We are required by the state to use FID's (not PID's) as part of our soil screening process during soil sampling activities. We currently use the Foxboro Century OVA. Does anyone have a recommendation for other FID's they have had good success with?
Does anyone know some good reference sources for comparing Air Sparging and Biosparging? I have been asked to look for documentation or recommendations comparing the different ranges for airflow rates for each method. (i.e. air sparge is typically 4-12 scfm and biosparge is typically 0-4 scfm)...
Are there any tests or guidance documents to determine if a sand is a flowing sand?
I am being pressured to perform a soil excavation as part of a remediation project, but my geologist strongly believes the sands become flowing sands once we get below the groundwater table. I would like a way...
