A method of depleting a given analyte from a water source is provided. The method is applicable to water used in oil recovery, water used in natural gas recovery, the treatment of water wells, and for water used in hydraulic fluids for fracturing processes, such as water to be used in proppants or fracking fluids. The method involves depleting an analyte from a water source, said method comprising contacting a water source with a superparamagnetic or paramagnetic nanoparticle; complexing the analyte with the particle; and removing the analyte-particle complex by applying a magnetic field so as to provide a water source with depleted analyte content. The depleted water can then be pumped into one or more connecting injection well(s) in an oil field pushing the crude oil 10 towards one or more production well(s) thereby allowing for enhanced oil recovery from the production wells.
