Non-transient/Non-community Water Systems
Regulated Contaminants and Maximum Levels
These types of system provide drinking water in places that serve the same people day after day outside of their homes. These consumers are at risk for cumulative, long-term exposure to contaminants, and the regulated contaminant list reflects this. To meet these requirements, Neilson Research Corporation provides routine analysis for schools, hospitals, and work places that have a water system of their own. Our staff provides unquestionable data to satisfy regulatory authorities under the Safe Drinking Water Act.
