Legislative Authorities for Water
• Clean Water Act (1977)– Sets water quality criteria and guidelines and technology-based standards for ambient water– Objective is to restore and maintain the
chemical, physical and biological integrity of the Nation’s waters
• Safe Drinking Water Act (1974), amended 1986, 1996
– Requires EPA to set maximum levels for contaminants in water delivered to users of public water systems.
– Goals• Develop a planning framework for Federal research related to human health
and ecological effects of endocrine disrupting compounds• Identify research gaps and develop a coordinated plan to address priority
research needs
EPA Research and Studies
• Office of Research and Development– NCER: STAR Grants Program– Research targeted at development of new chemical
analysis methods, improved waste treatment, aquatic effects and new approaches for prioritizing chemicals for monitoring
– Endocrine Disruptors Research Program
EPA Research and Studies cont…• Office of Water
– National Pilot Study of PPCPs in Fish Tissue• Principle Goals
– The purpose of the study is to investigate the occurrence of PPCP chemicals in fish tissue from effluent-dominated streams at five locations in various parts of the U.S.
• Study Design– Collecting fish samples from 5 effluent dominated streams
from various locations across the country– Collecting 18 to 24 fish in the vicinity of wastewater treatment plant discharges– Validated analytical methods available for 37 PPCP compounds (24 pharmaceuticals, 13 personal care products)
EPA Research and Studies cont…• Office of Water cont…
– Publicly Owned Treatment Works Study• Principal Goals
– Establish baseline for POTW raw wastewater characteristics and characterize performance of an expanded list of pollutants for various treatment technologies
– Priority (toxic), conventional and non-conventional pollutants
• Study Design– Sample 9 POTWs with secondary treatment or better – Sample influent and effluent– Collect available information and identify data gaps – Identify emerging pollutants of interest– Develop/refine analytical methods
EPA Research and Studies cont.• Office of Water cont…
– National Targeted Biosolids Survey• Purpose
– Gather information to update assessment of risks from pollutants in sewage sludge
• Study Design– Random selection of 75 POTWs– Sampling for presence and concentration of metals, 9 chemicals, and up to 59 PPCPs and flame retardants– Currently developing methods for identification and
quantitation of three classes of PPCPs and estrogen-related compounds that persist in biosolids.
Opportunities for Collaboration
• Data sharing with various agencies (e.g.-USGS, CDC, FDA, USDA)– Occurrence and health effects data
– To develop water quality standards/criteria– To develop drinking water regulations – To assess increasing antibiotic resistance– To develop effluent guidelines
• Collaborate with Federal/non-Federal partners in targeting research and testing to fill data gaps to support criteria development and regulatory actions
• Broaden collaboration with USGS on methods development and monitoring
