If you live in Texas, then you probably know that drinking water quality can vary widely from one part of the Lone Star State to the next. With high concentrations of minerals and other contaminants in the tap water, taking a one-size-fits-all approach to water treatment in Texas isn’t going to provide you with the best possible water.

Whether you get your drinking water from the city water system or drink your own well water, here’s what residents need to know about Texas drinking water quality and how to find the best Texas water filter companies to treat your tap water.

Is It Safe to Drink the Tap Water in Texas?

Texas tap water has a mixed reputation. On the one hand, Texas water companies must adhere to the EPA’s drinking water regulations, just like in any other state. On the other hand, some parts of Texas have high levels of minerals, which can result in hard water that tastes unpleasant and can leave residue on the skin, hair, and other surfaces.

Additionally, even if contaminant levels don’t exceed the EPA’s guidelines, they may still exceed health recommendations. This is especially true for contaminants like PFAS, or forever chemicals, which aren’t thoroughly regulated yet.

What Contaminants Are Found In Texas Tap Water?

Here are a few of the major contaminants to look out for in Texas:

  • Minerals and sediments: Minerals and sediments aren’t necessarily harmful, but can affect how your water tastes. Texas tap water may have high levels of sodium, calcium, magnesium, and other total dissolved solids (TDS).
  • Arsenic and heavy metals: Arsenic and other heavy metals occur naturally in some parts of Texas, and contaminate tap water from groundwater systems.
  • Disinfection byproducts: Disinfection byproducts are chemicals that are formed when tap water is treated with chlorine and other disinfectants.
  • Forever chemicals (PFAS): Forever chemicals are man-made substances used in the production of industrial products. Some municipal water systems in Texas have PFAS levels that exceed the EPA’s new guidelines.
  • Nitrates and nitrites: Nitrates and nitrites can contaminate the water supply in areas with septic systems and fertilizer runoff from agriculture.
  • Viruses and bacteria: Untreated water can harbor cryptosporidium and other pathogens, although these are usually eliminated in the disinfection process.

How Does Texas Water Quality Vary by Region?

As the second-largest state in the U.S., Texas relies on a wide range of water sources to meet its drinking water needs. Although the average hardness is 200 milligrams per liter (mg/L) across the state, no two regions have the same set of water problems.

Here’s how four of the state’s largest cities compare:

Types of Water Filtration Systems

Different types of home water filters are designed to address different water problems, so it’s important to test your tap water and find out what type of filter you need. These are just a few of the most common types of water filter solutions in Texas.

Water Softeners and Conditioners

Water softeners like this Compact Cabinet Water Softener from HomeWater reduce the mineral content of your water by replacing it with sodium ions. This model has a built-in low salt monitor so you know when you need to refill it.

People who need to monitor their salt intake can use this Salt-Free Water Conditioner instead, which removes minerals without adding to the sodium content of the water.

UV Water Systems

UV water filters, like the VIQUA Ultraviolet Light Water Disinfection System, are used to kill viruses and bacteria such as cryptosporidium. Since UV light systems don’t actually filter the water, they’re often used as part of a multi-stage home home water filter.

Reverse Osmosis Water Filters

Reverse osmosis filters like the HomeWater 4-Stage Reverse Osmosis Under Counter Water Filter use reverse osmosis technology to filter your water through a membrane. Since this unit fits under the sink, it’s cheaper and easier to install than a whole home filter, while still removing sediments and chemical contaminants.

Activated Carbon Filters

Activated carbon filters like the HomeWater EZChange Single Stage Under Counter Water Filter are effective at reducing levels of chlorine, lead, PFAS, and other common contaminants. They’re especially good for removing unwanted smells and tastes from your tap water and achieving that pure water taste.
