Environmental Monitoring 09/20/16

USEPA issued a modification to the Pompton Lakes Works facility RCRA permit on June 22, 2015 to remove mercury impacted soils and sediment from Pompton Lake. The remedy encompasses four areas consisting of approximately 40 acres. The areas identified in the permit modification include upland soils between Rotary Park and the lake, the lake bottom adjacent to Rotary Park, and the lake bottom at two downstream locations. A map depicting these areas is provided above. A Corrective Measures Implementation (CMI) work plan which describes the means and methods upon which the remedy will be completed was approved by USEPA on April 22, 2016. Field activities associated with the remedy will commence in early June 2016 consisting of the site preparation with soil removal in the upland areas starting in late June 2016. Environmental monitoring of surface water, air, and noise will be conducted in accordance with the CMI work plan during the removal phases of the remediation program.

In reviewing the data, specifically around the elevated reading that occurred at approximately 1500, it appears that there was likely a diesel vehicle or piece of equipment idling in the area of monitoring station AM-3.

There were no dredging or truck loading activities that occurred in the area of this monitoring station during the day.

The local wind during this timeframe was from the southeast (from the lake towards Lakeside Avenue). Therefore, monitoring station AM-3 would have been considered as side gradient.  Stations AM-1 and AM-2 would have been considered downgradient and are both located closer to the dredging operations and truck loading operations for the day.
