Answer:Estimating the average level of nitrogen in the water

Explanation:

The concerned citizens are trying to determine the average level of nitrogen in the water. They collected the samples for a month in order to get the correct average reading of nitrogen.

They might be interested in knowing whether there is excess nitrogen in water or not as excess nitrogen can overstimulate the growth of aquatic plant and algae. Excess growth can, in turn, clog water intakes, use dissolved oxygen, Block sunlight by covering the entire lake.
