The Hollidaysburg Borough Authority is pleased to present to you this year's "Quality on Tap", I Hollidaysburg Borough Authority Water Quality Report fori the 2023 Report Year. This report has been prepared in accordance with the US Environmental Protection Agency and the PA Department of Environmental Protection guidelines and is designed to inform you about the quality of 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 to protect our water resources. We are committed to ensuring the quality of your water. The Hollidaysburg Borough Authority had 1 monitoring violation for 2023. On 09/11/23 the lab failed to submit all of the routine check samples for the RTCR. The missing samples have been submitted. On 09/01/23 AWA had a routine monitoring violation for the RTCR. On 10/01/23, AWA had a Failure to Monitor violation for Haloacetic Acids HAA5. Compliance was achieved for this violation. OUR WATER SYSTEM The Hollidaysburg water system is a consecutive system of the Altoona Water Authority (AWA) water system, which means we purchase our treated water from the AWA for distribution to our customers in the Hollidaysburg Borough Authority (HBA) system. The primary source of supply for the water provided to the Hollidaysburg Borough Authority originates from two surface water reservoirs, the Muleshoe Reservoir, which is owned by the HBA, and the Plane Nine Reservoir, which is owned and operated by the AWA, Both reservoirs are located on Cresson Mountain in Junlata Township, Blair County. The Plane Nine Reservoir is situated along the south side of Old Rt. 22, approximately 3 miles west of Duncansville. The Muleshoe Reservoir is located upstream from the Plane Nine Reservoir, in a forest area approximately % mile south of Old Rt. 22, just past the Muleshoe overpass of Old Rt. 22. Raw (untreated) water is drawn from both reservoirs and is blended, filtered and treated at the AWA Plane Nine Filtration Plant, The Plane Nine Plant is located immediately below the Plane Nine Reservoir. The treated water is then pumped into the transmission system for distribution to, and consumption by, both the customers of the AWA system and the HBAS system. Water entering the Plane Nine Treatment Plant is first treated with ozone to destroy bacteria and other organisms and to reduce other organic materials that naturally occur in water. The water is then passed through sand filters to remove sediment and other particles. The filtered wateri is then treated with a corrosion inhibitor to reduce its abilityt to react with the water distribution pipes and customers' plumbing systems. Finally, chlorine is applied to the water to provide disinfection of the water during its travels through the distribution system and into our customer's plumbing systems. Because the HBA water system is Inter-connected to the AWA water distribution system, water is also available, during times of emergency and drought, from the many sources of the AWA, including several other surface water reservoirs within the AWA: system. Since there is a potential for water to be provided to the HBA system from these alternative sources and since water may potentially pass through the interconnection, results of analysis conducted on these other sources of supply, have also been included in this report.

The assessment has found that the intakes are potentially most susceptible to transportation corridor (hiway) contaminants and llegal dumping, while a minor susceptibility exists for contamination from natural gas pipelines, public use, abandoned mine land and natural gas wells within the respective watershed areas. A summary of the report is available on the DEP website at www.depstate.paus (Keyword: DEP source water). Copies of the complete report are also available from the Southcentral Regional Office, Records Management Unit at (717) 705-4732. 2023 WATER QUALITY TABLE The HBA and the AWA routinely monitor, and test, for contaminants in your drinking water according to Federal and State laws. The following table shows the results of monitoring conducted by either HBA or the AWA for the period of January 1st to December 31st, 2023 and show results for every regulated contaminant detected in the water, even In the most minute traces. Some of the data in the table may be from test results obtained from prior years, in accordance with the Safe Drinking Water Act, and these dates are noted on the table where applicable, Concentrations of such contaminants do not change frequently in the source water and annual monitoring in not necessary to safeguard the quality of water. The table also contains the nature of each substance, the highest level allowed by regulation, the ideal goals for public health and the amount detected and the usual sources of contamination. In this table you will find many terms and abbreviations you might not be familiar with. Please refer to the Glossary to help you better understand these terms and abbreviations. It should also be noted that additional contaminants have been tested for during 2023 which were not detected to be present in the water.

