Optimizing short - and long-term dechlorination through in situ pH adjustment
The process of enhanced reductive dechlorination (ERD) creates an anaerobic environment conducive for microbially-mediated biodegradation of chlorinated solvents. When aquifer pH is too low or too high, these microbes do not function effectively. Buffering the groundwater and aquifer increases microbial activity and results in higher dechlorination rates. With standard ERD approaches, site pH may decrease, and commonly used buffers can develop high concentrations of aquifer sodium, leading to regulatory ... |

Brownfields redevelopment; Understanding your environmental responsibilities
Brownfields are properties that have, or may have, contamination or the stigma of contamination that hinders the reuse of land for new development. The lure to these properties is great – seemingly prime, large tracts of land being sold for relatively inexpensive prices; the vision of unrestricted development; putting residential communities on these lands and reaping a great return. To further entice the prospective buyer, the government offers reimbursement programs for qualified properties, through ... |
