What Tyler's Water Means for Your Home
Hardness: 75 PPM - Low Concern
Tyler's water is moderately hard at 75 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. Tyler's water has TTHMs at 50.3 ppb and HAA5 at 25.5 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
Tyler's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 50.3 ppb (63% of the legal limit, but 335x the EWG guideline) and HAA5 at 25.5 ppb (43% of the legal limit, but 255x 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 0.0635 ppb, which is 3.2x 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.

Quick Fix for Chlorine: Shower Filter
At 1 mg/L chlorine, many Tyler residents notice dry skin, brittle hair, and that "pool smell" in the shower. A shower filter installs in 5 minutes, no tools needed.

About Tyler's Water Supply
Water Utility: City of Tyler Water Utilities
Water Source: Lake Palestine, Lake Tyler (Surface Water)
Population Served: 107,000
Hardness: 75 PPM (4.4 grains per gallon)
Tyler's drinking water comes from surface sources — Lake Palestine, Lake Tyler. 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 107,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Tyler Water Utilities's Consumer Confidence Report (CCR) or test your own tap.
