NOVELTY - Preparing water with a stable negative oxidation reduction potential (ORP) involves preconditioning water received from a water source for electrolysis; performing electrolysis on the preconditioned water; outputting alkaline water and/or acidic water with a stable negative ORP.    USE - For preparing water with stable negative oxidation/reduction potential (claimed) for producing/tuning super oxygenated, structured water useful in aerobic processes such as in situ or ex situ bioremediation of contaminated surface and ground waters rehabilitation of atrophying lakes, biochemical oxygen demand measurement techniques, fresh water aquaculture etc. The water can also be used for increasing the oxygen content of blood and tissues, oxygenation of wounds, oxygenating organ transplant storage media, tumor oxygenation for radiation therapy and chemotherapy etc.; in cosmetics and toiletries; as food additives for e.g. beverages; in nutrition, medications and increasing overall cellular performance, exchanging liquids in the cell and removing edema; contact lens treating solutions; in pharmaceutical formulations (e.g. ointment or suspension for treating diseases of the eye, the skin and the lower intestinal tract; nasal aerosol and inhalation formulations in the form of eye drops, eye wash and nasal drops); useful for producing oxygen-enriched microstructured water preparations used for reducing and/or inhibiting the onset of fatigue in response to exercise in a human; for reducing muscle soreness/burning after extreme exercise; for treating infections and for inhibiting free radical damage in cells.    ADVANTAGE - The method adequately and sufficiently oxygenates and structures water, that when consumed provides a distinct and definite increase in hydration, oxygenation and healthy metabolic changes regarding organic life processes. The tuning super oxygenated, structured water maintains and/or restores desired physiological fluid oxygen level; maintains the oxygen saturation level and reduces and/or inhibits the increase in levels of blood lactate.    DESCRIPTION OF DRAWING(S) - The figure shows a block diagram of a system for making and tuning super-oxygenated and structured water.
