Roughly half of the county’s population receives water from groundwater sources known to you as, public water utilities. Port Washington, and parts of Mequon are cities that get their water supply from Lake Michigan. Ozaukee County is not limited to just public water utilities, and Lake Michigan water. For those of you living outside the city limits, there are a few systems with groundwater wells to supply drinking water to subdivisions, apartments, condominiums, and institutions.

Arsenic in Ozaukee County Water

While understanding where your water comes from is extremely important, you may be wondering, what Arsenic is exactly? Arsenic is a harmful substance that is found in soil and rock. Under certain conditions, Arsenic can find its way into groundwater, eventually making its way to your kitchen sink. Municipalities routinely test for water contaminants, but if you receive water from your private well, then it is the homeowner’s responsibility. Due to Arsenic being common in Ozaukee County, it should be tested for on a yearly basis to keep your family and pets safe. Guthrie & Frey offers a water exam to homeowners in Ozaukee County that tests for arsenic and other contaminants.
