As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive materiaL and can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water include: • Microbial comaminams,such as viruses and bacteria,that may come from sewage treatment plants,septic systems,agricultural livestock operations,and wildlife. • Inorganic contaminants, such as salts and metals, that can be naturally-occurring or result from urban stormwater rano$ industrial or domestic wastewater discharges,oil and gas production,mining,or farming. 2018 SWS CCR Form Revised Feb 2019
