Abstract

Anthropogenic Chemicals in the Source and Finished Water From Three Mississippi Communities That Use Surface Water as Their Drinking-Water Supply

Author(s): Rose, C. ;  Coupe, R.;  Smith, C.

The U.S. Geological Survey, in cooperation with the Mississippi Department of Environmental Quality, began a sampling program in the fall of 2007 to analyze water samples for a suite of wastewater indicator compounds and pesticides for the three drinking-water facilities in Mississippi that use surface water from the Pearl, Tombigbee, and Tennessee Rivers as their source water. Three samples, from both source water and finished water, were collected from each facility in October 2007, and January and May 2008. Few wastewater indicator chemicals were detected in source water; however, low concentrations of some commonly used herbicides were detected in the source and finished water from all three facilities. None of these compounds were detected in finished water at or above established drinking-water standards. Modern society depends upon chemicals to prevent and combat disease, cleanse and soften skin, smell better, reduce wrinkles, influence moods, and control weeds and insects for safety and aesthetic reasons. These compounds, which can be found in any drug or hardware store, enter the environment through runoff from agricultural fields, urban lawns, highway rights of way, parks and recreational areas, domestic sewage, and other sources. Some of these compounds have been shown to be stable in the environment, and also have been shown to survive the conventional drinking-water treatment process and be detected in the finished drinking-water supply. Little is known about the abundance and persistence of these compounds in surface waters of Mississippi; hence, there is little information on what effect further development in basins upstream of source-water intakes will have on downstream communities that rely on surface water as their source for drinking water.

Workshops

Responsible Site Design: Implementing Innovative Stormwater Management Strategies

The primary goal of the workshop is to create a dynamic learning experience that examines the role of stormwater management in the built environment. The workshop will focus on integrating ecologically sound water management approaches into site design. After the workshop, attendees will be familiar with the following concepts and technical issues:

  • Knowledge of the stormwater treatment chain
  • Knowledge of the impact of land use codes on stormwater management
  • Application of a design process that mitigates the effects of stormwater on-site
  • Knowledge of the relationship between land use codes and design for innovative stormwater management
