Jack Driscoll-Natale was learning about measuring the health of local waterways for a class at Pacific Collegiate School his sophomore year when he realized there wasn’t enough publicly available data to complete his lab work. So he decided to build his own tool that can continuously monitor water quality. Now the 17-year-old senior is racking up awards and plaudits from scientists for his invention, which can upload a continuous stream of water quality data to a publicly accessible website for the fraction of the cost of professional equipment.
