Question

Where does all the water go? According to the Environmental Protection Agency (EPA), in a typical wetland environment, 37% of the water is outflow; 49% is seepage; 6% evaporates; and 8%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, 60.4; seepage, 74.8; remaining due to evaporation, 51.9; in the water volume, 55.3.

(a) Compute the weighted average of chlorine compound concentration (mg/l) for this ecological system. (Round your answer to one decimal place.)
mg/l

(b) Suppose the EPA has established an average chlorine compound concentration target of no more than 58 mg/l. Does this wetlands system meet the target standard for chlorine compound concentration?

Yes. The average chlorine compound concentration (mg/l) is too high.Yes. The average chlorine compound concentration (mg/l) is lower than the target.     No. The average chlorine compound concentration (mg/l) is lower than the target.No. The average chlorine compound concentration (mg/l) is too high.
