Due to the dissolution of San Juan Basin Public Health, homeowner water testing will take place at the La Plata County Water Quality Lab in Durango, Colorado. La Plata County Public Health’s Water Lab provides water testing for residents of Southwest Colorado. Water bacteriology testing determines the absence or presence of total Coliform and EColi Bacteria. The water lab also provides testing for public wastewater systems. The Department of Public Health & Environment (CDPHE) also conducts these services. The Colorado State Public Health Laboratory’s chemistry and environmental microbiology programs work together to test water so that is safe to drink.
