Minneapolis, Minnesota 55455 (612)624-2855 June 2, 1988 Honorable Wendell Anderson Honorable Charles H. Casey Honorable M. Elizabeth Craig Honorable Jack P. Grahek Honorable Wally Hilke Honorable Elton A. Kuderer Honorable David M. Lebedoff Honorable Charles E. McGuiggan Honorable Wenda W. Moore Honorable David K. Roe Honorable Stanley D. Sahlstrom Honorable Mary T. Schertler Dear Ladies and Gentlemen: As we anticipated at the May meeting of the Board, the Minnesota Department of Health has announced to the residents of Rosemount its intention to raise the Recommended Allowable Limit (RAL) for chloroform in private wells from 5 parts per billion (ppb) to 57 ppb. The highest measured level of contamination in any of affected residents' wells in Rosemount is 1.7 ppb. This increase in the standards for allowable chloroform in private drinking water will result in the University no longer being held responsi- ble by the MPCA for the construction of an alternative drinking water supply. As described in the attached background statement, tinder our written agreement with the MPGA the University had been proceeding to install a rural water system for the affected residents. Design and construction was halted in March to secure required permits but has not been restarted because we learned that the RAL for chloro- form would be relaxed. The MPCA has already indicated that it would support a decision by the University to terminate the construction of the water systema The administration is bringing -this decision to the Board for its consideration. After careful consideration of the alternatives, the administration - is recommending to the Board of Regents that the University complete the water system. Total cost of the system is estimated at approxi- mately $850,000. Only a small fraction of the total required (approximately $30,000) has already been spent or specifically committed. -Nevertheless the administration recommends this sub- stantial, one-time expenditure of money to complete the system for the following reasons: I 0 • Board of Regents June 2, 1988 Page 2 (1) the residents of Rosemount have realized hardship due to the chloroform in the water, and an expectation has certainly been created that a system of some kind would be constructed to alleviate this problem; (2) questions will remain about the safety of the well water regardless of scientifically set standards; (3,) the University has an implicit moral obligation to respond as a community organization to correct this problem; and (4) the long term interests of the University are probably best served by construction of the system and viewing it as one of the costs of the land which encompasses the Rosemount Research Center and recoverable at the time of any transfer of the land. Thus we are recommending that the University expend the resources to complete this project ($850,8100 + $80,000 settlement fees for well drilling). In making this decision, the Board should consider that this expendi- ture will be a "trade-off" with other pressing University needs. For example, other fire and life safety items will be further delayed. Other urgent needs could be met with these funds. Nevertheless, after much deliberation the administration recommends the completion of the rural water system but only if certain conditions are met, as outlined in the proposed Regents' resolution on the attached pa9e. Sincerely, ichard B. Heydinger Vice President Attachments c: Richard J. Sauer Vice Presidents Fay Thompson Proposed Resolution BE IT RESOLVED that with respect to the Consent Agreement entered into in 1985, the Board of Regents directs the Administra- tion to seek from the Minnesota Pollution Control Agency a change in the Agreement that terminates all provisions relating to instal- lation of a water supply system in the Rosemount area and delegates to the President the authority to execute such an Agreement. BE IT FURTHER RESOLVED that the Board of Regents hereby authorizes the planning, design, and construction of a rural water system as described in the materials presented to the Board subject to the following contingencies: 1) The City of Rosemount enters into an agreement with the University whereby it cooperates with the Univer- sity during construction, takes over the system once constructed, and assumes all responsibilities for the system including, but not limited to, maintenance, repair, replacement, or expansion of the system. 