The following LSPA practice tip was introduced at the January 2024 Membership Meeting, which was held remotely on January 17, 2024 via Zoom.  

Practice Tip of the Month

Use care whenever eliminating a contaminant of concern (COC) in indoor air as part of a risk characterization.  For example, although ethanol is commonly detected at background concentrations in indoor air and may even be present in soil gas, be sure you have supporting soil and/or groundwater data showing it is not present in those media when eliminating it as a COC in indoor air as part of a risk characterization for a gasoline site.
