Box 2007 o oak Park Heights, MN 55082 ® Phone (651) 439 -4439 0 Fax 439 -0574 Interoffice Memo To: Mayor and City Council From: Public Works Director, Jay Johnson, PE CC: City Administrator, City Engineer, Community Development Director Date: 02/1 7/00 Re: Authorization to Proceed with Well #3 In order to proceed with the construction of Well #3 the following authorizations are requested: 1. Approval of Resolution 00.02- Authorizing and directing the City Administrator and Director of Public Works to Begin Negotiations with the Department of Corrections to Acquire an Easement for the Municipal Well Construction 2. Authorization to conduct surveys of the three proposed well /water utility sites on at the Oak Park Heights Correctional Facility. 3. Authorization for City Attorney and Public Works Director process easement agreement for Well #3 to be located at the proposed central well site at Oak Park Heights Correctional Facility. 4. Approve draft plans and specs for well #3 drilling and authorization for the City Engineer to solicit bids. 5. Authorization for City Engineer to obtain request for quotes for test drilling at the central well site. 6. Authorization for City Engineer to prepare plans and specification for Well House #3. 7. Authorization for the sampling of Jordan aquifer wells which are near or within the well head protection area for the proposed well field. Total sampling and consulting cost not to exceed $5,000. Well #3 is required to provide adequate water supply during high use periods and have a back- up well. A three well system is required whenever the maximum daily demand requires two wells to pump simultaneously in order to meet demand and maintain a reserve for fire fighting. g Oak Park Heights 1996 Water Supply Study prepared by Bonestroo and Associates stated that Well #3 was needed and recommended that it be built in 1997. The Water Supply Study was updated in 1998 and again recommended that Well #3 be constructed. Based on a review of pumping records it appears that both of our wells were required to maintain the water towers at adequate fire fighting reserve levels for short periods of time during the summers of 1993, TREE CITY U.S.A. Memo to City Council: A :zation to Proceed with Well #3 02/17/00 1995, 1996, 1997 and 1998. If one of our wells had failed during these periods of time our fire fighting reserves would have been threatened. At the February 23, 1999 City Council meeting the Council authorized the City Engineer to prepare plans and specification for Well #3. Figure 1 shows the actual average daily water demand from 1991 through 1999 and three predictions for future demand. Based on the actual demand a three well system was required in Y q n 1992. The predicted average daily demand from the 1998 Water Supply Study is shown for 1996 through 2020. These predictions were based on past growth of 100 persons per year through 2010 and a slight increase after. Through 1 999 these predictions are in agreement with the actual demand. Since the Water Supply Study was completed several specific projects have been proposed which will increase the rate of population growth. The line labeled "Predicted Demand W/O Prison" is based on past growth and takes into account predicted growth due to VSSA, Central Business District, properties along Oakgreen Avenue, the Calthorpe Study Area, and Lower Oak Park Heights Redevelopment. It does not include the possible sale of water to the Stillwater Correctional Facility in Bayport. The line labeled "Predicted Demand With Prison" considers the predicted growth and includes a population of 1,000 people for the sale of water to the Stillwater Correctional Facility. Based on current growth predictions and if we supply water to the Stillwater Correctional Facility we may need to operate a four well system as early as 2006. The recommended location for Well #3 is the central site at the OPH Correctional Facility. The attached aerial photograph shows the three sites under consideration for wells. The northern site is predicted to be located at an underground valley in which the Prairie du Chen limestone has been eroded away by an ancient river. Without the limestone to form a roof above the Jordan sandstone, a Jordan well cannot be formed. The southern well site is located closest to the Baytown Plume. While it is not considered to be in danger of contamination (based on the current Wenk plume boundary), it is prudent to wait for additional data to be collected prior to this site being used. The central site is located near the underground valley effecting the northern site. To be sure that adequate limestone exist at this site a test boring is recommended prior to drilling the production well. The advantages of the OPH Correctional Facility site includes that it is within the current city limits, it is large enough to accommodate up to three wells without overlapping of their draw areas, and the draw area for the wells is primarily rural large lot residential versus urban, commercial or industrial. The northern well site could be developed as a glacial drift well or drilled below the Jordan aquifer. In either case it may not be as productive as the current 850 gallons per minute Jordan aquifer wells. With two Jordan wells producing and one in reserve a 400 gallon per minute drift well could satisfy the year 2020 maximum daily demand of 2022 gallons per minute. The southern site is shown as a location for a well, a future storage facility and possibly a future treatment facility. The future storage facility is not anticipated to be required until after 2004. The treatment facility hopefully will never be required. The Environmental Protection Agency has recently announced that it is modifying the groundwater treatment and disinfection rules. The attached map shows the draw area of our existing wells, the possible draw area of the new well field if all three wells were operated at the same time and the Baytown Plume. 2 TREE CITY U.S.A. Memo to City Council: A ization to Proceed with Well #3 02/17/00 The Baytown Plume is the area in which detectable quantities of trichloroethylene have been detected in the groundwater. Trichloroethylene has been used as a degreaser solvent, metal cleaner, and carburetor cleaner. Someone spilled or otherwise illegally disposed of it somewhere in the vicinity of the Lake Elmo Airport. The actual source has not been discovered. The plume has been investigated since 1988. Both the Prairie Du Chen limestone and the Jordan sandstone aquifers have been contaminated. The edge of the plume as defined by the October 1999 sampling results is approximately three tenths of a mile south of the southern well site. The Minnesota Department of Health has established a well advisory zone in which special precautions must be taken when drilling new wells. The edge of the well advisory zone is approximately 750 feet south of the southern well site. After reviewin g the available data on the plume, consulting with Northern Environmental, the Minnesota Department of Health and the Washington County Department of Health I believe that it is unlikely that detectable quantities of trichloroethylene would ever be drawn into the southern well or will migrate to any of the wells. The Health Risk Limit (HRL) established by the Minnesota Department of Health is 30 micrograms of trichloroethylene per liter of water. The HRL is 80 times the current detectable limit for testing for trichloroethylene in water. The primary weakness in the current sampling is the lack of sampling north of the confirmed location of the plume. To provide additional assurances that the northern edge of the p lume is well defined I recommend that the City initiate the sampling of selected Jordan aquifer wells which are located north of the Baytown Plume study area. A few samples located along Osgood Avenue between 47 Street and 50 Street and some along Northbook Boulevard within the draw area for our wells. The initial sampling would consist of approximately 10 wells with a laboratory cost of approximately $100 to $125 per sample and an additional $1000 for sampling, data analysis, and report writing. If trichloroethylene is detected in these samples an additional round of confirmation sampling would be necessary. The total cost for sampling if two rounds of sampling are necessary is estimate to be less than $5,000. A meeting has been held with the warden and his staff at OPH Correctional Facility to inform them of our interest in placing up to three wells across the front of their ro ert a future P p y9 storage facility, a possible future treatment facility if necessary, looping of water mains, future road right-of-ways being considered and park/trail improvements. They have provided us with verbal permission to perform surveys of the sites and their tentative approval for Well #3 on the central site with access from their patrol road and the understanding that the buildin g is designed to blend with their facility. The Department of Administration is the land agent for the State and will be the agency to execute the easement agreements. The attached draft easement agreement was prepared last year with the cooperation of the Department of Administration and our City Attorney. Other than adding the legal description of the ro ert p p y and some minor additions to make the document recordable this is the recommended easement agreement. 3 TREE CITY U.S.A.
