Brian Nearing reports in the Albany Times Union that the BASF Corp. will begin cleaning dangerous chemicals out of the Hudson River this fall. The company will begin a $41 million dredging project near a former Rensselaer dye factory installing a steel bulkhead to strengthen a seawall near Riverside Avenue. They will remove PCBs, volatile organics, and toxic heavy metals such as lead, cadmium, copper, mercury, zinc, and arsenic, that got into the river from production sewer and storm water discharge pipes. The former factory, closed in 2000 and torn down in 2010, was not responsible for the PCBs, which flowed downstream from other sites. But PCB levels in the river in this part of Rensselaer County have been measured at up to 270 parts per million, well above the safety standard of 1 part per million.
