Abstract
The practice of artificial recharge of groundwater began in Europe during the early nineteen century. It has been practiced for more than 200 years through the world. In the United States, it has been practiced for nearly a century. Since 1960’s, the improvements in artificial recharge technology in the United States, includes the use of reclaimed wastewater as the source of recharge and ASR (Aquifer Storage and Recovery).
The adverse effects from contaminants in reclaimed water for articicial recharge are of immediate health concern. Therefore WHO and US EPA utilize risk assessment as a tool of evaluating the potential health risks from artificial recharge, even in some states of the United States have developed the regulations and guidelines for artificial recharge with reclaimed water.
A few artificial recharge of groundwater projects were practiced in Taiwan and the source of recharge water are mainly from the surface water. Droughts and floods are occur frequently in Taiwan which cause unsteady flow rate of surface water. However reclaimed water can offer a steady source for artificial recharge of groundwater. Groundwater is one of the main sources of protable water in Taiwan. Since therer is an increasing concern of human health and environmental protection, well planning and corresponding research are necessary for the projects of artificial recharge with reclaimed water.
This research project suggests a risk assessment for artificial recharge with reclaimed water which can be included in the planning stage of artificial recharge of groundwater projects and quantifying the risks of human health. According ro the risk values, the techniques and manipulations can be justified, in order to reduce the risk of human health.
