Memo Ground Water Analysis Report
\~ ~
. CITY OF HOPKINS
MEMORANDUM
Date: January 28, 1991
To: Honorable Mayor & city Council
,
From: steven C. Mielke, City Manager
Subject: Ground water analysis report
Attached you will find the chemistry results for the first
baseline sampling of the Hopkins Sanitary Landfill. This
report was submitted to the City and subsequently to the
MPCA l~te last week.
The findings of this report indicated that a number of
volatile organic compounds were detected in the groundwater
at various locations in the landfill. These findings give
rise to the probability that the City and/or State will be-
. forced to take remedial measures for groundwater pollution.
The highest concentrations and those drawing attention were
found in monitoring well #104 (MW-104). The findings by
Braun indicate that there is severe amounts of chemicals
found in the groundwater in the southeast corner of the
landfill.
Based upon this first sampling, it appears that a high
concentration of petrochemical agents (solvents, cleaners,
etc.) were buried in the landfill and are now polluting the
groundwater. I
This report has been sent to the MPCA, Senator Ted Mondale,
Representative sally Olsen, and consultants for the
Westbrooke Patio Homes Association. Additionally, I met
with Eileen Harvala of the Sailor to discuss the findings of
this report. There are several points which need to be
stressed:
o The contamination found in this sampling is not
found in our present drinking water. In fact,
there is no reason to believe that this
contamination is affecting the surrounding area or
the drinking water of Hopkins, Minnetonka or Edina
.'., and testing of the Hopkins system occurs regularly
and checks for these problems. The closest
. Hopkins well is found at the intersection of
County Road 3 and 11th Avenue.
o The groundwater contamination is found at the
uppermost ground water' elevation and is not being
found in the aquifers from which drinking water is
obtained.
o The contamination found in the groundwater in no
way negates the necessity of the methane gas
project currently proposed by the city. The issue
of groundwater is a separate issue from the gas
migration issue which is an immediate concern to
the townhome residents.
o Staff has scheduled a discussion of this report
with the City Council on February 12th. This is a
regular work session evening and will offer an
opportunity to answer specific questions related
to this new problem.
It is the recommendation of our consul ting engineers and
attorneys that the groundwater contamination is a separate
issue from the gas migration issue. It will take a long
time (2 - 3 years) to address the necessary steps which will
. be taken with the groundwater contamination and. again,
, unlike the gas migration problem, there is no immediate
, health threat associated with this groundwater
contamination.
The findings in this report, although discouraging, cannot
be totally unexpected. We have found from our investigation
that industrial wastes were collected within this, landfill
from Hopkins industries, Hennepin County facilities, and
surrounding communities. The types of materials that this
report indicates were acceptable materials to be buried in
the landfill in the 60's, and therefore, this problem is not
unique to this landfill.
The Sailor is planning to do an article on this information
in its Wednesday January 30th paper. I would expect that
the report will generate a lot of question and concerns from
Westbrooke residents and I would expect media coverage on
this finding. .
Please feel free to call me at your leisure if you have
questions regarding this report.

, RE: CMJX-91-0010 CHEMISTRY RESULTS - FIRST
BASELINE SAMPLING
Hopkins Sanitary Landfill
Hopkins, Minnesota
Dear Mr. Gessele:
Field personnel from Braun Intertec Environmental, Inc. (Braun Intertec) collected groundwater
chemistry samples from 9 monitoring wells at the Hopkins Sanitary Landfill. This was,performed in
accordance with the Minnesota Pollution Control Agency's (MPCA) request to initiate baseline
. groundwater sampling as part of the Closure Order. The samples collected from the monitoring wells
were analyzed for the parameters listed in Tables 1 and 2 of the MPCA Solid Waste Management
Facility Rules, Part 7035.2815, Subpart 14, Item C. The chemistry reports containing results of the
analyses are attached.
In summary, volatile organic compounds were detected in all monitoring wells, except MW-101 and
MW-105D. The highest concentrations of VOCs were detected in MW-104. Samples from all
monitoring wells contained various dissolved metals and/or other inorganic constituents. Please note
that the sample marked as MW-107 is actually a duplicate sample from MW-I05.
,
The following parameters exceeded their respective intervention limits, as specified in the MPCA
rules, in one or more wells:
Parameter Intetvention Limit (ppb)
Vinyl Chloride 00037
DichloromethaOne 12
1,2- Dichloroethane 0.95
1,2-Dichloroethylenes 17
Methyl Ethyl Ketone 43
Toluene 500
1,1,2-Trichloroethane ,1.5
Benzene 3
Arsenic 12.5

According to the MPCA rules, the MPCA must be notified of the above exceedances immediately.
To accomplish this, once you have reviewed .this letter, we will send a copy to Ken Meyer at the
MPCA
The MPCArules. also require the following:
. the wells be resampled immediately;
. the significance of the exceedances be evaluated in regards to potential sources and
j the need for immediate remedial actions;
. an evaluation of the need for changes in the monitoring system; and
. a written report be submitted describing actions taken in response to the above
requirements and other relevant contingency actions.
Because the attached results represent the first round of a baseline monitoring program, the above
requirements are either being addressed currently (i.e., second round of analysis is underway) or will
be addressed in the summary report following the third round of baseline sampling.
. Asstated above, the second round of baseline samples are currently being analyzed by our laboratory.
The third round of baseline sampling will take place this week. We will transmit the results of the
analyses to you as we receive them from our chemistry laboratory. When aU three sets of samples
have been analyzed, we will prepare a summary report discussing the results of three sets of sampling.
It is in this summary report that the laboratory results are interpreted within the framework of the
MPCA rules and the permit.
If you have any questions or comments concerning this letter, please contact Paula Connell at (612)
683-8785 or Mark Larson at 683-8746.
