As the third largest city in Texas, millions of people call Dallas home. If you’re one of those people you might be concerned with Dallas water quality. Is Dallas tap water safe to drink? You’ll be happy to know that according to a variety of organizations, including the EPA, Dallas drinking water is safe to consume. However, that does not mean that Dallas tap water is free of contaminants. If you want to know what’s affecting your Dallas water quality and what you can do to improve it, keep reading.

Where Does Dallas Drinking Water Come From?

Dallas tap water comes from a variety of area reservoirs. More specifically, the water in Dallas comes from Lake Ray Hubbard, Lake Grapevine, Lake Lewisville, Lake Ray Roberts, and Lake Tawakoni. All Dallas drinking water comes from surface water from the bodies of water already mentioned. Ground water is not used as a source of Dallas tap water.

Even after water is treated there are chances for pollutants to end up in your Dallas tap water. As water travels from the treatment plant to your home it can come in contact with minerals, metals, and even chemicals that arise during the treatment of your water. These things can also affect the taste of your water, especially if large amounts of chlorine or other chemicals are necessary to clean the water before it gets to your faucet. Using a water filter will remove the remaining remnants of pollutants. It will also make your water taste and smell better, too.


Can you Drink Dallas Tap Water from the Faucet?

Dallas tap water passes the guidelines set from the EPA and other agencies, but you might still want to be wary of drinking water straight from the source. For starters, microplastics, disinfection byproducts, and other pollutants are still in your water after it has been treated. Some of these things can have an effect on your health, depending on what they are. Meanwhile, others will just make the water taste bad. If your water tastes bad or you want to get rid of the contaminants that remain after water treatment, you can use a water filter to treat your water a second time. A water filter is going to remove much of the remaining toxins in your Dallas drinking water. Using a water filter is going to be the safest way to enjoy Dallas tap water.

This will remove many of the contaminants and micro-plastics and will even make your water taste better!

According to water testing, Dallas tap water has a total of 33 contaminants present, after water treatment has occurred. While 21 of the contaminants are only present in detectably small amounts, the other 12 are high enough to exceed health guidelines.

Let’s start by looking at the 12 higher risk contaminants and what they do. The following 11 out of 12 contaminants in Dallas drinking water can increase the risk of cancer.

  • Manganese – While commonly found in water, in high doses exposure can impair the memory and attention span of children.
  • Molybdenum – A natural metal. Frequent exposure could cause gout-like symptoms
  • Nitrate – This fertilizer chemical is a known carcinogen.
