In 2018, Inros Lackner Cambodia was subcontracted for Geotechnical Investigations for the Siem Reap City Network Development Project, which also comprised the installation of two groundwater monitoring wells to assess the groundwater regime. Groundwater level data loggers were installed in the wells for continuous level monitoring during a period of 12 months. Manual control measurements and data collections were carried out every three months and the data were submitted in quarterly reports. The well installation and water level measurements were conducted in compliance with ASTM standards.
