Degrove Supports NAVFAC SE Efforts for Gradient Study at Kings Bay Naval Base, GA.

Degrove Surveyors recently completed a monitoring well project at Kings Bay Naval Submarine Base in Kings Bay, Georgia.  Surveying services were in support of the Spray Field Gradient Study being completed by NAVFAC SE.  The study is being completed to determine the direction of groundwater flow from reused water spray fields.  Project tasks included completing a vertical control survey and also providing horizontal coordinate information on 23 monitoring wells located throughout the base – some being in very high security areas in which a full-time escort was required.  Despite having to cooperate with time-consuming security checks and daily vehicle scans, Degrove completed the project and delivered the information days early.  Field crews used digital levels and bar-code rods to achieve maximum accuracy and precision.  All vertical data was processed and adjusted using least-squares adjustment software.  Horizontal locations were determined with Trimble sub-meter GPS units.
