| TITLE: | Development of methods for a quick warning system against groundwater pollution in Israel |
|---|---|
| PROBLEM: | Groundwater is the major source of Israel’s freshwater. Aquifers in densely populated areas with intensive economic activity are susceptible to chemical pollution which may often be practically irreversible. The present methods of monitoring register groundwater pollution after it has already occurred. Hence the need for an early warning system against anticipated pollution. |
| OBJECTIVES: | Design of a national early warning system on anticipated pollution based on novel optic detectors. |
| APPROACH: | Investigation of chemical detection methods with optic fibers, development of the analytic method and the required equipment, construction of a prototype and evaluation of its performance in the field. |
| BEGINNING DATE: | 1.7.1994 |
| ENDING DATE: | 1.7.1997 |
| CURRENT PROGRESS: | The first year of study has shown that the proposed method is efficient in immediate detection of organic pollutants in water. However, one of the conclusions was the need for a more sensitive detector both in the range and in temporal resolution. The second year was devoted to the construction of a new detector and to the investigation of the effect of hydrosoles on the florescence of pollutants in the water. A way was found to reduce this effect. |
