Question

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; in the water volume, 70. Compute the weighted average. Round your answer to one decimal place. 68.9 O 65.7 O 62.4 O 71.23

Answer 1

Calculation: (0.45X65+0.35x77+0.15x40+0.05x7 0)/(0.45+0.35+0.15+0.05) = 65.7

65.7
