Skyline of Grand Rapids, Michigan

Burlington, Mass., March 29, 2024 — Sixteen Haley & Aldrich experts will speak at the World of Coal Ash (WOCA) conference on May 13-16 in Grand Rapids, Michigan.  

This conference brings together environmental experts, industry members, and others to share knowledge related to coal ash and other coal combustion residuals (CCR) management, remediation, and compliance. The American Coal Ash Association and the University of Kentucky Center for Applied Energy Research co-host WOCA every other year. 

“It’s rare to get a chance to connect with so many others focused on CCR-related research and problem-solving, from other engineers and scientists to contractors, energy industry representatives, and government representatives,” says Steven Putrich, principal consultant, geoenvironmental engineering and industrial waste management, at Haley & Aldrich. “We look forward to this opportunity to share lessons learned from the projects Haley & Aldrich has managed and to expand our knowledge.”
