Frequent Questions

What research has been done on the impact of pharmaceuticals in drinking water?

There exists an increasing body of literature on the topic of pharmaceuticals, including the detection, prevalence, and persistence of pharmaceuticals in source water and treated drinking water, as well as evaluations of treatment techniques for removal or transformation of these compounds. Many studies have reported on the presence of pharmaceuticals in treated drinking water, suggesting that some compounds are resistant to certain treatment technologies. Despite being detected in low levels, below therapeutic doses, research is still being conducted to determine whether long term low-level exposures to pharmaceuticals adversely affect the human general population Please visit EPA’s website (listed below) on research related to pharmaceuticals for an overview, frequently-asked questions, and current research areas.
