Description
This guideline outlines recommended and preferred protocols to construct, install and develop groundwater monitoring wells at confined feeding operations (CFOs), which are regulated under the Agricultural Operation Practices Act (AOPA). Materials and methods presented are preferred and acceptable for typical situations. Other methods and materials may be acceptable under specific situations, based on the judgment of qualified professionals. Monitoring wells must be constructed, installed and developed by knowledgeable and experienced individuals under the guidance of a suitably qualified professional. Groundwater monitoring refers to the monitoring of local groundwater resources to evaluate changes in chemical, biological and physical characteristics. It includes periodic sampling and analysis to detect changes in constituents in groundwater and periodic measurement of water levels to determine the direction of groundwater flow.