2) Each of the homeowners included in the drinking water advisory executes an appropriate release approved by the University Attorneys Office, including a release of liability for providing a drinking water supply including, but not limited to, any claims related to property value. SUI.111ARY Chloroform Groundwater Contamination Project Rosemount Research Center In the early 1960's, a serious problem of surface water contamination was recognized nationwide. Since the common practice of sewering waste laboratory chemicals exacerbated the surface water problem, the University of Minnesota began a program of collecting chemical wastes from laboratories and taking them to a remote site at the Rosemount Research Center (RRC) to be burned in a pit. This practice continued until 1974, when a local commercial disposal facility become available for incineration of waste chemicals. In 1904, a number of private wells immediately northeast of the RRC were found to be contaminated with chloroform. Chloroform concentrations ranged from 0.1 to 15 ppb; the recommended guideline for chloroform in private wells was 5 ppb. The Minnesota Pollution Control Agency (MPGA) and the Minnesota Department of Health (MDH) jointly identified an affected area including 20 wells and approximately 100 residents. At the request of the State agencies, bottled water for drinking and cooking purposes was and still is provided by the University to the off ected residents. A Consent Agreement between the University and the Minnesota Pollution Control Agency was signed in 1905. It required a Remedial Investigation (already underway), a feasibility Study, and Remedial Action. The Remedial Investigation included the installation of approximot.ely 30 monitoring wells, and several hundred water samples were collected and analyzed. A Detailed Analysis Report was preparared early in 1906, recommending new, deeper wells as the most desirable Remedial Action to provide an alternate supply for the affected residents. A prototype deep well was installed at one residence in the summer of 1906; this well was satisfactory in every respect except for the iron content of the water. Although this some installation was offered to all other residents, none of them were willing to accept this solution. Chloroform Project Pole 2 In the summer of 1907, discussions were begun with the City of Rosemount and the affected residents concerning the installation of a rural water system rather than private wells. A public meeting held in Rosemount in September indicated that a rural water system was acceptable to a majority of the residents. Work then proceeded on design of the system. In February 1908 a test well for the water supply was begun. In mid-February work on the project was stopped until certain details of property. access and other legal items could be worked out. About a week later, the University received verbal notification from the MPCA that the recommended allowable limit (RAL) for chloroform in private wells was about to be changed by MDH. The level was going to be raised from 5 to 57 ppb, a change that would eliminate the need for an alternative water supply, according to MPCA judgment. The change was expected to be announced within a week or two. At that point, the University put e temporary hold on its own internal work and the consultant was notified of the impending change. The University was strictig ordered not to release the above information. Announcement of the new RAL did not actually occur until Hog 12, rather than in mid-March, leaving the University in the very uncomfortable position of having taken action on information it could not reveal. At a public meeting held May 16 it was very clear that most of the residents still feel that they need the rural water system despite the change in recommended limits. The MPCA requested that the University carry out a complete round of sampling of each affected residential well before the drinking water advisory is actually lifted by MDH. Sampling was accomplished on May 23 and 24, and results will be available in two to three weeks. C111010form Project f'at'e 3 Description of Rural Water System The rural water system is designed to provide domestic quantities of potable water to the approximately 28 families included in the drinking water advisory issued by the Minnesota Department of Health in 1984. It has been suggested that the system should also serve the Vocational Technical Institute and the Rosemount Research Center. It will have sufficient capacity to allow the City of Coates to connect to it if they wish to do so. The system will be supplied by a Jordon aquifer well, located at the old Rosemount City Hall, which is outside of the area of chloroform contamination. The service line will travel east on Highway 42 from the supply well to a point slightly west of Highway 55; it will then travel north to Highway 38, west on Highway 38 to Highway 52, and south an Highway 52 to the north edge of Coates. A second line will be placed under Highway 42 to connect the Vocational -Technical institute and the Rosemount Research Center. The total estimated cost of this system Is $847,147, as detailed on the attached pages. This estimate includes the likelihood that some of the installation would take place under winter construction conditions. It must be emphasized that this figure is an estimate only. it is as accurate as possible, given certain basic assumptions, but final design criteria have not yet been completely established COST ESTIMATE FOR IMIZAL 1YATElt SYSTEM AND RESIDENTIAL WELL SAMPLING Delta No. 10-86-054 1.
