Water Treatment Systems

Nashua River Asbestos Site Water Treatment System
Maxymillian Technologies treated contaminated water from a 600-foot portion of the Nashua River. Overall site cleanup included river excavation, water treatment, and riverbank restoration. Maxymillian Technologies' scope of work involved mobilizing a MT designed and operated Water Treatment System to conduct full-scale treatment operations.

Maxymillian Technologies' water treatment and discharge system treated sediment-laden, asbestos-and coal tar-contaminated water obtained from dewatering an excavation at a continuous rate of 500 gallons per minute (GPM), 24 hours per day.

Following treatment, the water was sampled and analyzed to ensure that treatment standards were met. Maxymillian Technologies interfaced with regulatory officials to attain a NPDES Exclusion Permit to discharge treated water back into the Nashua River.

The final stage of the project involved removing spent filter media, piping, frac tanks, and solids/sludges. This was followed by the decontamination of the entire treatment system and related materials, and demobilization.

Maxymillian Technologies' water treatment operations supported the combined efforts of the USEPA, the US Army Corps of Engineers, and other New England Remedial Action Contract Team members, to restore the environmental integrity of a section of the Nashua River.

"Maxymillian Technologies had the additional burden of maintaining the on-site water treatment system on a 24 hour/day schedule. They were always able to perform their work in a highly efficient and safety conscious manner despite these challenges. Maxymillian's seamless operation and maintenance of the water treatment system played a major role in the timely completion of the project." -Mr. James Morocco, USACE
