Review of common construction practice finds environmental contamination, need for improved oversight and monitoring
An in-depth review of environmental protections for a common storm water culvert repair practice — cured-in-place pipe repair, or CIPP — has revealed differing installation practices across states, water contamination incidents in 10 states and Canada, and lack of safety data for existing installation practices. Funded by six states, Purdue University researchers examined past water contamination incidents, environmental studies, industry practices and construction specifications from 32 states.
