Silver

East Lyme Water & Sewer Commission

NOTE: East Lyme Water & Sewer Commission purchases water from New London Department of Public Utilities which is required to test for silver. Sample information shown below was taken by New London Department of Public Utilities.

Silver occurs naturally in surface and groundwater and can be added to water as a biocide that inhibits growth of bacteria and algae. Increasingly, the use of antimicrobial nano-sized silver particles in consumer products contributes to silver in water sources used for drinking water.
