Question

True or False?

A decrease in phosphorus load will increase the pollution in surface runoff.   

True or False?

An increase in impervious cover will increase the runoff concentration of pollutants.

Answer 1

Answer)

• A decrease in phosphorus load will increase the pollution in surface runoff is False Statement.

Phosphorus load is directly proportional to the pollution in surface runoff. Phosphorus is a fertilizer and produces very dangerous any harmful toxins to soils in earth surface which shows negative impact on water quality and environment in atmosphere. If we will increase use of phosphorus on earth surface it will results in increase of pollution in surface runoff .Hence the statement is false.

• An increase in impervious cover will increase the runoff concentration of pollutants is true statement.

Impervious cover is a structure or any type of surface which is unable to absorb specially rainfall water like rcc highway roads, parkings, Side walks stones etc. The runoff concentration of pollutants are mainly responsible for water pollution . If we are increasing the impervious cover it increase the runoff concentration of pollutants. Hence the statement is true.
