• 5.0 SURFACE-WATER QUALITY <br />Samples were collected from sites S1, S3, 001, 002, 005, 006 and <br />008 during the 1987 mine year. Results of the analyses performed on <br />these samples is presented in Table C-1. The more frequently measured <br />parameters are presented in the first seven pages with the annually <br />measured parameters on the last pages. <br />5.1 TSS <br />Figures C-6, C-8, C-10, C-12, C-14, C-16 and C-18 present plots <br />of Total Suspended Solids (TSS) versus time for the sites S1, S3, 001, <br />002, 005, 006 and 008, respectively. Plots of flow versus TSS are <br />presented in Figures C-7, C-9, C-11, C-13, C-15, C-17 and C-19. <br />Figure C-6 presents TSS versus time for site S1. TSS values were <br />• generally below 100 mg/1 except for the high flow period of early <br />March when 344 mg/1 TSS was measured. Figure C-7 shows that the 1987 <br />TSS data did not relate well to flow due to the small flow values <br />observed. <br />Figure C-8 exhibits TSS values typically lower than 50 mg/1 <br />during most of the year. Much higher TSS values of 766 and 21,900 <br />mg/1 were seen early in the year corresponding to higher flow periods <br />as seen in Figure C-9. A fair TSS-discharge relationship could <br />probably be obtained by using the two large values and the remainder <br />of the values as one data point. <br />Sites 001, 002 and 005 were normally observed to have TSS values <br />below 50 mg/1 during the 1987 mine year. These values did not <br />differentiate much from past values preser:t Ed on rigures C-10, C-12 <br />. and C-14, respectively. The flow versus TSS relationships are <br />presented in Figures C-11, C-13 and C-15. These three plots show a <br />5-1 <br />
