Resolution No. 2011-ROO65
ATTACHMENT A.2011
Described below is the scope of work and associated fees for Terracon to provide consulting services to the
City of Lubbock for the Hancock Land Application Site (HLAS) and Lubbock Land Application Site
(LLAS). This exhibit outlines specific tasks, budgets, and not to exceed amounts for Terracon to complete
the scope of work. Terracon's fee schedule that will be used for negotiating fees for Additional Services
not included in this scope of work is also attached.
Specific tasks to allow Terracon to assist the City to define project strategies and/or interface with the Texas
Commission on Environmental Quality (TCEQ) are included in this scope of work. In addition, Terracon
has included tasks to manage project data and prepare state mandated routine annual monitoring reports for
the HLAS and LLAS for submission to the TCEQ in May 2011. The 2011 Annual Report for the LLAS
will include an updated groundwater model for the LLAS that was originally revised for the 2010 Annual
Report. In addition, specific tasks are included to allow Terracon to collect and evaluate additional
information pertaining to water and soil quality, groundwater elevations, and new wells constructed in the
vicinity of the LLAS and HLAS. In addition, scope and costs are included for proposed Tasks 5.1, 5.2, and
5.4 but these tasks will only be completed once specifically authorized by the City of Lubbock.
Additional tasks such as the design and completion of an in situ pilot test to treat nitrate in groundwater may
be negotiated as Additional Services and may be added to this Agreement by amendment hereof.
Task 1 — Strategic Planning and Meetings
This task includes the review of updated project data as necessary, site visits, strategic planning with the
City of Lubbock, and interfacing with City of Lubbock Staff and TCEQ regulators. Terracon will meet with
City of Lubbock personnel to discuss strategic planning for the LLAS and HLAS including regulatory
compliance and closure issues. The strategic planning session(s) will address both short-term and long-term
planning. "The short-term planning discussions will include wastewater operations, farming operations, and
remediation activities at the LLAS. The long-term planning discussions will include the wastewater
development and water use planning and the beneficial use of the property. The long-range planning will
also be used to develop a monitoring, remediation, and closure strategy for the LLAS as well as to discuss
implications regarding the possible construction of Reservoir # 7 to the south of the LLAS. Two meetings
are proposed during the course of the year.
Terracon will assist the City of Lubbock with their discussions with the TCEQ as necessary. The LLAS is
currently operated, monitored, and remediated pursuant to a 1989 Agreed Order with the Texas Water
Commission (TWC, predecessor to TCEQ) but, as discussed below, the current intentions are to transition
operations, monitoring, and remediation to the permit. Terracon will assist the City of Lubbock as
necessary, and as requested, to evaluate technical issues pertaining to the permit.
Task 2 - HLAS
Terracon shall complete two main project tasks related to compliance with the City of Lubbock's TPDES
permit No. 10353-002 related to the HLAS. The two project tasks and associated work scope are
summarized below.
Page 3 of I I
Task 2.1 HLAS Data Hangcement
This task will involve database file management including database updates, preparation of supporting
graphs, and review of data provided by the City of Lubbock during the fiscal year. The City of Lubbock
will collect onsite groundwater samples, gauge monitor wells, and procure laboratory services. The city -
contracted laboratory will be NELAC accredited. Sampling data will not be reviewed and reported
pursuant to TRRP-13 (Review and Reporting of CQC Concentration Data). Thus, Terracon has not
included a usability review of the data or the preparation of a Data Usability Summary (DUS).
It is anticipated that the following data will be collected, compiled, and included in the databases during the
fiscal year;
• Annual groundwater level measurements from thirty-one offsite irrigation wells measured by the
High Plains Underground Water Conservation District;
• Quarterly nitrate data from southern onsite monitor wells (MW-IA, MW-2A, MW-34, MW-35, and
MW-36);
• Semi-annual nitrate data from 36 onsite wells;
• Annual static water level data from 36 onsite wells;
• Annual groundwater quality data from 36 onsite wells; and
• Annual groundwater quality field sampling data (i.e., pH, conductivity, oxidation/reduction
potential, dissolved oxygen, and temperature) from 36 onsite wells.
