50% Off Private Well Water Test Kits

Posted on July 20, 2023 at 9:38 AM by Public Health Blog Team


Does your home have a private well? During these hot Wisconsin days, how do you make sure that the water you’re drinking is safe? Test it! Water kits are available at Walworth County Health & Human Services year-round, but for the month of July, these kits are available at a discounted price – a whopping 50% off! 


Testing your private well is a way to identify any problems with the drinking water at a particular moment in time. Clean water can change from year to year, so the only way to know with certainty that your drinking water is safe is to have it tested regularly. It’s recommended to test a private well at least once per year, however, if there is any flooding in the area that could cause the well to fill with contaminated surface water, then you may need to test and take action.  Additionally, if you replace or repair any parts of the well system or if you notice any changes in taste, color, or odor, then it’s a good idea to have the well water tested to make sure that there isn’t anything harmful in the water.

The purpose of well testing is to look for any possible contaminants in your drinking water that could negatively impact your health. Common contaminants include E. Coli, coliform bacteria, nitrates, lead, and arsenic which could pose a risk.

  • Nitrate: Commonly found in areas where fertilization practices are common. Can cause serious health concerns for pregnant women & children.
  • Bacteria (Coliform, E. coli): Commonly found in wells and can indicate that other bacteria, viruses, and parasites may be present. Can lead to nausea, diarrhea, and stomach pains.
  • Arsenic: Commonly found in bedrock and soil, but pollution from agriculture and manufacturing can also contain arsenic. Can cause nausea and stomach pain, cancer, and heart disease.
  • Lead: May be found in older homes with lead piping. Especially dangerous for young children because it can slow down their development, impair their hearing, and cause behavioral issues.

During 2022, the Walworth County Public Health Water lab analyzed over 1,700 samples from both drinking water and recreational water. The Private Well Sampling Project was also conducted during July 2022, with a total of 151 well water tests conducted for private residence wells. 4 out of 98 wells had unsafe nitrate levels.   17 out of 101 wells had unsafe bacteria levels.  1 out of 91 had high arsenic levels, and 5 out of 84 wells had high lead levels.   It’s important to test your well water!
