<br />RESULTS
<br />
<br />The results of the data collected and compiled
<br />during this study are presented in the "Water-Quality
<br />Data" section at the back of this report. Onsite mea-
<br />surements, bacteriological data at selected stations, and
<br />selected inorganic data for all stations sampled during
<br />the study are listed in tables 2--{,O. Selected surface-
<br />water stations with pesticide data are listed in table 61;
<br />selected stations with radiochemical data are listcd
<br />in table 62; and selected stations with suspended-
<br />sediment data are listed in table 63. Results offield-
<br />collected quality-assurance data for the purpose of
<br />assessing potential sample contamination are listed in
<br />tablcs 64 and 65.
