Link to the National Contaminant
Occurrence Database via EPA's Envirofacts Warehouse
The Safe Drinking Water Act requires the development of the National
Drinking Water Contaminant Occurrence Database to provide a repository
and access to data on the occurence of contaminants in drinking water
which would support decision making for future drinking water contaminant
regulations. Sound drinking water contaminant data is the foundation
for science directed toward all levels of decisions affecting drinking
water standards.
