Roy Farms ASTs

The Site is the location of a farmyard.  An Environmental Site Assessment conducted discovered contamination at the Site.  Subsequent site characterization activities found gasoline, benzene, toluene, ethylbenzene, xylenes (BTEX) and diesel range organics in both soil and groundwater at concentrations above Model Toxics Control Act (MTCA) Method A Cleanup Levels.

In spring 2009, approximately 4,000 cubic yards of gasoline contaminated soil was excavated and stockpiled onsite for future disposal or treatment.  Roy Farms decided to land farm the soil onsite. Land farming activities began in early July 2009, with the spreading of the contaminated soil from the stockpile into a 1.5 foot thick lift of soil over plastic. The land farm area was near the middle of the subject parcel and covered an area of approximately 1.6 acres.  Sampling results suggested that, except adjacent to the shop, all of the unsaturated zone contaminated soil had been excavated.  
 
The remedial action also indicated the presence of contaminated groundwater and contamination along the surface of the water table.  Groundwater monitoring is being conducted at the Site.
