What sampling is required after the soil-screening sampling?
After the indicator contaminants have been identified from the soil-screening sample, further sampling for the indicator contaminants is required in accordance with Early Action provisions. Alternativelyand possibly the simplest course to followall Early Action samples, including the soil-screening sample, may be collected at the same time. Then, with a request to the laboratory for quick turnaround time, the soil-screening sample must be analyzed for all parameters noted above (in response to the first question of this fact sheet). At this time, too, all Early Action samples should be analyzed for BETX and PNAs (since these parameters are always required for used oil UST systems). Please note that a sufficient amount of soil should be collected per sample location for later testing of other indicator contaminants, if any. Upon completion of Early Action activities, if compliance with applicable remediation objectives is not demonstrated, further sampling will be required pursuant to r
