Description:
Chemical analyses revealed that polycyclic aromatic hydrocarbons (PAH's) and other organic compounds were present in a perennial freshwater stream that flowed through the abandoned American Creosote Works, designated for Superfund cleanup by the U.S Environmental Protection Agency. tudy was conducted to determine efficacy of ultrafiltration for removal of these organics from groundwater at the Superfund site. ltrafiltration reduced the concentration of total identified organics from 210.0 mg/L in groundwater to 1.5 mg/L in the Post-filtration permeate. ests for toxicity/teratogenicity in embryonic inland silversides, Menidia beryllina; and Microtox were conducted with: treamwater, untreated groundwater, feedwater used in the ultrafiltration system and permeate water that passed through the ultrafiltration system. oncentration of 100% streamwater caused significant (a < 0.05) teratogenic responses in fish embryos and larvae. roundwater and feedwater caused significant embryo toxic or teratogenic responses at concentrations of 100, 10 and 1%; Microtox EC50's were 0.85 and 0.48%, respectively. n contrast, only 100% permeate water caused significant increases in terata.
