Water Quality Monitoring

Water systems are responsible for conducting monitoring of drinking water to ensure that it meets all drinking water standards. Laboratories analyzing drinking water compliance samples must be certified by USEPA of the State. Here is a list of Laboratories Certified for Drinking Water Analyses.  Specifically, a list of laboratories that perform microscopic particulate analysis (MPA) testing can be found here.

The frequency of monitoring is often dependent on the contaminant and the population served by the public water system. Public water systems serving large populations generally require more monitoring because of the greater potential impact of violations.

Primary standards protect public health by limiting the levels of contaminants in drinking water. For a complete list of primary contaminants see Table 6-1 of the Water Supply Rule

Secondary standards protect public health by limiting the color, taste, odor, and visual appearance of the drinking water that my cause consumers not to drink

or use the water, even when it is actually safe to drink.  For a complete list of secondary contaminants, see Table 6-2 of the Water Supply Rule
