Clean and dependable supplies of water are critical to ensure a high quality of life and maintain a strong economy.  Groundwater is of particular importance since it is the primary source of water for many Fond du Lac County residents and industries.

While municipal water supplies are subject to strict guidelines and water quality testing to ensure that water meets the criteria for safe drinking water; the thousands of household wells which serve as the primary water supply for rural residents are not routinely tested.  These private well owners often know little about the quality of their well water and little information is available to assist them in identifying concerns.  

If not carefully monitored, managed and protected, high-quality groundwater can be depleted or significantly degraded.  When our clean water is degraded, it is often a time consuming and expensive process to determine where to locate the next well or how to obtain a safe supply of water.
