DARAMENDTM - Bioremediation of Organochlorine Pesticides via In-Situ Chemical Reduction
As cities and communities grow, the need to remediate and use brownfields and greenfields increases. Former agricultural land can often be impacted with chlorinated pesticides, or more specifically, organochlorine pesticides. These include compounds such as DDT (Dichlorodiphenyltrichloroethane), DDE, DDD, Dieldrin, Toxaphene, and many others. Although use of most of these compounds has been discontinued in most countries, they persist in the environment due to their relatively low volatility and high resistance to biodegradation. Adventus has developed a soil bioremediation process using their proprietary DARAMEND soil amendment. This process has been used to treat over 3.5 million tons of soils contaminated with pesticides, organic explosives, polynuclear aromatic hydrocarbons (PAHs), etc. A case study will be presented for a former agricultural area that was being converted to residential use. Bioremediation was conducted on an area of over 30 acres, where soil was impacted with low levels of pesticides. The traditional approach for remediation of this type of soil contamination has been excavation and off-site disposal at a landfill. At this site, however, the decision was made to treat the soil on-site using a bioremediation process known as in-situ chemical reduction (ISCR).
