28. EPA: Wetlands Where does all the water go? According to the Environmental Protection Agency (EPA), in a typical wetland environment, 38% of the water is outflow; 47% is seepage; 7% evaporates; and 8% remains as water volume in the ecosystem (Reference: U.S. 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, 64.1; seepage, 75.8; remaining due to evaporation, 23.9; in the water volume, 68.2. a. Compute the weighted average of chlorine compound concentration (mg/L) for this ecological system. b. Suppose the EPA has established an average chlorine compound concentration target of no more than 58 mg/L comment on whether this wetlands system meets the target standard for chlorine compound concentration.

28. EPA: Wetlands Where does all the water go? According to the Environmental Protection Agency (EPA), in a typical wetland environment, 38% of the water is outflow; 47% is seepage; 7%
evaporates; and 8% remains as water volume in the ecosystem (Reference: U.S. 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, 64.1; seepage, 75.8; remaining due to evaporation, 23.9; in the water volume, 68.2.
a. Compute the weighted average of chlorine compound concentration (mg/L) for this ecological system.
b. Suppose the EPA has established an average chlorine compound concentration target of no more than 58 mg/L comment on whether this wetlands system meets the target standard for chlorine compound concentration.
