What is bioremediation?
Bioremediation is a naturally occurring process where small organisms called microbes, through a biological process clean up contaminated soil, groundwater and even hard surfaces. Bioremediation facilitates the growth of microbes that use contaminants as a source of food and energy.
Bioremediation has been successfully used to clean up many polluted sites including retail and commercial businesses, personal residences. It has also been used in the treatment of notorious spills such as the 2010 BP Deepwater Horizon and the 1989 Exxon Valdez spill.
How long does it take?
The biological activity starts immediately, but visible results can take weeks, or even months for microbes to clean up a site depending on the amount of contamination. Primary influential factors are the volume of contaminants, the number of microbes present, and the environmental conditions mentioned above.
Bioremediation on concrete:
Bioremediation can be used on the surface of concrete to remove petroleum stains such as oil, diesel, gas, fatty oil and grease (FOGS) and more, eliminating the need for pressure washing or detergents.
When a bioremediation product is applied to a contaminated area, the enzymes and other active ingredients help to break up the stain on the surface. Unlike traditional methods, bioremediation penetrates deep into the pores of concrete to completely remove contaminants.
Multiple applications may be required for large or older stains. Make sure to allow sufficient time for bioremediation products to completely remove the stain. Still not sure? Contact one of our CAF Outdoor Cleaning specialists and get the lowdown on how to clean those dirty locations.
Bioremediation uses naturally occurring microbes and poses no threat to people, plants and animals at a cleanup site. Bioremediation reduces the amount of equipment, labor and energy used to clean up contaminants, and is the recommended method for removing oil contamination by the United States Environmental Protection Agency.
Many states, cities and municipalities prohibit pressure washing petroleum stains without reclaiming the water run-off as hazardous waste. Non-compliance can result in substantial personal and business fines and even criminal charges.