Terracon will integrate laboratory and field collected data into existing databases. Terracon will review the
data for trends and spatial distribution. Throughout the year, as data are compiled and reviewed, Terracon
will evaluate the data and communicate findings with the City of Lubbock staff and attorneys,
Task 2.2 HLAS Annual Report
This task involves preparation of the HLAS annual report. The HLAS annual report will summarize the
project history and monitoring activities, and will include tabular sampling and gauging results and maps of
nitrate iso-concentrations and potentiometric contours. Terr aeon will prepare a draft report that will be
submitted to the City of Lubbock and attorneys for review and comments. Terracon will work with the City
of Lubbock and attorneys to address any comments and will prepare a final report. The report will be
sealed by a licensed professional geoscientist or licensed professional engineer. The report is due to the
TCEQ by the end of May.
Task 3 - LLAS
Terracon shall initially complete three main project tasks related to compliance with the City of Lubbock's
TPDES Permit No. 10353-002 related to the LLAS. The three project tasks and associated work scope are
summarized below.
Page 4 of 11
Task 3.1 LLAS Data Management
This task will involve database file management including database updates, preparation of supporting
graphs, and review of data provided by the City of Lubbock during the fiscal year. The City of Lubbock
will collect onsite groundwater samples, gauge monitor wells, and procure laboratory services. The city -
contracted laboratory will be NELAC accredited. Sampling data will not be reviewed and reported pursuant
to TRRP-13. Thus, Terracon has not included a usability review of the data or the preparation of a DUS.
It is anticipated that the following data will be collected, compiled, and included in the databases during the
fiscal year:
• Monthly groundwater production data for approximately 43 recovery wells;
• Semi-annual nitrate data from approximately 150 site wells;
• Annual static water level data from approximately 150 site wells;
• Annual groundwater quality data from approximately 150 site wells;
• Annual groundwater quality field sampling data (i.e., pH, conductivity, oxidation/reduction
potential, dissolved oxygen, and temperature ) from approximately 150 site wells; and
• Quarterly North Fork data upstream of FM 400.
• Monthly lake nitrate data.
Terracon will integrate laboratory and field collected data into existing databases. Terracon will review the
data for trends and spatial distribution. Throughout the year, as data are compiled and reviewed, Terracon
will evaluate the data and communicate any findings with the City of Lubbock staff and attorneys.
Task 3.2 Groundwater Model Update for 2011 LLAS Annual Report
As required for the May 2011 LLAS Annual Report to the TCEQ, this task will involve preparing an annual
update to the existing MODFLOWIMT313 computer model prepared for the LLAS that was revised by
Terracon for the 2010 LLAS Annual Report. As directed by the TCEQ, the May 2011 LLAS annual
report will include a discussion of the revisions and update to the groundwater MODFLOW/MT3D model
to include a re -calibration of the model for 2011 to simulate flow conditions and water quality at the LLAS
over the next five year period. Terracon will procure the services of Dr. Ken Rainwater and his associates
to help extract useful data from the previous model, create a new model that interfaces with an existing
calibrated regional model of the Southern High Plains Ogallala aquifer, and calibrate the new local flow and
transport model based on current and historical LLAS and local data including new stratigraphic data
obtained from selected irrigation wells in areas to the east of the LLAS where very little stratigraphic or
water quality data exist. In addition to incorporating updated LLAS nitrate concentrations and groundwater
level data, the new model will reflect boundary conditions consistent with the Groundwater Availability
Model (GAM) and reflect the stratigraphic data developed by Terracon Consultants, Inc. during preparation
of the 2009 LLAS Annual Report and updated information from irrigation wells to the east of the LLAS_
For the purposes of this proposal, it is assumed that the majority of the aquifer properties used in the
existing model will form the basis of the initial modeling effort for the 2011 annual report and that the
report will include recommendations for improving/revising aquifer properties in future annual reports in
order to improve the model calibration. As such, the groundwater modeling task to support the preparation
and submission of the 2011 LLAS Annual Report will focus on those modeling tasks necessary to re -
calibrate and validate the model based on comparison of modeled data to actual data from the previous year.
Once the model has been validated to match approximate groundwater levels and nitrate concentrations, the
current nitrate concentration data will be input into the model to generate a prediction of future conditions
for a 5-year predictive period in accordance with the current Remediation Plan. The modeling description
and results will be presented in the 2011 LLAS Annual Report as described below.
