Water Quality Monitoring

Water systems are responsible for conducting monitoring of drinking water to ensure that it meets all drinking water standards as determined by its monitoring schedule, which can be checked via the database below. 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 violationsPrimary 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.  In addition, see USEPA RULES.

Laboratories analyzing drinking water compliance samples must be certified by USEPA of the State and more information is available here.  Specifically, a list of laboratories that perform microscopic particulate analysis (MPA) testing can be found there as well.

Microscopic Particulate Analysis (MPA) is used to determine if a Groundwater Source is Under the Direct Influence of surface water (GWUDI). For more information, visit the Source Water Protection page.
