Groundwater in the Lower Yakima Valley contains elevated levels of nitrate. While nitrates do not cause health issues for most adults, some people may be at greater risk due to their age or certain health conditions.

Local and state agencies have partnered through the Groundwater Management Area project to reduce nitrate levels in groundwater and ensure Lower Valley communities have clean drinking water.
