Deliverables include ground-penetrating radar field notes, soil sampling field notes, monitoring well installation and sampling documentation, MAGS field notes, property line survey and intrinsic delineation manifests, and site assessment and project management reports.

Hi Carly, Southside: I would like to request a 90-day extension. I have the drillers scheduled to install the additional monitoring wells on Nov 12 and sampling scheduled Nov 19. I am working on the o -site access agreements to get those out this week. Do you think it would be a good idea to collect another round of samples from the three existing wells at the same time the new wells are sampled? This would not require an WCD/TACO due to the number of wells originally proposed.
Bolton: I am hoping to have the report finished and sent for review this afternoon. I would like to request a 30-day extension for this project.
Thank you, Leif Layton, Ph.D., P.E.
