Executive Summary This report documents the results of an exploration of potential brackish groundwater sources for desalination near San Angelo, Texas at the request of the City of San Angelo, the Upper Colorado River Authority, and the Texas Water Development Board. The Permian-age Whitehorse Formation and Clear Fork Group were chosen for exploration based on previous work identifying these formations as potential brackish groundwater sources. In an attempt to investigate a full section of these aquifers and to target areas without established use of this brackish groundwater, exploration areas in eastern Irion and western Tom Green Counties were chosen. Because of the poor water quality in these formations and the existence of fresh water in the overlying Edwards-Trinity Aquifer, there are virtually no existing water wells completed in Permian-age formations in this area, and there is therefore very little existing water quality and production rate information for these formations in this area. Three test sites were chosen, two targeting the Whitehorse Formation in Irion County and one targeting the Clear Fork in western Tom Green County. A test hole was completed at each of the sites. A test well was constructed at only the Clear Fork exploration site in western Tom Green County. As a result of the two exploration test holes in the Whitehorse formation in the area of eastern Irion County, it appears that this formation does not contain water of appropriate quality for desalination in this area. Further, wells completed in the Whitehorse in this area are not likely to produce water at sufficient rates for municipal supply needs. Further exploration in the Whitehorse for a desalination source water for the City of San Angelo is not recommended. The Clear Fork formation in the area of western Tom Green County appears to offer greater production potential than the Whitehorse, although the test well completed in the Clear Fork demonstrated relatively limited productive capacity (about 45 gpm) for municipal supply use for a city the size of San Angelo. There is very little quantitative data regarding the productive capacity of water wells completed in the Clear Fork in this area, so it cannot be determined whether areas of greater production exist in this formation with the current available data. Additional exploratory test holes and test wells might identify areas in this section of the Clear Fork with better production, but there is no guarantee of success with further exploration. The Clear Fork test well produced a brackish water of 3,990 mg/L total dissolved solids, with an estimated desalination yield of 80%. The radium concentration of the produced water was relatively high. The radium appears to be sourced from a particular interval within the well. While this radium is efficiently removed in the desalination process, reduction of the radium concentration through site selection or through well construction controls is desirable in order to ease permitting of concentrate disposal wells.

Introduction This report documents the results of an exploration of potential brackish groundwater sources for desalination near San Angelo, Texas at the request of the City of San Angelo, the Upper Colorado River Authority, and the Texas Water Development Board. The City of San Angelo used an extensive public process to evaluate potential strategies to meet the City's future water needs. In February of 2004, the San Angelo City Council, the Citizen's Water Advisory Board, and City Staff published the results of this process, which identified five preferred strategies. One of these five was to "Identify and develop fresh and brackish groundwater alternatives". The Region F Water Planning Group followed by naming desalination as one of 10 potentially feasible strategies to meet the water supply needs of the City of San Angelo as a wholesale water provider. A descriptive evaluation of this strategy option appears on page 4-197 of the 2006 Region F Regional Water Plan. A previous study (LBG-Guyton Associates, 2005) identified the Permian-age Whitehorse Formation and Clear Fork Group as possible brackish groundwater sources. These formations crop out on the eastern and central portion of Tom Green County, and dip to the west. Figure 1 presents a conceptual cross section of these formations in the San Angelo area. There is some use of the Whitehorse Formation for wells in Coke County and in other parts of western Texas. The Clear Fork group also yields moderate to large quantities of water to wells in eastern Coke and Tom Green Counties. Figure 2 shows the location of wells completed in the Whitehorse and Clear Fork Formations in this area. Neither of these areas, however, represent a full section of the aquifer and wells are generally low-yielding as a result. Further, because these locations are near the outcrop, the water quality is generally better than in downdip locations and therefore both of these locations have established uses of this groundwater. In particular, the Clear Fork wells in eastern Tom Green County are heavily used for irrigation purposes. In an attempt to investigate a full section of these aquifers and to target areas without established use of this brackish groundwater, exploration areas in eastern Irion and western Tom Green Counties were chosen. Because of the poor water quality in these formations and the existence of fresh water in the overlying Edwards-Trinity Aquifer, there are virtually no existing water wells completed in Permian-age formations in this area, and there is therefore very little existing water quality and production rate information for these formations in this area. Numerous oil-field geophysical logs were used to select three test locations during the course of the exploration (Figure 3). Specifications for the exploration were prepared and the exploration drilling contract was awarded to West Texas Water Well Service of Odessa, Texas in a competitive bid process in late 2006. Drilling commenced in April 2007. The initial phase of exploration targeted the Whitehorse Formation at its full thickness in eastern Irion County. The first test hole location in this formation was near the existing artesian well completed in the top

