Because removal of dissolved P by sand filters tends to be negligible, the dissolved P load reductions observed at both sites are likely attributable to the DWTRs. Overall, the two systems reduced total P loads by 65-78% during the monitored events. This field study indicates that including DWTRs in sand filter media is an effective way to couple both physical and chemical P removal mechanisms and thereby enhance water quality improvement performance. The researchers provide guidance on future use of DWTRs in stormwater infrastructure based on our findings. The researchers also present stormwater chloride data from the monitored events, which can be used in future efforts to assess road salt effects on stormwater characteristics in Vermont.]]> Wed, 09 Oct 2024 11:48:30 GMT https://rip.trb.org/View/2437970 https://rip.trb.org/View/1757057 Thu, 10 Dec 2020 16:27:00 GMT https://rip.trb.org/View/1757057 https://rip.trb.org/View/1234789 Thu, 03 Jan 2013 15:19:22 GMT https://rip.trb.org/View/1234789
