Sealed data loggers monitor groundwater level trends in Thailand

摘要

Farmers in rural Thailand rely on groundwater for irrigation and aquaculture; however gaining access to fresh groundwater is difficult due to the lack of technology and increasing saltwater contamination from shrimp farming and saltwater intrusion. King Phumiphon Adunyadet of Thailand recognised this problem, so he helped devise a plan to implement and fund a programme to determine pumping capacity and trends in groundwater levels through monitoring. He assigned the task of site determination and the development of a monitoring programme to the Thailand Department of Mineral Resources. The department chose miniTROLL dataloggers, developed by the US company In-Situ, to gather data from pumping tests.
