A new treatment could be next option for the PCB problem at the Altavista emergency overflow pond. Town officials are considering an experimental remediation plan to treat the contaminants. The process would fight the toxins with two techniques: the first includes planting switchgrass in the soil, the second phase would inject the plants with bacteria that can metabolize the PCBs. The DEQ has requested peer reviews and a risk mitigation report for the new method. The proposed experiment will come before council in November—Once approved, the process would span 12 to 18 months beginning this winter.
