Is Buford Tap Water Safe to Drink? 2026 Guide

Buford has its own city water system serving 8,482 residents inside city limits, plus many surrounding "Buford" addresses that are actually served by Gwinnett County Department of Water Resources. Both utilities draw from the same source - Lake Lanier - but they treat the water at different facilities.

Buford city water is treated locally before distribution. Gwinnett County DWR draws from Lake Lanier and treats it at either the Shoal Creek Filter Plant or the Lanier Filter Plant, then distributes it across a much larger Gwinnett service footprint.

How can I tell who supplies my water? Check your water bill. Buford addresses may be served by Buford city water OR Gwinnett County DWR depending on your exact location. Both draw from Lake Lanier, but use different treatment facilities and have slightly different testing results.

Either way, your source is Lake Lanier - the same reservoir that supplies more than a million North Georgians. For a deeper look at the source itself, see our Lake Lanier Drinking Water Guide. For nearby comparisons on other Lake Lanier-fed cities, see our guides for Cumming, Dacula, and Gainesville.

EWG's database, drawing on Buford water testing data from 2018–2023, identifies 9 detected contaminants in Buford tap water. Of those, 8 exceed EWG's stricter health-based guidelines.

Disinfection Byproducts (DBPs)

DBPs form when chlorine reacts with naturally occurring organic matter in Lake Lanier water. Disinfection is necessary, but studies have linked long-term DBP exposure to elevated health risks.

• TTHMs (Total Trihalomethanes): 39.7 ppb - 264x EWG guideline
• HAA5 (Haloacetic acids, 5-compound group): 24.8 ppb - 248x EWG guideline
• Trichloroacetic acid: 13.7 ppb - 137x EWG guideline
• Chloroform: 31.5 ppb - 79x EWG guideline
• Bromodichloromethane: 3.72 ppb - 62x EWG guideline
• Dichloroacetic acid: 11.1 ppb - 55x EWG guideline

Other Contaminants

Nitrate/nitrite: 0.283 ppm - 2x EWG guideline. May be associated with agricultural runoff and septic discharge in the upstream watershed.

The utility's CCR reports compliance with federal Safe Drinking Water Act standards during the most recent EPA-assessed quarter.

If Buford's water is in federal compliance, why do so many contaminants exceed health guidelines?

EWG points to a regulatory gap: federal Maximum Contaminant Levels for many drinking water contaminants haven't been updated in nearly 20 years. EWG's guidelines reflect more current research on long-term exposure, especially for disinfection byproducts.

Two things can be simultaneously true:

• Buford water meets all federal Safe Drinking Water Act requirements.
• Independent testing identifies multiple contaminants above current health-based recommendations.

For most healthy adults, occasional consumption isn't an immediate concern. For infants, pregnant women, immunocompromised individuals, and households thinking about long-term cumulative exposure, it's worth knowing what's in the water and weighing filtration options.

Yes. Buford water is moderately hard thanks to natural calcium and magnesium picked up in the Lake Lanier watershed. Hardness is consistent across both Buford city water and Gwinnett County DWR service in this part of the lake.

Most Buford-area homeowners notice some or all of these signs:

• White spots and film on dishes and glassware
• Cloudy or "etched" looking glass after the dishwasher
• Soap that won't lather; "slimy" feel after showering
• Dry skin sensations and dull-feeling hair, especially in winter
• Scale buildup on faucets, showerheads, and toilet bowls
• White crust around water heater fittings and hot water lines
• Reduced water heater efficiency and shorter appliance lifespan

Hard water isn't classified as a health concern, but it absolutely shortens the life of plumbing, fixtures, and appliances. A water softener uses ion exchange to reduce hardness minerals - separate from filtration, which targets contaminants.

Buford homeowners report a familiar set of taste and smell complaints, most of them tied to Lake Lanier as a shared source.

Chlorine taste and smell: Most noticeable in summer when utilities increase disinfectant levels to keep water safe in longer distribution lines. Carbon filtration is highly effective at reducing this.

Earthy or musty taste in fall: This is the Lake Lanier seasonal turnover effect. Naturally occurring MIB and geosmin - produced by algae and bacteria - can cause an earthy or musty taste at the tap. Both are common in surface water systems and not considered harmful at typical levels.

"Different" water at neighbor's house: Because Buford addresses are split between Buford city water and Gwinnett County DWR, two homes a few blocks apart may notice slightly different taste and smell profiles even though both pull from Lake Lanier.

Different filtration systems address different problems. For Buford water specifically, here's what tends to help:

Pitcher filters (Brita, PUR, etc.): Reduce chlorine taste. Limited effect on disinfection byproducts. No effect on hard water. Reasonable starting point for renters.

Faucet-mount filters: Better than pitcher filters for chlorine and some VOCs. Cartridge specs vary widely.

Refrigerator filters: Only treat the water flowing to the fridge dispenser. Don't help with showers, dishwashers, washing machines, or other faucets.

Under-sink reverse osmosis (RO): The most effective option for drinking water specifically. Reduces nearly all of Buford's elevated contaminants - TTHMs, HAA5, trichloroacetic acid, chloroform, nitrates, lead, and PFAS. Installed at the kitchen sink.

Whole-home carbon filtration: Addresses chlorine, taste, smell, and many DBPs at every faucet and shower in the home. Doesn't address hard water on its own.

Water softener: Targets hard water symptoms. Doesn't address contaminants.

For most Buford homes on Lake Lanier source water, the comprehensive setup is whole-home carbon filtration + under-sink RO + a water softener.

For a typical Buford home dealing with the standard issues - chlorine in summer, fall taste/odor, DBPs above health guidelines, and hard-water scale - we generally recommend a whole-home carbon filtration system to handle taste/smell and DBPs at every tap, an under-sink RO system for drinking and cooking water, and a water softener if hardness symptoms are present.
