INTRODUCTION The San Antonio portion of the Balcones Fault Zone Edwards aquifer is a source of water for variou~ water use sectors including agricultural, industrial, and municipal. The aquifer has been designated a ''sole source" drinking water supply, by the Environmental Protection Agency, for approximately 1.3 million people in the San Antonio, Texas region. Currently, many of the cities in the aquifer region are totally dependent on groundwater for their municipal water supplies. More importantly, those cities' wells are

.located within a few miles· of the freshwater/saline zone (FSZ) interface of the aquifer, .... ~ommonly referred to as the .. '.'bad water line" (Schultz, 19~3). ..

The FSZ is the boundary line that separates freshwater in the north an,d northwest portion from saline water in the south arid southeast portion of the aquifer. It is defined as the salinity front containing total dissolved solids (TDS) concentrations of 1,000 milligrams per liter (mg/1) or more. Knowledge of flow hydraulics, including occurrence, sources, and mechanisms controlling flow patterns for this saline front, is limited due to lack of monitoring wells drilled into this portion of the aquifer. Hence, new drilling programs, as described below, are in progress.

Some wells located in the. saline portion beyond the FSZ have TDS concentrations of 6,000 mg/1, whereas TDS concentrations of freshwater wells usually range from 250 to 350 mg/1. Harden (1968) has documented apparent saline water intrusion during the drought of record that occurred in the 1950s. Further investigation has provided no conclusive evidence as to whether this intrusion occurred. In testimony before the Texas Water Commission, Harden (1992) reported that only 21 wells were sampled near the FSZ in 1956, including 15 wells in Bexar County. Eight of the 21 wells showed deterioration in water quality. Water samples from one well indicated that chloride concentrations increased from approximately 40 mg/1 to 300 mg/1, while water samples from another well indicated chloride concentration increased from approximately 400 mg/1 to over 4,000 mg/1. Harden (1992), in the late 1960s, also looked at a group of more than 130 wells and found water quality variations in approximately 60 wells. In 39 of the 60 wells, he folllld a correlation between water quality and artesian pressure. Eleven of the 60 wells showed variations that influenced use of the water for drinking water purposes. He pointed out that the Edwards Aquifer was far less "stressed" in the late 1960s than it was in 1956, when 50 feet of artesian pressure reduction occurred for five

3

months and led to cessation of spring flow at Coma! Springs, Landa Park, New Braunfels, Coma! County. Harden (1992) concludes that the way to decrease the possibility of bad water encroachment is to regulate withdrawals to maintain adequate spring flows.

, Freshwater/Saline Zone Transects The Edwards Underground Water District (EUWD), during 1985-1986, in cooperation with the San Antonio City Water Board (now San Antonio Water System, or SAWS), TWDB, and USGS began the construction of a series of seven observation/monitoring wells in a transect across the FSZ in the San Antonio area. The wells were constructed to characterize the hydrogeology in· the vicinity of the FSZ by collecting water level measurements and water quality data.

In 1989-91, EUWD continued to construct monitoring wells at two additional transect locations at New Braunfels, Comal County and San Marcos, Hays County. In 1993, a single well in south Medina County was constructed near the community of Yancey (Waugh, 1993).

This study significantly altered the perceived location of the FSZ as freshwater was discovered in the aquifer much farther down dip than previously known. EUWD, sometimes in cooperation with the USGS, has sponsored several key studies of the FSZ

'··including Poteet et al, (1992), Schultz (1992, 1994), and Perez (1986). More. studies ate identified in Edwards Aquifel' Bibliograplty, Tltrouglt 1997, BAA Report 98-01, available online at httP://www.e-aquifer.com. '

SAWS Saline Water Study SAWS, in cooperation with TWDB, USGS, The Edwards Aquifer Authority (BAA, formerly EUWD), and other local, regional, and state agencies, has initiated a ten-year Saline Water Study project to expand the network of wells that monitor the FSZ. Thirty­six new wells are to be drilled, while 22 existing wells will be reworked and equipped to monitor water levels and water quality on both sides of the boundary, resulting in a network of 58 wells.

