DISCUSSION
AGENDA ITEM: Well #1 Replacement
SUBMITTED BY: Kristina Handt, City Administrator
BACKGROUND:
On January 22, 2019 the City submitted a feasibility study regarding options to address PFAS
contamination at Well #1(located in the Old Village area) to the state (Minnesota Pollution Control
Agency, Department of Natural Resources, and Minnesota Department of Health). The feasibility study
examined six options: blend well 1 with other existing wells, interconnect with an adjacent water supply,
construct a new well and seal well 1, new storage facility to delay need for well, water treatment plant at
well 3 (southwest portion of city), and water treatment plant at well 1.
Staff met with state staff on February 20, 2019 and learned the state would support the city’s request for a
new well on a cost share basis given the increased capacity of the pump. Well 1 had a 500 gallon per
minute (gpm) capacity while well 5 would have a 1,250 gpm. Staff then had Bolton and Menk (who did
the feasibility study) obtain cost estimates on the difference. A copy of that analysis is attached in your
packet.
ISSUE BEFORE COUNCIL:
Is Council supportive of moving forward with this cost share on a new well? What other questions does
Council have related to this issue?
PROPOSAL DETAILS/ANALYSIS/OPTIONS:
Staff is bringing this item forward for discussion amongst council and to gather feedback as we move
forward.
The next steps would include having this item brought before the 3M Settlement Work groups. Staff would
then gather quotes from consultants to begin work on the new well. Work would proceed once a grant
agreement is in place with the MPCA. Well 5, as discussed last June, is proposed to be located in Tana
Ridge Park. Surveying, a test well and other detailed analysis by the city and state agencies would help
identify the specific location within the park.
FISCAL IMPACT:
The estimated city cost share per the cost difference analysis from Bolton and Menk would be about
$123,000. These funds would come from the water fund.
