Potential Contaminant Inventory

Protection Activity: Planning

A potential contaminant inventory (PCI) is an inventory of facilities, land uses, and environmental conditions within a source water protection area that are potential sources of contamination to ground water or surface water. DEQ is required to conduct a PCI for each source water assessment it completes. All available PCIs can be found on DEQ's source water assessment web application and be used to develop protection strategies or determine site suitability for new well locations.
