Water Testing

Includes	Information on test
Total Coliform Bacteria*	Tests if your well is producing bacteriologically free water. This is the most important test to perform regularly on a private water supply.
Nitrate-Nitrogen*	Nitrate is the most common chemical contaminant in Wisconsin groundwater. Sources of nitrate include fertilizers, septic systems or manure and bio-solid applications. This test serves as an indicator of land-use impacts and may indicate the presence of other contaminants such as pesticides.
pH	Measures the relative acidity of water. Useful in assessing the corrosivity of water to plumbing.
Alkalinity	Amount of bicarbonate (acid neutralizing capacity). This test is related to pH and important for determining the corrosivity index.
Total Hardness	Measure of the amount of calcium and magnesium. Important for water softening considerations.
Chloride	Another indicator of overall water quality and land-use impacts. If elevated indicates contamination from septic systems, fertilizers, or road salts.
Conductivity	Measure of total dissolved minerals in water. Changes in conductivity over time may be indicative of contamination from surrounding land-use activities.
Corrosivity Index	This is a calculation to determine whether your water will form scale or be corrosive.
