Mission & Focus Areas
The foundation’s stated mission is to support and advance inclusive and sustainable communities by investing in the availability, quality, and enjoyment of water and increasing youth and young adults’ participation in science, technology, engineering, and mathematics (STEM) education.
Its water priorities are to reduce water stress and build ecological resilience (“Move”); improve water quality and reduce single-use plastic water bottles (“Improve”); and increase water safety and water-related wellbeing (“Enjoy”). Education support focuses on STEM career pathways, particularly engineering and manufacturing, for youth and young adults. Community giving encourages employee volunteerism and matches employee donations.
Grantees’ own missions illustrate the kinds of organizations supported. River Partners says it works to restore rivers by creating wildlife habitat, while Safe Water Network says it develops and scales solutions to help communities manage safe-water supplies. USA Swimming Foundation describes work to save lives, build champions, and serve communities through swimming; V3 Sports says it advances an individual recipient through wellness, fitness, and education. An individual recipient says it engages communities in caring for land and water.
