Groundwater from the Columbia South Shore Well Field (CSSWF) is an important part of the drinking water supply for Portland and the metro region. Groundwater helps meet higher summer water demands and provides drinking water during emergencies or when Portland’s primary water source, the Bull Run watershed, is not available. The well field also makes Portland’s water system resilient in the face of drought and climate uncertainty.
To keep the groundwater from Portland’s production wells clean, the Portland Water Bureau partners with the cities of Fairview and Gresham to implement a Groundwater Protection Program throughout the CSSWF. The CSSWF Wellhead Protection Area Reference Manual lays out the pollution prevention requirements that apply to hazardous materials management in the well field. The manual was last updated in 2010 and is due for some minor upkeep. The biggest changes concern the annual reporting process for regulated businesses.
