2018. Annual Drinking Water Quality Report  Town of Parmele Water System Number: NC04-59-113  We are pleased to present toy yout this year's Annual Drinking Water Quality Report. This report isas snapshot ofl last year's water quality. Included are details about yours source(s) ofwater, what it contains, and how it compares tos standards set by regulatory agencies. Our constant goal ist top provide you with a safe and dependable supply of drinking water. We want yout to understand the efforts we make to continually improve the water treatment process andj protect our water resources. We are committed to ensuring the quality ofyour water andt toj providing: you with this information because informed customers are our best allies. If you have any questions about this report or concerning your water, please contact the Robersonville Town) Hall at (252) 508-0311. Wer want our valued customers tol bei informed about their water utility. Ifyou want tol learn more, please attend any of our regularly scheduled meetings. The regularly scheduled meetings arel held on the first Tuesday ofe each  month at' 7:00 PM: at thel Parmele Town Hall. What EPA Wants You to Know  Drinking water, including bottled water, may reasonably be expected to contain at least small amounts ofs some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. Morei information about contaminants and potential health effects can be obtained by calling thel 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. 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 bep 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 ofinfection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (800- Ifpresent, elevated levels ofl lead can cause serious health problems, especially for pregnant women and young children. Leadi in drinking water is primarily from materials and components associated with service lines and home plumbing. The Town of Parmele is responsible for providing high quality drinking water, but cannot control the variety of materials usedi in plumbing components. When your water has beens sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30: seconds to 2 minutes before using water for drinking or cooking. Ifyou are concerned about lead in your water, you may wisht tol have your water tested. Information on leadi in drinking water, testing methods, ands steps you can take to minimize exposure is available from the Safel Drinking Water Hotline or at! htp/vww.epagovisafewater/lead. Thes sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the: surface oft thel land or through the ground, it dissolves naturally-occurring: minerals and, in some cases, radioactive material, and can pick up: substances resulting fromt the presence ofanimals or froml human activity. Contaminants that may be present in source wateri 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 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 runoff, and residential uses; organic chemical contaminants, including synthetic and volatile organic chemicals, which arel by-products ofi industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, ands septic systems; and radioactive contaminants, which can be naturally-ocuring or be the result ofo oil and In 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  4791).  426-4791).  gas production and mining activities. the same protection for publicl health.  When You Turn on Your' Tap, Consider the Source  The water thati is used by the Town of Parmele is purchased from the Town ofl Robersonville andi is ground water from 7 wells  located ini the Black Creek Aquifer. 2018 Annual CCR    Source Water Assessment Program (SWAP) Results  Thel North Carolina Department ofl Environment and! Natural Resources (DENR), Public Water Supply (PWS) Section, Source Water Assessment Program (SWAP) conducted. assessments for all drinking water sources across North Carolina. The purpose of the assessments was to determine the: susceptibility ofeach drinking water source (well or surface water intake) tol Potential Contaminant Sources (PCSs). The results of the assessment are available in SWAP. Assessment Reports that include maps, Ther relative susceptibility rating of cach source: for' Town of Parmele was determined by combining the contaminant rating (number and location of PCSs within the assessment area); and the inherent vulnerability rating (i.e., characteristics ors existing conditions oft the well or watershed andi its delineated assessment area).

Violations that Your Water System Received for thel Report Year We are pleased to report thatt there were no violations during the 2018 compliance period. Water Quality Data Tables of Detected Contaminants  Wer routinely monitor for over 150 contaminants in your drinking water according tol Federal and Statel laws. The tables below list all the drinking water contaminants that we detected in the last round ofs sampling for each particular contaminant group. The presence of contaminants does not necessarily indicate that water poses a health risk. Unless otherwise noted, the data presented in this tablei is from testing done. January 1 through December 31, 2018. The EPA and the State allow us to monitor for certain contaminants less than oncep per year because the concentrations oft these contaminants are not expected to vary significantly from Unregulated contaminants are those for which EPAI has not established drinking water standards. The purpose ofunregulated contaminant monitoring ist to assist] EPA in determining the occurrence of unregulated contaminants in drinking water and whether  year to year. Some oft the data, though representative ofthe water quality, is more than one, year old.  future regulations are warranted.
