Abstract: A control system for a fishing line for use during casting and during reeling in a fish. A line-gripper member can either pinch the line to terminate casting or can apply a drag to assist in landing a fish. The control system is intended to be mounted on a fishing rod and is particularly useful in combination with a spinning reel but also is useful with a drum or rotating, spool-type reel. An operating member is mounted adjacent a handle of a fishing rod to be actuated, usually, by a user's thumb for pulling a control line for actuating a pivoted line-gripper member and provide contact with a fishing line to provide a brake action or drag thereto.

Abstract: A groundwater protection system is provided for a surface impoundment or landfill wherein contaminated material is contained in a first compartment. A second compartment is located beneath the first compartment and contains a plurality of treatment materials for acting upon leakage from the first compartment. Treated leakage is collected by a drain system and is recovered therefrom for subsequent treatment and/or disposal.

Abstract: A chemical waste landfill comprising a plurality of compartments separated by and lined with a primary clay liner. A single integral synthetic water impervious liner is provided beneath the clay liners of all of the compartments and a primary underdrain system is provided for each compartment beneath the synthetic liner. A secondary clay liner is provided beneath the primary underdrain system and a secondary underdrain system is provided beneath the secondary clay liner. The invention also includes chemical waste landfills having in situ leachate treatment systems, increased security compartments having additional synthetic and clay liners and a leachate monitoring system comprising a plurality of standpipes interconnected by a liquid pervious means below the waste wherein the standpipes are protected by sleeves.
