Summary
PFAS above the 2024 federal limits. Systems have until 2029 to meet the PFAS limits.
Is it an emergency? No: PFAS limits are about years of exposure, not a glass of water, and nothing in EPA's data calls for you to stop drinking the water today. If your utility ever issues a boil-water or do-not-drink notice, follow it.
- PFAS
- Above limitPFOA, PFOS above the federal limit in EPA's 2023–2025 testing (PFOA 4.35 ppt vs a limit of 4 ppt, PFOS 10.4 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
- Lithium
- Above screening levelHighest result 27.7 ppb. EPA uses 10 ppb to decide what to study further. It is not a health limit, and there is no federal limit for lithium. About 1 in 4 systems tested were above it.
- Lead
- Below action level3 ppb (parts per billion) at the 90th percentile: 9 in 10 homes sampled were at or below it. Action level 15 ppb, falling to 10 ppb in Nov 2027. Monitoring period ending Dec 2023. Your home's pipes can make yours higher.
- Violations
- None health-basedNo health-based violations since 2016.
- Pregnant, or mixing baby formula with tap water? Babies drink more water for their size, so PFAS exposure matters more for them. Consider bottled water or a filter certified for PFAS for formula, and ask your doctor. Health effects.
- To lower your PFAS exposure now, a home filter certified for PFAS reduction works (reverse osmosis, or activated carbon certified to NSF/ANSI 53 or 58). Filters for these results.
- Built before 1986, or not sure what your service line is made of? Check your service line and test your tap. Utility data can't show your pipes.
- Tested your own tap? Compare your result with these numbers. Moving? Compare this system with another.
- Read City of Taneytown's annual water quality report (Consumer Confidence Report). It lists every regulated contaminant tested and is usually on the utility's website or mailed with your bill, and you can also request it at (410) 751-1100. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 7 entry points tested Jan 2024 to Jul 2024. "Average" is the highest entry-point average (non-detects counted as zero), the way EPA compares UCMR 5 results to the limits. ppt = parts per trillion. These results do not determine compliance.
| Contaminant | Highest average |
|---|---|
| PFOA Above limit Limit 4 ppt | 4.35 ppt 1.09× the limit |
| PFOS Above limit Limit 4 ppt | 10.4 ppt 2.6× the limit |
| PFHxS Detected, below limit Limit 10 ppt | 4.2 ppt 42% of the limit |
| PFNA Not detected Limit 10 ppt | – |
| HFPO-DA (GenX) Not detected Limit 10 ppt | – |
| Hazard Index (a combined score for PFHxS, PFNA, GenX and PFBS, where above 1 is over the limit) Detected, below limit Limit 1 | 0.42 |
| PFBS Detected, below limit Guideline 2,000 ppt | 14.4 ppt |
| PFBA Not detected Guideline 6,000 ppt | – |
| PFHxA Detected, below limit Guideline 3,000 ppt | 2.25 ppt |
| PFPeA Detected, no limit | 4.95 ppt |
For context: the PFOA average is higher than at 84% of the Maryland systems EPA tested and the PFOS average is higher than at 97% of the Maryland systems EPA tested.
29 PFAS tested, 6 detected at least once. "Not detected" means below EPA's reporting limit (about 2 to 20 ppt depending on the chemical), not proven zero. PFAS not listed were not detected. The limits for PFHxS, PFNA, GenX and the Hazard Index were proposed for rescission in May 2026. That proposal is not final. Systems have until 2029 to meet the limits.
Lithium
Detected in 14 of 14 samples. Highest result 27.7 ppb. EPA's non-enforceable screening level is 10 ppb. Above screening level The screening level is how EPA decides what to study further, not a health limit. There is no federal limit for lithium and no filter is certified to remove it. About lithium.
Lead and copper
Latest 90th percentile: 3 ppb lead (Jan 2021 – Dec 2023). Below action level
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2021 – Dec 2023 | 3 ppb |
| Jan 2018 – Dec 2020 | 2 ppb |
| Jan 2015 – Dec 2017 | -2 ppb |
Earlier results (9)
| Jan 2012 – Dec 2014 | 0 ppb |
| Jan 2009 – Dec 2011 | 0 ppb |
| Jan 2006 – Dec 2008 | 7 ppb |
| Jan 2003 – Dec 2005 | 5 ppb |
| Jan 2000 – Dec 2002 | 3 ppb |
| Jan 1997 – Dec 1999 | 6 ppb |
| Jan 1996 – Dec 1998 | 3 ppb |
| Jan 1995 – Dec 1995 | 6 ppb |
| Jan 1994 – Dec 1994 | 5 ppb |
Lead comes from pipes and fixtures, not the source water, so it varies home to home. The 90th percentile means 9 in 10 sampled homes were at or below it. More on lead.
Violations
Health-based violations mean a contaminant exceeded a limit or a required treatment step was missed. Monitoring and reporting violations mean required tests or reports were late or missing, so the water's quality during that time is unknown. The total includes every violation in EPA's records, most of them paperwork.

Questions
Is City of Taneytown water safe to drink?
City of Taneytown has no health-based violations since 2016. EPA testing found PFAS above the 2024 federal limits, which systems must meet by 2029. Federal data can't tell you about your own pipes: lead comes from service lines and plumbing, so test your tap if your home was built before 1986. For the official word, read the utility's annual Consumer Confidence Report.
Does City of Taneytown water have PFAS?
Yes. EPA's 2023–2025 testing of City of Taneytown found 6 PFAS at least once. The highest entry-point averages were above the federal limit for PFOA and PFOS: PFOA 4.35 ppt, PFOS 10.4 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).
What is the lead level in City of Taneytown water?
The most recent 90th-percentile lead result for City of Taneytown is 3 ppb, for the period ending Dec 2023. The federal action level is 15 ppb, falling to 10 ppb in November 2027. The 90th percentile means 9 in 10 homes sampled were at or below this number. Individual homes can be higher.
