Integration of social and technical science in groundwater monitoring and management : groundwater pollution study on Lifuka, Ha'pai, Tonga Recharge study on Bonriki, South Tarawa, Kiribati / by L. Crennan

Abstract

On low lying coral islands, potable water is commonly sourced from shallow, fresh groundwater lenses. Although rainwater is also collected in tanks in the wet periods, dependence on the lense for all water needs becomes critical in dry periods. Protecting the groundwater from pollution is a major concern. In the management of reticulated supplies private land is sometimes converted to a public reserve to restrict access and use in an attempt to ensure that groundwater is protected from surface contaminants. Usually this is achieved by a lease agreement between landholders and the government utility and this arrangement can be politically, socially and economically contentious. However in the village context where private wells are still used by landholders, control of pollution sources is more practically complex, while still raising many sociocultural considerations.
