Given Erin Brockovich’s recent attack on the North Texas Municipal Water District (NTMWD), residents of North Texas have been looking for ways to improve the quality of their drinking water. We’ll start with some background before we dive into a potential solution to the drinking water quality issues raised by Brockovich.


In early March of 2018, Brockovich blasted NTMWD for their explanation of the announced 30-day system maintenance process. She explains in a Facebook post that this “maintenance” is a procedure in which ammonia is removed from the treatment process in order to mitigate the effects of nitrification. According to Brockovich, the fact that nitrification is occurring is proof that the NTMWD is using chloramine, which is a disinfectant used to mask the presence of dirt in the water.

She makes a strong case, because, as she points out, “Nitrification only occurs in systems that are adding ammonia to form chloramine.”

The recommended (but not legally required) method for reducing dirt in the water supply is dirt removal. But NTWMD is using chloramine. Beyond leaving behind a strong chlorinated odor, chloramine can cause mold growth and increase the potential for lead to leach from old pipes.

Sustainably Improving the Quality of Drinking Water with Reverse Osmosis (RO)

Due to the technical nature of this problem, residents of North Texas may be left with more questions than answers.

Fortunately, cleaning your drinking water doesn’t have to be prohibitively expensive or difficult. While there is no silver bullet that will guarantee that 100% of contaminants are removed from your water, a reverse osmosis (RO) filtration system can get you much closer to cleaner, safer drinking water.

For North Texas residents, Horizon Plumbing recommends an RO system like the Nimbus WaterMaker Five which allows you to address many of the specific health threats posed by North Texas’s water treatment process. This system mitigates the effects of both chloramine and chlorine, two of the cleaning agents currently in use by the NTMWD. Using this system will help ensure that your drinking water is within the EPA’s recommended range for contaminants.

And because of this system’s unique design, it cleans your water without wasting it, as many other reverse osmosis systems do. In fact, the Nimbus system loses only one gallon of water per one gallon filtered. Compared to the average system that wastes about five gallons per one gallon filtered, the Nimbus RO system provides a more sustainable way to access clean drinking water inside your home.

Getting Rid of the Chlorine Smell and Improving Taste

 According to the EPA, copper and total dissolved solids, among other chemicals, negatively impact the look, smell and taste of drinking water. On average, the WaterMaker Five RO system reduces the presence of copper by 98.4% and total dissolved solids by 93.1%. Moreover, this system has been certified to NSF/ANSI Standard 58 for reducing copper and total dissolved solids.

Improving the Safety of Your Water

 At this point, it’s hard to pinpoint what contaminants might be present in the water supply treated by the NTMWD. The Nimbus WaterMaker Five can provide additional peace of mind, though, because it is also certified to reduce several contaminants to the levels required by the EPA. A full list of contaminants and their acceptable levels can be found on the EPA website.

13 of the water contaminants identified by the EPA can be reduced or nearly eliminated by the Nimbus WaterMaker Five. The level of average reduction for these 13 contaminants ranges from 93 to 99.9%.

Also worth noting is this system’s proven ability to remove pentavalent arsenic from your drinking supply. Arsenic poses a serious threat to your long-term health, but the Nimbus system removes, on average, 99.9% of pentavalent arsenic. However, the Nimbus system will not remove trivalent arsenic.
