In order to assess the immediate and intermediate impacts of the December 26, 2004 tsunami on groundwater and associated water supply on the east coast of Sri Lanka, a monitoring program, focusing on domestic drinking water wells, was conducted in three study areas in the period March to July, 2005. The areas investigated were overlaying shallow, unconfined sandy aquifers, and the topography was flat. A total of 150 wells were monitored, covering both affected (inundated by tsunami water) and unaffected wells. Results indicate that wells were affected by salinity intrusion to various degree between the sites and within sites, up to 1.5 km inland. Thirty nine percent of all monitored wells had been flooded within a distance of 2 km from the coastline. Salinity levels after seven months after the tsunami were above a defined drinking water acceptability criterion (1000 µS/cm) in the majority of the affected, tsunami-flooded wells (91%). Excess salinity in wells is expected to persist for at least one more monsoon season.

The purpose of this case study is to describe the importance of groundwater for secure emergency water resource after the huge Hanshin-Awaji (Kobe) earthquake which occurred in 1995. Around 1,270,000 households were cut off from municipal water supply after the earthquake and medical activities in many hospitals were seriously affected by water scarcity. However, it was possible to pump groundwater from several wells immediately after the earthquake. Resistance of wells against the impact of earthquakes has been noted and registration system of citizen’s wells has been established in 1996 in Kobe. Within next two years 517 suitable emergency wells were registered and their location entered on maps. Based on the Kobe experience similar emergency water well systems have been established by many municipal and local governments in Japan to be used as a safe source of water in emergency. In some hospitals deep wells have been drilled, equipped with pumps and diesel driven generators and are prepared for immediate use in an emergency situation.
