Versar has been at the cutting edge for over ten years, developing storm water-related pollution prevention plans for a variety of public and private clients. We also have extensive experience in evaluating non-point source/storm water best management practices (BMPs). Reduction of storm water flow into point source discharges though the use of BMPs is one of the key components of our storm water pollution prevention plans for individual permits, as well as for group and general permits. Versar has also developed storm water control mechanisms, field tested them and provided technical guidance on behalf of federal and state agencies. Versar has designed and implemented long-term monitoring programs for permit discharge characterization requirements, involving chemical storm and baseflow sampling as well as biological and physical stream monitoring techniques. Selected Projects: Inspection of stormwater management facility and observation of sediment and erosion problems that are likely to affect the receiving stream.
