Description

The growth medium of a green roof is likely to affect the chemistry of the rainwater passing through it, which may impact the receiving waters. Currently only limited data exist on the changes in rain chemistry caused by green roofs. The objectives of this project are to determine the differences in concentration of several contaminants in rain and in runoff from a green roof in downtown Syracuse, NY, and to explore reasons for the observed differences. A few samples were collected in 2014 and 2016, but most of the data are from 2017. Collection of precipitation uses funnels, while collection of runoff takes place using a drainpipe that connects to several roof drains. Both types of samples are analyzed by ion chromatography for chloride, sulfate, and nitrate. Preliminary tests show that chloride concentrations in the green roof runoff are generally greater than or equal to those in precipitation. Sulfate in the runoff is greatly enhanced compared with precipitation. Nitrate concentrations do not show a clear pattern. Engineered soil greatly influences the chemistry of the incoming rain, and additional research is needed to better understand this chemistry.

Chemical Analysis of Precipitation and Stormwater Runoff from a Large Green Roof

The growth medium of a green roof is likely to affect the chemistry of the rainwater passing through it, which may impact the receiving waters.