Quality on Tap June 2024 Page 4 WATER QUALITY AND HEALTH RELATED NFORMATION The Hollldaysburg Borough. Authority routinely monitors for constituents in your drinking water according to Federal and State laws. In order to ensure that tap water is safe to drink, the Unlted States Environmental Protection Agency (EPA) and Pennsylvanla Department of Environmental Protection (DEP) prescribe regulations which limit the amount of contaminants in water provided by public systems. These agencies require monitoring of the water to ensure that your drinking water does not exceed certaln Maximum Contaminant Levels (MCL's). These MCL's are: set at very: stringent levels for the protection of public health. All: sources of drinking water are subject to potential contamlnants that are naturally occurring or man-made. Those contaminants can be microbes, organic or inorganlc chemicals, or radioactive materlals. Drinking water, including bottled drinking water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of these contaminants does not necessarily indicate that the water poses a health risk. More information about contaminants and potential heaith effects can be obtained by calling the Environmental Protection Agency's Safe Drinking Water Hotline at 1- 800-426-4791. The sources of drinking water, Including both tap and bottied water, include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the: surface of the land or through the ground, it dissoives naturally occurring minerals and radioactive material, and can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water Include: > Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural operations and wldlife, > Inorganic contaminants, such as salts and metals, which can be naturally occurring or result from urban 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, stormwater runoff and residential uses. > Organic chemical contaminants, including synthetic and volatile organics, which are by-products of Industrial processes and petroleum production and can also come from gas stations, urban stormwater runoff and septic systems. - Radioactive contaminanis, which can be nalura ally uccurring or be the resuit of oil and gas production and mining activities. Potential Health Effects of Various Contaminants Turbidity: Interferes with disinfection. May provide a medium for microbial growth. May indicate a presence of disease causing organisms. Barium: Some people who drink water containing barlum in excess of the MCL over many years, could experience an increase In blood pressure. Copper: Some people who drink water containing copper in excess of the Action Level may cause gastrointestinal distress over the short term and liver or kidney damago cver a period of many years. Fluoride: Some people who drink water containing fluoride in excess of the MCL over many' years could get bone disease and pain and tenderness of the bones. In children, excess fluoride may cause mottling of the teeth. Lead: Adults who drink water containing lead in excess of the Action Level could develop kidney and high blood pressure problems, Children who drink water contalning lead in excess of the Action Level could experience delays in physical and mental development. Nitrate: Infants below the age of 6 months who drink water containing nitrate In excess of the MCL could become serlously Ill and, If untreated, may die. Symptoms may include shortness of breath, and blue baby syndrome, Chlorine: Some people who use water containing chlorine well in excess of the MRDL could experience irritating effects to their eyes, nose and could experience stomach discomfort. Trihalomethanes & Halogenated Acetic Acids: Some people who drink water containing these contaminants in excess of the MCL over many years maye experience problems with their liver, kidneys or central nervous systems, and may have an increased risk of getting cancer. Some people may be more vuinerable to contaminants In drinking water than the general population. Immuno-compromised persons such as those 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 thelr health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbiological contaminants are avallable from the Safe Drinking Water Hotline at 1-800-426- 4791. Cryptosporidlum are microbial pathogens found in surface water throughout the U.S. The. Altoona Water Authority began testing for E-Coll & Cryptosporidium In late 2015 to comply with the LT2 Enhanced Surface Water Treatment Rule. All results have been within normal, expected ranges. LT2 Testing for all sources was compieted n February 2018, DEP also conducts Filter Piant Performance Evaluations at AWA's facilitles on a regular basis and has never found cryptosporidium In the finished