Math Problem Statement
According to the 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. (EPA 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.
Find the mean chlorine compound concentration (mg/l) for this ecological system.
State the answer only and no additional work. Do not label the answer.
Do not round the final answer.
Hint: Find the weighted mean.

Here are 5 related questions you might explore:
- How would the weighted mean change if the concentration of chloride in seepage increased?
- Can you compare the weighted mean with an arithmetic mean for this set of data?
- How does seepage impact the mean concentration compared to evaporation?
- What is the significance of weighted means in environmental studies?
- How could reducing chloride in outflow improve the overall ecosystem health?
Tip: Weighted means are useful when different components have varying levels of influence on a system, like water flows in wetlands.
