DON'T MUCK IT UP Professor Jeff Tepper, geology, and Colin Glaze ’22 collect sediment samples from the bottom of Lake Waughop in Lakewood, Wash., as part of Glaze’s summer research project to identify the effects of alum treatment on the lake. The treatment is intended to reduce the lake’s hazardous algal blooms, improving the lake’s general condition to make it safer for humans and animals, but can have adverse effects on water and sediment chemistry.
