Download the TGR 25th Anniversary Special Edition Here Dear Trinity Aquifer Users, In the coming year, the Trinity Glen Rose Groundwater Conservation District (TGR or the District) will celebrate 25 years as a groundwater conservation district in the State of Texas. As highlighted in our lead story, the District has remained committed to protecting, preserving, and conserving the Trinity Aquifer since voters confirmed its creation in 2002. Past and present members of the elected Board of Directors have contributed extensive experience in engineering, geology, government relations, finance, and other fields. Today’s Board members continue that tradition and dedicate many hours each year to advancing the District’s mission and long-term success. Throughout the District’s history, the Board and staff have worked together to strengthen data management, deepen technical understanding of the Trinity Aquifer, enhance well-monitoring capabilities, and coordinate with other agencies on well permitting and inspections. Most importantly, the District has collaborated with neighboring groundwater districts to help plan for a secure water future for everyone who depends on the Trinity Aquifer. Protecting our water resources is a shared responsibility. Government agencies play an essential role, but lasting success also depends on public participation. For well over a decade, the District has maintained an ever-evolving website, continually expanding its educational content each year. It has also partnered with organizations throughout Bexar County to provide residents with practical information about water conservation and pollution prevention. Through continued community outreach, the District is working to broaden awareness of the importance of using water resources wisely. Congratulations to the Board members, staff, contractors, partner agencies, and members of the public whose contributions have shaped the District’s success over the past 25 years. Together, we can build on that strong foundation and continue the District’s steady pursuit of excellence in the years ahead. Trinity Glen Rose Groundwater Conservation District Board of Directors Trinity Glen Rose GCD Celebrates 25 Years of Trinity Aquifer Conservation, Preservation, and Protection Celebrating 25 Years of Service Amanda Maloukis Keeping track of water legislation in Austin. Celebrating 25 Years of Service 1/16 Click the photo to watch the slide show. “When I became the general manager of the Trinity Glen Rose District (TGR) in 2006, I worked from home, had a filing cabinet, some pens, blank paper and my own computer,” former TGR General Manager George Wissmann said with a reminiscent chuckle. “We had a big task in front of us but very few resources which is why I always like to give credit to other agencies out there like San Antonio Water System (SAWS), Edwards Aquifer Authority (EAA) and various state agencies for helping us operate while we were getting organized.” Wissmann, who spent 22 years with SAWS before moving to the District, noted that SAWS agreed to do water well inspections and well permitting within the district boundaries. The EAA worked with the District on abandoned wells, some mapping and general groundwater consulting, and the San Antonio River Authority made a financial contribution to starting the District. Those humble beginnings were important to work through because the State of Texas designated the portion of the Trinity Aquifer within Bexar County as a Priority Groundwater Management Area (PGMA). That designation meant that this water resource was considered very important to this part of the State as Bexar County was projected to experience heavy growth and critical groundwater issues from availability to water quality within the following 50 years. So for the past 25 years, TGR has been the governing agency for the Trinity Aquifer located in Northern Bexar County and small portions of Comal and Kendall counties. Wissmann recalled that the first general manager, Marshall Reeder, helped organize the first board of directors who were initially appointed by the Governor of Texas. After their first staggered terms expired, the District held elections for each of the five precincts the district directors represent. Part of the District’s responsibility is to work with other groundwater districts in the same region. In the beginning, the District was part of both Groundwater Management Area 9 (GMA-9) and GMA-10. Due to the limited area the District covered in GMA-10, the State ultimately redrew the GMA boundaries which left the TGR wholly within GMA-9, which covers much of the Hill Country north of Bexar County. “The District is the most densely populated of the other groundwater districts in GMA-9, which also means that there is typically the heaviest withdrawals from the Trinity Aquifer here,” Wissmann explained. “Consequently, it was extremely important for the District to consolidate as much information as possible into a central database regarding the water wells in this area. We also needed a series of monitoring wells to track fluctuations of Trinity Aquifer water levels, and engaged with some engineering companies to begin studying the Trinity Aquifer in our area. All of that early collaboration, research and district infrastructure building helped establish a solid base from which the District could grow and evolve.” The most recent transformation of the Trinity District has occurred under General Manager Amanda Maloukis. Maloukis had extensive water industry experience including serving as General Manager of the Rusk County Groundwater Conservation District in Henderson, Texas. There she was responsible for the overall operation of the groundwater district as well as its water planning and policy development processes. Before leaving for Rusk County she was an environmental specialist using her technical expertise in well drilling, well plugging, water quality sampling. “Over the past few years, the District has focused on operational and technical improvements, such as, database management, field inspections, well registrations and permitting, and a very comprehensive update of the District’s regulatory rules,” Maloukis explained. “We also recently received a Texas Water Development Board grant to help us enhance our monitoring wells network capabilities.” The District closed the past year with several areas of growth and new maintenance requirements in its operations. The collection and housing of well data within the water well management database started up and provided support for a multitude of administrative needs while improving efficiency of District resources. Opportunities to improve data collection and mapping were identified and expanded with board support. As the District’s new rules were