Page 5 of I I
Task 3.3 LLASAnnual Report
This task will involve preparation of the LLAS annual report. The LLAS annual report will summarize the
project history and monitoring and remediation activities, and will include tabular sampling and gauging
results and maps of nitrate iso-concentrations and potentiometric contours. The May 2011 LLAS annual
report will also include a discussion of the revisions and update to the existing groundwater
MODFLOW/MT3D model to include a re -calibration of the model for 2011 to simulate flow conditions and
water quality at the LLAS over the next five year period based on the updated nitrate distribution in
groundwater and expected groundwater withdrawal rates, wastewater application rates, and typical rainfall.
Nitrate data from the offsite bottled water sampling program will also be evaluated. Terracon will prepare a
draft report that will be submitted to the City of Lubbock and attorneys for review and comments. Terracon
will work with the City of Lubbock and attorneys to address any comments and will prepare a final report.
The report will be sealed by a licensed professional geoscientist or licensed professional engineer. The
report is due to the TCEQ by the end of May each year,
Task 4 - Project Management / Communications
During the course of the project, there will be times when Terracon will need to provide overall project
management duties, communicate with the City of Lubbock staff, attorneys, the TCEQ, and with Agri -
Waste Technologies (AWT) regarding routine matters or to address questions that arise from operations and
management of the HLAS and LLAS. This would also include ongoing technical consultation to support
sampling activities for the onsite and offsite areas. Initial meetings with City of Lubbock staff and the
TCEQ in Austin are addressed in Tasks 1.2 and I.3. Additionally in Task 4, Terracon anticipates an
additional meeting with City of Lubbock.
Task 5 — Source Characterization Studies
The purpose of this task will be to conduct investigations of the soil and groundwater at various points within
and surrounding the vicinity of the LLAS to more accurately delineate the horizontal and vertical extent of
nitrate in groundwater, to evaluate the potential that deep-seated sources of leachable nitrate might exist in the
unsaturated zone beneath the LLAS, to investigate if denitrifying bacteria are present in selected locations to
aid in the natural attenuation of nitrate, and to use nitrogen isotope analysis to possibly identify other sources of
nitrate in groundwater (such as commercial fertilizer applications) that may not be related to LLAS irrigation
operations.
Task S.] Vertical N_yfiling of Nitrate Concentrations in Groundwater
Due to the significant amount of groundwater recovery/pumping from fully screened CL recovery wells at
the LLAS, a high degree of vertical mixing in the vicinity of the CL recovery wells is expected which would
likely obscure natural vertical gradients. However, in certain areas of the LLAS such as the area near
Yellow House Canyon and the eastern portion of the LLAS which are not located in the vicinity of CL
recovery wells, research conducted by the USGS suggests that there may be vertical stratification within the
aquifer. In order to understand vertical changes in compositions in certain areas of the site, a 3.7-inch
diameter straddle packer sampling system will be used to collect discrete groundwater samples from isolated
horizontal intervals for nitrate and total organic carbon analysis and field parameters (pH, dissolved oxygen,
ORP, and conductivity) along a vertical profile within selected monitoring wells. In general, the monitoring
wells are screened across a large interval from the top of the saturated zone to the base of the aquifer. The
screened saturated intervals typically exceed 50 feet and can range up to approximately 100 feet (MW-22).
In general, discrete groundwater samples will be collected at approximately ten foot intervals from the top of
the saturated zone to the base of each well.
Page 6 of 1 I
The proposed wells for vertical profiling include MO-05, MO-14, MO-22, MO-33, MO-84, and MO-96 and
generally span the existing plume from an upgradient to downgradient position. The proposed costs assume
Terracon labor and oversight but also assume that City of Lubbock sampling technicians familiar with the
site and protocols will provide sampling support.
"Task 5.1will only be completed once specifically authorized by the City of Lubbock.
Task 5.2 - Bacterial Testing for Denitrdfying Bacteria
Groundwater samples from selected wells will be analyzed for the presence and quantification of
denitrifying bacteria by Microbial Insights in Rockport, TN. The proposed costs assume Terracon labor and
oversight but also assume that City of Lubbock sampling technicians familiar with the site and protocols will
provide sampling support. The selected wells will include wells with low concentrations of dissolved
oxygen and/or where other nitrate concentration trends have exhibited decreasing concentrations which may
be indicative of denitrification. The possible presence of denitrifying bacteria, and the possible ability to
manipulate subsurface conditions in situ, could play an important role in the understanding and controlling
the fate and transport of nitrate in selected areas of the site. The proposed wells to be sampled include:
CL-2, CL-14, MO-04, MO-19, MO-58, MO-64, and MO-66.
