Have someone translate iti for you, or speak with someone who understands it.) This report shows our water quality and what it means. If you have any questions about this report or concerning your water utility, please contact Barbara Henry at 717-274-3436. We want you to be informed about your water supply. If you want to learn more, please attend any of our regularly scheduled meetings. The Water/Sewer Committee meetings are held the first Monday of each month at 9:00a.m. The Borough meetings are held the second Monday of each month at 6:30 p.m. in the Borough Office located at 44 WATER SYSTEMINFORMATON. Rexmont Road. SOURCE(S) OF WATER: www.comwal-pa.com. Cornwall Borough receives its water from the City of Lebanon Authority (COLA) surface water source. The COLA: 2023 CCR report is on the Borough website or attached for your reference. Cornwall's website is 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 who have undergone organ transplants, people with HIVIAIDS 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 microbial contaminants are available from the Safe Drinking Water Hotline 800-426-4791). MONITORING YOUR WATER: We routinely monitor for contaminants in your drinking water according to federal and state laws. The following tables show the results of our monitoring for the period of January 1t to December 31, 2023. The State allows us to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently. Some of our data is from prior years in accordance with the Safe Drinking Water Act. The date has been noted on the sampling results table. DEFINITIONS: Action Level (AL) - The concentration of a contaminant which, if exceeded, triggers treatment or other Maximum Contaminant Level (MCL) - The highest level of a contaminant that is allowed in drinking water. MCLS are set as close to the MCLGS as feasible using the best available treatment technology. Maximum Contaminant Level Goal (MCLG)- - The level of a contaminant in drinking water below which there Maximum Residual Disinfectant Level (MRDL) - The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial requirements which a water system must follow. is no known or expected risk to health. MCLGS allow for a margin of safety. contaminants. Maximum Residual Disinfectant Level Goal (MRDLG) - The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGS do not reflect the benefits of the use of Minimum Residual Disinfectant Level (MinRDL) - The minimum level of residual disinfectant required at the disinfectants to control microbial contaminants. entry point to the distribution system. ppm = parts per million, or milligrams per liter (mg/L) ppb = parts per billion, or micrograms per liter (ug/L) DETECTED SAMPLE RESULTS: Chemical Contaminants MCL in CCR MRDL= MRDLG 4 80 60 Level 1.11 40.6 24.1 Range of 0.22-1.95 19.0-64.6 ppb 12.9-36.5 ppb Sample Violation 2023 2023 2023 Sources of Contamination Water additive used to control microbes.

EDUCATIONAL INFORMATION: The 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 of the 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 Microbial contaminants, such as viruses and bacteria, may come from sewage treatment plants, Inorganic contaminants, such as salts and metals, can be naturally occurring or result from urban stormwater run-off, industrial or domestic wastewater discharges, oil and gas production, mining, or Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban from human activity. Contaminants that may be present in source water include: septic systems, agricultural livestock operations, and wildlife. farming. stormwater runoff, and residential uses. urban stormwater runoff, and septic systems. Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by- products of industrial processes and petroleum production, and can also come from gas stations, Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities. In order to ensure that tap water is safe to drink, EPA and DEP prescribe regulations which limit the amount of certain contaminants in water provided by public water systems. FDA and DEP regulations establish limits for contaminants in bottled water which must provide the same protection for public health. 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 Agency's Safe Drinking Water Hotline (800-426-4791). Information about Lead Ifp 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. Cornwall Borough 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 before using water for drinking or cooking. Ify you are concerned 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 or at ntp/www.epa.gvVsalewaterlead. OTHER INFORMATION: The Borough staff endeavors to investigate any issue that may arise at your home or business. If you have a problem or see something you think may be a potential problem = i.e. Water lying in the street, please give us a call at 717-274-3436.
