2023. Annual Drinking Water Quality Report  Pamlico County Water Water System Number: NC 04-69-025  We are pleased to present to, you this year's Annual Drinking Water Quality Report. This report is a snapshot of last year's water quality. Included are details about yours source(s) of water, what it contains, and how it compares to: standards set by regulatory agencies. Our constant goal is to provide you with a: safe and dependable supply of drinking water. We want you to understand the efforts wei make to continually improve the water treatment process and protect our water resources. We are committed to ensuring the quality of your water and toj providing you with this information because informed customers are our best allies. Ifyou have any questions about this report or concerning your water, please contact Jeff Sanders at 9252) 745-5453. We want our valued customers to bei informed about their water utility. Ifyou want to learn more, please attend any of our regularly scheduled meetings. They are held at County Court House on the first and third Monday ofe each month at 7:00 pm.  What EPA Wants You to Know  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 al health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency's Safe Drinking Water Hotline (800-426- Some people may be more vulnerable to contaminants in drinking water than the general population. mmuno-compromised persons such as persons with cancer undergoing chemotherapy, persons whol 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 tol lessen the risk of infection by Cyptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791). Ifpresent, 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. Pamlico County Water is responsible for providing high quality drinking water, but cannot control the variety ofi materials used inj plumbing components. When your water has been sitting fors several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 21 minutes before using water for drinking or cooking. Ifyou are concerned about leadi in your water, you may wish tol have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over thes surface of thel 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 bej present in source water include microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife; inorganic contaminants, such as salts and metals, which can bei 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 ofs sources such as agriculture, urban stormwater runoff, and residential uses; organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products ofi industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems; and radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining Ino order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. FDA regulations establish limits for contaminants in bottled water, which must provide the same  4791).  isa available from the Safe Drinking Water Hotline or at tp/www.epa.govsafewaterlead.  activities.  protection for public health.  When You Turn on Your Tap, Consider the Source  The water that is used by this system is groundwater wells located throughout the County.  12/2023    Source Water Assessment Program (SWAP) Results  Thel North Carolina Department of Environmental Quality (DEQ), Public Water Supply (PWS) Section, Source Water Assessment Program (SWAP) conducted assessments for all drinking water sources across North Carolina. Thej purpose oft the assessments was to determine the susceptibility of each drinking waters source (well or surface water intake) to Potential Contaminant Sources (PCSs). The results of the assessment are available in SWAP Assessment Reports that include maps, background information and a relative The relative susceptibility rating ofe each source for Pamlico County Water was determined by combining the contaminant conditions of the well or watershed and its delineated assessment area). The assessment findings are summarized in the table below:  susceptibility rating of Higher, Moderate or Lower.  location  rating  (number and  of PCSs within thea assessment area) and the inherent vulnerability rating (i.e., characteristics or existing  Susceptibility of Sources tol Potential Contaminant Sources (PCSs)  Source, Name Milll Pond Well# #1 Mill Pond Well#2 Vandemere Well #1 Vandemere Well#2 Grantsboro Well#1 Grantsboro Well#2 Kershaw Well #1 Kershaw Well#2  Susceptibility Rating Lower Lower Lower Lower Lower Lower Lower Lower  SWAP Report Date September 10, 2020 September 10, 2020 September 10, 2020 September 10, 2020 September 10, 2020 September 10, 2020 September 10, 2020 September 10, 2020  The complete SWAP Assessment report for Pamlico County Water may be viewed on the Web at:  MNEANeEN Note that because SWAPI results and reports are periodically updated by the PWS Section, the results available on this web site may differ from the results that were available at the time this CCR was prepared. Ifyoua are unable to access your SWAPI report on the web, you may mail a written request for aj printed copy to: Source Water Assessment Program - Report Request, 16341 Mail Service Center, Raleigh, NC 27699-1634, or email requests tos swap@nedenr.gov. Please indicate your system name, number, and provide your name, mailing address andj phone number. Ifyoul have any questions about the SWAP  report please contact the Source Water Assessment staff by phone at 919-707-9098.  Itis important to understand that a susceptibility rating of "higher" doesnot imply poor water quality, only the system's potential to  become contaminated by PCSs in the assessment area. Help Protect Your Source Water  Protection of drinking water is everyone's responsibility. We have implemented the following source water protection actions: You can help protect your community's drinking waters source(s) in several ways: (examples: dispose of chemicals properly; take used motor oil to a recycling center, volunteer iny your community to participate in group efforts toj protect your source, etc.).

Water Quality Data Tables of Detected Contaminants  Wer routinely monitor for over 150 contaminants in your drinking water according tol Federal and State laws. The tables below list all the drinking water contaminants that we detected in the last round of sampling for eachj particular contaminant group. Thej ofcontaminants does not necessarily indicate that water poses al health risk. Unless otherwise noted, the data presented in presence this table is from testing done January 1 through December. 31, 2023. The EPA and the State allow us to monitor for certain contaminants less than once per year because the concentrations of these contaminants are not expected to vary significantly from  year to year. Some of the data, though representative of the water quality, is more than one year old.
