Copper Corrosion Assessment – Marysville Exempted Village Schools – Marysville, Ohio

STONE was contracted to assess a copper corrosion problem at an Elementary School. The school served a population of 310 students and faculty and obtained potable water from on-site groundwater wells. Raw water treatment consisted of sand filters, ion exchange softening, and chlorine disinfection. Routine water testing detected copper concentrations at elevated levels. STONE designed a system to feed zinc orthophosphate into the potable water system to reduce the copper concentrations to allowable levels.

Detailed plans showing the layout of the existing system were prepared by STONE and the proposed chemical feed and mixing equipment selected, designed, and specified. The Ohio EPA Water Supply Data Sheet was prepared and submitted to Ohio EPA. Ohio EPA’s Central District Office approved the plans. The system was installed to abate the high copper concentrations found in the system.

“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.”