of the Whitehorse. This well had promising production and water quality, and the objective of the test hole near this well was to investigate the full thickness of the Whitehorse at this location. A second location approximately eight miles to the north of the first was chosen with a similar objective of investigating the full thickness and spatial extent of the Whitehorse. After the first two test holes both indicated poor water quality and production rates from the full extent of the Whitehorse, and the formation was found to have similar geologic character in both locations, a third test hole in the Whitehorse was not attempted. Instead, a location was chosen in western Tom Green County to explore a particularly thick section of the Clear Fork Group informally known as the "Clear Fork Reef." Test hole results at this location were promising enough to merit test well construction and testing. The results of these activities are described by location in the following sections. Supplementary data are to be found in the appendices. The dates of performance of various phases of the work at the test sites are given in Table 1.

Parks-1 Test Hole The first test hole (Parks-1) was located on the Howard Parks property near the flowing well tested by LBG-Guyton Associates in December, 2004 (Figure 4). This existing flowing well is cased to a depth of 180 ft and produces from the 180 ft to 202 ft (total depth) interval, which only represents a very small interval near the top of the Whitehorse Formation. The pumping test on this existing well indicated a negative boundary was reached early in the test, and the long-term transmissivity calculated from pumping test data was 4,130 gpd/ft. Water chemistry analyses performed on a sample collected from the existing well indicated the water was saturated with respect to gypsum. Gypsum saturation can pose significant challenges to the desalination treatment process. The Total Dissolved Solids (TDS) result from this sample was 5,160 mg/L. The goal of the 2007 test hole was to explore the full thickness of the Whitehorse at this location. Geophysical and lithologic logs available from historical oil test holes suggested that there was a significant amount of sand in the Whitehorse in eastern Irion County, although no water quality or production information was available from these sources. Test hole drilling was performed with the air rotary method, which has the advantage of allowing an estimate of both production and water quality as the test hole is being drilled. Cuttings were logged at ten-foot intervals, and the entire hole was logged with a geophysical logging suite consisting of gamma, SP, caliper, and resistivity with multiple electrode spacings. Before the test hole proceeded into the Whitehorse, a 16-inch steel surface casing was set to the top of the formation to protect the overlying fresh groundwater from any brackish water below. Unlike the existing Parks well, no artesian flow was observed from the Parks-1 test hole, although the water level in the test hole did rise very slowly to a level near the surface over a period of a few days. The top of the Whitehorse was at a depth of 160 ft at this location, and the test hole was terminated at the base of 790 ft. The Whitehorse in this location is primarily comprised of fine gray cemented sand, with streaks of pyritic dolomite and shale. A photograph of this fine gray cemented sand under 10x magnification is given in Figure 5. When the total depth of the test hole was reached, the hole was pumped by the air rotary drill stem discharge and an informal water sample was collected and analyzed by the City of San Angelo. The analytical results indicate a sodium-chloride type of water with very high (greater than 20,000 mg/L) total dissolved solids (TDS) content that would generally offer low desalination yields. Further, the formation produced at a very low rate from this air pumping, approximately 10 gallons per minute (gpm).

The test hole was plugged by cement placed by tremie pipe under pressure from the total depth of 790 ft to a level inside the surface casing of 150 ft below ground surface. The surface casing was left open to 150 ft in order to allow the landowner the option of making a well by perforating the casing at a shallow freshwater interval. A drawing of the test hole is presented in Figure 6. Appendix A contains the formation sample descriptions, geophysical log, and water sample analytical results.

