urface water can become contaminated in many ways.Surface water can be contaminated when hazardous substances are discharged directly from an outfall pipe or channel or when they receive contaminated storm water runoff.Direct discharges can come from industrial sources or from certain older sewer systems that overflow during wet weather.Storm water runoff becomes contaminated when rain water comes into contact with contaminated soil and either dissolves the contamination or carries contaminated soil particles.Surface water can also be contaminated when contaminated groundwater reaches the surface through a spring,or when contaminants in the air are deposited on the surface waterSurface water can also be contaminated when contaminated groundwater reaches the surface through a spring,or when contaminants in the air are deposited on the surface water.Contaminated soil particles carried by storm water runoff or contaminants from the air can sink to the bottom of a surface water body,mix with the sediment,and remain.
