The proposed project involves the abandonment of an existing groundwater monitoring well (MW-21) located on the north east portion of Cesar E. Chavez Park located in San Diego, California. MW-21 will be abandoned using a track-mounted hollow stem auger drill rig. Concrete from the surface well box will be removed using a jack hammer. The jack hammering will last for approximately five to ten minutes, and removal of the concrete from the surface well box will last approximately 1.5 hours. The well will be over-drilled with a hollow stem auger to a total depth of 21.5 feet, which is the total depth of the well boring.
