HALTERN, Germany, Nov. 8, 2007 -- All the experts agree that in future there will be a massive rise in worldwide requirements for clean drinking water. EDI Exploration Drilling International GmbH in Haltern, Germany, is in an excellent position to meet this demand. "With our innovative drilling and well-building technology," says Christian Runge, the company's Managing Director CMO, "we will play an active part in the growth which is forecast for the water market. The significant advantages provided by our technology in terms of cost and quality offer the best preconditions for this, which is demonstrated by the fact that the Government of Namibia and Coca-Cola in Pakistan are already using our systems."

EDI's objective is to find water resources below ground under financially viable and environmentally sustainable conditions, and to ensure their long-term exploitation. For this purpose the company has developed a drilling system with which underground drinking water deposits can be accessed up to 40 per cent more cheaply than has so far been possible using conventional processes. The special feature of EDI's patented drilling process is that with a single bore hole as many samples as required can be taken at different levels, which also provides the decisive savings in time and expense.

The EDI Fluid Finder: successful in the search for drinking water
Ground water is the main source of drinking water. It is found in the earth at different levels, which are referred to as 'aquifers'. In order to tap these aquifers they first have to be discovered by drilling, and then made accessible on a permanent basis by sinking a well. However, often a number of aquifers containing water of different quality are located above one another.

This can be a problem if one aquifer contains clean drinking water while a different one has been contaminated by nitrates or pesticides. In nature such aquifers are cleanly separated from one another, but in the course of drilling their contents can become mixed up. The significant advantage of the system developed by EDI is that such a mixture is avoided, which enables an unambiguous and reliable analysis of each individual aquifer.

In addition EDI also has its own dedicated technology for preventing the mixing of aquifers in the subsequent well-building process.

EDI Exploration Drilling International GmbH is the German subsidiary of Exploration Drilling Inc. with its head office in Blaine, Washington State.
