A nearly $3 million contract was awarded to a Wantagh firm Tuesday by the Islip Town Board to clean up an estimated 50,000 tons of contaminated debris illegally dumped in a town-owned park.

Gramercy Group Inc. was selected from a list of six qualified bidders to complete the project at Roberto Clemente Park on a bid of $2,992,240. Dozens of companies were initially interested in the cleanup job but either did not submit bids or were disqualified for various reasons. Bids were publicly opened March 26.

Gramercy was the lowest bidder, while the highest came in at $5.7 million.

Vincent Parziale, president and owner of Gramercy Group Inc., said his company has been doing similar cleanup work since 1999. He said he did not foresee any unusual issues with the project, but said the main issue will be dust control.

"It's a pretty cut and dried job," Parziale said. "This is what we do. It'll be done professionally and properly. We respect the community and we'll make sure we're keeping them safe."

Islip Town Supervisor Angie Carpenter called the vetting on each prospective bidder by the town "thorough and diligent," a process that included more than 35 areas of scrutiny, such as past business practices, operational performance and environmental safety records.

Enviroscience Consultants Inc. of Ronkonkoma was awarded a separate contract -- not to exceed $400,000 -- to monitor the air quality and for inspection during the remediation. Enviroscience has been working with the town since May after the park was shuttered a year ago following the start of Suffolk County District Attorney Thomas Spota's probe that revealed contamination in the debris.

Both resolutions passed unanimously, 5-0.

Work will take about four months to complete and is expected to begin in June, Carpenter has said. The town board last year passed a resolution authorizing $6 million in bonds to pay for the cleanup and reconstruction of the park, but the bonds have not yet been put out for sale, Islip Comptroller Joseph Ludwig said Tuesday.

Spota's investigation last year into illegal dumping began at Clemente Park in April and spread to three other sites in and around Islip Town. Six men, including two former town parks officials, as well as four companies were indicted in December for crimes related to the dumping.
