Where does all the water go? According to the Environmental Protection Agency (EPA), in a typical wetland environment, 39% of the water is outflow; 49% is seepage; 5% 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, 60.4; seepage, 75.0; remaining due to evaporation, 60.4; in the water volume, 33.2.
(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?
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.

Where does all the water go? According to the Environmental Protection Agency (EPA), in a typical wetland environment, 37% of the water is outflow; 47% is seepage; 7% 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.

Question 1 3 pts 1. Where does all the water go? According to the Environmental Protection Agency (EPA), in a typical wetland environment, 45% of the water is outflow; 35% is seepage; 15% evaporates, and 5% remains as water volume 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, 65; seepage. 77; remaining due to evaporation, 40;...
One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. Suppose an EPA chemist tests a 200. mL sample of groundwater known to be contaminated with copper(II) chloride, which would react with silver nitrate solution like this: CuCl2(aq) 2 AgNO3(aq) 2 AgCl(s) + Cu(NO3) ,(aq) The chemist adds 53.0...