implemented, staff guided well owners, producers, and drillers through new requirements with the rules and/or application submittals. Also, updates to the District’s Groundwater Management Plan, which are required every five years, were approved toward the end of 2025. That plan identifies new goals and objectives for the protection, preservation, and conservation of the Trinity Aquifer. “One of those Management Plan goals considers the District’s role in abandoned well plugging,” Maloukis said. “Toward that end, we coordinate much of that work with the Texas Department of Licensing and Regulation to identify and investigate reports of abandoned wells, and with the San Antonio Water System for oversight assistance of well pluggings. The District documents abandoned wells and promotes the plugging of abandoned and deteriorated wells by District Rules, well owner communications and distribution of educational materials as needed.” While the business of operating a groundwater conservation district is a very technical endeavor, part of the responsibility of the District’s is to work with the public in teaching them how they can play a part in protecting the Trinity Aquifer. “One of the largest uses of water, still to this day, is landscape watering,” Maloukis explained. “And with Northern San Antonio continuing to grow its housing market, under George’s leadership, we partnered with the Gardening Volunteers of South Texas five years ago to produce a landscape design show called ‘Go Gardening’ focused on helping homeowners and business owners convert their water-thirsty, mostly turfgrass landscapes into water-saving gardens featuring drought tolerant, colorful Texas native plants. “Year one was our proof of concept start as we produced seven, 30-minute shows which we broadcast on the GVST and TGR websites. With Go Gardening gaining momentum each year, we stepped up our production to 10 shows per year and promotion to include some paid social media outreach. That has delivered solid community awareness about the show and thousands of views each year. We’ve also managed to bring on some other water agencies as sponsors for the show.” Long term water planning typically envisions the future 50 years out. Twenty-five years ago, the Trinity Aquifer was designated as a key water resource for the State of Texas. With the District making continual positive strides over the past two-and-half decades, the outlook for conserving, preserving, and protecting the Trinity Aquifer for future generations does look promising. Historic El Niño Could Bring Heavy Rains and Snow to Texas This Winter The Trinity Glen Rose Groundwater Conservation District (TGR) just received approval from the Texas Water Development Board on a $101,241 grant request that was submitted in March 2026. The funds will be invested in expanding TGR's water well monitoring system. While the District currently collects water level data from its seven monitoring wells, the District is looking to increase monitoring locations narrowing down any data gaps. The expanded network will provide more data to address groundwater management and planning efforts. This project will enhance data collection, quality, and availability of groundwater data through a modernized, integrated monitoring network. As part of the project, the District plans to install modern sensors, pressure transducers, and sonic meters in existing wells and make the data available on TGR's online network. This work will also expand the continuous, real-time monitoring network to improve data collection, detection of rapid water level responses, seasonal fluctuations, and aquifer wide trends. "In addition to this grant helping our District collect Trinity Aquifer groundwater data for our planning purposes, this information will also enhance our joint planning efforts with other groundwater districts," said TGR General Manager Amanda Maloukis. "The backbone of the State's groundwater models which shape water planning are built on field data. So, improvements to our District's data collection system will assist in improving model projections for future groundwater use to assist in conserving, preserving, and protecting our groundwater resources for future generations.” The TGR monitoring well expansion project is expected to begin this year and conclude in the spring of 2028. If you are interested in your well being monitored and have water levels available to you, please reach out to staff at the District office at (210) 698-1155 and we will help you determine if your well is a good candidate. Crunching the Water Numbers on Data Center Expansion Texas is a significant hub for data centers, hosting a variety of facilities that support cloud computing, cryptocurrency mining, and artificial intelligence (AI) infrastructure. The state has seen rapid growth in this sector, driven by increasing demand for digital services. While data centers now consume a small portion of the Texas’ total water supply, some researchers warn that with droughts and population growth, data centers have the potential to help push water supplies to near capacity…especially in drier areas in the state. The Houston Advanced Research Center, an independent nonprofit research organization focusing on sustainability solutions, estimates that existing data centers in Texas used approximately 25 billion gallons of water, or 0.4% of the state’s total water use in 2025. By 2030, this demand could increase up to 2.7% of the total annual water use in Texas. That’s the equivalent water consumption of 1.3 million average U.S. households. In preparation for the 2027 Texas Legislative Session, the Texas House State Affairs Committee members questioned data center developers, energy companies and state grid officials about the amount of water the large facilities use; how they impact noise levels and air quality; and whether residents can expect higher costs when data centers come to their communities. The meetings were held primarily to help lawmakers understand the complexities and issues surrounding the increasing demand for data management. Those who submitted public comments in person and online expressed strong opinions that transparency from data center operators and legislators alike will be key to earning public trust. One citizen carefully summed it up this way, “We are paying attention, very close attention.” Major Data Center Locations Texas has several key regions known for data center activity: Dallas-Fort Worth: The primary hub, hosting numerous facilities. Austin: A growing center for tech and data services. Houston: Significant for its energy resources. San Antonio: Emerging as a notable location for data infrastructure. Here is a link to a website that shows data center locations in the San Antonio region.

