Private Water Systems
The Washington Ozaukee Public Health Department does not sample private well water but we do recommend testing your private well yearly for potential contaminates. If you are looking to test your private well for various contaminants such as bacteria, nitrates, arsenic and other metals the following link provides labs that have kits available for purchase. Call or visit their websites to order kits and obtain specific prices.

Public Water Systems
Public water systems are usually operated by a municipality. These systems are tested on a regular basis by municipal workers and must comply with strict Environmental Protection Agency (EPA) and the Wisconsin Department of Natural Resources (DNR) standards. If you have questions about your municipal water supply, call your local city or village hall.

Businesses and schools that serve water to the public are also regulated under the following DNR programs:
• Transient, non-community well water program: Small Businesses, Campgrounds, Restaurants, Taverns, Churches, Golf Courses, and Convenience Stores
• Non-Transient, non-community well water program: Schools and Large Businesses
• Other than Municipal, Community: Subdivisions and Mobile Home Parks

The Washington Ozaukee Public Health Department samples water from small businesses, campgrounds, restaurants, taverns, churches, golf courses, and convenience stores that use well water. You can look up water test results on the DNRs website: Wisconsin DNR Drinking Water Data
