Wastewater

Abstract

Fertilizers, manure, and septic effluent are potential sources of nitrate in groundwater. Nitrate can be harmful if ingested above the U.S. Environmental Protection Agency maximum contaminant level of 10 mg/L. In Eau Claire County, located in West Central Wisconsin, approximately one quarter of households rely on private wells. Sources of nitrate in private wells in Eau Claire County have not been researched previously.

Abstract

This manual is the definitive source for information on installing decentralized wastewater treatment systems. Developed by a team of experts, this manual provides installers with training materials geared specifically to address installation—one of the many vital aspects of programs for managing decentralized wastewater treatment systems.

Updated and reviewed by leading experts in the field, this revised edition offers new coverage of industrial solid wastes utilization and disposal, the use of surveying in environmental engineering and land use planning, and environmental assessment. Stressing the practicality and appropriateness of treatment, the sixth edition provides realistic solutions for the practicing public health official or environmental engineer.

In recent years nitrogen in the environment has become a nationwide concern due to the sensitivity of many water bodies to excess nitrogen loading from many different sources, including Onsite Wastewater Systems (OWS). Complimentary to the Florida Onsite Sewage Nitrogen Reduction Strategies study, the Colorado School of Mines evaluated denitrification via subsurface via a soil treatment unit (STU). This presentation will share the rates of denitrification achieved and how to substantially increase them.
