Are these chemicals in my drinking water?
This study was not designed to determine the levels of these compounds
in drinking water (although some streams sampled are used as sources
of drinking water), or to determine the efficiency of various drinking-water
treatment technologies. However, given that these types of compounds
are being transported to streams, it is certainly possible that low
levels of some compounds could be present in some drinking-water sources
(in streams where water is removed fro drinking water purposes). These
waters then typically undergo a variety of treatments before they reach
our tap. And, although the treatment processes were not designed to
remove most of these compounds, some may be removed or reduced.
The USGS Toxic Substances Hydrology Program is conducting a survey
of source waters in collaboration with the U.S Environmental Protection
Agency. Stay tuned to this web
