Hydrogeology drilling are intended to study groundwater behavior for environmental purposes such as landfill monitoring program or groundwater supply. We have experience to drill and installation of groundwater monitoring for hydrogeology study of for landfill monitoring programs (pollution detection). We also have experienced to drill and install the wells for water supply. The diameter varies from 4” – 8” pipe installation using the PVC or highly stainless steel material. The depth also varies from 20 – 350 m with the flow up to >55 m3/hour. We have experiences also to conduct hydrogeological drilling for mining drainage purposes. In this case inclined drilling were applied so that the drilled holes was perpendicular to the water bearing layer.
