A method and product are disclosed for extracting only dihydrogen oxide from subsurface strata containing a currently unusable product, or "MUC" (Matrix Ubiquitous Crude) with no environmental impact. EDOM Extraction of Dihydrogen Oxide Module) will extract water from the currently unusable product, Matrix Ubiquitous Crude for national use, emergencies and homeland security as well as the American public's common good. Extraction of Dihydrogen Oxide Module consists of a single or multiple stage replaceable subterranean module placed within the inside casing of a well casing that facilitates a customized water purification system designed for treatment of each specific quality of Matrix Ubiquitous Crude. The intended ultimate end use of the produced water will determine each Extraction of Dihydrogen Oxide Module's internal composition of customized water treatment components as dictated by comprehensive laboratory analysis.
