Talk Outline • Review What Emerging Contaminants Are • Discuss New York Wastewater Data • Show ongoing Research on ECs
Emerging Contaminants: Highly used unregulated compounds, often suspected of acting as endocrine disruptors Include: Pesticides (2,4-D) Pharmaceuticals (Fluoxetine) Detergent Degradates (para-Nonylphenol) Fragrances (AHTN) Others (Triclosan, fire retardants)
USGS Method SH1433 SH1433
Plant Secondary Biological Treatment Tertiary Treatment Disinfection A Extended Aeration Activated Sludge Sand/Anthracite Microfiltration Ultraviolet B Extended Aeration Activated Sludge Sand Filtration Chlorination/ Dechlorination C Two Stage Activated Sludge Sand Filtration Chlorination/ Dechlorination D Trickling Filter Sand Filtration Chlorination/ Dechlorination Wastewater Treatment Plants
Removal of Selected Compounds • Activated sludge plants seemed to perform well • Trickling filter plant (D) significantly less successful
M&E-USGS Research Partnership • Research Agenda • Stage 1 • Baseline Evaluation of Emerging Contaminants • Stage 2 • Focus on Wastewater Treatment Processes • Characterize Influent and effluent concentrations • Seasonal variation • Upstream and downstream concentrations • Individual treatment processes
Pharmaceutical/Antibiotic Flame retardant/Plasticizer Fragrance Pesticide Plant/Animal steroid Detergent metabolite PAHs Others P. Stackelberg – NJ Study of ECs in Finished Water 3 to 15 compounds detected per sample
2.1 ng/L E2 1.4 ng/L E2 <0.8 ng/L E2 2.9 ng/L E2 1.2 ng/L E2 Research - Boulder Creek, CO Study • Hormone levels elevated downstream of WWTP • Fish community and fish health assessment to be • conducted (USGS / University of Colorado)
Emerging Contaminants • Poorly understood • Have potential to affect fish reproduction • May be accumulating in sludge • Can be removed by advanced wastewater treatment
