Description Nitrate groundwater contamination is a potential public health issue in Benton County. An understanding of the potential contaminant sources and pathways are not well characterized or understood for the county’s groundwater supply. Before an effective and targeted management program can be built, the magnitude and extent of nitrate contamination within the county must first be characterized. This project, to be implemented by the Benton Conservation District, will help build that foundation through the targeted and systematic collection of new sampling data from approximately two-hundred groundwater wells. The new data are to be collected seasonally over the course of the two-year study to help identify the influence of potential nitrate sources or nitrate dilution sources (such as irrigation water) and seasonal changes to the groundwater nitrate contaminant levels. This Quality Assurance Project Plan (QAPP) governs the methods, study design, and data quality procedures for the Benton County Groundwater Nitrate Monitoring Study.
