Groundwater Residue Sampling Design

As the concerns over agrochemical entry into groundwater increases, so does the need for monitoring programs to determine the extent of contamination. This new volume presents information required to design a groundwater sampling program based on geostatistics and state-of-the-art sampling techniques. It examines selection of appropriate design and suitable techniques to obtain accurate data on the presence of agrochemical residues in various environmental compartments. It also provides a basis for comparing programs and data in different geographic areas with varying types of soils and aquifers. Specialized field equipment developed for the study of groundwater contamination is also discussed. Of special interest are chapters on EPA's approach to groundwater-quality monitoring and basin-scale and field-scale designs for various zones, including saturated and unsaturated zones, root zones, and vadose zones.

This book is devoted to exploring the mechanism of pesticide movement into groundwater. It describes how pesticides enter ground water/drinking water systems and how regulatory decisions based on these mechanisms will affect the use of pesticides. Experimental results, models, and industry and regulatory perspectives are covered.

This book is written in a simple, straightforward manner without complicated mathematical derivatives. Compiled by experienced practitioners, this guide covers topics such as basic principles of vadose zone hydrology and prevalent monitoring techniques. Case studies present actual field experiences for the benefit of the reader. The Handbook provides practitioners with the information they need to fully understand the principles, advantages, and limitations of the monitoring techniques that are available. The Handbook of Vadose Zone Characterization & Monitoring expands and consolidates the useful and succint information contained in various ASTM documents, EPA manuals, and other similar texts on the subject, making it an invaluable aid to new practioners and a useful reference for seasoned veterans in the field.
