Tafuri, A., L. Talebi, AND R. Pitt. Chemical and Microbiological Quality of Runoff Into and Out of Dry Wells; A Case Study in Millburn, NJ. In Proceedings, WEFTEC 2012, September 29 - October 03, 2012. Water Environment Federation, Alexandria, VA, 1-0, (2012).
Abstract Since 1999, the city of Millburn has required dry wells to accommodate additional flows from newly developed areas. This new requirement to divert the increased roof and impervious surfaces runoff to dry wells was established to mitigate local drainage and water quality problems. One component of this EPA-funded project involved monitoring stormwater flows from individual properties to the dry wells and associated subsurface waters in the soil beneath the dry wells. Bacterial and chemical water quality was measured during ten rain events in three different dry wells and at one water storage cistern location. Findings indicated that the dry wells did not significantly change any of the water quality concentrations for the observed stormwater constituents. The cistern system did result in significant reductions in bacteria levels.
The overall objective of the EPA project was to investigate the hydraulic performance and water quality changes associated with the dry well operations. The majority of the dry wells examined received runoff from roofs, while some also received runoff from surrounding paved driveways, parking areas, and landscaped areas. This paper is mostly excerpted from the recent EPA report: Evaluation and Demonstration of Stormwater Dry Wells and Cisterns in Milburn Township, New Jersey (Pitt and Talebi 2012).
