In applying equation ( 3) to the Sutey Disposal site , the
following parameter values were assumed :
P = 35 in/year
A = 15. 3 acres (5-year design)
F = 10%
Q = 0. 8 cfs (low flow in Coal Creek)
19 cfs (mean annual flow in Coal Creek)
70 cfs (peak flow in Coal Creek)
16 Cw = 500 mg/1
The value assumed for ACw (500 mg/1) is probably an over-
estimate, leading to conservative (maximum) values in 0 Cs. For
low mean annual , and peak flows in Coal Creek, the estimated
increases in total dissolved solids are as follows :
Low Flow Cs = 3. 8 mg/1
• Mean Annual Flow 0 Cs = 0. 16 mg/1
Peak Flow PCs = 0. 044 mg/1
5. 0 CONCLUSIONS
The above presented evaluation indicates that the impacts of
the Sutey Property disposal site on the ground or surface water
regime are very small . Estimated increases in total dissolved
solids range between 0.044 mg/1 during the peak flow and 3.8 mg/1
during the low flow in Coal Creek.
