Two University of Minnesota grads, Joe Mullenbach and Alex Johansson, are launching a water filtration startup company, according to the Star Tribune.

The technology, which reduces the amount of weed killer atrazine to a drinkable level in water, is a spin-off from research done by the University’s Lawrence Wackett and Michael Sadowsky. The EPA has long required that levels of atrazine are detected and treated in drinking water, according to the University.

This company is the 10th spinoff based on University technology and research findings in the last 18 months, according to the Star Tribune.
