Data from the 2015-2017 EPA All About Arsenic project is housed on Tuva, an online platform that makes it easy to visualize, explore, filter, interpret, and make sense of data in different ways, and to calculate basic summary statistics, and annotate graphs with arrows, movable reference lines, notes, and other highlighting tools. As students and teachers collect data as part of the SEPA All About Arsenic project, it will be deposited on the arsenic data portal on Tuva.
