Bacteria & E. Coli
Met standard
Water is sampled routinely for total coliform and E. coli — indicators of possible contamination. In 2025 there were zero positive samples and no violations.
Every year the Borough tests its drinking water against federal and state safety limits and reports exactly what we find — a report the EPA requires and calls the Consumer Confidence Report (CCR). Here are the 2025 results in plain language: what we tested for, what we found, and how each result compared to the limit.
In 2025, every substance the Borough tested for met or was below every federal and state limit, and Tyrone recorded no drinking-water violations. The Borough draws its water from the Sink Run #2 Reservoir in Snyder Township — which holds about 88 million gallons — and treats it at the Borough’s own filtration plant, capable of producing up to 2.3 million gallons a day. Residents used about 573,000 gallons a day last year.
2025 Annual Drinking Water Quality Report · Public Water System ID (PWSID) 4070021 · published 2026. Some results are carried forward from earlier years where the state allows less-frequent monitoring; each is dated below or in the full report.
Finding small amounts of certain substances in drinking water is normal. As rain and groundwater move through soil and rock they naturally pick up minerals, and treatment adds a small, carefully controlled amount of chlorine to keep the water free of bacteria. What matters is the amount — and in 2025 every amount was within the legal limit. The two notices below are required by the EPA and apply to every public water system.
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 microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791).
Lead in drinking water comes primarily from materials in service lines and home plumbing, not from the Borough’s water itself — and Tyrone’s 2025 lead result was non-detect, with no homes above the action level. Still, you can reduce any exposure from your own plumbing: when water has been sitting for several hours, run the tap (or take a shower or run a load of laundry) for a few minutes before drinking or cooking, and consider a filter certified to reduce lead. If you would like your water tested, contact Kimberlee LaRosa at (814) 684-1330. To see the pipe material on your own line, search the Service Line Inventory. More information is available from the EPA at epa.gov/safewater/lead (opens in a new tab).
Each bar shows the highest level we detected as a share of the legal limit. A bar reaching the full width would mean a result right at the limit — shorter is better. The actual numbers are printed on every row, so you never have to read the chart alone.
ppm = parts per million · ppb = parts per billion · pCi/L = picocuries per liter (radioactivity) · the legal limit is the EPA/PA Maximum Contaminant Level (MCL), or for chlorine the Maximum Residual Disinfectant Level. Exact values, sample dates and goal levels (MCLG) are in the full report below.
Lead and copper are measured differently from the results above. Because they usually come from household plumbing rather than the Borough’s mains, they’re tested at the tap in a sample of homes. The result is the 90th-percentile value across those homes, compared to an action level. In 2025, zero sites were above the action level for either metal.
This report covers system-wide testing. The Borough’s Service Line Inventory lets you look up the pipe material for your specific address — Borough side and customer side.
Some protections aren’t a single number versus a limit — they’re about whether the treatment process is working. All three met their standards in 2025.
Met standard
Water is sampled routinely for total coliform and E. coli — indicators of possible contamination. In 2025 there were zero positive samples and no violations.
Met standard
Turbidity shows how well filtration is removing particles. 100% of monthly samples met the standard, and the highest single reading was 0.24 NTU against a 1 NTU limit.
Met standard
Chlorine keeps water safe from the plant to your tap. The entry-point disinfectant residual stayed within the required range, and total organic carbon removal met its treatment requirement.
The page above is a plain-language summary. The complete 2025 Consumer Confidence Report — with every sample date, goal level (MCLG) and the EPA’s required health language — is the official record.
