in order to determine whether any of the following were discovered:
1. Discolored or disturbed soil areas.
2. Areas of sparse, sick or dead vegetation.
3. Drums or storage tanks (note type).
4. Discolored or polluted water; unusual or noxious odors.
5. Groundwater monitoring wells.
6. Floor drains.
7. Roads with no apparent outlet or purpose.
8. PCB containing transformers within structures or on power poles and lighting ballasts in older buildings. Other potential PCB containing material, such as soil near current or former railroad tracks.
9. Maintenance practices and hazardous materials handling procedures.
10. Any storage of significant quantities of potentially hazardous chemicals,
including herbicides and/or pesticides.
11. Potential use of lead based paint.
12. Potential wetlands and flood plains.
B. Provide documenting photographs.
Task 5 ‑ Final Report
A. Review the data developed from the field reconnaissance, agency contacts and records for technical accuracy and corroboration. Analyze and assemble the data into a final report stating conclusions and recommendations either that no further study of the site be undertaken or that a Phase II Environmental Site Assessment be initiated.
B. Determine whether there are any unique environmental factors, observations, or aspects of the site history which would justify further investigations.
What is the average length of time to complete a Phase I?
1 Average time to complete is 3 to 6 weeks. What can delay the Phase I Report?
All of the following are REQUIRED when completing a Phase I and can delay its completion.
- Open Public Records requests, if public records are available, it can take weeks to review particularly if records are held at a State agency such as the NJDEP. Appoints must be made to review these files and can take 3 to 4 weeks to schedule.
- Site visit is required with owner or knowledgeable party. This task is often put off or the owner and most knowledgeable party is unavailable, which can delay reporting.
- Questionnaire is submitted and to be completed by owner, often times this document is slow to be returned or not returned, leaving a data gap in the report.
It should be noted that a warranty on the environmental condition of the site cannot be provided, nor a guarantee of any kind. The report provided will represent professional opinion based upon the information disclosed by the Client and available in public records, together with the application of standard scientific field investigation methods. It must be recognized that at the completion of the Phase I ESA, there may be unresolved issues regarding the possible contamination of the site, or the potential presence of suspect materials. Based upon preliminary findings of the Phase I study, the Client will be immediately informed of any suspect or unusual conditions which may result in a recommendation for a further study.
