EON stocks ASTM flush threaded schedule 40 Riser (casing) for small diameter and Direct Push monitoring wells. The standard size is 5 feet in length with male by female threads. Other lengths available.
EON stocks ASTM flush threaded schedule 40 slotted well screens in five-foot length. Standard slot opening is 0.010 inch. Other lengths and slot openings are available.
Filter socks are tubular fabric filters that can be pulled over slotted PVC screens to help filter silt and sediment from entering the well. These can be effective for temporary wells or for helping prevent turbidity in small wells. For long term or high turbidity applications, consider using PrePak Screens.
EON’s PrePak well screens can be installed in open boreholes, through direct push casing, or as liners in larger diameter wells. The clean silica sand is graded and available in standard, fine, and ultra-fine grain sizes so the installer can minimize turbidity and maximize flow. The filter pack is secured to the PVC screen base with an overlay of ...
PrePak jackets enable the installer to turn PVC slotted screen into PrePak screen on an as-needed basis. The jackets are cylindrical tubes of silica sand having a stainless steel mesh inside and outside, with layers of silica sand between the mesh. The jackets slide over PVC slotted screen and are clamped in place over the slots. Jackets reduce ...
Bentonite seals are used above the PrePak screen to ensure placement of a water tight seal without relying on pouring or pumping sealing materials down the small space between the casing and borehole. The sleeve seal consists of granular bentonite clay pre-packaged around a short, flush-threaded casing section. The section is installed above the ...
The Foam Bridge is a short cylinder of compressible, non-porous, inert foam mounted around a short length of flush threaded riser directly above the PrePak screen. The foam is compressed to fit in the drive casing during installation. When the drive casing is pulled back to expose the screen, the foam expands to seal against the bore hole to ...
Direct Push well installations and one-time water sampling often require a drive point on the end of the casing to facilitate driving into the soil. The soft foam seal enables the point to fit snuggly in the casing so it won’t fall out before driving is started. The special aluminum alloy is durable and reduces shipping cost. Optional Anchor ...
