Schools, Offices, Factories, and Child Care (Nontransient)
Noncommunity Public Water Supply

The information on this page is for facilities such as schools, offices, factories, and child care facilities that serve at least 25 of the same people over six months of the year.

This is considered a nontransient water supply. These facilities are tested at least annually for total coliform bacteria and nitrate. They are also tested for contaminants such as pesticides, solvents, and metals. Contaminants are tested at different frequencies. The frequency will depend on the type of contaminants and the previous results.
