Human and Ecological Health Impacts Associated with Water Reuse and Conservation Practices
Evidence of estrogenic endocrine disruption has been identified as a basin-wide issue in the Potomac River. Sources of estrogenicity at present have been attributed to agricultural land-use and point sources including waste water treatment plants. The net contribution of these sources has not been evaluated, neither has there been a collective effort to determine impacts of other water reuse and conservation practices. The work here is a collaborative effort tailored to systematically elucidate the impact of advanced wastewater reclamation, large scale stormwater harvesting and reuse, and focused agricultural stormwater best management practices on estrogenicity and other water quality parameters in the Potomac River. Collaborators include the University of Maryland; University of SUNY, Buffalo; Virginia Technical Institute; Sawyer and Hazen; and the D.C. Water Authority. The novel approach undertaken in this research combines a suite of state-of-the-art techniques to actively identify contaminant hot spots (EDCs and related biological activity, nutrients), assess the impact of those hot spots on human and ecological health endpoints (including drinking water sources and sensitive ecological areas), and quantify the impact of reuse and management solutions on these endpoints.
Objectives:
- Use multiple analytical, biological activity, isotopic, and fluorescence tracers to identify and track spatial and temporal variability in "hot spots" of contaminant sources at a watershed scale.
- Use case studies to examine impacts of advanced wastewater reclamation, stormwater reuse, and agricultural best management practices on source controls of contaminants

A USGS scientist prepares samples for the determination of estrogen equivalents using bioluminescent yeast estrogen screen.

Evidence that watershed nutrient management practices effectively reduce estrogens in environmental waters
We evaluate the impacts of different nutrient management strategies on the potential for co-managing estrogens and nutrients in environmental waters of the Potomac watershed of the Chesapeake Bay. These potential co-management approaches represent agricultural and urban runoff, wastewater treatment plant effluent, and combined sewer overflow replacements.

The Chesapeake Bay is the largest estuary in the United States and its watershed includes river drainages in six states and the District of Columbia. Sportfishing is of major economic interest, however, the rivers within the watershed provide numerous other ecological, recreational, cultural and economic benefits, as well as serving as a drinking water source for millions of people.

The observation of testicular oocytes in male fishes has been utilized as a biomarker of estrogenic endocrine disruption. A reconnaissance project led in the Northeastern United States (US) during the period of 2008–2010 identified a high prevalence of intersex smallmouth bass on or near US Fish & Wildlife Service National Wildlife Refuges that included the observation of 100% prevalence in smallmAuthorsLuke Iwanowicz, Kelly Smalling, Vicki S.
