10/19/2016 | It is stated that “Following treatment, the soil will need to be allowed to sit for a minimum of 24 hours prior to confirmation soil sampling to ensure that chemical reactions were complete and equilibrium in soil is established. LTE, under the direction of SandRidge, will collect one 20-point composite confirmation soil sample representative of each approximately 100 cubic yard interval. Each composite sample shall be field screened using a PID and a Petroflag kit (or equivalent, to verify the reduction in VOCs prior to laboratory analysis.”Each composite confirmation sample shall be analyzed for BTEX, TPH-GRO, TPH-DRO. |