GARDENING GO Check out what’s happening in this edition of your favorite landscape show - Go Gardening! Go Gardening Season Five Coming to a Close We’re getting toward the end of Season 5 of the Go Gardening Show. While we have been busy producing landscape design shows for five years now, we want to congratulate TGR on 25 years of managing the Trinity Aquifer for the homes and businesses in Northern Bexar County. The Trinity District stepped up to be the first presenting sponsor when we first got started and has continued to support our mission each year since. Thank you! We hope our partnership continues far into the future. Now, on to the show! Fall is a great time to plant those beautiful Texas native plants you’ve been seeing pop up all over San Antonio. This time of year, the ground is still warm enough for roots to establish a good base for growth. As spring rolls around next year, your flowering, drought resistant plants will stand out in the crowd. The last few Go Gardening shows for 2026 will focus on the essentials ingredients for converting your water-thirsty landscape to a low-water-use garden. You’ll learn about compost, landscape design, beneficial pollinators to plan for and much more. So please make use of our pleasant fall weather to “get out there and garden and save some water!” Go Gardening's mission is to help people conserve water in the Edwards and Trinity Aquifers by teaching homeowners how to convert turfgrass areas to low-to-no water use landscapes featuring native plants.

TGR's Drought Tolerant Plant Picks Having a water-saving garden doesn’t mean you have to sacrifice color in your landscape. Here are two great suggestions to consider. Photo credit: Lee Page, Lady Bird Johnson Wildflower Center Zexmenia, Wedelia acapulcensis var. hispida, a well-behaved, hardy perennial produces bright blooms of deep yellow/orange. Often growing up to 2.5 ft in height, it will gradually increase in circumference and spread horizontally from year to year. Zexmenia handles our Texas summer well, often being one of the few flowers you will find along our Hill Country roadsides in the heat of July and August. Even better, its rough foliage is not particularly favored by deer. Water use is very low, once established, and is a larval host plant to our Bordered Patch butterflies. Photo credit: Susan Schroeder, Lady Bird Johnson Wildflower Center Evergreen sumac, Rhus virens , is a sizable shrub to small tree found throughout the Hill Country. Friedrich Wilderness Park in northern Bexar County has many lovely examples lining many of the trails. Not a true evergreen, evergreen sumac will retain its leaves through the winter, drop them, and quickly replace them behaving much live our live oaks, but at a much smaller scale. The female plant produces white clusters of flowers and later fuzzy red clusters of fruit that the birds will enjoy. BRIEFS NEWS TGR Recognized for Texas 4-H Ambassadors Support The Trinity Glen Rose Groundwater Conservation District was recently recognized for its continued support of the Texas 4-H Water Ambassadors Program. The program debuted in 2017, and for the 2025-26 Leadership Academy tours, more than 100 students will be participating. Students travel throughout Texas to learn how water is collected, conveyed, treated, conserved and managed to meet Texan’s needs. Today, more than 40 groundwater districts sponsor Texas 4-H activities and training programs and have been a primary source of funding for the program since its inception now contributing nearly $100,000 per year, which is approximately half of the program’s total donations. To reinforce knowledge gained during the program, water ambassadors pass on that information to others as they engage in various education and service activities throughout the year. This program also provides a platform for youth to connect with water industry professionals and educators who represent a wide range of water disciplines.

