Answer to Question 1
Answer: Since water is the universal solvent, it is used in industrial, commercial, agricultural and residential operations. Through this use, the water incorporates contaminants and transports them downstream. There are two types of pollution sources, point and non-point. Point pollution is where the water exits a known location such as a pipe. Filters and sieves can be applied to these locations to remove most pollutants. Non-point pollution locations are more difficult as these have no specific place to intercept the contaminants, such as water running off a farm field. The planting of vegetative buffers or development of man-made wetlands have been used to intercept pollutants from these sources.
Answer to Question 2
Answer: Pollution prevention means not producing pollutants: pollution control means removing them from waste before discharging the waste to the environment.