Schlinke-1 Test Hole The second exploratory test hole (Schlinke-1) was located on the Schlinke property approximately eight miles northwest of the Parks-1 location. A location map is given in Figure 7. As with the Parks-1 location, geophysical and lithologic logs available from historical oil test holes suggested that there was a significant amount of sand at this location, and the Schlinke-1 test hole was drilled to assess the water quality and productive capacity of the Whitehorse at this location. Test hole drilling was performed with the air rotary method, which has the advantage of allowing an estimate of both production and water quality as the test hole is being drilled. Cuttings were logged at ten-foot intervals, and the entire hole was logged with a geophysical logging suite consisting of gamma, SP, and resistivity with multiple electrode spacings. Before the test hole proceeded into the Whitehorse, a 16-inch steel surface casing was set to the top of the formation to protect the overlying fresh groundwater from any brackish water below. The top of the Whitehorse was at 131 ft at this location, and the test hole was terminated at the base of 790 ft. The Whitehorse in this location was found to be very similar in character to the Parks-1 location; it is primarily comprised of similarly fine gray cemented sand, with streaks of pyritic dolomite and shale. When the total depth of the test hole was reached, the hole was pumped by the air rotary drill stem discharge, but the flow was too low (approximately 3 gpm) to clean the hole out for an adequate sample. Field measurement of the discharge indicated a conductivity in excess of 50,000 µS/cm, which is an indication that the water in the formation is of too poor quality to be a feasible desalination source. The production potential is also clearly poor at this location. The test hole was plugged by cement placed by tremie pipe under pressure from the total depth of 790 ft to a level inside the surface casing of 131 ft below ground surface. The surface casing was left open to 131 ft in order to allow the landowner the option of making a well by perforating the casing at a shallow freshwater interval. A drawing of the test hole is presented in Figure 8. Appendix B contains the formation sample descriptions and geophysical log.

Schmidt-1 Test Hole The third exploratory test hole (Schmidt-1) was located on the Schmidt property approximately one mile south of Knickerbocker in western Tom Green County. A location map is given in Figure 9. The purpose of this test hole was to investigate a particularly thick section of the Clear Fork group known informally as the "Clear Fork Reef." An anecdotal report of an historical flowing test hole drilled by cable tools north of Knickerbocker, combined with area geophysical logs, suggested exploration of the formation at this location. Test hole drilling was performed with the air rotary method until a depth of 530 feet was reached. Sloughing from overlying shale into the test hole made mud rotary drilling necessary from that point forward. Cuttings were logged at ten-foot intervals, and the entire hole was logged with a geophysical logging suite consisting of gamma, caliper, SP, and resistivity with multiple electrode spacings. Although no fresh groundwater was encountered during drilling at this location, a 12-inch steel surface casing was set to the base of the Cretaceous at 145 ft to protect this formation from any brackish water below. A large aboveground clay containment structure (approximately 100 ft wide x 100 ft long x 5 feet high) was constructed to contain the brackish waters discharged during all test pumping at this site. Evaporation of the limited amount of water discharged during test pumping made further management unnecessary. The top of the Clear Fork dolomite was at 460 ft at this location, and the test hole was terminated at a depth of 1,031 ft. A small amount of brackish water was produced during air rotary drilling beginning at a depth of 520 ft. Mud rotary drilling prevented estimates of water quality and quantity produced from the test hole for depths greater than 530 ft. The formation samples indicated the Clear Fork is primarily comprised of a tan dolomite with interbedded shale and pyrite. Vugular porosity was evident in many of the dolomite formation cutting samples, particularly in the upper portion of the dolomite. A photograph of one of the dolomite samples under 10x magnification is presented in Figure 10. The dolomite became very hard at a depth of approximately 630 ft, significantly increasing drilling times throughout the rest of the test hole. In order to evaluate the water quality and productive capacity of the test hole, small temporary discharge sections were constructed at three 30-ft depth intervals: 903 ft to 933 ft, 675 ft to 705 ft, and 615 ft to 645 ft. The intervals were isolated and pumped with air at a rate of 10 to 15 gpm. After the drilling fluid was removed, a water sample was collected from each interval and analyzed for selected constituents. The results of these sample analyses are summarized in Table 2. The deepest interval (903-933 ft) produced the poorest-quality water, with a TDS of 65,800 mg/L. The 675-705 ft and 615-645 ft intervals produced better quality water in general, with TDS of 8,140 mg/L and 7,040 mg/L, respectively. All three intervals produced a sodium-chloride type of water.

