- Where does Chickasaw's water come from?
- Served by MAWSS. Older galvanized service lines in the historic shipyard housing keep pipe-era metals a live question — the reason a test comes before any equipment here. EPA SDWIS classifies the source-water type as surface water — meaning continuous turbidity monitoring and disinfection are the headline treatment requirements.
- Does Chickasaw tap water have PFAS?
- Yes — the most recent EWG snapshot for MAWSS, the utility serving Chickasaw, flagged 3 PFAS compounds above EWG's health guideline: PFHXS, PFNA, and PFOA. PFAS pass through standard municipal treatment; the residential answer is a point-of-use reverse-osmosis system or an NSF/ANSI 53-certified activated-carbon block rated for PFOA/PFOS reduction.
- What contaminants are in Chickasaw's tap water?
- The most recent EWG snapshot for MAWSS (which serves about 279,000 people across Mobile County, including Chickasaw) flagged 12 contaminants above EWG's health guidelines. The top three by detection prominence: Bromodichloromethane (2.23 ppb, activated-carbon block); Chlorite (452.2 ppb, reverse osmosis); Chloroform (7.57 ppb, activated-carbon block). EWG's guidelines are tighter than EPA's legal limits — being above them is not an EPA violation, but for Chickasaw households deciding on a residential filter stack, the EWG list is the working signal those products are designed around.
- Is Chickasaw's water utility (MAWSS) compliant with EPA standards?
- EPA's ECHO database currently shows MAWSS as "In Compliance" under the Safe Drinking Water Act. EPA's most recent on-site inspection was recorded 2025-06-26. Compliance does not mean contaminant-free — EWG's health guidelines are tighter than EPA's legal limits — but it does mean the federally-tracked enforcement risk for Chickasaw customers is low.
- What's the hardness of Chickasaw water?
- USGS site-level data for Mobile County puts median groundwater hardness at 1.9 gpg (grains per gallon) with a median pH of 6.69 — the groundwater baseline behind every well and utility source in the county. For MAWSS customers in Chickasaw, the utility's distribution-end hardness can differ from the raw groundwater if the plant softens; the working planning number for sizing a residential softener is the county median plus or minus the figure on the utility's published CCR.
- What's a 100-year storm in Chickasaw?
- NOAA Atlas 14 puts the 100-year, 24-hour rainfall depth for Chickasaw at 14.6 inches (90% confidence interval 11.2–18.7 in.). For comparison, the 10-year depth is 8.5 in. and the 25-year depth is 10.7 in. — useful context when sizing sump-pump backup and elevating filtration equipment above expected flood depths.
- How often does Chickasaw get hurricanes?
- Between 2020 and 2025, NOAA logged 5 named storms touching Mobile County, AL, including Hurricane Sally in 2020 plus 4 additional tropical systems (Cristobal, Zeta, Claudette). Post-storm power outages and boil-water notices are the practical residential exposure in Chickasaw — a whole-house sediment filter ahead of any softener or RO stage protects the equipment when system pressure returns.
- How old are the homes in Chickasaw?
- Per the latest American Community Survey, the median year-built for housing in Chickasaw is 1963. Pre-1970 stock commonly carries galvanized service lines and lead-soldered copper joints — test first, then a whole-house point-of-entry filter ahead of an under-sink drinking-water stage is the standard retrofit pattern.
