CCOP-GSJ Groundwater Project Report GW-9 Report of the CCOP-GSJ-DGR Groundwater Project Phase III Meeting 13-15 February 2019, Chiang Mai, Thailand Technical Report of the CCOP-GSJ Groundwater Project Phase III COORDINATING COMMITTEE FOR GEOSCIENCE PROGRAMMES IN EAST AND SOUTHEAST ASIA (CCOP) in cooperation with GEOLOGICAL SURVEY OF JAPAN (GSJ), AIST Published by Geological Survey of Japan and CCOP Technical Secretariat Youhei Uchida (Chief Editor) I. PREFACE Groundwater is one of the limited natural resources on the earth. Mainly due to ignorance about its importance, humans have caused various groundwater issues by their activities especially in the late 20th century. Today, land subsidence, seawater intrusion, and groundwater pollution by toxic substances are serious problems everywhere in the world. The countries in the East and Southeast Asia also have faced many groundwater problems which need international cooperation to be solved. The CCOP-GSJ Groundwater Project was launched aiming to provide some solutions for groundwater management in the CCOP region. The Groundwater Project Phase III started in February 2015 aiming at the development of groundwater database in the CCOP region and three groups, the DB Groups I and II, and the Public Policy Group were formed to promote the project smoothly. The CCOP-GSJ-DGR Groundwater Project Phase III Meeting was held in Chiang Mai, Thailand on 13-15 February 2019. It was the final project meeting for the Phase III and attended by 27 participants from Cambodia, China, Indonesia, Japan, Republic of Korea, Lao PDR, Malaysia, Mongolia, Myanmar, Philippines, Thailand, Vietnam and the CCOP Technical Secretariat. In the meeting, participants confirmed the progress of the project from March 2018 to February 2019, and discussed the outcome of the Phase III including the publication of this technical report (GW-9). This “Technical Report on CCOP Groundwater Project Phase III” consists of the followings which the CCOP-GSJ-GA Groundwater Project Phase III Meeting in Bali, Indonesia, decided partially revised GW-7 and GW-8: 1. Report on the present status and future plan of hydrogeological maps in each country, 2. Explanation documents on the groundwater database of the country’s capital city or representative area registered on the GSi Groundwater Portal by the DB Groups I and II. 3. Public policy for the groundwater observation system created/proposed/developed by the Public Policy Group. Though the current problem varies from one country to another due to different hydrogeological and geographical settings, all the Member Countries should share the information to create a useful hydrogeological map in the CCOP region. I am very grateful to the authors for their invaluable contribution to the project and to their organization for giving the permission for the publication.
