Watershed association offi cials, regional planners and con sulting engineers have flocked to University Park to see The Living Filter in action Visitors by the thousands have toured the 75-acre facility, thousands more have viewed a film docu mentary on the project and hundreds have sent written in quiries The Living Filter is an ex periment, now in its ninth year, designed to determine if im purities in waste water can be completely “filtered out’’ by the -ancaster Wenger Implement, Inc.

A Corps of Engineers study for Cleveland-Akron, De troit, and Boston-Providence has sent consulting engineers to Penn State to observe The Liv ing Filter Chicago’s “Prairie Plan” is the most ambitious.

The Penn State ex periment, now in its ninth year, proves that treated waste water can be barged 130 miles to rural Illi nois and spread over farm and strip-mined lands to create a 10,000 acre park and recreation facility.' Interest in the Penn State project is world-wide; in the past year alone, inquiries have been received from the Baham as, Barbados, Czechoslovakia, England, France, Germany, In dia, Israel, Italy, Malta, Poland, Singapore, South Africa, Thai land, Turkey, and West Pakis tan All 50 states, Puerto Rico, and all the provinces of Canada have been heard from What Penn State offers sew age-weary communities is the world’s most intensive research program on waste water puri fication But the Penn State system does more than purify waste water. Sprayed on crops and trees, treated sewage makes them flourish. In this way, the plants themselves clean some of the water; they drain off its impurities by using them to grow. The rest of the effluent percolates through the soil, is cleaned by microbes it contains, and goes on to replenish water tables below For eight years, winter and summer, a team of scientists from eight departments in four colleges at Penn State has been gathering data on farm and *aSTE WatE R ™,-" WATER NOURISH CF f%>^ EXCESS I&& SOIL - IS CLEANED BY SOIL sf; v-*' i 1 ' forest land.

Two years ago, project scien tists had an exciting idea. Since The Living Filter rejuvenates soil as it purifies water, maybe it could he used on the worst soil of all strip-mine spoil banks.

A few dwarflike trees, plant ed to meet state requirements, are all that some spoil banks contain. In the unspiayed planters ab solutely nothing has grown, not even weeds. But in the irrigated planters a thick jungle of grasses and legumes has sprung up, and eight-inch tree seedlings are now over five feet tall, and still growing. If a dense cover of grasses can be made to take hold on spoil banks, it would provide (Continued on Page 17) l idmZKtM-fyattS MR. -OAIRYMANt BUILD YOUR T-FOR’PROFIT RAM AROUND NEER FEEDS...
