RGA Environmental, a Terracon company, (RGA/Terracon) conducted soil testing of the stormwater basin at the Dinuba Service Center corporate yard. Prior to planned excavation, three soil samples were collected while the drainage pond was dry to characterize the soil. Boreholes were advanced to a depth of 5 feet below the bottom of the pond at each end of the pond using a power auger and/or slide hammer. A third borehole was advanced to 3 feet below pond surface in the center of the pond. We collected soil samples and filled the boreholes with materials excavated from the boreholes.
The soil samples were analyzed for the following constituents:
- CAM 17 Metals
- Total Petroleum Hydrocarbons (gasoline, diesel, and motor oil),
- Organochlorine pesticides by EPA Method 8081,
- Herbicides by EPA Method 8151,
- Volatile Organic Compounds by EPA Method 8260B,
- Semi-Volatile Organic Compounds by EPA Method 8270.
to determine if excavated soil requires additional evaluation and/or is classified as hazardous waste. RGA evaluated chemicals and metals concentrations against conservative regulatory agency screening levels for residential and commercial land use. We provided a report with laboratory analytical results and recommendations for excavated soil disposal.
