Purging of this well would be. difficult and, because the well is currently in <br /> use, not recommended. 'I"he sarnple should be obtained as per regular protocol using <br /> the following parameters: *,electrical conductivity,and temperature. After sounding <br /> for water level and allowing to equilibrate before sampling, samplus should be <br /> bbtained at the level of the pump. <br /> 0 The samples should be analyzes for all c-onstituents of concern: TPH as gasoline, <br /> TPH as diesel, and BTEX.
