CITY OF SAN BERNARDINO - REQUEST FOR COUNCIL ACTION
STAFF REPORT
SUBJECT
Adopt the attached resolution authorizing the Mayor to execute an agreement between the City of San
Bernardino and EMCON, a contractor located in the City of San Bernardino, to perform the annual ground
water monitoring program for the former Waterman Landfill.
BACKGROUND
In 1950, the City of San Bernardino leased approximately 20 acres of land east of Waterman Avenue and south
of the Santa Ana River for use as a municipal solid waste (MSW) landfill for refuse collected by the City. The
City ceased use of the landfill site in approximately 1959, and returned the property to the owner in 1960. After
1960, the site was used by the property owner as a borrow pit and support functions for the former Tri-City
airport.
Various Federal laws establish requirements for the proper closure and long term monitoring of MSW landfills in
order to minirruze the potential for ground water contamination from leachate from the landfill. The City, the
current property owner, Glenborough and Associates, and the Santa Ana Regional Water Quality Control Board
(SARWQCB) have agreed to perform ground water monitoring at the site, and to prepare and implement a
closure plan to reduce the infiltration of water into the landfill site. The City, as the operator of the landfill, has
agreed to contract to perform the ground water monitoring of the site and to coordinate preparation and
submission of the reports required by SARWQCB.
The City previously has retained the services of EMCON to perform the quarterly ground water sampling
required by SARWQCB and to prepare and submit the required reports. EMCON has been performing this
work at the Waterman Landfill site continuously since 1992, previously under contract with Glenborough and
Associates, the current property owner, and since 1996 with the City. The City retained the services of
EMCON for performance of this work in order to maintain continuity and sampling integrity. They are most
familiar with the Landfill site, and have established an excellent relationship between the City and the
SARWQCB, which during FY97 -98 resulted in a renegotiation of reporting requirements from quarterly to semi-
annually, with a subsequent annual savings to the City of $5000.00.
EMCON has submitted a proposal dated September 21, 1998 to perform these services. This proposal is
attached and incorporated into the resolution by reference.
FINANCIAL IMPACT
The annual cost for performing the semi -annual ground water monitoring program is $34,592.00. Funds in the
amount of $35,000.00 were budgeted in the Refuse - Recycling /Environmental section under account 527 -415-
5502 Professional and Contractual Services for this program.
RECOMMENDATION
Adopt the attached resolution authorizing the Mayor to execute an agreement between the City and EMCON
Associates to perform the work as set forth in EMCON's proposal dated September 21, 1998.

Proposal 92098 - 060.081

San Bernardino, CA 92418
Re: Proposal for Fiscal 1998 -99 Quarterly Groundwater Monitoring, Inactive
Waterman Landfill, San Bernardino, California
Dear Mr. Merrill:
EMCON is pleased to present this scope of work and cost estimate to perform
quarterly groundwater monitoring for fiscal 1998 -99 at the inactive Waterman
Landfill. The purpose of the groundwater monitoring program is to evaluate
dowrlgradient and background groundwater quality in the vicinity of the site. The
groundwater monitoring will be conducted for the 3rd and 4th quarters of 1998 and
the ll st and 2nd quarters of 1999 under this proposal. Monitoring reports are
assumed to be submitted twice during this contract period, by October 15th 1998
and by April 15th 1999.
As requested in a letter dated December 18, 1991 by the California Regional Water
Quality Control Board -Santa Ana Region ( SARWQCB), a proposed monitoring
plan for the Waterman Landfill ( EMCON, October 1992) was submitted to the
SARWQCB as required under the California Code of Regulations, Title 23, Chapter
15, Article 5 (Article 5). On behalf of Rancon Realty Fund IV, EMCON submitted
(August 1993) a workplan for the groundwater monitoring plan to meet Article 5
detection monitoring program (DMP) requirements. The workplan was approved
by the SARWQCB in a letter issued on February 17, 1994. The groundwater
monitoring activities proposed below will be conducted by EMCON, consistent
with the DMP procedures and scope of work specified in the workplan. The work
includes the required constituents of concern analysis for 3rd quarter 1998 as
stipulated in the groundwater monitoring plan. The quarterly groundwater
monitoring and sampling will continue in the DMP mode unless the SARWQCB
requests additional assessment or changes to the program.

SCOPE OF WORK
Task 1 Groundwater Sampling
EMCON will collect one groundwater sample from each of the three monitoring
points during each quarterly event. The first sampling round under this contract
would be conducted during 3rd quarter 1998 and conclude with the sampling of the
2nd quarter 1999.
• Well WA -1, located hydraulically upgradient (south) of the landfill area.
• Well WA -2, located hydraulically downgradient (north) of the landfill area
• Well WA -3A, located hydraulically downgradient (northeast) of the landfill
area, possibly in a different hydrogeologic unit.
A depth to groundwater measurement will be taken quarterly by EMCON at each
well prior to sampling, for preparation of quarterly groundwater level hydrographs.
Purge water generated from quarterly groundwater sampling activities will be
containerized and left on site. Disposal of purge water is not included in this
proposal. However, we understand that the City will be authorizing EMCONs
earlier proposal for drum disposal. As part of that work EMCON will be requesting
that future purge water volumes be allowed to be discharged onsite in a fashion that
does not allow ponding to occur. The dates and volumes of purge water generated
from each well will be reported in subsequent quarterly reports.
Task 2 Laboratory Analysis
Groundwater and trip blank samples from the monitoring program will be analyzed
by a state certified laboratory (Columbia Analytical Services, Inc.) for the
monitoring parameters listed in Table 1 during the 4th, 1st, and 2nd quarters of
1998 -99 respectively. During the 3rd quarter 1998, samples will be analyzed for
the monitoring parameters listed in Table 1 excepting VOCs plus RCRA Appendix
II parameters as listed in Table 2. For the purpose of cost estimation, three

for analysis during each quarterly sampling event.

Task 3 Semi - Annual Reporting
Past practice has been to issue quarterly reports to the SARWQCB. EMCON
submitted a letter to the SARWQCB requesting a change to semi - annual reporting
which has been approved. Semi - annual reports will be submitted by October 15th
for 2nd and 3rd quarter 1998 sampling, and by April 15th for 4th quarter 1998 and
1 st quarter 1999 sampling.
The quarterly groundwater analytical results will be evaluated using the intrawell
and non - statistical methods. The concentration limits for each of these parameters
will be calculated as part of the statistical evaluation.

Following evaluation of the quarterly sampling results, a quarterly or semi - annual
groundwater monitoring report will be prepared that will include the following:
• A description of the sampling procedures
• A tabulation of well data, groundwater measurements, and analytical results
• A summary of activities or events which may affect the monitoring program
• A map showing monitoring wells
•
Time series plots showing the variation of concentrations of selected
constituents over time
• A summary of the quarterly statistical results and time series plots of selected
constituents (regardless of the reporting schedule)
• Recommendations, as appropriate
• Certified analytical reports and chain -of- custody documentation
BUDGET
The estimated cost to perform the proposed work is $34,592 as detailed in Table 3.
Sampling, laboratory analysis, and statistical analysis for 2nd quarter 1998 has
already taken place.
EMCON will invoice this proposed work on a lump sum basis, consistent with the
attached Table 3. Charges for work that is not a part of the proposed scope of work
are not included in the budget estimate.
The proposed cost and scope of work are based on information available to
EMC:ON at this time. If conditions change, unforeseen circumstances are
encountered, or work efforts are redirected, the cost estimate may require
modification.