water. Quality on Tap. June 2024 Page 5 GLOSSARY The following are definitions of terms and abbrevlations used throughout this report and in the Water Quallty Tables, AWA - Altoona Water Authority AL - Action Level. The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water: system must follow. CDC- United States Center for Disease Control DEP. - Pennsylvanla Department of Environmental Protection Flocculate - Water treatment process whereby fine sediment and other particles are gathered together to form larger particles in order to improve the ablity of the water flltration process to remove the particles. HBA - Hollidaysburg Borough. Authority MCL- - Maximum Contaminant Level. The highest level of a contaminant that Is allowed in drinking water. MCL's are set as close to the MCLG's as feasible using the best available treatment technology. MCLG - Maximum Contaminant Levei Goal. The level of a contaminant in drinking water below where there is no known or expected risk to health. MCLG's allow for a margin of safety. MRDL - Maximum Residual Disinfectant Level. 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. MRDLG - The level of a drinking water dIsinfectant below which there is no known or expected risk to health. MRDLG's do not reflect the benefits of the use of disinfectants to control microbial contamination. Mrem/yr - Millirems per year. Measure of radiation absorbed by the body. N/A - Not Applicable. ND - Non-Detects. Laboratory analysis indicates that the contaminant is not present at a detectable level. NTU - Nephelometric Turbidity Unit. Nephelometric Turbidlty Unit Is a measure of the clarity of water. Turbidity In excess of 5 NTU is just noticeable to the average person. ppm - Parts per million or millagrams per liter (mg/i). One part per miilion corresponds to one minute in IWO years or a: singie penny in $10,000. ppb - Parts per billion or micrograms per liter. One part per billion corresponds to one minute In 2,000 years, or a single penny in $10,000,000. Treatment Technique - A required process intended to reduce the level of contaminant in drinking water, Turbidity - The measurement of cloudiness of the water. We monitor turbidity because it is a good indicator of the effectiveness of filtration. PLEASE PROTECT... We at the Hollidaysburg Borough. Authority water: system continuously strive to provide top water quality to every tap. We ask that all of our customers help us to protect our water sources, Please exercise care and caution If hiking, hunting or traveling through the water shed areas of the Muleshoe and Plane Nine reservoirs so that these sources of water supply do not become contaminated by activities Ini the watershed. Please also report Immediately, to the HBA, any Ilttering, spills or dumplng that may impact the watershed areas and notlfy the Hollidaysburg Borough Police of any: suspicious or unusual activities that may be observed In or around the reservoir sites or their respective watershed areas. AND CONSERVE... The Authority would also request that customers conserve our water resources by conserving water in the home and at places of work. Repair leaks in your home, such as dripping faucets and leaks inside of the toilet as soon as they are discovered. Leaks, even small faucets drips, can waste: significant amounts of water. Leaks inside a toilet can waste up to 200 galions of water per day, or more. Test for leaks in a toilet by placing a few drops of food coloring in the tollet tank. If the colored water appears in the bowl (without flushing), the tollet is leaking, If you have a leaking faucet, a simple replacement of a rubber washer may: save, gallons of water from being wasted down the drain. In addition, hot water leaks waste not only water, but energy to heat the water. Please consider the following tips for conserving water around the home: insiail luw consumpiiun iuileis wienremudeling UI during lew cunsiruction; pidue d weighieu pidsiic jugi in ihe Luilei iank iu dispiaue dud Sdve dii equal amount of water with each flush; install low-flow aerators on all faucets and low-flow shower heads on the shower spigot; turn the water off while brushing teeth or shaving; take showers instead of baths and turn off water while soaping or shampooing; refrigerate a bottie of water instead of letting the faucet water flow until cold enough to drink; do not pre-rinse dishes prior to loading in the dishwasher; use the proper water level or load size selection on washing machines; use a broom instead of a hose to clean driveways and sidewalks; water the lawn and garden during the coolest part of the day; mulch around trees and shrubs; and use native plants in landscaping since they require less care and watering than ornamental varieties.
