North Texas Municipal Water District - Bonham Water Treatment Plant
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.
