Chlorine N 1.16 ppm 4 4 2024 Synthetic Organic Contaminants including Pesticides and Herbicides (every 3 years) During 2022 the water was tested for 26 groups of Pesticides and Herbicides. None were detected in any of the samples. Volatile Organic Contaminants (every 3 years) During 2024 the water was tested for 57 different Volatile Organic Contaminants. None were detected in any of the samples. As you can see by the table, our system had no violations. We're proud that your drinking water meets or exceeds all Federal and State requirements. We have learned through our monitoring and testing that some contaminants have been detected. The EPA has determined that your water IS SAFE at these levels. All sources of drinking water are subject to potential contamination by contaminants that are naturally occurring or are manmade. Those contaminants can be microbes, organic chemical contaminants, inorganic contaminants, or radioactive materials. All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that the water poses a health risk. More information about contaminants are potential health effects can be obtained by calling the Environmental Protection Agency's Safe Drinking Water Hotline at (800) 426-4791. MCL's are set at very stringent levels. To understand the possible health effects described for many regulated constituents, a person would have to drink 2 liters of water every day at the MCL level for a lifetime to have a one-in-a-million chance of having the described health effect. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by cryptosporidium and other microbiological contaminants are available from the Safe Drinking Water Hotline at (800) 426-4791. Ten (10) lead samples were collected during 2022. Sampling results can be obtained by calling 381-5333 or emailing cvssd877@etv.net. 2024 WATER QUALITY TEST RESULTS CASTLE DALE (PWS #08001) Likely Source of Contamination Microbiological Contaminants Naturally present in the environment Human and animal fecal waste Soil Runoff (highest single measurement & the lowest monthly percentage of samples meeting the turbidity limits) Radioactive Contaminants Erosion of natural deposits Erosion of natural deposits Inorganic contaminants Erosion of natural deposits; runoff from orchards; runoff from glass and electronics production wastes Decay of asbestos cement water mains; erosion of natural deposits Discharge of drilling wastes; discharge from metal refineries; erosion of natural deposits Corrosion of household plumbing systems; erosion of natural deposits Discharge from steel/metal factories; discharge from plastic and fertilizer factories Erosion of natural deposits; water additive which promotes strong teeth; discharge from fertilizer and aluminum factories Corrosion of household plumbing systems, erosion of natural deposits Erosion of natural deposits; discharge from refineries and factories; runoff from landfills; runoff from cropland Runoff from fertilizer use; leaching from septic tanks, sewage; erosion of natural deposits Discharge from petroleum and metal refineries; erosion of natural deposits; discharge from mines Erosion of natural deposits; discharge from refineries and factories; runoff from landfills Erosion of natural deposits; discharge from refineries and factories; runoff from landfills, runoff from crops Erosion of natural deposits By-product of drinking water disinfection By-product of drinking water disinfection Water additive used to control microbes Synthetic Organic Contaminants including Pesticides and Herbicides (every 3 years) During 2022 the water was tested for 26 groups of Pesticides and Herbicides.

Lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. Castle Valley Special Service District is responsible for providing high quality drinking water and removing lead pipes, but cannot control the variety of materials used in plumbing components in your home. You share the responsibility for protecting yourself and your family from the lead in your home plumbing. You can take responsibility by identifying and removing lead materials within your home plumbing and taking steps to reduce your family's risk. Before drinking tap water, flush your pipes for several minutes by running your tap, taking a shower, doing laundry or a load of dishes. You can also use a filter certified by an American National Standards Institute accredited certifier to reduce lead in drinking water. If you are concerned about lead in your water and wish to have your water tested, contact Castle Valley Special Service District at 381-5333 or cvssd877@etv.net. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available at http://www.epa.gov/safewater/lead.
