The WellConstruction drillingMethod field documents how the borehole was advanced during well installation. Common values include hollow-stem auger, direct rotary, and air rotary — each suited to different soil and rock conditions. Regulatory agencies and hydrogeologists reference the drillingMethod when interpreting well construction quality and sample representativeness. This field is required in most well completion reports submitted to state environmental agencies as part of site investigation documentation.
