01The verdict: is Alabaster water safe?

Alabaster's tap water meets most EPA standards but has areas that warrant attention. With a grade of A- (86.9/100), some contaminant levels or compliance issues suggest that residents may benefit from additional filtration. The city's 1 water system serves approximately 41,061 residents using surface water (rivers, lakes, or reservoirs).

The concern

Chlorate is over its legal limit

Measured at 830.0 µg/L against the EPA Lifetime HA of 210 µg/L. The ledger below shows how far over — and which filter removes it.

The good news

Lead is well under the limit

90th-percentile lead is 1.1 ppb — beneath the 15 ppb federal action level and under the 5 ppb watch threshold.

Keep watching

lithium is approaching its limit

Measured at 12.4000 µg/L — 120% of the 0.004 µg/L limit. Within the rules, but with less headroom than you'd want.

See the ledger ↓

Alabaster's drinking water received a grade of A- (86.9 out of 100), indicating good water quality. The city's 1 water system serves approximately 41,061 residents using purchased surface water.

Lead levels were measured at 1.1 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 9 PFAS compounds, with levels exceeding EPA maximum contaminant levels in the water supply. The system has 54 violations on record, including 2 health-based violations. 1 remains unresolved.

Alabaster ranks #171 out of 351 cities in Alabama for water quality, placing it mid-range in the state. The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection. Of particular concern: PFAS "forever chemical" levels exceed the 2024 EPA maximum contaminant levels. These synthetic compounds don't break down naturally and require specialized filtration such as reverse osmosis or granular activated carbon. Hexavalent chromium (chromium-6) was detected at 0.26 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.

05Pressure on Alabaster's watershed

Outside forces that shape what reaches the treatment plant. None of these is a verdict on the tap by itself — but each adds pressure worth knowing about.

Industrial discharge

Present — monitored

5 facilities within 10 miles reported 52 lb released to surface water in the latest EPA Toxics Release Inventory. Proximity doesn't equal tap contamination — treatment and hydrology decide — but it's pressure on the watershed.
