PERSIA, N.Y. — An inactive hazardous waste disposal site in Persia has been deemed to no longer be a threat to public health or the environment.
The Inactive Hazardous Waste Disposal Site Program, the State Superfund Program, has reclassified AVM-Gowanda as a Class 4 site because soil and groundwater contamination has been effectively addressed at the site.
Actions taken to cleanup the site include:
- Groundwater extraction and treatment
- Installation of a subsurface permeable reactive iron wall
- Installation of sub-slab depressurization systems in 18 nearby structures as well as the on-site building to prevent vapor intrusion into occupied buildings
- Treatment of groundwater using in-situ (in-place) chemical oxidation through a series of injection wells
- Routine groundwater monitoring to assess progress toward remedial goals
Annual certification of site management plan will ensure the continued practice of measures put in place to prevent community exposures to site-related contamination.
