Dallas Compounds of Emerging Concern Study

Science Center Objects

Pharmaceuticals and personal care products (PPCPs), as environmental contaminants, are a source of increasing concern because of their possible disruption of endocrine systems in humans and other organisms. The USGS Texas Water Science Center is collecting and analyzing samples from inflows and outflows of five Dallas water treatment plants and five sites in the Trinity River for pharmaceuticals and other compounds of emerging concern.

The first objective of this study is to determine the occurrence, distribution, and concentration of pharmaceutical compounds and personal care products in sources of potable water for the City of Dallas (pre-treatment and post-treatment), in untreated and treated wastewater and biosolids at wastewater treatment plants, and the fate and transport of pharmaceuticals and personal care products in the Trinity River from Dallas downstream to Trinidad, TX.

Following data collection, this study will provide the following analyses:

  • The occurrence, distribution, and concentration of pharmaceutical compounds and personal care products in sources of potable water for the City of Dallas (pre-treatment and post-treatment);
  • The occurrence, distribution, and concentration of pharmaceutical compounds and personal care products in untreated and treated wastewater at wastewater treatment plants;
  • The fate and transport of pharmaceutical compounds and personal care products in the Trinity River from Dallas downstream to Trinidad, TX.
