Bioremediation


WC Environmental, LLC produces a proven product, Pimonas® Microbial Solution, that can meet your bioremediation needs! While there are a number of technologies to clean up spills or releases of petroleum to soil or groundwater, bioremediation is the one method that is so safe and proven that the PA Department of Environmental Protection offers training courses in the subject. Bioremediation is the least expensive of all the generally accepted methods of cleaning up petroleum releases.

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


Q: Is it safe?
A: Yes! Oil-eating microbes are non-hazardous, non-toxic, and biodegradable. Bioremediation technology has been in use for nearly 70 years!

Q: What happens to the microbes when there is no more oil or gasoline for them to consume?
A: Like all organisms, they will die when their source of food is eliminated. Microbes decompose to carbon dioxide, water, and trace elements.

Q: If these micro-organisms are already present in soil naturally, won't the microbes at my site eventually decompose the petroleum contamination?
A: 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.

Q: What are considered ideal conditions for bioremediation of soils and groundwater?
A: 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!

Q: How much Pimonas® do I need for my project?
A: Our studies show that one gallon of solution will typically treat about 4 cubic yards of soil/water.

Q: How long does it take?
A: 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.

Q: What are the advantages of bioremediation over other technologies such as pump and treat or soil washing?
A: 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.
