About Us
Municipal water sources include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over land surfaces or through soil, it dissolves naturally-occurring minerals and, in some cases, radioactive materials, and can absorb substances from animal or human activities.
Potential contaminants in source water include:
- Microbial contaminants: Viruses and bacteria from sewage treatment plants, septic systems, agricultural operations, and wildlife.
- Inorganic contaminants: Salts and metals that occur naturally or result from urban stormwater runoff, industrial/domestic wastewater discharges, oil/gas production, farming, or mining.
- Pesticides and herbicides: From various sources including agriculture, urban stormwater runoff, and residential uses.
- Organic chemical contaminants: Including synthetic and volatile organic compounds from industrial processes, petroleum production, gas stations, urban stormwater runoff, and septic systems.
- Radioactive contaminants: Naturally-occurring or resulting from oil/gas production and mining activities.
