Description

This time-saving book provides extensive coverage of all important aspects of nitrates in groundwater, ranging from prevention to problem assessment to remediation. It begins by highlighting the nitrogen cycle and related health concerns, providing both background information and a unique perspective on health issues. It then analyzes subsurface processes and the factors and practices that affect them. It thoroughly reviews aquifer vulnerability mapping, an emerging new management tool, and contains a nitrate pollution index that can be used in evaluating actual or potential nitrate pollution from agricultural areas. Best Management Practices are described and evaluated, and possible treatment measures are also explored. Thoroughly researched and well-organized, Nitrates in Groundwater provides a vivid snapshot of the status of nitrates in groundwater today.
