1st place: Clean Water AI by Peter Ma, Justin Shenk, Shin Ae Hong

Contaminated water affects more than 2 billion people according to the World Health Organization, and while we think water is safe to drink in the United States, events like the water crisis in Flint, Michigan, have proven we still face serious water safety issues. In addition, monitoring water contamination is extremely difficult and available water sensors are chemical-based, the most common one is a chemical test strip that can only be used one time.

Finding solutions for water contamination

To address this issue, Peter, Justin, and Shin, developed Clean Water AI — an IoT device that classifies and detects dangerous bacteria and harmful particles. With Clean Water AI, cities and towns can install these IoT devices across their water sources to monitor water quality as well as contamination continuously and in real-time.

Since building the project, the team has been invited to give demos at AIDC, CVPR and Intel DevJam, and plan on continuing development in the near future. Follow the progress at www. cleanwaterai.com