Based on these results, a test well was constructed by reaming the hole to a depth of 505 ft and setting and pressure cementing a 7-inch steel casing with threaded connections. Monitoring the discharge from the subsequent hole cleanout with air indicated the water quality degraded very quickly below a depth of 700 ft, and therefore cement was placed in the hole under pressure from the total depth to a depth of 687 ft to isolate the well from this poorer-quality water. A drawing of the test well is presented in Figure 11. Appendix C contains the formation sample descriptions, geophysical log, and water sample analytical results. This well was developed over a period of two days. The pumping rate during development was 52 gpm, with a drawdown of 375 ft after 1.5 hours. Based on this information, a constant-rate pumping test was performed at a discharge rate of 23 gpm. This rate ensured the aquifer would be adequately stressed without the risk of the pump breaking suction during the test. The pumping period for the test was 18 hours, with a 12-hour recovery data collection period. The static water level on October 9, 2007 just before the start of the test at 8:00 AM was 51.71 ft below top of casing (BTOC). The casing height above ground surface was 1.60 ft. The drawdown at the end of the 18-hour pumping period was 187 feet, for a pumping level of approximately 239 ft below top of casing. A hydrograph of the pumping and recovery periods is shown in Figure 12. At about 4:00 PM on October 9 a sample valve was opened to fill a sample barrel, resulting in a temporary reduction in pumping head, and therefore an increase in discharge and drawdown. This event had a negligible effect on the test results. Analysis of the pumping test suggests a slightly lower transmissivity in the near-wellbore than farther out into the formation. The estimated formation transmissivity at this location for the 505-687 ft interval is 200 gpd/ft (Figure 13). Assuming a pump setting of 505 ft, the maximum sustained pumping rate for this well is approximately 45 gpm. The production rate from this well could potentially be improved to as much as 75 gpm by the use of well stimulation techniques such as acidization, and in a production situation (such as in a wellfield) these techniques would be recommended to maximize yield from the well. However, at this exploration stage very little if any additional information about the aquifer as a whole would be gained through the use of these techniques. Further, even increasing the yield to 75 gpm would be ineffective for demonstrative purposes. Therefore, given the cost of these techniques they were not recommended. A water sample was collected from the Schmidt-1 test well near the end of the pumping period and submitted for analysis. The results are given in Table 3. The water was a sodium-chloride type of water with a TDS content of 3,990 mg/L. The estimated treated desalination yield of this water is 80%, which is in the upper range of that estimated in the 2006 Initial Feasibility Assessment report (Freese and Nichols and LBG-Guyton Associates, 2006). There was a strong hydrogen sulfide odor in the water. This hydrogen sulfide reacts with the steel casing and produces pyrite if the well is not pumped for a time. The produced water from the formation itself is virtually colorless. The hydrogen sulfide is not expected to effect treatment

yields, but it should be reduced in concentration during treatment for corrosion prevention, aesthetic, and possibly regulatory purposes. The radium-226 concentration is elevated. This radium is probably due to the presence of a black organic shale in the producing interval that exhibited a strong response on the gamma log. Radium is easily removed in the treatment process, but very high radium concentrations in the reject concentrate can require additional treatment to reduce the radium concentration before the reject concentrate can be disposed of in an injection well. The well was completed with a locking cap, and the site was returned to grade. The well may be useful in the future for water level monitoring purposes, but due to elevated levels of dissolved solids, fluoride, radium, and other constituents of concern it is not suitable as a domestic or livestock source without treatment. Caution and perhaps some monitoring equipment should also be used when opening the well casing, as there is a possibility that dangerous levels of hydrogen sulfide could develop inside the closed well casing over time.

