Town ofOnancock  2022 Annual Drinking Water Quality Report  Introduction  This Annual Drinking' Water Quality Report for the calendar year 2022 is designed toi inform you about your drinking water quality. Our goal is to provide you with a safe and dependable supply of drinking water, and we want you to understand the efforts we make to protect your water supply. The quality ofyour drinking water must meet state and  federal requirements administered by the Virginia Department of Health (VDH).  Ifyou have questions about this report, please contact: Victor Talbot, Water Operator (757)302-9116  Ify you want additional information about any aspect of your drinking water or want to know how to participate in  decisions that may affect the quality ofyour drinking water, please contact:  Town Manager's Office (757)787-3363 How can I get involved?  The times and location of regularly scheduled town council meetings are as follows: Town Hall, 15 North Street: Fourth Monday of each month at 7:00 pm  Spanish (Espanol) - Este informe contiene informacion importante acerca de su agua potable.

The Town of Onançock receives its water from three wells off Hartman Avenue. The source of your water is The Virginia Department of Health conducted a Source Water Assessment of the wells in 2018. The susceptibility toc contamination of the wells was rated as low susceptibility to contamination using the criteria developed by the state ini its approved Source Water Assessment Program. The assessment reports consist ofmaps showing the Source Water Assessment area, an inventory of known Land Use Activities and Potential Conduits to Groundwater utilized at Land Use Activity sites in Zone 1 and documentation of any known contamination within the last five years, Susceptibility Explanation Chart, and Definitions of Key Terms. The reports are available by contacting your  groundwater.  Source water assessment and availability  waterworks system owner/operator at the phone number or address included in the CCR.  Isn my water safe?  In2 2022, your water met all U.S. Environmental Protection Agency (EPA) and state drinking water health standards. The Town vigilantly safeguards its water supplies and we are proud to report that our system has not violated a  maximum contaminant level or any other water quality standard.  DoIneed to take special precautions?  Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno- compromised persons such as person 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/Center for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (800-426-  4791).  Water Quality Data Table:  1    For the benefit of people who are restricting their sodium intake, lab testing indicates a sodium level of24.7 ppm. A "severely restricted" sodium diet allows consumption of water with 20 ppm sodium, and a "low" sodium diet allows 270 ppm. For questions or concerns about sodium intake and your tap water, contact your The table below lists all of the drinking water contaminants that we detected during the calendar year oft this report. Many other contaminants were analyzed, but not detected. The presence of contaminants in the water supply does not necessarily indicate that the water poses a health risk. Unless otherwise noted, the data presented in this table is from testing done in the calendar year of the report. The EPA or the state requires us to monitor for certain contaminants less than once per year because the concentrations oft these contaminants do not change frequently.  doctor.

LVL2 - Level 2 Assessment under the RTCR - A Level 2 assessment is a very detailed study ofthe waterworks to identify potential problems and determine, if possible, why an E. coli PMCL violation has occurred and why  total coliform bacteria have been found in our waterworks on multiple occasions.  Why are there contaminants in my drinking water ?  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 water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection As water travels over the surface oft the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive materials, and can pick up substances resulting from the presence of animals or from human microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic inorganic contaminants, such as salts and metals, which can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming; pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater organic chemical contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining In order to ensure that tap water is safe to drink, EPA prescribes regulations that limit the amount of certain contaminants in water provided by public water systems. Food and Drug Administration (FDA)regulations establish If present, elevated levels of 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. The Town of Onançock is responsible for providing high quality drinking water but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes or until it becomes cold or reaches a steady temperature before using water for drinking or cooking. Ifyou are conçerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline (800-426-4791) or online at  Agency's Safe Drinking Water Hotline (800-426-4791).  activity. Contaminants that may be present in source water include: systems, agricultural livestock operations, and wildlife;  runoff, and residential uses; septic systems; activities.  limits for contaminants in bottled water that must provide the same protection for public health.  Additional information on Lead  PpgPsNas Conservation Tips  Did you know that the average U.S. household uses approximately 350 gallons of water per day? Luckily, there are many low-cost or no-cost ways to conserve water. Water your lawn at the least sunny times of the day. Fix toilet and faucet leaks. Take short showers - a 5-minute shower uses 20 gallons of water compared to 50 gallons fora a bath. Turn the faucet off while brushing your teeth and shaving; 3 - 5 gallons go down the drain per minute. Teach your kids about water conservation to ensure: at future generation uses water wisely. Make it a family effort to reduce  your next water bill!! Victor Talbot Townof Onancock (757)-302-9116  For more information, please contact: 15North Street. Onancock. Virginia 23417  3    4
