National Water Quality Month: Understanding Atlanta’s Water Quality

August 28, 2026

August is National Water Quality Month, a time dedicated to reflecting on the importance of the water we drink, bathe in, and use every day. Here in Atlanta, we are fortunate to have a complex, regulated water infrastructure that brings fresh water into our homes, primarily from the Chattahoochee River. However, even with municipal treatment, many homeowners often wonder about the quality of the water running through their taps.

Understanding your home’s water quality isn’t just about curiosity: it’s about peace of mind, the longevity of your plumbing, and the health of your household.

At Plumb Works, we want you to have up-to-date information about Atlanta’s water quality.

Where Does Atlanta’s Water Come From?

Most of the water in the Atlanta metropolitan area is sourced from the Chattahoochee River. The municipal treatment process is rigorous, adhering to strict federal and state standards set by the Environmental Protection Agency (EPA) and the Georgia Environmental Protection Division. By the time it reaches your pipes, the water has gone through multiple stages of filtration and disinfection to ensure it is safe for consumption.

Why Do Some Homeowners Still Have Concerns?

While municipal water is treated to be safe, there are a few reasons why you might notice differences in the water quality within your home:

  • Aging Pipes: If you live in an older home, the internal plumbing pipes, or even the service line connecting your home to the city main, may be aging. Corrosion in these pipes can sometimes introduce particles or metallic tastes into your water.
  • Mineral Content: Atlanta’s water is generally considered "soft" to "moderately hard." Depending on your specific neighborhood and the plumbing materials used, you may occasionally see mineral buildup (often white, chalky residue) around your faucets or showerheads.
  • Sediment: During periods of high demand or maintenance on city water lines, it is possible for sediment to get stirred up, leading to temporary cloudiness in your tap water.

How to Assess Your Home Water Quality

If you are concerned about your water, there are simple steps you can take to monitor it:

  1. Observe Your Water: Pay attention to clarity, smell, and taste. If the water looks discolored (brown or yellow) or has a strong chemical or "rotten egg" odor, these are signs that warrant a closer inspection.
  2. Check Your Fixtures: Are you seeing frequent sediment buildup on your faucet aerators or showerheads? This might indicate that your water has high mineral content that could benefit from a filtration system.
  3. Consult a Professional: If you have persistent concerns, the best approach is to contact a licensed plumber. A professional can inspect your home’s plumbing system to identify if the issue is originating from city supply lines or from your home’s internal pipes.

Improving Your Water Quality

For homeowners looking for an extra layer of protection, technology offers excellent solutions. Whole-home water filtration systems are becoming increasingly popular. These systems are installed where the main water line enters your home, effectively filtering the water before it reaches your showers, sinks, and appliances. Benefits include:

  • Better-tasting water from every tap.
  • Protection for your appliances, such as your water heater, dishwasher, and washing machine, by reducing mineral buildup.
  • Gentler water for your skin and hair.

Whether you are interested in a whole-home filtration system, a water softener, or simply need an inspection of your current plumbing system, Plumb Works is here to help you navigate your options.

Q&A Recap

To help you find answers quickly, we’ve compiled common questions about home water quality.

  • Is Atlanta tap water safe to drink?

    Yes. Municipal water in Atlanta undergoes extensive treatment and regular testing to meet or exceed federal and state safety standards set by the EPA.

  • Why does my tap water sometimes look cloudy?

    Cloudy water is often caused by tiny air bubbles trapped in the water, especially in colder months. If the water clears up after sitting for a few minutes, it is generally harmless. However, if the water remains discolored or has an odd odor, contact a plumbing professional.

  • What is a whole-home water filter?

    A whole-home water filtration system is installed at your home’s main water entry point. It filters water for the entire house, ensuring that the water used in your kitchen, bathrooms, and laundry room is free from sediment and impurities.

  • How do I know if I need a water softener?

    If you notice white, crusty buildup on your faucets, stiff laundry after washing, or dry, itchy skin after showering, your home may benefit from a water softener to reduce hard water minerals.

Being proactive remains a key element of a successful business, and it certainly holds true when preparing for the possible devastating effects of stormy season. Spring remains one of the Atlanta area’s rainiest times of the year. According to Weather Spark, the average monthly rainfall from March through May ranges from 3 to 4.6 inches. Heavy spring storms can rain hard on a commercial facility. If unprepared, it can potentially lead to serious problems, causing everything from business downtime to costly repercussions. The following are several heavy rain-related issues that can cast a dark cloud on a commercial building and how to avoid them. Sump Pump: Fighting the Flood When it comes to flooding, stormwater remains a dreaded culprit. Having a properly functioning sump pump can help proactively help fight a flood. A sump pump collects groundwater from around a building’s foundation and pumps it away from the structure, deterring damage. Plumb Works suggests all businesses have one, especially those with a crawlspace or basement. Consult the experts at Plumb Works for sump pump installation, replacement, and preventative maintenance. Protection from Sewer Backups Heavy rains can overload a city’s sewer system. Backwater valves, a specific type of backflow prevention device, protect businesses from sewer backups by allowing wastewater out, but automatically closing to keep sewage from flowing backward. Plumb Works can install, test, and make sure your backwater valve is working properly. The Importance of Storm Drains Commercial storm drains are equipped to drain excess rain and groundwater from the areas surrounding a business, such as parking lots and sidewalks, preventing flooding, damages, and unsafe conditions. Some storm drain systems include a catch basin, which captures stormwater and separates any debris that may have come along with it. Having Plumb Works inspect, clean, and repair storm drains and catch basins can help businesses avoid a flood of unwanted costs. Cutting Out Grease Commercial kitchens require a grease trap, which keeps the plumbing system from being impacted by an overload of grease. If a grease trap isn’t functioning properly, it can have an adverse effect on a plumbing system during heavy rain. Too much grease limits pipe capacity, which can cause heavy rain to overwhelm a system, leading to backups. To avoid this, consult a plumbing professional company like Plumb Works that specializes in grease trap services. Avoiding Clogged Drains Plumbing systems in commercial facilities often fall prey to clogged pipes due to unwanted items being flushed or disposed of down drains. This can further complicate things when a mass amount of rain overwhelms a plumbing system. Businesses experiencing frequent clogs can benefit from hydro jetting. The most effective drain-cleaning solution available, hydro jetting uses high-pressure water jets to blast through clogged drains and restore peak plumbing performance. Schedule hydro jetting in advance of the rainy season to make sure pipes are functioning at their best under any possible pressure.
