Problems We Found In St. Louis Drinking Water

For Hydroviv’s assessment of St. Louis’s drinking and tap water, we collected water quality test data from St. Louis and the U.S. Environmental Protection Agency. We cross referenced St. Louis water quality data with toxicity studies in scientific and medical literature. The water filters that we sell at Hydroviv are optimized to filter out contaminants that are found in St. Louis’s drinking water.

Where Does St. Louis Source Its Drinking Water?

St. Louis sources its drinking and tap water from the Missouri and Mississippi Rivers.

St. Louis Disinfects Its Water With Chloramine 

While most municipalities use chlorine as the primary drinking water disinfectant, St. Louis disinfects its drinking water with chloramine. Chloramine is primarily responsible for what many customers report as the “bad taste” or “pool smell” of tap water. Concentrations were detected as high as 3.36 parts per million in treated water, which is just under the EPA Maximum Contaminant Level of 4 parts per million. Unlike chlorine, chloramine does not dissipate if a container of water is left in the refrigerator overnight. Most one-size-fits-all water filters use filtration media that doesn’t do a great job removing chloramine, but the filters that we design and build at Hydroviv for St. Louis use a special filtration media that is purposefully designed to remove chloramine.

It’s important to note that only a handful of contaminants are required to be included in annual Consumer Confidence Reports, and that there are hundreds of potentially harmful unregulated contaminants that aren’t accounted for.
