Coal Ash Pond Remediation: ELG and CCR


GWTT Understands the Challenges of ELG and CCR Remediation

Effluent Limitation Guidelines (ELG) – As a company that is technology agnostic, we have access to many different applications and technologies that focus on satisfying the discharge requirements for waste streams from flue gas desulfurization (FGD) effluent, landfill and leachate collection systems, and other waste wat
Periodic-Tableers covered under the EPA’s Effluent Limitation Guidelines, the NPDES, or other permit programs.

Coal Combustion Residuals (CCR) Pond Remediation – We have experience treating nearly 400 million gallons of CCR pond water (bulk surface water and the interstitial “pore” water) with custom-designed treatment systems specific for total metals, with a focus on the reduction of arsenic and selenium (which are difficult to treat with traditional water treatment techniques) for the required effluent discharge criteria.


GWTT Offers a Total SolutionSystem-Model

Unlike many of our competitors, we offer a truly turn-key, holistic approach to solve the problems of ELG compliance and coal ash pond/CCR remediation. GWTT takes the lead on all aspects of the challenges posed by coal ash ponds, starting with source water characterization and treatability studies; throu
gh the design and construction of a custom-tailored treatments system; complete operation and maintenance of the customized system; as well as ongoing compliance testing and monitoring.

GWTT will be your single point of contact and act as program manager throughout the project, from the first water chemistry assessment through project site demobilization.

We provide the high-level project and program management required for consistent and efficient operations and ultimate project success.
