I want to install 2" PVC slotted monitoring wells to record groundwater fluctuations in wetlands here. I have done this in the past, but I cannot locate old info on sand particle size and/or bentonite used in installation. Does anyone have specs on these materials, and any ideas on vendors in the Pittsburgh area. Many thanks.
