What Sugar Land's Water Means for Your Home
Hardness: 90 PPM - Low Concern
Sugar Land's water is moderately hard at 90 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
Forever chemicals (PFAS) are worth watching here. Sugar Land has PFOA at 4.05 ppt, exceeding the EPA's 2024 limit of 4 ppt per compound. PFAS are synthetic compounds that accumulate in your body over time. A certified carbon filter or reverse osmosis system with NSF P473 certification is the most effective protection. See the regulatory timeline.
What's in the Treatment Process
Chromium-6 was detected at 0.655 ppb, which is 33x 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.

About Sugar Land's Water Supply
Water Utility: City of Sugar Land
Water Source: Brazos River Authority, groundwater (Surface Water)
Population Served: 90,909
Hardness: 90 PPM (5.3 grains per gallon)
Sugar Land's drinking water comes from surface sources — Brazos River Authority, groundwater. 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 91,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Sugar Land's Consumer Confidence Report (CCR) or test your own tap.
