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,

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.

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.
