In the month of November, the City of Spearfish Utilities Department will begin its participation in the Fourth Unregulated Contaminant Monitoring Rule (UCMR4).

So what does all this mean for our customers in the City of Spearfish? Our Utilities Department will be taking samples of the water produced at our 7 Madison Aquifer wells and throughout the city’s distribution system. These samples will be sent to an approved laboratory and analyzed for the list of chemicals required by the UCMR4 program. The results will be included in the national database and will be made available to you, our customers. We are confident in the quality of our drinking water in Spearfish. Using then Madison Aquifer as our water source, we continue to have some of the best water in the state and nation. All of our test results and annual reports are available on the city website.
More information about this program and the test results will be available on the City of Spearfish Website under Public Works, Water, Water Reports, UCMR4 information. City staff will also be available to discuss this and other Drinking Water information, as requested, for homeowner association groups, business/civic group meetings and individually. To schedule a meeting, please contact the Public Works office at 605-642-1333.
