The summary of compound detections section in pdf format (print quality). The pdf version of this section is approximately 1.23 KB.


The following tables summarize data collected for NAWQA studies from 1992-95 by showing results for the Trinity River Basin Study Unit compared to the NAWQA national range for each compound detected. The data were collected at a wide variety of places and times. In order to represent the wide concentration ranges observed among Study Units, logarithmic scales are used to emphasize the general magnitude of concentrations (such as 10, 100, or 1,000), rather than the precise number. The complete dataset used to construct these tables is available upon request.
