When proposing to perform intrawell analyses at a facility, what is the best way to determine whether the proposed background from within each well has not been impacted?
Prior to performing intrawell analyses, a screening should be conducted at each well for volatile organic compounds (vocs). When vocs are present, an evaluation should be made to determine whether the landfill is the source, or whether something off-site is impacting the monitoring wells. Additionally, all proposed background data from within each well should be carefully screened for outliers, trends, and seasonal effects (i.e. cyclical patterns in data) which, if not addressed, may create limits that are not regulatory conservative.
