SandSlotTM 

Filter Pack / Screen Slot Design

SandSlotTM is a proprietary design tool developed by Hydrogeologic/Environmental Testing (H/ET). This advanced program evaluates the aquifer formation sand, filter media, and screen slot size using scientifically validated equations. SandSlotTM determines the optimal combination to reduce turbulent flow, enhance permeability, and minimize mineral precipitation and dissolution. The result? Smarter, more efficient filter media and screen slot size designs that deliver superior performance and longer life. Whether you're installing monitoring wells, high-capacity water wells, managed aquifer recharge wells, or aquifer storage wells. SandSlotTM provides data-driven confidence for every design.
