Emerging contaminants (ECs) are chemicals such as pharmaceuticals and personal care products that have been detected in various environmental matrices, including drinking water supplies at trace concentrations (ng/L-ug/L or ng/kg-ug/kg). Current wastewater treatment plant technology is largely ineffective at removing ECs. The objectives of this investigation were to: 1) determine the occurrence of ECs in private well water supplies in Montgomery and Roanoke County, VA 2) quantify the concentrations of three ECs in selected private water supplies; 3) examine the relationship between water quality constituents (nitrate, bacteria, pH and total dissolved solids) to EC occurrence in private water supplies; and 4) determine the ability of the MicroEvapTM, a novel wastewater treatment technology, to remove ECs from secondary wastewater effluent. In partnership with the Virginia Household Water Quality Program, 57 private water supplies were sampled and tested for the occurrence of 142 ECs and 43 other water quality constituents. Up to 73 ECs were detected in the sampled private water supplies. Higher numbers of ECs detected in the tested private water supplies were related with nitrate >1 mg/L, total dissolved solids >250 mg/L, and the presence of total coliform bacteria. Results indicate the MicroEvapTM technology had >99% removal effectiveness for all 26 tested ECs from three secondary wastewater effluent. With the increasing detection of ECs in water bodies, it is essential to understand the occurrence of ECs and environmental predictors of EC presence in different water matrices and continue to develop water treatment technology capable of treating wastewater for EC removal. / Master of Science / Emerging contaminants (ECs) are compounds intended to improve human and animal well-being, and include pharmaceuticals, personal care products, and human/veterinary antibiotics. ECs have been frequently detected in water resources worldwide including drinking water. The release of ECs from wastewater treatment plant (WWTP) effluent is their primary route into the environment. The inability of most current wastewater treatment technologies to fully remove ECs necessitates further development of technology that can effectively remove ECs. Emerging contaminants such as pharmaceuticals enter WWTPs because the human body does not fully metabolize the compound and the remainder exits in waste. Private well water is largely unregulated and often untreated and has been relatively less evaluated for EC presence in the literature. The objectives of this study were 1) determine the occurrence of ECs in private well water supplies in Montgomery and Roanoke County, VA 2) quantify the concentrations of three ECs in selected private water supplies; 3) examine the relationship between well age and depth and water quality constituents (nitrate, bacteria, pH and total dissolved solids) to EC occurrence in private water supplies; and 4) determine the ability of the MicroEvap™, a novel wastewater treatment technology, to remove ECs from secondary wastewater effluent. Emerging contaminants were detected in southwest Virginia private well water. Knowing the ECs present in private well water is necessary to allow for eventual human risk assessment of ECs for people consuming the water. The MicroEvap™ was highly effective at EC removal from wastewater with removal rates >99%. The removal of all ECs from wastewater is essential to ensure purified WWTP effluent. The continued detection of ECs and the unknown human health risks from these contaminants in drinking water means ECs are a significant pollution concern that requires continued assessment.