The project is the result of a City of San Antonio Mayor's Citizens Committee on Water Policy that recommended in 1996 that a comprehensive study be conducted on the FSZ and the potential saline water intrusion into the freshwater portion of the aquifer. The first phase of the SAWS study for drilling monitoring wells near Kyle, Hays County was approved by the SAWS Board of Trustees and endorsed by the San Antonio City Council in October 1996. Since November 17, 1997, 18 wells have been drilled, tested, and completed.

The Kyle group, consisting of four wells, was established during 1997 and 1998. They represent the beginning of the network of 58 wells to be established along the .FSZ between Kyle and Uvalde, Uvalde County. John Waugh, SAWS, (personal communication) indicates that scientists have been analyzing geologic, hydrologic, and water quality data from the wells. Data review indicates that two of the four wells are

4

located over the saline zone. One of the fresh water zone wells has been completed along the fresh/saline water zone interface, and has fresh water above saline water in the well water column. At least two of the four wells have been equipped with continuous-read water level dataloggers since February 1999. During 1999, USGS, in cooperation with SAWS, installed telemetry systems at two of the SAWS Saline Water Study Kyle wells.

A second group of wells has been established in eastern Uvalde County. The four wells were drilled in cooperation with BAA and TWDB. Review of the data from these wells indicates that two of the wells are located over the saline portion of the aquifer. Igneous rocks were identified in both wells. The igneous rock differs slightly between the two wells atid is presently considered as two separate "sills" that intruded above the Edwards formation. During the fall of 1999 a continuous-read water level datalogger was installed in one of the fresh water wells. USGS, in cooperation with SAWS, installed telemetry system at the three remaining wells during 1999. Water quality information has been collected from all four wells and quarterly sampling is scheduled for calendar year 2000. Data gathered from these eastern Uvalde County monitor wells is useful in both the SAWS Saline Water Study and the BAA Knippa Gap Study.

Drilling for the third well group, located between San Antonio and New Braunfels, began during August 1999. The first well, located in Guadalupe County near Schertz was completed in Septemb~r, and was initially sampled_ for water quality as well ~ water level data. This well is located in the fresh water flow path leading from San Ant~nio to Comal Springs, and will provide valuable information concerning phanges in aquifer conditions during future short- and long-term drought periods. The second well, located near Cibolo was completed in October 1999. This well is located in the saline portion of the aquifer. Three other wells in this transect have since been completed. The position of the well group will also be of value to the surrounding communities, such as Schertz, which use Edwards water from an area close to the position of the "bad water line".

Drilling on a fourth well group has been completed south of San Marcos. These wells (three) are located on properties owned by SWTSU or the United States Fish and Wildlife Service's San Marcos National Fish Hatchery and Technology Center. Drilling is currently underway on a group of wells in Bexar County.

· The Saline Water Study is establishing a network for long-term monitoring of changes in Edwards Aquifer water level and water quality over the next 50 years. SAWS and associated researchers from the region expect the network of wells to provide conclusive data concerning the possibility of movement of the bad water line, as well as a "sentinel" system to warn of any sudden changes preceding possible movement.

Background of the Present EARDC Monitoring Network, 1996-2000 During the drought of 1996, concern was expressed again over possible movemenfofthe FSZ because of reduction in artesian pressure. After several seminars presented by regional scientists concerning FSZ issues in the aquifer region, a proposal was submitted to the TWDB by EARDC, in cooperation with USGS and the Guadalupe-Blanco River

5

Authority (GBRA). The GBRA's role in the project was to analyze water quality for "event-driven" samples using its laboratory facilities at Seguin, Guadalupe County.

The project was designed to strengthen and enhance the existing monitoring program undertaken by the BAA and to provide a bridge to the developing of 58 SAWS sites. The twp-year project, including data collection at six sites along_ the FSZ, was approved by the TWDB near the peak of the drough~ of 1996. The project consisted of daily monitoring of temperature ec) and specific conductance (f.ts/cm or J.Lmhos/cm) at two spring sites, three well sites, and a cave lake, using telephone telemetry for data collection. Dissolved oxygen (DO) measurements were also collected from the cave lake. In July 1998; the project was· extended for another two years to conclude with a report deliverable by March 2001. The project also provided support for the Mt. Baldy well, located in the Woodcreek community, Hays County. This well monitored daily water level in the middle Trinity aquifer and precipitation. A graph and tables of collected. data from 1997-2000 is included in this report.

