“The use of KB-1® Plus to reduce TCP in situ, particularly at low initial concentrations, is an exciting advancement to tackle this emerging groundwater issue”. Melissa Schmitt
Substantial decreases in TCP concentrations, the degradation product propene, and increased Dhg abundance (Gene-Trac® Dhg) were all observed within 6 months. In one monitoring-well, TCP concentrations decreased from 38,000 to 220 ppt, in another from 1,200 to 1.4 ppt; below the California proposed MCL, suggesting bioremediation has the potential to meet the State’s stringent TCP regulatory goals.
Melisa Schmitt (Geosyntec Consultants) who has been active in the research program for the TCP culture sees the value in bioaugmentation. The use of KB-1® Plus to reduce TCP in situ, particularly at low initial concentrations (<50,000 ppt), is an exciting advancement to tackle this emerging groundwater issue”.
With growing regulatory attention on TCP the ability to cost effectively remediate these sites will become increasingly important. The future of Dhg in helping deal with this emerging contaminant appears bright.
