Standardized Test Method to Quantify Environmental Impacts of Stormwater Pipe Rehabilitation Materials.

摘要

The purpose of this study was to develop a standardized test method that the Virginia Department of Transportation (VDOT) can apply to evaluate the environmental impact of stormwater infrastructure materials. Three laboratory stormwater infrastructure material leaching protocols named static, stirbar, and modified Toxicity Characteristic Leaching Procedure (mTCLP) were developed. These protocols were evaluated for their ability to predict field stormwater quality and aquatic toxicity caused by a pipe rehabilitation material. Cured-in-place pipe (CIPP) was used in this study as a model rehabilitation material because there was prior evidence this technology could cause environmental damage. The study objective was achieved, and during this project it was discovered that the material installation process itself was the main cause of environmental pollution, more than the material. Additional materials and installation processes should be examined in future work.
