Part II of Fondriest Article Outlining Mussel Importance Released

June 28, 2022

Be sure to check out Part II of Environmental Monitor’s article about endangered mussel surveys by Fondriest Environmental, Inc. featuring EnviroScience Vice President and approved freshwater mussel surveyor Greg Zimmerman, MLS, as well as photo contributions from Becca Winterringer, Phil Mathias, and other ES Marine Services team members.

In the same vein as Part I, Part II does a great job outlining endangered mussel surveys—delving further into why they are necessary, standard procedures and protocols, search methods, equipment, and post-construction monitoring. It even touches on the work EnviroScience performed at Hunter Station Bridge in Pennsylvania—the largest relocation of endangered mussels ever completed in the U.S.! (Over 190,000 mussels were moved to different streams and rivers in various states over two years, earning PennDOT District 1-0 the Pennsylvania Governor’s Award.)
