In order to prevent future contamination of Hopkins' municipal wells, the City recently completed a wellhead protection plan that will help City staff guard against undesirable land use or existing public or private well activity that could affect our invaluable groundwater aquifer.

Additions to the Water
The City adds chlorine to control taste and odor and keep the water system bacterially clean.
Corrosion control in the water system is handled by the addition of the LPC-9 Corrosion Inhibitor; it creates a barrier inside the plumbing that reduces the transfer of lead from the solder, and copper from the pipes into the drinking water systems.
Fluoride is added to the water to help prevent tooth decay. The level of fluoride is kept at 0.5 to 0.9 parts per million as mandated by the Minnesota Department of Health.
The City's water is 21 grains of hardness, and has less than .03 parts per million of iron after filtering.
