"River Pollution Studied ... Plants, fish and bugs collected from Rocky River by some 40 students at the first Cleveland State University seminar on pollution control will be examined this week as examples of what pollution does to life in a river. The two-week program, planned by Paul Olynyk of CSU, is for pollution control specialists from industry, government and universities. Here, Edward Hauser, Cleveland Metropolitan Parks naturalist (third from right), helps some students. Yesterday's field trip also included a visit to the North Olmsted Sewage Treatment Plant." -- photo verso.
