Ramsey Water Company, Inc. water quality
Ramsey, IN · serves 16,475 people (6,590 connections) · Groundwater · Local government · EPA ID IN5231005
Data: U.S. EPA · How we read the data · How we check it
Buys water from Corydon Water Works, Edwardsville Water Corporation, South Harrison Water Corporation, Indiana American Water – Southern Indiana. Treated water bought from another system can carry that system's contaminants.
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 above the federal limit in EPA's 2023–2025 testing (PFOA 4.6 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
- Lead
- Below action level0 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
- Resolved1 health-based violation since 2016, most recently Feb 2026.
- 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 Ramsey Water Company, Inc.'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 (812) 267-9594. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested Mar 2024 to Sep 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 | 4.6 ppt 1.15× the limit |
| PFOS Not detected Limit 4 ppt | – |
| 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 PFOA average is higher than at 97% of the Indiana 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 2 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 0 ppb lead (Jan 2021 – Dec 2023). Below action level
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2021 – Dec 2023 | 0 ppb |
| Jan 2018 – Dec 2020 | 0 ppb |
| Jan 2015 – Dec 2017 | 0 ppb |
Earlier results (9)
| Jan 2012 – Dec 2014 | 5 ppb |
| Jan 2011 – Dec 2013 | 0.1 ppb |
| Jan 2008 – Dec 2010 | 1.3 ppb |
| Jan 2005 – Dec 2007 | 3 ppb |
| Jan 2002 – Dec 2004 | 2 ppb |
| Jan 1999 – Dec 2001 | 1 ppb |
| Jan 1997 – Dec 1997 | 2 ppb |
| Jan 1996 – Dec 1996 | 5 ppb |
| Jan 1995 – Dec 1995 | 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
| When | What happened |
|---|---|
| Feb 2026 | A required step to remove or kill germs (filtration, disinfection or fixing a contaminated well) was not done properly. EPA record: Groundwater Rule · Treatment Technique (SWTR and GWR) (limit ) 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 | 54.1 ppb | 300 ppb |
| Molybdenum | 5.6 ppb | 40 ppb |
| Vanadium | 0.4 ppb | 21 ppb |
| Chromium-6 | 0.14 ppb | – |
| Strontium | 1.7 ppm | 1.5 ppm |
| 1,4-Dioxane | 0.25 ppb | 0.35 ppb |
