Aq ul*fer-Sto rage Change and Land-Surface Elevation Change
Monitoring in the Tucson Activc Management Area
2017-2020
Introduction and Results
: Aquifer-storage change has been monitored by the U.S. Geological Survey (USGS)
within the'Tucson Active Management Area (AMA) since 1996. Tile USGS began a
cooperative study with Metropolitan Domestic Water Improvement Di strict and the town
of Oro Valley in 1996 to monitor aquifer-storage change in the Lower Catlada del Oro
sub-basin. In 1998,the USGS began a cooperative study with the Arizona Department of
'eater Resources (ADWR), Pijna County, and the City of Tucson to monitor land-surface
elevation change and aquifer-storage change in the Tucson AMA. In 2003,these two
n or *torhig studies were combined, and the town of Marana joined the study.
Results of the monitoring period from 2014 to 2016 indicate that basin-wide positive
aquifer storage change occurred for the first time in the Tucson Basin and continues to
occur in Avra Valiey(figures 1 and 2). Estimated aquifer storage increased by 350,000
ac•e-ft in the Tucson Basin and by 280,000 acre-ft in Avra Valley from 2014-2016.
Additio ally, results from the extensonleter network show that water levels continue to
recover in both basins and rates of compaction are beginning to decrease or cease ill some
areas. In other areas, latent compaction from previous maximum water-level declines
continues to occur(figures 3 and 4).
This proposal outlines a scope of work for continued and expanded monitoring of both
aquifer-storage change and land-surface elevation change in theTucson AMA. for the
period of July 1, 2017 through June 30, 2020.
Aquifer-Stoi•age Change
Aquifer-storage can be monitored by measuring changes in gravity. As water is added or
removed Froin the aquifer, there is a change its mass and a corresponding measurable
change in gravity. Gravity also is affected by changes in land-surface elevation, so
monitoring of land-surface elevation change is essential for accurate measurement of
aqui -er-storage change.
Water levels in wells commonly are monitored to estimate aquifer-storage changes.
However, use of water-level variations entails significant assumptions about the
hydraulic properties of the aquifer system. One difficulty is the heterogeneity of
hydrologic properties of the aquifer; the alluvial sedi nients of the aquifer vary in
l ithology and texture, both laterally and with depth. Thus, data from individual wells inay
not represent aquifer characteristics soin.e distance away from the well. A, second
difficulty is monitor-well design; in Tucson Basin, most water levels are measured in
deep wells that tap multiple aquifer layers, most of which are confined and have
accordingly low storage properties. Vater levels in these deep wells are a coin.posite of
t
eater levels fron-i several aquifer un its. when these composite water levels are used to
estimate storage changes, the hydrologic properties used in the calc;ulatioii typically do
not reflect the range of aquifer materials over which the well is screened. Because of
these complexities and requisite assumptions, use of water--level variations as the only
indicators of storage change can be uncertain, and cannot be reliably extrapolated beyond
the well location.
Monitoring of gravity and water levels in Tucson Basin leas shown that large changes in
groundwater storage, as much as several feet of water, have occurred that were,not
reflected in comparable water-level changes. The extent to which water levels are
influenced by storage changes are directly related to the proximity of the well; to the
recharge area, Closer proximity yields an earlier and more discernible water-level
response, watcrwlevel responses also depend on the geometry and lithology of the
sedimentary layers in the aquifer system that wells sample. This information often is
incomplete, or uncertain, All of this points to the need for a combination of storage-
change and water-level data, which together enable defensible estimates of aquifer
specific yield distribution.
Land-Surface Elevation Change
Permanent land subsidence can occur in alluvial basins when water is removed from
aquifer systems (Galloway and others, 1999). Aquifer systems in unconsolidated rocks
such as those in the Tucson. AMA are supported by the granular skeleton and the pore-
fluid pressure. when groundwater is withdrawn and the pore-fluid pressure is reduced,
the granular skeleton is compressed,causing some lowering of the land surface. Both the
aquifers (sand and gravel) and aquitards (clay and silt) ofaquifer syste�ns are deformed as
a result of changes to the poise-fluid pressure and slceletoii, but to different degrees. Most
permanent subsidence occurs due to the irreversible compression of aquitards during the
slow process of aquitard drainage(over a number of years).
Permanent subsidence, seasonal elastic deformation, and uplift have been observed i11
"Noson Basin and Avra valley. Rates of compaction in Tucson Basin. in relation to water-
level decline have been less than 0.5 foot per 100 feet of water-level decline. Comparison
with the Eloy and Phoenix areas (greater than i foot per loo feet of decline) suggests that
compaction to date in the'l"ucson region has been largely elastic and recoverable.
Compaction and land subsidence can be slowed or stopped, and in areas having
appropriate geologic conditions, reversed to some extent by eliminating groundwater
withdrawals or through artificial recharge.
The City of Tucson has increased delivery of recharged, recovered, and blended Central
Arizona Project(CAP)water, while reducing pumping from the Central well Field, This
appears to have reduced or stopped water-level declines an induced recovery in most
areas. However, subsidence due to previous levels of purnping and maximum water-level
declines will continue in some areas into the future. Continued monitoring of areas
having the greatest potential for subsidence will provide information that resource
managers can use in the development and implementatioxi of mitigation efforts.

