1" PVC Prepack (1.7" OD)

ECT Manufacturing's Prepacked Screen monitoring wells are designed for setting small diameter groundwater monitoring wells. Prepacked screens consist of a standard, slotted PVC well screen pipe surrounded by a stainless-steel mesh. Sand is packed between the slotted PVC and the stainless-steel mesh. Since the sand is packed around the slotted PVC before the well screen is installed, using prepacks guarantees sand will be located directly around the well screen. This makes groundwater monitoring well installation quicker and more efficient than traditional methods. The 1-inch prepack uses a standard, 1 in. Schedule 40 slotted screen with a sand pack and 1.7 in. diameter stainless steel mesh screen on the outside. The 1.7 in. outside diameter can be used with 3.25 in. probe rods for an efficient combination of tooling for easy prepack installation. The 1-inch prepack is also avaiable with a 2.4-inch OD. The larger OD allows for a greater sand pack around the screen and is still compatible with the 3.25 in. probe rods. Prepacked Monitoring Well Benefits Quick and simple installation. Prepacked Screen designed with 20/40 grade environmental sand. No cuttings generated during installation. Meets all requirements of a RCRA well with exception of the smaller diameter. Permanent monitoring well installation with a Geoprobe® machine. Well seal and grouting meet EPA and ASTM D-5092 method requirements. Minimal disturbance of natural formation conditions. Can be developed, purged, and sampled using inexpensive tubing check valve system. Minimal development and purge water generated for sampling reducing time requirements and disposal costs. Uses standard above-ground or flush-mount well protectors.
