Contents Notes
From February through April 2010, EPA conducted sampling of drinking water wells and potential sources of nitrate contamination in the Lower Yakima Valley, which is in Yakima County in central Washington State. The Yakama Reservation composes a large percentage of the Lower Yakima Valley. EPA’s effort entailed collecting over 331 samples from residential drinking water wells for nitrate and bacteria, and multi-parameter sampling on 29 water wells (26 residential drinking water wells and three dairy supply wells), 12 dairy lagoons (15 samples), 11 soil samples (five at dairy application fields and six at irrigated and fertilized crop fields1), five dairy manure pile samples, and three wastewater treatment plant (WWTP) influent samples. This report presents the results of these sampling efforts.
