DEM catches bad dirt at Portsmouth landfill cap
On Monday, RI DEM released information on two recent issues with the ongoing capping project at the former Portsmouth landfill. An e-mail from RI DEM principal environmental scientist Mark Dennen included attached letters to Arthur Palmer Enterprise and their site manager which detailed two episodes where soil with greater than 7 parts per million of arsenic were identified, the remedial actions required, and in one case, the threat of fines. Here's what Dennen said in his cover e-mail:
As you may know, the Department routinely takes split samples of soils received at the former Portsmouth Town Dump to verify sample analyses done by generators.
The enclosed Notice of Intent to Enforce was issued today regarding soils from Newport that were sampled as part of a routine inspection. As explained in the Notice of Intent, our sampling found that arsenic levels were above both levels reported and criteria set forth in the BUD (40 mg/kg). As these levels are not acceptable, soils will have to be delineated and removed. The Department also reserved the right to take additional enforcement action.
Also enclosed is a letter regarding soils accepted from East Providence sampled relative to a complaint. Although arsenic levels are within allowable levels for the BUD, they were significantly higher than reported. These soils will have to be appropriately managed.
