This issue contains articles that discuss a broad range of applications of chemistry to our environment. The three articles illustrated on the cover involve water chemistry. In the upper left, students from Evergreen College prepare to collect a sediment sample from Puget Sound (page 1594; photo by Frederick Tabbutt). In the upper right, students from the University of Washington conduct water quality analyses for community groups (page 1538; photo by the University of Washington). The water from the treatment plant shown at the bottom is analyzed for fluoride by students at the University of Texas at El Paso (page 1604; photo by Barbara Rum).
