Concentrations of dissolved organic nitrogen and phosphorus for sites 1-6, water years <br />1987-68. <br /> <br />Trace Constituents <br /> <br />Data' for dissolved and total or total recoverable <br />concentrations of 27 trace constituents analyzed from <br />water samples collected intermittently at sites 1-6 were <br />compiled for water years 1975-88. Data were unavail- <br />able for concentrations of bromide, hexavalent chro- <br />mium, iodide, and thallium; and concentrations oftotal <br />cyanide in 29 water samples from sites 1-6 were less <br />than 0.01 mg/L. No additional analyses of the above <br />five constituents were done. Data also were unavail- <br />able for total recoverable boron and vanadium. <br /> <br />Ranges for the remaining 22 trace constituents <br />are listed in table II. Data from filtered water samples <br />were grouped by site, and concentration distributions <br />are shown as dissolved concentrations in figure 27. <br />Total or total recoverable concentrations (hereinafter <br />referred to'as total), determined from unfiltered water <br /> <br />samples, were grouped by site, and concentration dis- <br />tributions are shown in figure 28, Although the data <br />were sparse at some sites and many concentrations <br />were reported as less than values, the concentrations of <br />trace constituents in the White River are summarized as <br />follows: <br /> <br />1. Dissolved and total concentrations of 15 trace <br />constituents (aluminum, arsenic, barium, <br />boron, copper, iron, lead, lithium, manganese, <br />molybdenum, nickel, selenium, strontium, <br />vanadium, and zinc) commonly were detected <br />in the White River, All concentrations of <br />arsenic and selenium were equal to or less than <br />5 Ilg/L, and the concentration range for dis- <br />solved manganese (5-70 IlgIL) at site 4 was <br />unexplainably large when compared with <br />manganese concentrations (generally less than <br />20 IlgIL) at sites 1-3,5, and 6. <br /> <br />54 Sediment Transport and Wster-Quellly Charecterlstlcs and LoadS, White River, Northwestern Colorado, Water Years <br />1975-88 <br />
