Abstract |
The New Brighton/Arden Hills/St. Anthony site is located approximately two miles north of the Twin Cities of Minneapolis/St. Paul, Minnesota. The City of St. Anthony, located directly north of the Twin Cities, is one of several communities which obtain its municipal water supply from the Prairie due Chien-Jordan aquifer system. The City of St. Anthony obtains its water supply from well numbers 4 and 5 and an interconnection to the City of Roseville's water distribution system. In June 1981, the Minnesota Pollution Control Agency (MPCA) and the Minnesota Department of Health (MDH) detected VOC contamination in the Praire du Chien-Jordan aquifer system used for municipal drinking water in New Brighton. Subsequently, the City of St. Anthony has also detected VOC contamination in their three Praire du Chien-Jordan aquifer wells; well number 3, 4 and 5. Well 4 is the city's major source of water. Well 5 and the Roseville interconnection are used for summer, peak, or emergency situations. Well 3 was shut down in early 1984 due to VOC contamination. As the number of contaminated wells within the Praire due Chien-Jordan began increasing, EPA initiated several Initial Remedial Measures. |
