Today’s Guests:
On this episode of Water Talk, Paul “The Waterman” Dowding, Owner of Water Pros focused on a growing concern in America’s drinking water: pharmaceuticals that may be present in source water, groundwater, surface water, and even treated drinking water. The discussion centered around new information from the U.S. Environmental Protection Agency, which, in coordination with federal partners including the USDA, FDA, and USGS, released updated Human Health Benchmarks for Pharmaceuticals in April 2026.

These benchmarks do not necessarily mean every community has these drugs in its water, but they do show that the EPA is paying attention to the issue. The agency evaluated 374 FDA-approved pharmaceutical ingredients that may occur in water and developed benchmark levels for both the general population and infants. Those separate infant benchmarks are especially important because babies and young children may be more vulnerable to even very low levels of exposure.

Paul explained that pharmaceuticals can enter the water supply in several ways. Medications may pass through the body and into wastewater, be improperly flushed or discarded, or enter the environment through medical, agricultural, or household use. Traditional municipal water treatment is designed to make water legally safe from bacteria and many regulated contaminants, but it may not remove every trace pharmaceutical, hormone, chemical, or emerging contaminant.

The key takeaway from the interview was not fear, but awareness. Many of these substances may be found only at very low levels, and the EPA’s benchmarks are meant to help water systems, scientists, and public health officials evaluate potential risk. However, Paul emphasized that “legal” water and “optimal” water are not always the same thing. Families who want greater confidence in what they are drinking should understand what is in their local water and consider additional in-home filtration when appropriate.

As always on Water Talk, Paul’s message was education first. The more consumers understand about pharmaceuticals, PFAS, microplastics, and other emerging contaminants, the better decisions they can make for their home, their health, and their water.