METHODOLOGY Monitoring instrumentation was placed at critical points along the FSZ from San Marcos to just southwest of San Antonio (Fig. 1). Locations ofthe six sites, east to west, were:

+ 1. Deep Spring, San Marcos Springs, San Marcos, Hays County. Deep Spring is located approximat~ly 6. 7 meters below the surf<.1;ce of the lake; ..

+ 2. SWTSU Flowing Well, San Marcos, Hays County. The well is located on the campus just west ofthe Freeman Aquatic Biology Building; ,

+ 3. Ezell's Cave Lake, San Marcos, Hays County. The cave lake, representing the water table of the aquifer, is located approximately 40 meters below the land surface, approximately 0.6 kilometers from Spring Lake;

+ 4. Comal Springs Run #3, Comal Springs, Landa Park, New Braunfels, Comal County. The site is also known as the "Gazebo Spring Run";

+ 5. Gibbs Sprawl Well, Converse, Bexar County; + 6. Atascosa Rural Water Supply Well #1, Atascosa, Bexar County.

The purpose of monitoring temperature and specific conductance was to provide a consistent set of measurements collected by a telemetry system that reports daily. A single, daily measurement for each parameter from each site was placed on the EARDC home page, http://www.eardc.swt.edu/. ·

Instrumentation Photographs of the instrumentation setup at two sites are provided (Figs. 2-3). The instrumentation selected by EARDC includes these components (Fig. 4):

+ A 12V -datalogger recording system, consisting of a Campbell Scientific, Inc. (CSI) model CR10 datalogger and a 12V-power supply. The power supply was supported by a 1 0-watt solar panel. The recording system was located in a weather resistant container provided by CSI;

+ A CSI 12V-modem and cellular telephone transmitter system consisting of a Motorola cellular telephone, and a Yagi directional antenna. A 2-inch metal conduit, approximately 10 feet in height, supported the weather resistant container as well as the antenna and solar panel;

+ A water quality sensor system including probes f9r temperature and specific conductance.

' csr provided the water quality probes that are enclosed in a sealed cabling system that links directly to the CRJO datalogger. The Ezell's Cave instrumentation package included· a Hydrolab® HzO multi-probe unit. This allowed for measuring DO as well as temperature and specific conductance. The telemetry system used a directly wired telephone. The National Park Service (Tucson, Arizona) made the Ezell's Cave system available to the EARDC FSZ monitoring program.

Additional instrumentation and instrumentation software needed to make the real-time recording system functional includes:

"·· \.,

+ an office personal computer (PC) with internal modem and uninterrupted power supply;

+ CSI software with a CRlO program unique to each site and Windows® 95 compatible PC 208 software for communication between each site and the office PC;

+ A PC laptop for use in field calibration of sensors at each site; recorder sensors were periodically checked with an independent method and after about 5 years of operation were essentially reading within O.l-0.2°C for water temperature and .within 3 J.tmhos/cm for specific conductance;

+ A Yell ow Springs Instruments, Inc. (YSI) 600R multiprobe meter for independent calibration of field sensors.

In operation, the instrumentation at each site records time and parameter data, maximally, at hourly intervals and stores the data on the CRl 0 datalogger. The antenna at each site is oriented toward a nearby cellular telephone tower operated by GTE. Once each day between 6:00 and 7:00p.m., central daylight time, each field site modem is initiated by its datalogger. This is done to conserve power and to minimize phone costs. The office PC has been programmed to call each site in tum during a "window" of approximately 20 minutes. When a connection is made with the site telephone system, the data is downloaded to the calling office PC over the GTE cellular network and filed as PC 208 data files. Occasionally, no cellular telephone connection is established between a field site and the calling PC (a minimum of five tries are made). In this case, the data stored .on the CRt 0 dataloggers are downloaded during the next calling cycle. These data files are easily converted to most spreadsheet software.

11

Special CRl 0 programming was necessary at the Converse and Atascosa well sites. These wells, if pumped, are pumped only a few hours per day and generally are not pumped at all on weekends. Therefore, a float-switch was provided in the flow cells containing the sensors at these sites. When the well is being pumped, the float-switch activates the CRlO datalogger and information is collected.

