MERCURY REMEDIATION AT MANUFACTURE OF HYDROELECTRIC TURBINES

Serving Georgia, Tennessee, Alabama, North Carolina, South Carolina, and Florida

Location: Confidential

Client: Manufacture of Hydroelectric Turbines

Contract Amount: $412,000


PROBLEM


Remtech Engineers was engaged by one of the largest hydroelectric turbine manufactures to investigate, provide emergency PPE and decontamination procedures, and remediate a production facility mercury release.  Mercury was found on concrete and metal surfaces.  The source of mercury was due to failure of a bearing in the hydraulic reactor loop and test lab. Remedial measures included draining and cleaning the reactor and reservoir, cleaning floors under the test loop, elemental mercury recovery from tanks, test loop, and production equipment components.
