Thanks people. Thanks to all the input, we're now looking into bringing in a DMT to this project to produce the design data and using sonic to get the borings/soil samples/ and produce the holes for temporary piezomenters for groundwater samples. This rig will also have a cone penetrometer and...
Thanks DRC1 and we may have to go that way but many regulators don't like to accept the results of sampling when mud rotary is used. We've run into several EPA and State types that feel any subsequent environmental sample is suspect and refuse to accept the results of groundwater samples...
