>Environmental Investigation


The need for environmental information arises from a variety of circumstances:
What is the Environmental condition of my property?
Is the Environmental condition of my neighbor's property affecting my property's value?
Is my underground storage tank leaking?
Has my pollution affected a Third party (i.e., State's Groundwater or drinking water)?
Is my house or office making my family or my employees sick?
These questions demand accurate, technical and professionally structured responses. Oasis has experience with addressing the above questions using the following investigational techniques:
Soil Sampling
Groundwater Sampling
Storm water Sampling
Wastewater Sampling
Air (ambient, stack, worksite)
Allergens and Mold
On and Off site investigations: File searching, interviewing, database acquisition and interpretation

To many individuals, the Environmental world is a mystery.
Terms like Phase I, 21E, SVE, Closure Report, LSP or LEP seem like a foreign language. At Oasis, we clarify this language.

The Environmental Site Assessment process is a major tool that individuals, financial institutions and Insurance companies utilize to quickly determine the environmental condition of a property. Oasis has performed hundreds of Phase I, II and III Environmental Site Assessments (ESA).

What is an Environmental Site Assessment, and where did they originate?

The American Society for Test and Materials (ASTM) Committee was formed in 1990 and currently has jurisdiction over the Commercial Real Estate Transactions Subcommittee (E50.02) has established the standards for due diligence. The term "due diligence" arose out of 1980 Comprehensive Environmental Response and Compensation and Liability Act (CERCLA). CERCLA empowers the government to seek out and hold responsible those parties who were involved in the environmental degradation of real property. Potential and current property owners concerned about this real or potential liability want to determine the following:
Whether the property has been impacted
And if so, to what degree.

The Phase I and Phase II processes provides these answers. The process is guided by the following ASTM standards.

E1527-00 Standards Practice for Environmental Site Assessments:
Phase I Environmental Site Assessments Process.

The E1527-00 is a full ESA, which involves a site, visit inspection, interviews, multiple file searches at local, State, and governmental offices, properly locating and describing the site (i.e., wetlands, flood zone) and a full report of findings. In other words, the environmental history according to what has been recorded about the property and what people know.

E1528-00 Standards Practice for Environmental Site Assessments:
Transaction Screen Process.

The E1528 is simply an abbreviated review of the site history.

E1903-97 Standards Practice for Environmental Site Assessments Phase II Environmental Site Assessments Process.

Based on the information revealed in the Phase I or Transaction Screen, a more invasive investigation may be recommended. The investigation may involve soil, groundwater, and other destructive or non-destructive sampling activities.

Results of the Phase II investigation may lead to recommendations for remediation, and that's called a Phase III. A Phase III is the process of cleaning the site.

Please note, ESA reporting requirements differ between States, and Oasis can deliver the type of report your state requires.