During periodic visits to the field sites, corrections are made to sensor values and the data files are adjusted as described below ·

Data Management Periodically, an EARDC staff member imports the CSI data files into a database using Filemaker Pro 4.0 software (Figure 5). Within this database program, a conversion script is run in order to flag any irregular data and to prepare the data for uploading to the EARDC webserver. After completion of the conversion process, the database file is exoorted as comma delimited text and is transferred to the EARDC webserver.

Finally the data files from each field site are loaded into a database management program (DBM) on the EARDC web page where queries from end-users can be answered. The database management program is an elaborate system written by Nisai Wanakule and includes continuous "bad-water line" database access.

Data and Information on EARDC Web·.Site ·. The end-user is now able to access data at all field sites on-line. The browser is directed to the URL of the EARDC "Bad-Water Line Mpnitoring Homepage (http://www.eardc.swt.edu/) and the end-user is able to choose data files. By clicking on the appropriate link, a common gateway interface, or CGI program, is activated which retrieves the requested data from the appropriate DBM file for a given field site and then displays it. The end-user is able to view the data in a tabular format.

GBRA Laboratory Analyses As mentioned, the GBRA laboratory is set up, by this contract, to analyze event-driven (Coma! Springs flow falling below 150 cubic feet per second, cfs) samples taken at field sites for common constituents, nutrients, and ~elected field parameters. Common constituents and nutrients (all dissolved) include:

Alkalinity as CaC03, mg/1 Total Hardness as CaC03, mg/1 Calcium as CaC03, mg/1 Magnesium as CaC03, mg/1 Sodium, mg/1 Potassium, mg/1 Chloride, mg/1 Sulfate, mg/1 Fluoride, mg/1 Total Organic Carbon, mg/1 Silica, mg/1 Total Dissolved Solids, mg/1.

Field parameters include: pH, (standard units) and Specific Conductance, (J..ts/cm or J-tmhos/cm) Temperature, (°C) Date and time of sampling Total depth in feet (if a well) Pump or flow period (minutes) prior to sampling Current flow rate in gal/min, or spring flow rate in cfs

One event was sampled between May 28 and May 31, 1996. A second event occurred in September 2000.

A total of 23 wells and springs were sampled in order to establish baseline values for water quality parameters. The data reflect normal water quality conditions, with most parameters remaining reasonably constant and not substantially different from historical values. Readers may contact BAA for data ..

MONITORING RESULTS Monitoring data have been collected and stored in· the EARDC web-based DMB since

·approximately May 1996. In addition to the six sites along the FSZ, an additional groundwater-monitoring site with rain gage was operated near Wimberley with equivalent datalogger instrumentation. The Mt. Baldy well in the Cow Creek limestone of the middle Trinity aquifer is TWDB well number 57-64-705 and includes a pressure transducer for water level sensing. The site was originally established by USGS with assistance from TWDB and has been operated by EARDC since 1998.

Figures 6-11 show graphical results of FSZ monitoring for temperature and specific conductance. Figure 12 shows graphical results of groundwater level monitoring and precipitation at the middle Trinity Mt. Baldy well. Tables .of daily data for all seven sites are presented in.!~e appendices. ·-. '·

All sites show periods of missing record due to instrumentation or cell phone malfunction. Instrumentation outage occurred at some sites, due to the October 1998 flood, and remained out of service for several months while funds were being obtained for repair and re-installation.

In general, FSZ monitoring sites showed a typical seasonal variation in water temperature, generally in the range of 21 to 24 °C. Specific conductance varied with springflow and decreased during times of runoff and floods and tended to increase during droughts at spring sites. Considerable data "noise" exists in the well sites and in the Ezell's Cave site. However, specific conductance generally stayed in the range of about 400-700 J..tmhos/cm at all sites even during the low rainfall year of 1999 when average area annual rainfall was less than 19 inches.

At Ezell's Cave, a DO monitor has been operated but with mixed results due to th~ difficulty of servicing and calibration in an underground environment. Also, planned monthly visits to obtain DO and pH at FSZ sites were suspended when little variation was detected with relevance to FSZ monitoring.

In early 2001, FSZ monitoring sites at Gibbs Sprawl Well and Atascosa Rural Water Supply Well #1 were dismantled; however, the sites at Deep Spring, SWTSU Flowing Well, Comal Springs Run #3, and Mt. Baldy groundwater monitoring well are still in operation under other research programs.
