CONTAINMENTS I WATER III <br />MAIN SOURCE WATER <br />CONTAMINANTS <br />Microbial contaminants, such as viruses, <br />bacteria, and parasites. Sources include sewage <br />treatment plants, septic systems, agricultural <br />livestock operations, pets, and wildlife. <br />Inorganic contaminants include salts and metals <br />from natural sources (e.g. rock and soil), oil and <br />gas production, mining and farming operations, <br />urban stormwater runoff, and wastewater <br />discharges. <br />Pesticides and herbicides are chemicals used to <br />reduce or kill unwanted plants and pests. Sources <br />include agriculture, urban stormwater runoff, and <br />commercial and residential properties. <br />Organic chemical contaminants include <br />synthetic and volatile organic compounds. Sources <br />include industrial processes and petroleum <br />production, gas stations, urban stormwater runoff, <br />and septic systems. <br />Radioactive contaminants such as radium, <br />thorium, and uranium isotopes come from natural <br />sources (e.g. radon gas from soils and rock), <br />mining operations, and oil and gas production. <br />SPRWS SOURCE <br />WATER ASSESSMENT <br />The Minnesota Department of Health provides information <br />about your drinking water source(s) in a source water <br />assessment, including: <br />How Saint Paul Regional Water Services is <br />protecting your drinking water source(s), <br />Nearby threats to your drinking water sources, <br />How easily water and pollution can move from the <br />surface of the land into drinking water sources, <br />based on natural geology and the way wells are <br />constructed. <br />Find your source water assessment at Source Water <br />Assessments: Call651-201-4700 or1-800-818-9318 <br />between 8:00 a.m. and 4:30 p. m., Monday through Friday <br />or go to tinyurl.com/y4xmkk5a. <br />ARE YOU MORE VULNERABLE TO CONTAMINANTS? <br />Some people may be more <br />vulnerable to contaminants in <br />drinking water than the general <br />population. I mmunocompromised <br />persons such as persons <br />with cancer undergoing <br />chemotherapy, persons <br />who have undergone organ <br />transplants, people with HIV/ <br />AIDS or other immune system <br />disorders, some elderly, and <br />infants can be particularly at risk <br />from infections. The developing <br />fetus and therefore pregnant <br />women may also be more <br />vulnerable to contaminants in <br />drinking water. These people <br />or their caregivers should seek <br />advice about drinking water from <br />their health care providers. EPA/ <br />Centers for Disease Control <br />(CDC) guidelines on appropriate <br />means to lessen the risk of <br />infection by Cryptosporidium and <br />other microbial contaminants are <br />available from the Safe Drinking <br />Water Hotline at 1-800-426-4791. <br />Page 39 of 76 <br />
