HGS has over 20+ years experience drilling and service experience for domestic, municipal, and monitor wells.  HGS is a licensed water well drilling contractor in the State of New Mexico (License No. WD-1472).  HGS has experience drilling boreholes from 4" diameter to 24" diameter using various types of drilling methods. 

WELL REHABILITATION

HGS can perform a variety of maintenance and rehabilitation techniques which may be effective in restoring specific capacity, improving discharge rates, and protecting from further deterioration.  Some techniques are:

Re-development - sand pumping, swabbing, airlift pumping and swabbing, and surging with backwash.

Chemical re-development with acid or dispersing agents.

Mechanical cleaning by wire brushing or pressure jetting.

Structural repairs by setting liners or screen replacement.

WELL ABANDONMENT

HGS will abandon (plug) your wells or boreholes according to the New Mexico Office of the State Engineer regulations.   HGS's typical method of abandonment is to install tremie pipe near the bottom of the well or borehole and attach a well cap with discharge head to allow the water to disperse away from the well, which maintains a clean and safe work area.   Next, HGS will pump grout to approximately two to five feet below surface grade, cut the well or surface casing off and cover with native soil.

WELL PERFORATION

HGS has the capability of perforating wells from 4" to 16"diameters.  Perforation can be used to increase discharge production in wells, seals off specific zones, or abandon wells.
