Learn what water filtration system is best for you. rnrnAn ecologist with more than 30 years experience working in environmental science, Sweetwater founder James P. McMahon specializes in water quality and designing systems for the discerning health conscious consumer. Based on the premise that water filtration systems must vary according to where a person lives as well as the contaminants present in the water, Sweetwater is committed to creating solutions tailored to YOUR water. We start by identifying the contaminants in your water specifically (not all water sources are the same) and then I advise you which of my systems will remove that group of contaminants.
