According to the Environmental Protection Agency (EPA), in a typical wetland environment, 36% of the water is outflow; 47% is seepage; 8% evaporates; and 9% remains as water volume in the ecosystem (Reference: United States Environmental Protection Agency Case Studies Report 832-R-93-005). Chloride compounds as residuals from residential areas are a problem for wetlands.
Suppose that in a particular wetland environment the following concentrations (mg/l) of chloride compounds were found:
outflow, 53.6; seepage, 73.9; remaining due to evaporation, 57.0; in the water volume, 74.0.
(a) Compute the weighted average of chlorine compound concentration (mg/l) for this ecological system. (Round your answer to one decimal place.)
