Session 1: Sharing Groundwater Issues in Asian Countries
Key Points of the Presentations
Cambodia: issues of Arsenic contamination and mitigation measures
Mr. Mao Saray, Director, Department of Rural Water Supply, Ministry of Rural Development, Cambodia

Groundwater plays a crucial role by providing almost 53% of households drinking water in dry season;

Groundwater quantity is abundant in the country however quality issues such as Arsenic, Nitrate, Nitrite, Fluoride, Manganese, and E.coli contamination are critical;

Particularly, Arsenic contamination in groundwater is becoming a serious issue, about 0.2 million (in 1607 villages) are exposed to high risk aquifers along the Mekong river;

Government has given priority to address Arsenic problem and formulated the five-year strategic plan for mitigation of Arsenic;

Monitoring of groundwater quality, esp., for Arsenic, has been conducted in several provinces to index and map contamination level;

In addition, other approaches of mitigation have been taken such as awareness raising activities, providing alternative water sources, painting risky hand pumps, rainwater storage, and water filters;

Nepal: groundwater depletion in Kathmandu Valley (KV)
Mr. Hari Prasad Dhakal, Executive Director, Kathmandu Valley Water Supply Management Board, Nepal

Groundwater has been continuously depleting in KV for last 30 years mainly due to the increase of demand and lack of other alternative sources of water;

State water supply is not sufficient to fulfil the increasing water demand in KV so the gap is filled from groundwater extraction such as by individual users, KV drinking water supply limited, government institutions, hotels, industries, private water supply tankers;

In addition, contamination of aquifer through seepage of untreated wastewater is becoming a serious issue;

Information gap, mainly lack of comprehensive groundwater database, is a major challenge for preparation and implementation of groundwater management strategies;

Now government has given high priority to groundwater management, and a new groundwater management plan for KV has been drafted for approval;

Preparing groundwater database, identifying groundwater recharge areas, rainwater harvesting, registration of wells, and exploration of untested/unknown aquifers are the key elements of future strategies of groundwater management;

Mr. Hari Prasad Dhakal
PR China: groundwater problems and management challenges
Mr. Juanquing Yang, Vice Director, Centre for Groundwater Monitoring, Ministry of Water Resources, PR China

Groundwater in China is facing a lot of stress both in urban and rural areas such as from increasing water scarcity, aquifer depletion, contamination, land subsidence, salt water intrusion;

Groundwater levels are rapidly decreasing (by 0.5m/year in 13% of aquifers in northern China) and about a quarter of aquifers are already polluted;

China has come up with many laws and regulatory measures such as 'law on prevention and control of water pollution', 'regulation on water drawing permit management' , 'the most strict water resources management system';

Major challenge for government is difficulty in implementation of these laws and regulations, so implementation capacity should be strengthened;

Enhancing automatic monitoring of aquifers (in more than 10000 sites), including development of monitoring guidelines, are prioritised for effective management and regulation of groundwater extraction;

Enhancing technical and research studies on climate change impacts and groundwater modelling, raising awareness, information sharing, and public participation are other strategies for groundwater management;

Viet Nam: groundwater situation and emerging challenges
Ms. Tran Thi Hue, Head of Division for Water Resources Planning and Exploitation Management, Department of Water Resource and Management, Ministry of Natural Resource and Environment, Viet Nam

Groundwater is abundant (60 million m3/day of total reserve) but aquifers are distributed in different formations such as Quaternary and Neogene sediments, Limestone, Basalts, Hard rocks;

Groundwater constitutes 40% of water supply in urban areas and 80% domestic water supply in rural areas and it is a very important source of freshwater during dry season

About 600 million m3/year of groundwater is also used for irrigating high value crops such as coffee, litchi, peppers;

In 1998 groundwater has begun to be managed through the Water Law, however a plan for groundwater exploitation and protection has not been developed yet and awareness among people to protect water resource is still limited;

Aquifer depletion due to excessive exploitation is occurring in major cities and contamination of aquifers from organic compounds from industrial activities are becoming a serious concern;

In lower deltas in Viet Nam, influence of sea level rise due to climate change has been becoming a threat to groundwater resources;
