VOC Mission Statement

Volatile organic compounds VOCs are produced in large volumes and are of concern in water resources because of their potential toxicity to humans, in part via exposure from drinking water. The general purpose of the VOC National Synthesis of the NAWQA Program is to expand knowledge about the occurrence of this group of organic compounds in the environment with emphasis on ground water, surface water, and water withdrawn for supply of drinking water. The synthesis is unique in that its focus is on ambient water resources rather than extensively contaminated release sites. Furthermore, the synthesis fills important voids of information about VOCs for the Nation's major aquifers and urban streams.

The intent of this web site is for interested persons to easily access information about VOCs such as data sets, publications on various topics, answers to frequently asked questions, and so forth. Ideas to further improve the utility of the web site are always greatly appreciated!

Thanks in advance for your interest in our assessment!
