From September through November 1994, the U.S. Environmental Protection Agency (EPA) conducted afield demonstration of the remediation of highly contaminated groundwater at the Nascolite Superfund sitelocated in Millville, New Jersey. Besides high concentrations of the major contaminant, methyl methacrylate(MMA), the groundwater also contained small amounts of volatile and semivolatile organic compounds.ZenoGem® technology, an integrated bioreactor and ultrafiltration membrane system, was employed for thisdemonstration project. Approximately 30,000 gallons of groundwater containing MMA in concentrations of 567 to9,500 milligrams per liter (mg/L) and chemical oxygen demand (COD) values ranging from1,490 to 19,600 mg/L was treated. The demonstration focused on the system's ability to remove MMA andreduce COD from the groundwater. Results of the three‐month demonstration showed that average MMA and CODremoval efficiencies were greater than 99.9 and 86.9, respectively. The total cost of treatment, depending onthe duration of the project, is estimated to vary from $0.22 to $0.55 (in 1994 dollars)per gallon of groundwater treated. © 2001 John Wiley & Sons.