Task 5.2 will only be completed once specifically authorized by the City of Lubbock.
Task 5.3 - Deen Seated Nitrogen InveNdeation
Irrigated cropland is a direct and indirect source of salts and nitrate in recharge to the High Plains aquifer. In
the Southern High Plains, playa lakes are thought be important topographic features for capturing rainfall and
irrigation run-off and focusing it as recharge to the underlying groundwater. Research by the USGS also notes
that large subsoil nitrate deposits from both natural and agricultural sources occurred in the High Plains,
Soil Borings and Nitrogen Analysis
Terracon understands that previous limited investigations of unsaturated soils beneath LLAS to a depth of
approximately 26 feet bgs encountered very dry soil conditions but did not identify significantly elevated nitrate
concentrations in soils below the root zone. However, as documented in the October 2009 DRAFT Work Plan
for a Revised Remediation Plan, USGS data at other sites in the High Plains Aquifer have generally identified
elevated nitrate in unsaturated soils beneath irrigated lands at depths ranging from 50 feet to 100 feet bgs.
Therefore, the scope of work presented herein includes the advancement of up to six soil borings at selected
locations at the LLAS to include irrigated areas, non -irrigated areas, and adjacent to what appear to be former
playa lakes or topographic depressions which may have potentially held ponded effluent in historical times.
The proposed costs assume Terracon labor and oversight but also assume that City of Lubbock sampling
technicians familiar with the site and protocols will provide sampling support and assistance. Soils will be
collected continuously using split spoons and logged by a geoscientist. Sample aliquots will be collected at
approximately two foot intervals (with focus on moist zones) and archived by the Iaboratory. Initially, samples
from approximately every four foot interval will be analyzed in the laboratory for soil nitrate (EPA Method
300.0) and soil moisture content to allow the results to be reported on a dry -weight basis. If elevated nitrate
concentrations are observed, additional archived samples from adjacent intervals will also be analyzed for
nitrate and soil moisture content. In addition, up to a total of 6 soil samples will be analyzed by sieve analysis
(ASTM D Method D422) for grain size distribution. At the proposed locations for the deep seated nitrogen
investigation, the depth to the water table is expected to range between 80 to 100 feet below grade. For the
Page 7 of 11
purpose of this cost estimate, it is assumed that the borings will extend to an average depth of 90 feet below
grade and that the spoils (soil cuttings) can be spread onsite on nearby roadways of pivot irrigator tracks.
Vacuum Lysimeter Investigation
Depending on the results of nitrogen content in unsaturated soils discussed above, the installation of up to two
vacuum lysimeters may be proposed in intervals beneath zones of elevated nitrate to determine if the
concentration of soluble nitrogen in the unsaturated zone is mobile and potentially changing with time, The
precise costs for installation of these lysimeters will depend on the depth of installation which is unknown at
this time. The estimated costs shown in the attached table are based on presumed installation depths of 25 feet
and 50 feet and assume that drilling conditions will allow the borings to stay open to facilitate installation of the
lysimeters. Once the actual proposed depths are known, revised estimated costs to install these lysimeters will
be provided to the City of Lubbock for approval. Costs are not included for follow-up sample collection or
analysis, which we assume can be conducted by the City of Lubbock.
Task 5.4 - Additional Monitoring Wells
Depending on the results of The City of Lubbock's efforts to sample private wells suitable for sampling in
some areas where elevated nitrate concentrations are suspected, additional groundwater monitoring wells are
recommended in certain areas in order to more accurately delineate the horizontal extent of nitrate in
groundwater. As discussed in previous Annual Groundwater Monitoring Reports for LLAS, the two primary
areas of concern where elevated nitrate concentrations have been observed and/or have exhibited increasing
trends are associated with monitoring well MO-96 and offsite domestic well B-29 in the eastern portion of the
site.
