ADVANCES IN THE USE OF LNAPL TRACER DYES FOR REMEDIATION CHARACTERISATION IN FRACTURED BASALT
Maxfield, K. | CRC Care International Cleanup Conference, 8-12 September, Adelaide, Australia, 17 slides, 2019

LNAPL tracer dyes were used on an 8.5 ha plume within a fractured basalt aquifer to characterize LNAPL connectivity and flow in the aquifer. The aim was to generate direct empirical evidence of pumping-induced LNAPL flow between wells, characterize fracture connectivity and LNAPL flow properties, and quantify the LNAPL capture zones of recovery wells to place additional wells to optimize plume mass removal. Three dyes were used concurrently at four LNAPL extraction wells in four sequential doses for three months. http://adelaide2019.cleanupconference.com/wp-content/uploads/2019/09/M36b.pdf See page 162 for longer abstract https://www.crccare.com/files/dmfile/CleanUp2019Proceedings_FINAL.pdf
