For further information, contact: (FOR IMMEDIATE RELEASE) BILL HAFLING, 373-2126 A University of Minnesota professor, active in the field of water pollution and sewage treatment since 1928, has been appointed as one of two engineering consultants to determine ways of combating pollution in the Potomac River in Washington, D.C. George J. Schroepfer, professor of sanitary engineering in the civil engi- neering department at the University, is an adviser to the government of the District of Columbia on the $60-million project. The other consultant is Pro- fessor P. H. McGauhey, head of the Division of Sanitary Engineering at the Univer- sity of Ca1if.ornia, Berkeley. Schroepfer said plans call for the District of Columbia Water Pollution Control Plant to remove up to 90 per cent of organic waste materials and solids from the sewage before returning the treated water to the Potomac. At present, the District of Columbia plant removes 75 per cent of such material -- as does the treatment plant for the Twin Cities area at Pig's Eye Lake. The original District of Columbia and Twin Cities plants both went into operation in 1938, "on practically the same day," according to Schroepfer. The improved Washington, D.C., plant is scheduled to be in operation by 1972. A study is now getting under way on the Twin Cities facilities also. Underlying the demand for improvement of these facilities are the factors of greatly increased popUlation in both areas as well as growing public awareness of the dangers of pollution. In the period from 1928 to 1945, Schroepfer rose from junior engineer to chief engineer on the design, construction and operation of the Minneapolis-St. Paul sewage collection and treatment project. He was also director of a coopera- tive research program from 1956 to 1968 for studying the past performance and (MORE) , -flOTOMAC -2- assimilative capacity of the Mississippi River. "There are a great many areas in the country with far worse pollution prob- lems than those faced on the Potomac, " Schroepfer said. "It's encouraging that the officials of the District of Columbia have recognized the problem and are doing something about it." The District of Columbia Water Pollution Control Plant is a metropolitan facility which handles sewage from the District and from extensive areas of Mary- land and Virginia which are tributary to the D.C. sewerage system in all, an . area of nearly 800 square miles. At present, significant amounts of sewage escape to the Potomac and tributary waters during heavy rains. Engineers in the department of sanitary engineering for the District of Columbia have pointed out that the poor appearance of the Potomac may be caused largely by muddy runoff and erosions from ploughed fields and construction areas. They also state that the effluent from the sewage plant is already cleaner in appearance than present river waters during storm runoffs. Because the present method of treatment at the D.C. plant does not attempt to remove nitrogen or phosphorus from the treated sewage water, this effluent causes the growth of algae in the Potomac. The District of Columbia's plans include the reduction of nitrogen and phosphorus compounds in the treated sewage as well as more efficient and economical collection and treatment methods in general. Schroepfer believes that it is best not to digest sewage solids as many treat- ment plants now do. He recommends instead that sewage solids be filtered and burned in the removal process. In this way much less "nutrient" material in the form of dissolved chemical compounds found in the sewage effluent is put back into a body of water -- such as the Potomac or the Mississippi. On Schroepfer's futuristic recommendation in 1938, the Twin Cities plant was designed much more economically -- and technically ahead of its time -- without digesters. Other cities such as Kansas City and St. Louis have recently adopted this technique. -UNS- UNIVERSITY OF MINNESOTA NEWS SERVICE-220 MORRILL HALL BRIAN CARNEY MINNEAPOLIS, MINNESOTA 55455 TO APPEAR SEPTEMBER 3, 1968 IN 'THE WHOLE' For further information, contact: (FOR IMMEDIATE RELEASE) JUDY VICK, 373-2126 Brian Carney will start off The Whole thing Monday, Sept. 16. The guitar-playing folk-rock and pop singer, who is also the son of actor- comedian Art Carney, will be the first Coffee House circuit rider to perform in The Whole, in Coffman Union at the University of Minnesota. He will play between 8:30 p.m. and 1 a.m. nightly through Saturday, Sept. 21. This is the first year that The Whole, a sub-basement coffee house with original pipe decor, has joined the circuit sponsored by New York's Bitter End Coffee House. The circuit, beginning its third year, includes about 120 colleges and universities throughout the country. It is considered an important outlet for aspiring talents. The Union Board of Governors, which conducts activities in The Whole, will host several other entertainers this year on the circuit. "For the first time good, inexpensive entertainment will be available to the students -- in an informal setting where the students can meet the entertainers and listen at close range," said Otte Boersma, a College of Liberal Arts junior from Holland who is governor of The Whole this year. Carney, 21, is from Bronxville, N.Y. He attended DePauw University before he turned his fulltime attention to a career as musician. He plays both the acoustic and electric guitars. Carney has appeared on television on the Merv Griffin Show, I've Got A Secret and the Dom DeLuise Show. He has played at the Bitter End and Gerdes Folk City in New York city; the Rathskeller in Mt. Vernon, N.Y., and the Charles Inn in Newport, MaIne. Admission to The Whole is 50 cents per person, which includes all the peanuts- in-the-shell one can eat -- ehells,goonthe floor. 'The Wh",le is apen to the public. -UNS- UNIVERSITY OF ~INNESOTA NEWS SERVICE-220 MORRILL HALL MUSICAL TROLLEY MINNEAPOLIS, MINNESOTA 55455 TO ARRIVE AT SEPTEMBER 3, 1968 MACPHAIL IN SEPT. For further information, contact: (FOR IMMEDIATE RELEASE) LYNN MARASCO, 373-2126 "Musical Trolley," an excursion into the arts for four-and five-year-old children, will begin the week of Sept. 16 at the University of Minnesota's MacPhail Center for the Performing Arts. The musical trolley is a new program designed to encourage early musical skill and talent and to provide a background for later, more formal instruction. The emphasis will be on developing skills in singing, rhythmic responses, listening, fundamentals of theory, orchestra instrument identification and musical creativity. Two puppets -- with the assistance of Betty Jo Mastry and Linda Rovang, MacPhail staff members -- will teach the musical trolley classes. The children will learn songs and singing games, musical terms and instruments of the four families of the orchestra, which they will have an opportunity to play. A puppet composer will introduce classical music. Music will be added to dramatizations of children's stories and poems during creative sessions in which the children will have a chance to sing alone, develop poise and create songs and actions. Participating children will attend a one-hour-and-45-minute class one day a week for 12 weeks, the day and time to be chosen by their parents. Classes will be held Monday through Friday, mornir.g dnd afternoon. Tuition is $30. Additional information is available from the MacPhail Center at 1128 LaSalle ave., Minneapolis, Minn. 55403; telephone 332-4424. The center is a part of the University's General Extension Division. -UNS- I . - ....