Objectives
The objectives of this project are to monitor aquifer-storage change and land-suI•face
elevation change within the'1`ucson AMA.
Approach
Land-surface elevation change is monitored at a network of benchmarks (figure 1)
throughout the Tucson AMA by illeasuring changes in land surface elevation over time
(approximately annually) with Interferometric Synthetic Aperture Radar(InSAR)and
targeted GPS surveys. The Arizona Department of water Resources (ADWR.) has an
InSAR program in the Tucson AMA. InSAR is a technique that utilizes interferoilletric
processing to compare the amplitude and phase signals received during one pass of the
satellite-based SAR platform over the AMA with the amplitude and phase signals
received during a second pass of the platform over the sane area but at a different tirne.
The InSAR data are used by ADWR to produce a land-surface elevation change map
over the sane time period as the targeted GPS surveys conducted by the USGS in the
'f"ucson AMA. The ADWR provides the elevation-change naps to the LSCS as all in-
kind contribution to the project in exchange fog•absolute gravity data collection ill the
other state AMA's. The GIBS data are then used to compare with and constrain the JnSAR
deformation information. The annual combined InSAR/CC'S product provides a much
broader coverage of land--surface deformation information than could be feasibly
obtained with GPS alone.
Aquifer-storage change is monitored by measuring changes ill gravity over time at the
swine network of benchmarks (figure 1). Gravity is affected by mass and distance; a
change in mass or a change in elevation will cause a change in gravity. Groundwater
depletion is a mass change and land-surface elevation change is a distance change, By
removing the effect of change in distance, changes in gravity are used to deterinine
changes in aquifer-storage.
Temporal-gravity surveys are used in the"Fucson AMA to detect local changes in the
gravitational field of the Earth attributed to water mass change. The method is readily
applied to measurement of aquifer-storage change in the AMA because of the occurrence
of significant variations in pore-space storage that result from ground-water withdrawal,
periodic natural recharge events, and focused artificial recharge. Two instruments are
used at the network of benchrnarks: the relative gravity meter and the absolute gravity
meter, 'I'he relative meter is the primary instrument by which differences ill gravity are
monitored at stable monuments. Much as control benchmarks are used i11 00111ventional
land surveying, repeated relative gravity surveys for ground-water storage monitoring
should include reference stations where the absolute acceleration of gravity is monitored.
The USCS uses a Micro-g LaCoste A-1 o field-portable absolute gravity meter to
establish these reference stations as needed. This is particularly valuable in a hydrologic
3
context where a number of absolute stations may be located throughout a basin, thereby
serving to constrain and adjust the gravity differences frons relative gravity surveys.
Gravity surveys are conducted approximately annually at the entire network of
benchmarks in order to estimate aquifer-storage change(figure 2). CI'S surveys also are
conducted annually at the portion of the network that previous surveys have shown to be
the most active areas of land-surface elevation change. The network of benchmarks may
be modified and/or expanded in areas of poor coverage to improve resolution. These
areas include Avra valley, Sahuarita, and central Tucson. Gravity measurements will
increasingly be made using the A 10 portable absolute gravimeter; this will allow for
fewer relative gravity measurements, thus improving the efficiency of data collection.
Benefits
Aquifer-storage monitoring
Microgravity surveys are an efficient, noninvasive means of measuring changes in the
amount of groundwater in Southwestern alluvial basins. Monitoring changes in
groundwater storage in the Tucson AMA is a means to monitor the status of the basin
aqu ife•s and to track the progress toward the statutory goals of the 1980 Groundwater
Management Act. This will be of value as water-supply entities in eastern pinna County
address needs to manage and augment groundwater resources. 'I"he most significant
value would accrue as the city further implements aquifer storage and recovery efforts in
Avra valley and the Tucson Basin. As the storage and recovery projects reach
anticipated capacity, pumping from the Central Well Field and Salivarita areas will
continue to be reduced. 11hisdecreased demand will, if withdrawals do not increase,
enable water levels in the aquifer to recover•,
water level data entail assumptions about aquifer and well properties, thus, monitoring of
gravity changes as pumping decreases in the basin currently is the only way to measure
attendant changes in the amount of water in the aquifer and determine if and when
aquiferrecovery is occurring. ' 'his information conceivably will serve as part of basis
for decisions regarding distribution of groundwater withdrawals to help ill mitigating land
subsidence or aquifer storage losses in particular areas.
Aquifer-storage change is one of the three components of the groundwater budget. The
other two are inflow to and outflow from the aquifer system. Measurement of aquifer-
storage change and measures and estimates of outflow enable better estimation of
recharge and development of a more reliable groundwater budget for the basin. Measures
of aquifer-storage change increase the reliability and utility of groundwater flow and
management models. Use of storage-change data to improve model calibration enables
additional reduction in the uncertainty of model results. The improved understanding of
the movement, distribution, volume, and availability of ground water, to which storage
monitoring contributes, enables more effective water management in the"Meson AMA
and in other areas of the State.
