natural ranges but some increase over baseline has likely occurred at NPDES sites 001 and <br /> 011. No long-term trends are indicated by the major constituents except for NPDES site <br /> 001, which is presently increasing with time. <br /> 5.3 OTHER CONSTITUENTS <br /> Field pH values for all sites were very similar in 1999 to previous data. Values <br /> typically ranged from near neutral to 9 for pH values at NPDES site 001. Other <br /> constituents analyzed showed little change with all minor constituents within their natural <br /> ranges. All values addressed in this report above permitted discharge levels have been <br /> addressed in the quarterly NPDES discharge reports (DMR's) and justifications for those <br /> values, i.e. storm water, snow cover melt-out, etc., have been submitted to the proper <br /> regulatory authorities. The iron concentrations observed in 1999 in the surface water for <br /> this readily available constituent were lower than normal due to the low flow rates. <br /> 5-3 <br />
