Sustura, Inc. provides information to people of the quality and safety of their water. We do this through small scale internet of things enabled devices that measure the concentration of metals – lead, arsenic, cadmium, mercury, in the water in real time. These devices fit in the hand and onto customer taps, connect to our cloud servers where the data is processed, and provide an answer to the user on their cell phone in a second. For the first time ever, people can know if the water in their taps or bottles exceed any health thresholds and can obtain the best water possible for their families. The data our devices collect can be shared so users can communicate to each other which water is best, and can communicate to their water utilities where problems exist.
