The Langelier Index is required by the Township of Mendham for a Certificate of Potability for home resale.  It is an approximate indicator of the degree of saturation of calcium carbonate in water.  It is calculated (58 KB) using the pH, alkalinity, calcium concentration, total dissolved solids and water temperature of a water sample collected at the tap.

Certificates of Continued Use and Well Potability are to be issued by the Township Health Department.
