Loureiro Contractors, Inc. installed a hydraulic containment system utilizing a
                                                     horizontal well designed to confine dissolved contaminants to the shallow aquifer 
                                                zone above and aquitard that extends over a portion of the facility where contaminated
                                          groundwater had been identified. Water from the horizontal well was allowed to drain by
                                     gravity into a wet well from which it is pumped into a treatment building prior to discharge to a 
                                 sanitary sewer under a Connecticut Department of Environmental Protection General Permit. 
                           
                          The 800-foot horizontal groundwater recovery well was installed underneath the facility's floor, and
                      then connected to a 17-foot deep wet well. An approzimately 100-foot long trench connected the
                   horizontal well and wet well to the groundwater treatment system.
