seasons collected at both SW N1 and SW-N3 (1980 through 1987), it was concluded that flow had <br />little correlation with TDS. <br />Finally, TSS did not correlated with TDS. A negative value for the correlation coefficient (r2 ) that <br />approaches 1.0 (>.750) would indicate that TDS is inversely related to TSS. For each site during <br />both seasons, the correlation coefficient determined using the simple regression and correlation <br />technique were not negative as expected, never exceeded .600, and ranged from .007 (SW-NI, <br />irrigation season) up to .593 (SW-N6, non-irrigation season). <br />Based on the aforementioned results, it was concluded that discharge (flow) had no relationship <br />with TSS. It should be noted that TSS values were determined by an outside laboratory using a <br />small yet proportionally divided portion of each water sample taken at each site. However, <br />considering the magnitudes of TSS determined for sites at the New Horizon 2 mining area (10 to <br />100 mg/1), the laboratory analyses were well within reason. <br />Discharge probably had some influence (relationship) on TDS concentration, but the regression <br />analyses for all sites during both seasons indicated that the relationship was inconsistent and still <br />inconclusive. Finally, there appeared to be no relationship between TSS and TDS. TSS values <br />have only occasionally exceeded 500 mg/I at any monitored site, likely resulting in very few <br />instances where the suspended solids in the flow influence TDS by adsorbing ions and reducing <br />the dissolved chemical load. <br />Surface Water Suitability <br />This section discusses the suitability, present use and potential use of surface water monitored at <br />stream sites at the New Horizon 2 mining area. The suitability of surface water is discussed by <br />comparing historical water quality data for each site with the most stringent state or federal <br />standards established for: 1) drinking water; 2) agricultural water; and 3) livestock drinking water. <br />Also, surface water is discussed in relation to receiving stream standards applicable to the San <br />Miguel River as adopted by the Colorado Department of Health (CDOH, 1983 revised, 1986). <br />Surface water use, both present and potential, is described in relation to each water standard <br />category. <br />2.04.7-45
