Terrell, Texas's Home for Water Softeners, Water Filters,
& Water Delivery

Terrell’s tap water is treated to meet drinking water requirements, but trace contaminants, chlorine, metals, and treatment-related byproducts can still be present. That is one reason many homeowners choose water filtration for better taste, added confidence, and extra protection at the tap.

Terrell receives water from two main surface water sources. The primary source is Lake Tawakoni, and the secondary source is Lake Lavon. As a purchased-water city, Terrell buys treated water from the North Texas Municipal Water District. Surface water can be affected by runoff, organic material, seasonal changes, and lake conditions, which is why many homeowners choose in-home water testing and filtration.

Terrell reported chlorine as its disinfectant residual, with an average level of 3.27 ppm and a detected range of 1.30 to 4.30 ppm. Chlorine helps control microbes in the water system, but it can also create a chemical taste or smell. A properly selected carbon filtration system can help reduce chlorine taste and odor throughout the home.

Yes. Terrell testing reported Total Haloacetic Acids (HAA5) at 19 ppb and Total Trihalomethanes (TTHM) up to 46 ppb. Individual TTHM sample ranges were reported as high as 67.5 ppb. These byproducts can form when disinfectants react with organic material in surface water, which is why many homeowners choose whole-house carbon filtration for added protection at the tap.

Testing detected nitrate at 0.388 ppm, lead at a 90th percentile level of 2.04 ppb, copper at a 90th percentile level of 0.255 ppm, Total Haloacetic Acids (HAA5) at 19 ppb, and Total Trihalomethanes (TTHM) up to 46 ppb. These results help show why in-home water treatment can still be valuable, especially for homeowners who want more control over their drinking water.

Lead was reported at a 90th percentile level of 2.04 ppb, and copper was reported at a 90th percentile level of 0.255 ppm. The lead range reached 21.2 ppb, and the report listed 1 site over the action level for lead. Because lead and copper can enter water through household plumbing, fixtures, and service lines, homes with older plumbing may benefit from a water test and a drinking water system designed to reduce metals.

Terrell reported nitrate at 0.388 ppm. Nitrate is a contaminant many homeowners pay attention to, especially households with infants, young children, or anyone with specific health concerns. A reverse osmosis drinking water system can help reduce many dissolved contaminants at the tap.

Yes. Terrell’s water quality information listed two violations. One was a Consumer Confidence Rule adequacy, availability, or content violation related to an inadequate Consumer Confidence Report or failure to deliver a CCR certification form to the state on time. The other was a Lead and Copper Rule violation related to lead consumer notice content, delivery, or reporting requirements. Even when a violation is tied to reporting or notification, many homeowners still want extra confidence from in-home testing and filtration.

PFAS test results were not listed in the Terrell water quality information provided. That does not mean homeowners are not concerned about PFAS. Testing requirements and water quality priorities can change, and many families choose advanced filtration, such as reverse osmosis, for added protection against a wider range of potential contaminants.

Hardness levels were not listed in the Terrell water quality information provided. However, surface water can still contain minerals that affect taste, feel, spotting, and buildup around the home. A local water test can show whether a water softener, whole-house filter, reverse osmosis system, or combination system would be the best fit.

Many Terrell homeowners can benefit from a water filter, especially if they want to reduce chlorine taste, disinfection byproducts, lead concerns, nitrate, or issues tied to surface water conditions. A local water test can help determine whether a whole-house filter, reverse osmosis system, water softener, or combination system makes the most sense for your home.
