Phase I Environmental Site Assessments
ASTM 1527 Phase 1 Environmental Site Assessments (ESAs) are completed by a certified individual who has performed over 500 site assessments. The ASTM standard is designed to meet the liability concerns of third party lenders. Lead time is normally 10 days to two weeks for completion of the survey and report. Phase 2 ASTM surveys are completed when there is reason to believe that subsurface contamination may be present.
Phase 1 Environmental Site Assessment Process (ASTM E-1527-00)
includes the following:
WC Environmental can perform an ASTM 1528 site assessment and produce a report for as little $350.00 on a residential property and $600.00 on a commercial property. The cost includes historical titles search (back a minimum of 60 years), color site photography, site search for erosion concerns, review evidence of underground storage tanks, evaluation of soil and of other environmental issues, conclusions and recommendations. We have completed environmental audits on residential, commercial, farm, health care, educational, and industrial properties. Numerous references are available. ALL SURVEYS ARE PERFORMED BY A CERTIFIED ENVIRONMENTAL INSPECTOR.
Transaction Screen Process (ASTM E-1528-96) includes the following:
Financial Assistance Available
There are a variety of grant and loan programs available to help pay for site assessment and/or cleanup activities associated with contaminated properties. We will gladly assist you in evaluating and applying for these programs.

Most people are aware that there are microbes everywhere; many of these microbes are found in oil-producing areas. These microbes, which consume oil as their "food", can be removed from soils and engineered in the laboratory to reproduce readily. Pimonas® Microbial Solution is a highly concentrated form (billions per gram!) of these microbes. Bioaugmentation involves placing Pimonas® Microbial Solution in soil and groundwater where contamination is found. While these microbes do have other survival requirements (enough air and water), what they need most is petroleum hydrocarbons for food! There are thousands of documented success stories - bioremediation is effective. Depending on specific soil and/or groundwater conditions, contamination can be gone in an amazingly short time, from several weeks to a few months.
If you are unhappy with the costs associated with traditional "pump and treat" technologies, we hope you will consider using Pimonas® Microbial Solution at your site and watching how quick our microbes go to town on your contamination! Pimonas® Microbial Solution is not only safe and fast, it is also priced less than many competing products and technologies.
Frequently Asked Questions about Bioremediation
1. Is it safe?
Yes! Oil-eating microbes are non-hazardous, non-toxic, and biodegradable. Bioremediation technology has been in use for nearly 70 years!
2. What happens to the microbes when there is no more oil or gasoline for them to consume?
Like all organisms, they will die when their source of food is eliminated. Microbes decompose to carbon dioxide, water, and trace elements.
3. If these micro-organisms are already present in soil naturally, won't the microbes at my site eventually decompose the petroleum contamination?
If soil and groundwater chemistry conditions are ideal, then "natural attenuation" may work. However, the most effective microbes for attacking petroleum are found in soils in oil-producing areas. "Bioaugmentation" - the addition of concentrated oil-eating microbes not found in native soils - works much faster. Pimonas® microbial solution, for instance, has billions of microbes per milliliter, and confluent growth will continue as long as conditions are appropriate.
4. What are considered ideal conditions for bioremediation of soils and groundwater?
Without getting too technical, the key factors are temperature, oxygen level, and pH. Microbes do not do well in cold conditions, they like high dissolved oxygen levels (silty or sandy soils, not heavy clays), and a neutral pH. They are surprisingly hardy, though, particularly if they have plenty of food!
5. How much Pimonas® do I need for my project?
Our studies show that one gallon of solution will typically treat about 4 cubic yards of soil/water.
6. How long does it take?
We have seen successful results in as little as a week, but larger projects may take several months and require two or three applications. Contaminated surface soils can be cleaned up in as little as two days.
7. What are the advantages of bioremediation over other technologies such as pump and treat or soil washing?
The primary advantages are time and money. Bioremediation typically works much faster, and at a cost of between $15 and $30 per cubic yard (depending on number and size of applications), it is usually much less expensive than alternate technologies.
