Landfarming applications are the easiest, most controllable method of bioremediation. ETEC has completed hundreds of on-site landfarm projects via a combination of effective biological amendments and proper soil management. ETEC does not provide soil tilling services (we leave that to a qualified contractor), but we can provide on-site application of biological amendments, and we work closely with the tilling contractor to ensure that optimum soil conditions are maintained throughout the life of a project (usually 2-4 months). Effective soil management includes monitoring and maintaining appropriate soil pH and soil moisture (extremely critical), and consistently turning and tilling the soil to maximize pore space oxygen content and ensure complete mixing and contact.

Our PetroBac bioenhancements provide pre-activated biomass and a light biosurfactant that can be sprayed directly onto the soil matrix to achieve optimum contact and continuous “cutting” of even the most recalcitrant petroleum compounds (like heavy oils). Our CBN™ nutrient product provides required macro- and micro-nutrients for microbial functions, as well as secondary electron acceptor mass (nitrate and sulfate) to support factultative degradation of contaminants when oxygen is absent. Soil contaminants we have successfully treated include the following: |

Our success is based on two factors: 1) effective biological amendments, and 2) hard-earned field application and soil management experience. We understand how to apply our amendments to achieve the proper microbial conditions, and we understand the fact that different contaminants require different amendments in order to achieve fast, effective biodegradation. |
