Mercury in Wastewater Investigation – Confidential Manufacturing Facilities – Eastern and Southwestern, Ohio

STONE was contracted by separate entities in eastern and southwestern Ohio to sample wastewater to determine the presence and possible sources of mercury which caused the discharges from each company to exceed allowable local limits. Composite sampling of process wastewater was performed at one location, while grab samples were collected at another location. Samples were analyzed using USEPA approved low-level mercury analytical methods. At one location, the results were used to justify that the facility was not a major mercury discharger to the local wastewater treatment facility. The other testing was used to determine whether the mercury entering the wastewater resulted from in-plant sources.

“STONE is an instrumental part of our team on the Portsmouth By-Pass Project: the 16-mile new construction project, which is the single largest project in ODOT history. This project has come with more than its share of environmental challenges. STONE has delivered over 30 full environmental clearance reviews and reports we have requested as part of the project, handling them from start to finish in a very timely & cost effective manner. Furthermore, they’ve proven themselves as an extremely valuable resource when it comes to consulting on mitigation efforts, hazardous materials, and resolving various unknown environmental situations that the project has encountered.

 

From the top down STONE has proven they are committed to excellence and we look forward to working with them on many projects in the future.”
