Question
Where does all the water go? According to the Environmental Protection Agency (EPA), in a typical wetland environment, 36% of the water is outflow; 49% is seepage; 8% evaporates; and 7% 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, 74.0; seepage, 74.1; remaining due to evaporation, 57.0; in the water volume, 75.7.

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