4
Surveys in the Tucson AMA since 1998 have provided previously unavailable data
quantifying recharge and storage changes. For example, the results of aquifer storage
change monitoring in the Tueson Basin between 1998 and 2012 indicate that storage
change and recharge can vary considerably frog year to year. It is possible that just a
few years may account for the majority of recharge to southwestern aquifers for an entire
decade or more. These data are being used to improve the understanding of the aquifer
systems and to improve groundwater flow models that will be used in resource planning.
Carter-sui-face elevation change monitoring
Some types of infrastructure are more sensitive to changes in land slope than other types.
Sewer systems are largely gravity driven, and are designed and constructed at slopes of
about 2 feet per 1,000 feet. Small slope changes can cause operational problems under
some conditions. Accurate determination of the rates, amounts, and distribution of land
subsidence, together with delineation of higher-risk areas, will provide data upon which
mitigation and protection plans can be based.
Subsidence rates will increase when the stress threshold between elastic and inelastic
compaction is exceeded. Because it is not possible to reliably estimate when the
threshold might be exceeded in the Tueson AMA, and infrastructure damage becomes
more likely, subsidence monitoring also provides a means to identify the type of
compaction that is occurring.
Groundwater withdrawals frorxr the city's Central well Field has been substantially
decreased as CAS' recharge and recovery reaches full capacity. However, regional
subsidence in response to previous purnping is unlikely to end in the near future. It will
continue until the aquifer system reaches pressure equilibrium, observation of the tinning
and magnitude of aquifer responses will further improve the understanding of land
subsidence and of how the aquifer{systems function. Monitoring data also will contribute
to a better understanding of the responses of the aquifer systems to withdrawals, and will
provide additional insight in future plans for well-site selection, recharge efforts, and
water-i nanagernent prograins. Additionally, monitoring data will continue to augment
and serve as ground truth for satellite-based informationthat the ADWR is acquiring to
enable broad scale assessments of regional subsidence in the Tucson Basin.
Differential subsidence refers to a relatively large arnount of subsidence over a relatively
short distance, and can cause focused effects. For example, localized subsidence of as
little as one-half inch can necessitate rebuilding a highway overpass. Differential
subsidence has the potential to separate p ipe j o ints of sewer and water lines --thl"s earl
lead to system disruptions and roadway darnage. Also vulnerable are the concrete lining
sections of engineered channels that rely on the integrity of expansion joints to prevent
flood damage. Costs to address such infrastructure failures are high. Awareness of the
distribution and magnitude of differential subsidence can Delp to guide the design and
implementation of maintenance and monitoring schedules, selectlori of monitorilig
methods, and the design and construction of future infrastructure.

Releva Lice ani. Benefits
I"his study addresses the science of aquifer-storage change and land-surface elevation
change within the Tucson Active Management Area, specifically related to groundwater
withdrawal and natural and artificial recharge. The study contributes to the goals of the
USGSstrategic science di•ection "A Water Census of the United States," as identified
and described in the Strategic Science Plan of the USGS (IJ.S. Geological Survey, 2007).
Data Managenmit Platt
USGS Fundamental Science Practices require that data collected for publication in
databases or information products, regardless of the manner in which they are published
(such as USGS reports,Journal articles, and web pages), must be documented to describe
l)the methods or techniques used to collect, process,and analyze data, 2)the structure of
the oLttput, 3) a description of accuracy and precision,4)standards for inetadata, and 5)
the methods of quality assurance.
`fhe gravity data for the project will be collected with a Micro Lacoste A-10 absolute
gravirneter and relative gravimeters made by Lacoste and Romberg and ZLS Corporation.
The gravity data will be collected using techniques consistent with published
Ok
inethodologies for using microgravity to investigate and monitor aquifer-storage change
and land subsidence (Pool and Schmidt, 1997; Carruth and others,2007; 11ool and
Anderson, 2007; Carruth and others, 2017 (in prep.)). The data will be added to datasets
previously collected by Carruth and others (2007)and fool and Anderson (2007) for the
I`ucson AMA aquifer-storage change and land-surface elevation change monitoring
project(lett :Ila .��ate•.L�s �s. cvlr•a'eetsl9�a '1- 1��� . All data collected will be published
on a publicly available database to be kept in perpetuity. The USES ScienceBase
(sciencebase.gov) database is a likely publication outlet.A digital object identifier(Dol)
will be generated for the published database. Data collected from previous years will be
stored and served on the database, and newly collected data will be published oil the
database as they are reviewed, checked, and approved.
All gravity data for the project will be collected, processed, reviewed, approved, and
published following QA/QC protocols established by the USGS Southwest Gravity
Program (U'SGS, in prep.). All gravity data will be collected by trained USES
personnel---------absolute gravity data will be collected approximately every 61nonths and
relative gravity data will be collected approximately annually. Gravity data will be
processed by USGS personnel in the office within 3 months of data collection. An
experienced reviewer will review and check the data for accuracy, then the project chief
will release the data as a published ScienceBase data release. All metadata will be
documented in the ScienceBase data release as well as in Carruth and others, (2017 in
prep), once published, the data will be fully accessible to anyone inside or outside the
LJSGS.
