Abstract
The discharge-weighted average concentrations of dissolved solids, chloride, and ,sulfate for many of the principal streams in Texas are less than 500 mg/l (millijgraljls per liter), 250 mg/l, and 250 mg/l, respectively. At 65 of 131 sites on streams that were sampled at least 10 times, the biochemical oxygen demand of at least half the samples exceeded 3.0 mg/l. At 20 of the sites, the dissolved-oxygen content of at least half the samples was less than 5.0 mg/l. The higher concentrations of minor elements usually were detected in waters from urban areas, indicating a relation to man's activities. Small amounts of some pesticides are widely distributed in low concentrations. The higher concentrations usually were detected in waters from urban areas.
