FAIRFIELD — The last of PCB-contaminated material has been removed from the town’s fill pile on One Rod Highway, according to the latest update from officials.

According to the report, the last 110 tons were removed and soil samples taken from the “hot spot.”

The contaminated fill was discovered last year, while the pile of construction debris and road-cleaning spoils was being managed by a private firm, Julian Construction. The idea was to have Julian reduce the size of the pile, which has existed for several decades.

Instead, the pile grew and neighbors began to complain. An inspector hired by the town spotted a suspicious load of debris, and testing later showed the existence of low levels of PCBs and lead on a small portion. The fill pile was shut down, and Julian’s contract ended.

The town is preparing a remediation action report that will be submitted to the state Department of Energy and Environmental Protection.

The remediation costs have not exceeded the $289,000 budgeted for that purpose, and the town is in the midst of a court case with Julian, seeking $3 million from the company. Julian has countersued, charging the town with defamation.

A design for the capping of the pile, groundwater monitoring wells and a grading plan is in the process of being revised. The town is expected to develop a five-year plan for the fire training area, the mulch yard and the Public Works yard, all on One Rod Highway.
