What does water hardness mean?
As water naturally flows over rocks and through the soil, it picks up minerals that get dissolved in the water. The more calcium and magnesium present, the harder your water. While water hardness is not a safety issue, you may notice increased mineral build-up or soap residue with harder water. Water hardness can be expressed as PPM – parts per million or GPG – grains per gallon.
Because the hardness of water is a result of the different minerals in the rocks and soil, water hardness does vary by source.
What is your primary source of drinking water?
You can find the hardness for your primary source for drinking water by looking on our Authority GIS .
- Click on the Authority GIS link to open the GIS
- The SEARCH tool box will open with the mapping. Type in your house number and street name (do not put Road, Drive, Lane, etc.)
- Your property will appear on the screen highlighted in yellow.
- Click on the Detail Identify icon (the i symbol in the blue circle) located above the mapping
When the pop-up box appears, use the drop-down arrow next to the word Parcels to scroll down to the very last one on the list called HGL (it stands for Hydrallic Grade Line)
- Click on HGL
- Click on your highlighted property
- Your primary source of drinking water will appear in the pop-up box. Please note that your water source may vary depending on changes in the distribution system and water plant production.
