Inspection and maintenance of groundwater monitoring wells in Soc Trang
From 6th to 8th July 2016, the IGPVN project in cooperation with the Division for Water Resources Planning and Investigation for the South of Vietnam (DWRPIS) and the Soc Trang Department of Natural Resources and Environment (DONRE) conducted a camera inspection and well maintenance at two groundwater monitoring wells in Soc Trang province (ST7 and ST11).
The purpose was to ensure proper operation of the monitoring wells before handing them over to the Soc Trang DONRE for management and operation. The two wells are located in Thanh Phu commune, My Xuyen district and Vinh Tan Commune, Vinh Chau district, Soc Trang province. Before, during a regular check in May 2016, the IGPVN project and Soc Trang DONRE discovered an occurrence of mud in those two wells.
The borehole camera Geo VISION Jr micro M1 (USA) was used for quality control and to measure the depth of the monitoring wells.
