Evaluation of the Development and Effectiveness of Copper Total Maximum Daily Loads (Tmdls) to Achieve Marine Water Quality Criteria
… concentrations of certain chemicals in surface water are known to be toxic to aquatic organisms (e.g., barnacles, algae, and fish). For a number of these chemicals (e.g., tributyltin [TBT], copper) federal and state water quality standards exist to protect aquatic organisms. As a means to comply …

The Use of Selected Water Quality Parameters to Identify Fecal Coliform Sources in Support of the Sinking Creek Total Maximum Daily Load.
… is on the 303(d) list for not meeting minimum water quality standards for recreation. A Total Maximum Daily Load (TMDL) for fecal coliforms was developed. The purpose of this study was to investigate the use of water quality parameters to identify areas that contribute to the fecal coliform …

Inventory and analysis of proprietary, small-footprint storm water best management practices
According to the 2000 National Water Quality Inventory Report to Congress, over forty percent of our nation's lakes and rivers still do not meet water quality standards. Urbanization is one of the main causes of poor water quality in America. Increased impervious surface area due to new buildings …

Acute Toxicity of Ammonia and Copper to Mussel (Bivalvia: Unionidae) Glochidia Inside and Outside of Conglutinates
Regulations regarding the allowable limits of water pollution are often based on the levels of those pollutants that are toxic to the most sensitive freshwater organisms. Freshwater mussels (Unionoida) are unusually sensitive to certain pollutants and therefore have potential to drive water quality …

An Examination of the Reference Watershed Approach for TMDLs with Benthic Impairments
This research addresses the Reference Watershed Approach (RWA) in the TMDL process for benthic impairments. In the RWA, do different land use sources (DOQQ and NLCD) or use of alternative water quality models (GWLF and SWAT) result in different stressor loadings? Is there a difference in stressor …
