What Hoover's Water Means for Your Home
Hardness: 93 PPM - Low Concern
Hoover's water is moderately hard at 93 PPM. You'll see some spotting on glassware and a film on shower doors over time, but it's not the kind of hardness that demands a full softener. A salt-free conditioner is worth considering if you have a tankless water heater or high-end fixtures.
Contaminants & Safety
Disinfection byproducts are the notable finding here. Hoover's water has TTHMs at 30.2 ppb and HAA5 at 27.1 ppb — both within legal limits, but the EWG health guidelines are far stricter. These byproducts form when chlorine reacts with organic matter during treatment. A whole-house activated carbon filter reduces both chlorine and its byproducts. Want the full picture?

What's in the Treatment Process
Hoover's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 30.2 ppb (38% of the legal limit, but 201x the EWG guideline) and HAA5 at 27.1 ppb (45% of the legal limit, but 271x the EWG guideline). These are within legal limits, but the EWG sets much tighter thresholds based on cancer-risk research. A whole-house activated carbon filter reduces both chlorine and byproducts.
Chromium-6 was detected at 0.0778 ppb, which is 3.9x the EWG health guideline. There's no separate federal limit for chromium-6, only total chromium. A reverse osmosis system is the most effective removal method. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.

Recommendations for Hoover Homes
Quick Fix for Chlorine: Shower Filter
At 1.2 mg/L chlorine, many Hoover residents notice dry skin, brittle hair, and that "pool smell" in the shower. A shower filter installs in 5 minutes, no tools needed.

About Hoover's Water Supply
Water Utility: Birmingham Water Works
Water Source: Cahaba River (Surface Water)
Population Served: 585,000
Hardness: 93 PPM (5.4 grains per gallon)
Hoover's drinking water comes from surface sources — Cahaba River. Surface water requires more extensive treatment than groundwater, including coagulation, filtration, and disinfection. This heavier chlorination is why disinfection byproducts tend to be higher in surface-supplied systems. On the upside, surface sources often deliver softer water than deep aquifers. The system serves 585,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Birmingham Water Works's Consumer Confidence Report (CCR) or test your own tap.
