WATER SYSTEM: INFORMATION: We're pleased to present to you this year's Annual Drinking Water Quality Report. This report is designed to inform you about the quality water and services we deliver to you every day. Our constant goal is to provide you with a 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 We are pleased to report that our drinking water meets federal and state requirements. If you have any questions about this report or concerning your  water.  water utility, please contact the Borough Office at 610-562-7821. We want our valued customers to be informed about their water utility. Ify you would like to learn more, please attend any of our regularly scheduled meetings. They are held on the third Wednesday of each month at 7:00F P.M. at the Hamburg Municipal Center  located at 61 North Third Street. SOURCES OF WATER:  Our water sources are thel Furnace Creek Reservoir, Wells 2,3,4,6, &7 located at the Furnace Creek Filtration Plant on Reservoir Road and Well 5 which is located at Upland Court, all of which are located in Windsor Township. The main storage tank has a finished water capacity of1.154 million gallons. This contains at least  an entire day supply of water in reserve. MONITORING YOUR WATER:  The Hamburg Municipal Authority routinely monitors for contaminants in your drinking water according to Federal and State laws. The following table shows the results of our monitoring for the period of January 1, 2021 to December 31, 2021. All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some constituents. It's important to remember that the presence of these Thank you for allowing us to continue providing your family with clean, quality water this year. In order to maintain a dependable water supply, we sometimes need to make improvements that will benefit all of our customers. These improvements are often reflected as rate structure adjustments. Thank you for understanding.  constituents does not necessarily pose al health risk.  DEFINITIONS AND ABBREVIATIONS: years or a single penny in $10,000. or a single penny in $10,000,000.

Note: In addition to the contaminants listed in the chart above, the Hamburg Municipal Authority routinely tests for numerous contaminants, which were not detected. Water samples are tested monthly for bacteria, as well as quarterly for several Volatile Organic Contaminants (VOC's) and annually for several Inorganic Contaminants The Pennsylvania Department of Environmental Protection (DEP) detected five (5) observations in 2021 for the Hamburg Municipal Authority water system. These were attributed to late reporting. These observations did Hamburg's water supply comes from reservoirs and wells. As water travels over the land surface 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 be present in Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, Inorganic contaminants, such as salts and metals, which can be naturally-occuring or result from  No single sample may exceed 2.0NTU.

We are pleased to report the latest sampling did not detect any lead in your drinking water. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. Hamburg Municipal Authority 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. Ifyou are concerned about lead in your water, you may with to have your water tested. Information on lead in drinking water, testing methods, and steps you can take toi minimize exposure is available 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 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. MCL's are set at very stringent levels for health effects. To understand the possible health effects described for many regulated constituents, aj person would have to drink 2 liters of water every day at thel MCL level fora al lifetime to have a one-in-a-million chance of 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 othern microbiological contaminants are available from the Safe Drinking Water Hotline (800-426-4791).
