| TITLE: | Regional monitoring of pollutant movement in the sediments of the unsaturated zone above the coastal aquifer |
|---|---|
| PROBLEM: | Groundwater monitoring does not detect pollutants before they reach groundwater table. |
| OBJECTIVE: | Organization of a regional system for monitoring the movement of pollutants in the unsaturated zone above the coastal aquifer |
| APPROACH: | Use existing large diameter wells with insulated walls as monitoring wells, drilling of horizontal holes through the walls into the unsaturated sediments at different depths above the water table and placement of porous cup samplers therein. Sediment samples obtained during drilling will be analyzed for water content and for concentration of dissolved and adsorbed pollutants. Chemical and microbial analyses of samples taken from the porous cup samplers at chosen time intervals will enable to follow up the movement of pollutants towards the groundwater table and to estimate its anticipated effect on groundwater pollution as time goes on. |
| BEGINNING DATE: | 1.4.1996 |
| ENDING DATE: | 31.3.1997 |
| COMMENTS ON DATES: | Prospect of extension for two more years |
| CURRENT PROGRESS OR INTERIM RESULTS: | The survey of existing large diameter wells has been completed. The first experimental monitoring well was chosen and equipped. A report on the first analyses was published. |
