According to the Enviornmental Protection Agencey (EPA), in a typical wetland enviornment, 38% of the water is outflow, 47% is seepage, 7% evaporates, and 8% remains as water volumes in the ecosystem. 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; remainging due to evaporation, 23.9; in the water volume 68.2
a) Compute the weighted average of chlorinie compound concentrations (mg/l) for this ecological system.
b) Suppose the EPA has established an average chlorine compound concentration target of no more than 58mg/l. Comment on whether this wetlands system meets the target standard for chlorine compound concentration.
