Using the AMS Heavy-Duty Retractable Groundwater Sampler and the AMS PowerProbe 9500-VTR, we collected samples from 4-8 feet at the Nielsen Environmental Field School demonstration. The Heavy-Duty Retractable Groundwater Sampler are ideal for difficult lithologies because they are pushed using dual tube technology and are constructed using a slotted 1 1/4" extension as the screen (ID 0.5" with 0.010"/0.020" slots).
We'd also like to thank Woodward Drilling for all of their assistance at the Nielsen Environmental Field School demonstrations.
