these differences is a mix-up in reporting TSS and TDS values. <br />F. TSS at station 306 dropped from a baseline value of 320 <br />mg/L to a 1995 range of <5 - 100 mq/L in 1995. Once again a <br />possible explanation for this rise is a mix-up at between TSS <br />and TDS values. <br />G. Sulfate at station 306 rose from 6 mq/L to a 1995 range of <br />170 - 1870 mq/L. This is a very sharp increase. <br />H. Sodium rose at station 306 from 3 mg/L to a range of 77.3 <br />- 722 mg/L. It appears that surface water station 306 was <br />affected a lot by mining or another source of disruption. <br />I. Aluminum at station 306 dropped from a high baseline level <br />of 9.7 mg/L to a current level of .22 mq/L. <br />J. Electrical conductivity had a sharp drop at station AP-2 <br />from 1303.3 umho/cm to 567 umho/cm. <br />R. Heavy minerals such as; A1, Ba, B, Cd, Cr, Cu, Pb, and Hg <br />all had a drop at station AP-2 from levels that were in the <br />tenths (. 1) to levels that are in hundredths (.01) and <br />thousandths (.001). <br />
