WCWC has assembled an interactive map to assist with finding a laboratory based on the type of sample being analyzed and geographic location. Different layers on the map show locations that can test for microbiological, organic chemical, inorganic chemical, radiological or physical parameters. This map was prepared from the list updated online as of June 8, 2022. This map can be viewed below.