Monitoring well MO-96 is located to the south of the Jones Contract/210 Plot which is not owned or under the
control of the City of Lubbock. In general, while private irrigation and domestic wells are located in the
general vicinity of MO-96, there is a lack of groundwater monitoring wells to the west, northwest, and
southeast of the MO-96 to accurately delineate the horizontal extent and to establish concentration trends
associated with the hot -spot nitrate concentration. As such, depending on the results of possible supplemental
sampling of selected private irrigation wells to be completed by City of Lubbock personnel, three additional
monitoring wells are proposed to be installed to the northwest, west, and southeast of the area of elevated
nitrate concentration near MO-96.
Domestic well B-29 is located to the east of LLAS Plots 25, 26, and 27 in the far eastern portion of LLAS.
Previous investigations by Reed and Associates in 1989, and more recently in the 2009 by the City of Lubbock,
indicate that an area of elevated nitrate exists in groundwater to the east of LLAS Plots 25, 26, and 27 which is
not fully delineated. Domestic well B-29 was sampled in 2009 as part of the offsite bottled water sampling
program and exhibited 33.1 mg/L nitrate-N. As before, depending on the results of possible supplemental
sampling of selected private irrigation wells by City of Lubbock personnel, one additional monitoring well is
proposed to be installed to the east of B-29 in order to more accurately delineate the eastern extent of elevated
nitrate in groundwater in this area.
The wells will be installed by a licensed driller in the State of Texas and supervised by Terracon's field
professional who will provide visual soil classifications and prepare a soil boring log/well completion detail.
The proposed wells will be constructed of 4-inch diameter PVC casing and screen. It is assumed that the spoils
(soil cuttings) can be spread onsite in a relatively nearby area.
"Task 5.4 will only be completed once specifically authorized by the City of Lubbock.
Page 8 of 1 I
Task 6 — Evaluation of Revised Remedial Pumping Scenarios and Vertical Migration of Nitrate in the
Unsaturated Zone
The first objective of this task will be to evaluate a variety of alternative groundwater pumping scenarios
that could be considered at the LLAS in order to improve hydraulic control and reduce potential cleanup
times. The scope of this task will include application of the 2011 groundwater flow and transport model
and is designed to be much broader than the current TCEQ-mandated annual recalibration and update
required for the Annual Report which includes a five-year future projection of nitrate concentrations and
hydraulic heads. The first alternative to be evaluated would involve the potential optimization that might be
possible by utilizing recovery well locations within the constraints of the existing pipeline to the JBLS and
ground storage tank system. Groundwater capture zones over a 30-year future scenario will be developed.
This alternative would also evaluate a recovery configuration with potential lower overall yield that would
avoid the use of recovery wells from the general area where relatively elevated selenium concentrations
have been detected in order to reduce the selenium concentrations discharged to the JBLS. A third
alternative to be developed would include the consideration of alternative pumping centers and locations
that would include significantly higher overall groundwater recovery rates. As before, groundwater capture
zones over a 30-year future scenario will be developed. Particular attention will be made to understand the
hydraulic relationship between the groundwater and surface water within Yellow House Canyon.
The second objective of Task 6 will be to address ongoing concerns about the eventual movement of nitrate
stored in the unsaturated zone beneath the LLAS and the Ogallala water table. This work will include the
use of a public domain code, FEHM (Finite Element Heat and Mass transfer code), for modeling
unsaturated flow and the vertical transport of nitrate from the soil zone to the groundwater zone. The model
can be used to assess the residence time of nitrate in the unsaturated zone under various recharge scenarios.
This evaluation should provide useful information regarding the travel time of nitrate through the
unsaturated zone as well as the longevity of nitrate loading to the aquifer. This information will be
combined with investigation data and saturated transport modeling to guide the overall remediation
strategy.
Two project meetings are included in the scope of this task in order to meet with City of Lubbock personnel
to refine the planned approach and a follow-up meeting to discuss the results of the study effort and the
draft report. Terracon will prepare a draft report that will be submitted to the City of Lubbock and attorneys
for review and comments.
Estimated costs to complete Tasks 1 through 6 are presented in Table 1. Please note that these costs are
conceptual in nature and were prepared for planning purposes only, In some cases, written cost estimates were
received from selected vendors and contractors and these estimates are subject to change depending on the
actual timeframe for the work and the exact nature and scope of the actual work performed. In other
circumstances, no written estimates were received and some costs were estimated based on Terracon's
experience with this and similar projects. It is also assumed that sampling technicians from the City of
Lubbock will be available to assist with the sampling activities to facilitate the overall effort.
