Description The Lower Yakima Valley Groundwater Management Area (GWMA) Ambient Groundwater Monitoring Network is designed to assess the condition of the aquifer over time. The Department of Ecology will collect nitrate samples from 170 wells, spatially distributed across the GWMA. To characterize seasonal variability, samples will be collected quarterly for two years (July 2021-April 2023) and collected annually thereafter. This assessment will provide the data to statistically determine trends in nitrate concentrations across the aquifer over time.

This project was funded by the Washington State Legislature to continue the work of the GWMA and implement the top recommendation: Establish an ambient groundwater monitoring network and collect data.
