Why is there a need to monitor storm water runoff?
• Storm water runoff has a major impact on water quality
• Storm water permits were developed so that industrial operations could be proactive
• Management of controls at the facilities effects the quality of the runoff
• Without monitoring we don’t know the quality of the runoff
