We regularly receive questions about Brook Run and refer to the project for those municipalities and residents interested in rain gardens. The variety of garden designs and their visibility often provide much-needed education and motivation. Dr. Jay Martin, Professor of Ecological Engineering at The Ohio State University, continues to facilitate water quality tests with students.

Research will be conducted in the area beginning around Veteran’s Day (November 11), and will continue with up to two tests a month for about a year. Past research has demonstrated that the gardens are effective at reductions in stormwater volume, as well as phosphorus and nitrogen levels. This means less streamside erosion, and better water quality for aquatic life. Current testing will evaluate garden effectiveness on hydrocarbons. Hydrocarbons (oil and grease) typically originate from roads, driveways, parking lots, vehicle maintenance areas, gas stations, and illicit dumping to storm drains.

Most Current Brook Run Project Results (Summer 2014)

  • Retained entire runoff volume for 26% of 38 storms
  • Reduced stormwater volume by an overall total of 37%
    • Average volume reduction: 52% peak flow reduction of 62%
    • peak flow delay 16 minutes
  • 50% phosphorus reduction
  • 35% nitrogen reduction
  • 15%+ exfiltration to native soils
