<br />Notes:
<br />1 Proposed maximum depth based on current knowledge of subsurface conditions and depth to groundwater in area. Depths may be modified based on the actual depth to refusal. If boring advancement beyond above depths is necessary, the SJCDEH
<br />will be notified to discuss.
<br />2 Number of soil samples to be submitted for analytical testing.
<br />3 Analytical Methods:
<br />TPH-CC = Total Petroleum Hydrocarbons as Gasoline-Range Organics (TPH-GRO), Diesel-Range Organics (TPH-DRO), and Motor Oil-Range Organics (TPH-ORO) by EPA Method 8015.
<br />VOCs = Volatile Organic Compounds by EPA 8260B
<br />SVOCs = Semi-Volatile Organic Compounds by EPA 8270C
<br />CAM 17 Metals = California Administrative Manual 17 Metals by EPA 6010/7471 and 6020 for arsenic
<br />RCRA8 Metals = Resource Conservation and Recovery Act 8 Metals by EPA Method 6010
<br />TPH-CC = Total petroleum hydrocarbons carbon chain as gasoline-range organics, diesel-range organics, and oil-range organics by EPA 8015
