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 limitPFOS above the federal limit in EPA's 2023–2025 testing (PFOS 4.63 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
- Lead
- Out of dateEPA's national database has no lead results for this system since 2014 (then 6 ppb, 90th percentile). Systems this size normally test every one to three years, so this most likely means newer results were not reported to EPA, not that testing stopped. Ask the utility for its latest results.
- Violations
- Resolved3 health-based violations since 2016, most recently Apr 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 PRASA – Manati East'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 (787) 620-2277. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 3 entry points tested Sep 2023 to Jun 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 Not detected Limit 4 ppt | – |
| PFOS Above limit Limit 4 ppt | 4.63 ppt 1.16× the limit |
| PFHxS Not detected Limit 10 ppt | – |
| 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) Not detected Limit 1 | – |
| PFBS Not detected Guideline 2,000 ppt | – |
| PFBA Not detected Guideline 6,000 ppt | – |
| PFHxA Not detected Guideline 3,000 ppt | – |
For context: the PFOS average is higher than at 86% of the Puerto Rico systems EPA tested.
29 PFAS tested, 1 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
Not detected in 12 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 6 ppb lead (Jul 2014 – Dec 2014). No results since 2014
This is the newest lead result in EPA's national database. Utilities report lead results to their state, and states pass them to EPA. Gaps like this usually mean the newer results did not reach EPA's database, not that the utility stopped testing. Results this old may not reflect the water today. Ask the utility or your state drinking water program for the latest lead monitoring.
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jul 2014 – Dec 2014 | 6 ppb |
| Jul 2011 – Dec 2011 | 6 ppb |
| Jul 2008 – Dec 2008 | 4 ppb |
Earlier results (9)
| Jul 2007 – Dec 2007 | 12 ppb |
| Jun 2006 – Sep 2006 | 9 ppb |
| Jul 2005 – Dec 2005 | 2 ppb |
| Jul 2004 – Dec 2004 | 3.7 ppb |
| Jul 2003 – Dec 2003 | 8.1 ppb |
| Jul 2002 – Dec 2002 | 8.1 ppb |
| Jul 2001 – Dec 2001 | 7.6 ppb |
| Jan 2001 – Jun 2001 | 4.9 ppb |
| Jan 1993 – Jun 1993 | 18 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
| When | What happened |
|---|---|
| Jan 2016 – Apr 2016 2 times | The running annual average for TTHM was above the legal limit. EPA record: TTHM · Maximum Contaminant Level Violation, Average · measured 0.094 mg/l (limit 0.080 mg/L) Resolved |
| Jan 2016 | The running annual average for Total Haloacetic Acids (HAA5) was above the legal limit. EPA record: Total Haloacetic Acids (HAA5) · Maximum Contaminant Level Violation, Average · measured 0.066 mg/l (limit 0.060 mg/L) Resolved |
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.
Earlier EPA testing (2013–2020)
| Contaminant | Highest | Guideline |
|---|---|---|
| Manganese | 1.67 ppb | 300 ppb |
| Chlorate | 350 ppb | 210 ppb |
| 1,2,3-Trichloropropane (TCP) | 0.03 ppb | 0.0004 ppb |
| Strontium | 0.14 ppm | 1.5 ppm |
| Vanadium | 2.41 ppb | 21 ppb |
| Chromium-6 | 3.21 ppb | – |

Questions
Is PRASA – Manati East water safe to drink?
PRASA – Manati East had 3 health-based violations since 2016, all since resolved. 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 PRASA – Manati East water have PFAS?
Yes. EPA's 2023–2025 testing of PRASA – Manati East found 1 PFAS at least once. The highest entry-point averages were above the federal limit for PFOS: PFOS 4.63 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).
What is the lead level in PRASA – Manati East water?
The most recent 90th-percentile lead result for PRASA – Manati East is 6 ppb, for the period ending Dec 2014, which is more than five years old. 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.
