Increasingly, consumers are attracted to rainwater for the quality of the resource. While surface and ground waters suffer from contact with the contaminants that are plentiful in those water sources, rainwater has fewer contaminants to deal with, and those can be reduced or eliminated by discarding the first portion of each rain event by using a “first divert” system, and by using the components and materials approved by the National Sanitation Foundation for rainwater collection. As a testament to the quality of rainwater, ARCSA endorsed six rainwater entries in the prestigious Berkeley Springs [West Virginia] International Water Tasting competition held in February, 2011. Rainwater from Texas-based SparkleTap won First Prize in the Purified Water category, and Virginia-based RMS took fifth place.
