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
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 constituents have been detected. The EPA has determined that your water IS SAFE at these levels.
The sources of drinking water for our system included several groundwater springs in Huntington Canyon. All sources of drinking water are subject to potential
contamination by constituents that are naturally occurring or are manmade. Those contaminants can be microbial, inorganic contaminants, pesticides and herbicides,
organic chemical contaminants, or radioactive contaminants. 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 and potential
health effects can be obtained by calling the Environmental Protection Agency's Safe Drinking Water Hotline at [phone].
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 [phone].
Five (5) lead samples were collected during 2022. Sampling results can be obtained by calling 381-5333 or emailing [e-mail].

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 [e-mail]. 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.
Castle Valley Special Service District works diligently to provide quality water to each tap. We ask that all our customers help us protect our water sources, which are the
heart of our community, our way of life, and our children's future. Please call 381-5333 if you have any questions.
