Washington County Water

You’re in luck! Guthrie & Frey is proud to service the beautiful area, known as, Washington County. You may wonder why you need our help? Well, thousands of years ago, 2 glaciers collided forming the hills, lakes, flat farmlands, and swamps of Washington County and the Kettle Moraine Area – depositing sand, gravel, silt, and clay over ancient bedrock.  The deposits created various groundwater aquifers: sand and gravel, limestone, and sandstone, that now supply water to all of Washington County.

While most residents get their drinking water from municipal wells, over 10,000 homes in the area have private wells. Municipal and private wells provide their own unique challenges that vary based on the depth of your well indicating what contaminants will be in your water.

Water Challenges in Washington county:

Due to the landscape in Washington County, finding Limestone in your water can be a common issue. Typically, it is the first layer of bedrock, allowing groundwater to quickly flow into the fractured limestone, easily entering wells before being treated. Limestone is not harmful to your health, but you will notice a white powder layering on your dishes, sink, and faucets which tends to be a nuisance.

Many Washington County homeowners notice their water has a strong smell to it, they notice stains on fixtures and appliances, or their water just doesn’t taste as crisp as they’d like due to the contaminants residing in it. Water softener companies like Guthrie & Frey have been serving your neighborhoods in the Washington County area for over 45 years to protect your homes from water contaminants.

Hard Water in Washington County

Hard water is not uncommon in Wisconsin, and although it is not likely to have a negative effect on human health (in small amounts), it does cause a buildup in appliances and pipes within your home. If the buildup becomes too much, it can cause problems in appliances, resulting in sometimes needing a full replacement. Knowing how hard your water is can help prevent these issues from arising. Water is measured in grains of hardness – the higher the number, the harder your water is. Washington County water typically has 20-100 grains of hardness. Whereas soft water is typically below 1 grain of hardness and helps to prevent appliance issues and failures.
