High Hills Rural Water Company, Inc. 2016 Annual Drinking Water Quality Report SC#4320003 Prepared June 09, 2017 We are pleased to present to you this year's Annual Quality Water Report. This report is designed to inform you about the quality water and services we deliver to you every day. Included are details about where your water comes from, what it contains and how it compares to the Environmental Protection Agency (EPA) and The South Carolina Department of Health and Environmental Control (SCDHEC) standards. Our constant goal is to provide you with a safe and dependable supply of drinking water. We want you to understand the efforts we make to continually improve the water treatment process and protect our water resources. We are committed to ensuring the quality of your water. This Annual Drinking Water Quality Report will provide you with accurate facts and will be distributed to you on an annual basis as required by EPA and SCDHEC. Our sourcewater assessment is available at the SCDHEC website: www.scdhec.gov/HomeAndEnvironment/Water/SourceWaterProtection/mindex.htm. If you do not have internet access, please contact John Loney at (803) 499-4118 to make arrangements to review this document. We want our valued customers to be informed about your water utility company. If you want to learn more, please attend any of our regularly scheduled meetings. The meetings are held on the second Monday of each month at the High Hills Rural Water Company office at 7:00 PM. If you have any questions about this report or concerning the company, Please contact John Loney at (803) 499-4118, Monday through Friday, 8:00AM-5:00PM. WHERE DOES YOUR WATER COME FROM? Your water source is derived from 5 (five) deep water wells which draw from the Black Creek and Upper Tuscaloosa Aquifers. WATER QUALITY As water travels over the land or underground, it can pick up substances or constituents such as microbes, inorganic and organic chemicals, and radioactive substances. All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some contaminants. It's important to remember that the presence of these constituents does not necessarily pose a health risk. High Hills Rural Water Company routinely monitors for constituents in your drinking water according to Federal and State laws. This table shows the results of our monitoring for the period of January 1st to December 31st, 2016. The following list of definitions will be helpful to you in understanding the table of constituents. We’re pleased to report that our drinking water is safe and meets federal and state requirements. DEFINITIONS In this list you will find many terms and abbreviations you might not be familiar with. To help you better understand these terms we've provided the following definitions: Non-Detects (ND) - laboratory analysis indicates that the constituent is not present. Parts per million (ppm) or Milligrams per liter (mg/l) - one part per million corresponds to one minute in two years or a single penny in $10,000. Parts per billion (ppb) or Micrograms per liter - one part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000. Picocuries per liter (pCi/L) - picocuries per liter is a measure of the radioactivity in water. Action Level - the concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow. 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 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 disinfectants to control microbial contaminants. Maximum Contaminant Level - The “Maximum Allowed” (MCL) is 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 - The “Goal” (MCLG) is the level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.

Some people who drink water containing copper in excess of the action level over many years could suffer liver or kidney damage. People with Wilson's disease should consult their personal doctor. WHAT DOES THE ABOVE INFORMATION MEAN? 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. If present, elevated lead levels can cause serous 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. High Hills Rural Water Company 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. If you are concerned about lead in your drinking 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 http:/www.epa.gov/safewater/lead All sources of drinking water are subject to potential contamination by substances that are naturally occurring or man made. These substances can be microbes, inorganic or organic chemicals and radioactive substances. 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 1-800-426-4791. 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 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 1-800-426-4791.