Conclusions and Recommendations The Whitehorse formation in the area of eastern Irion County does not contain water of appropriate quality for desalination. Further, wells completed in the Whitehorse in this area are not likely to produce water at sufficient rates for municipal supply needs. Further exploration in the Whitehorse for a desalination source water for the City of San Angelo is not recommended. The Clear Fork formation in the area of western Tom Green County appears to offer greater production potential than the Whitehorse, although the Schmidt property test well completed in the Clear Fork demonstrated relatively limited productive capacity for municipal supply use for a city the size of San Angelo. There is very little quantitative data regarding the productive capacity of water wells completed in the Clear Fork in this area, so it cannot be determined whether areas of greater production exist in this formation with the current available data. Additional exploratory test holes and test wells might identify areas in this section of the Clear Fork with better production, but there is no guarantee of success with further exploration. The quality of the water produced by the Schmidt property test well is treatable by desalination with an estimated yield of 80%. Hydrochemical facies and dissolved solids concentrations are generally not as spatially variable as productive capacity in a consolidated formation, and so the treatability of the water is expected to remain relatively consistent in the Clear Fork in this area. The radium-226 concentration (39.2 pCi/L) is relatively high in waters produced by the Schmidt test well. This is due in part to the fact that the test well was constructed to capture a large formation interval for productivity testing, including some shale intervals that appear to contain high levels of radium. The radium concentration from the test well is such that if this well were used as a production well, the desalination concentrate would be above the limit specified for Class I non-hazardous underground injection (60 pCi/L for Ra-226). Desalination is very efficient at removing radium, so the potential problem with this radium concentration lies in disposal and not treatment. If sufficient productive capacity were found elsewhere in this section of the Clear Fork to demonstrate that it is a feasible desalination source, the radium concentration in the groundwater in that area would need to be determined to address this potential disposal problem. Assuming a desalination yield of 80%, the radium concentration would need to be about 12 pCi/L or less to result in a concentrate level of less than 60 pCi/L for Class I non-hazardous disposal. If elevated levels of radium were found elsewhere in the formation, the radium concentration in the desalination concentrate could possibly be reduced in a wellfield production setting by one or a combination of the following methods:
1. Using existing geophysical logs to identify spatial areas that do not exhibit the characteristics of high radium concentrations. UCRA is currently conducting a study of existing geophysical logs to assess the spatial extent of the radium-rich intervals.

2. Constructing the production well in such a way as to limit the amount of water produced from intervals with high radium concentrations. This would most likely involve setting casing below such intervals, and perforating above them to recover production intervals lost to the casing.
3. Reducing the radium concentration of the injectate through dilution or additional
treatment. Dilution has the drawback of reducing desalination yields and increasing disposal volumes, and additional treatment has the drawback of producing a secondary waste stream that could not be injected into a Class I non-hazardous disposal well.
The primary concerns to be addressed in additional exploration, therefore, are finding greater productive capacity and limiting radium concentrations through site selection or engineering controls, if possible. As for regulatory concerns, recent rulemaking developments promise to make permitting the disposal of non-hazardous desalination concentrate through deep well injection easier. New rules have been proposed by TCEQ that will make permitting of desalination concentrate injection wells much easier and less expensive. These rules should be published for comment in March 2008, with a target adoption date of July or August 2008. The new proposed rules would allow Class I disposal of non-hazardous desalination concentrate by general permit, which will greatly facilitate the authorization of disposal wells. Also included in the proposed rules would be a reduction of the State's technical standards for these wells to standards similar to federal standards for Class I non-hazardous injection wells. Federal standards for Class I non-hazardous wells are similar to Class II well requirements, and Class II operators may elect to obtain a dual permit for Class II and Class I injection of desalination concentrate. Further, only a Texas Railroad Commission permit would be needed for the injection of non-hazardous desalination concentrate for the purposes of enhanced oil and gas recovery. A detailed geophysical log study should be performed to delineate the full extent and thickness of this Clear Fork "reef" structure before any further exploration is considered. Also, geophysical logs should be studied to determine whether the intervals of high radium concentration observed in the Schmidt test well are likely to be a geographically local or more widespread phenomenon. UCRA is currently performing a log study that will complete these formation delineation and radium persistence tasks.
