Water "hardness" is a measure of the mineral content in your tap water. Minerals such as calcium and manganese are prevalent in the groundwater sources of the Lehigh Valley. While these minerals are essential to human health, some customers prefer to "soften" the water by installing a water softener. Most softeners work by replacing the minerals with sodium, which may be a health concern for some people. Therefore, water softening is an individual choice made by each customer.
How hard is your water?
Hardness is measured in Parts Per Million (ppm) or Grains Per Gallon (gr/gal) and can fall anywhere in the following scale:
Soft Water ............ 0-75 ppm or 0-4.4 gr/gal
Moderate Water .... 75-150 ppm or 4.4-8.8 gr/gal
Hard Water ........... 150-300 ppm or 8.8-17.5 gr/gal
Very Hard Water ... 300+ pmm or 17.4+ gr/gal
