In addition, information obtained tfrom <br /> the coal exploration drilling program provided data to <br /> define : <br /> - the depth and horizontal extent of potential <br /> aquifer units , <br /> - the aquife- lithology and thickness and <br /> - whether the aquifers are confined (artesian) <br /> or uncon`ined (water table) . <br /> the company also obtained available informa- <br /> tion froi tie U .