TGR Fall is the time for new plants in your landscape… Fall in South Texas is the perfect time to get those water-saving Texas native plants in the ground. The soil is still relatively warm and will help your new plantings develop a healthy root system to withstand cold weather and be ready to show off their color next spring. Native Landscape Guide Available to Download As the Hill Country, which includes parts of Northern Bexar County, continues to grow, so does the need to change the mindset of how landscapes should look for Hill Country homes. While there are many great resources, including the Trinity Glen Rose District’s own Go Gardening Show, we think this particular landscape guide provides a concise strategy for installing a beautiful native plant landscape. The Hill Country Alliance partnered with the San Antonio Water System, Native Plant Society of Texas, and Native American Seed and developed “Native Landscaping Templates for the Hill Country” to help homeowners transform their lawns into native, water-wise landscapes. These well-designed templates offer simple, scalable examples that show the common principles for helping residential landscaping shift away from water-hungry turf lawns towards drought-tolerant native landscaping. Great Water Conservation Tip - If you are thinking about converting your lawn to a native landscape, it may be a good time to rethink your irrigation system. If you are using native plants and planting them at the right time of year, you may be able to do away entirely with in-ground irrigation. The savings can be great for both your water use and your bill. Get the HCA Guide Here . The Hill Country Alliance and Native Plant Society will be holding a webinar on June 16 to go through this landscape guide. You can learn more about the webinar and register at this link .

Go Gardening is also made possible through our co-title sponsor Edwards Aquifer Authority and San Antonio River Authority. You can now watch those Episodes on GVST's YouTube channel. Go Gardening Show - Season 5 - Episode 9 Welcome to Season 5 of the Go Gardening Show! This month's Go Gardening Show brings you some great information about landscape planning in the fall, and most importantly, some great information on compost and plants for pollinators. First up...the Go Gardening crew took a tour of the new Texas A&M AgriLife Extension Service offices. AgriLife is a unique education agency that has been a major supporter of people using more Texas native plants in their landscapes. Not only do these types of yards use way less water than a turfgrass version, but they are better for the environment and wildlife that live here. The highlight of our tour was learning about the various types of bees that thrive at the AgriLife campus. You'll be impressed with the new digs. Next, we visited the Alamo Heights Community Garden to learn the ins and outs of composting. There we spoke to a Mission Compost community education specialist and he gave us a very thorough lesson on how to create your own compost at home. Most people probably have a vision of large scrap piles in their back yards, but we saw a nice enclosed device that makes composting much easier. We also learned that you can drop off your bags of leaves at this site where they are put to good use. Go Gardening's mission is to help people conserve water in the Edwards and Trinity Aquifers by teaching homeowners how to convert turfgrass areas to low-to-no water use landscapes featuring native plants.

Looking for water data? You've come to the right place. You can find water well locations and data at this page. WATER WELL INFORMATION Water Quality Testing of Your Well Safe drinking water for you family and friends relies on frequent testing Because no federal, state, or local entity ensures the safety of private well water, the responsibility for monitoring it falls to the well owner. The District recommends annual sampling of the well with a local lab to monitor the quality of your water. Baseline water quality results are important to have on record in the event a water quality event occurs. Water Quality Testing Basics You will need to find out the quality of the water in your aquifer. Some information about the aquifer water may be readily available from public utilities and water companies. They are required by federal and state law to report water chemistry to consumers. (TGR link for Trinity Aquifer water quality.) Contact the water utility for a copy of the water quality report for information about local water quality issues. However, water quality information on exempt household wells is not recorded or made available through any public agency unless the well owner has given permission. Have your water tested whenever: You suspect it may be contaminated. If you notice a change in color, taste, or odor of the water. The pump or well has undergone maintenance recently. People who drink the water have experienced a change in health, especially stomach-related illnesses. The well water is cloudy or smelly, or tastes bad, it probably does not conform to drinking water quality standards. If you live near oil and gas fields, you should have the water screened for non-refined hydrocarbons in addition to annual testing for coliform bacteria, nitrate, and total dissolved solids. Maintain Water Quality Testing Records To protect your water supply, you need to keep records on each well, manage potential sources of contamination, and test your water at least once a year. Record the location of all wells on your property, and keep a file on each well. Each well will have a unique identification number assigned by the driller. Use this number to track historical information, which may be available from the following sources: Texas Water Development Board Groundwater Database: Licensed water well drillers must submit reports to the state for each well they drill. More than 130,000 wells have been recorded in the TWDB groundwater database since 2001.

Like other wells, an abandoned well is a direct conduit from the ground surface to the aquifer below. Contaminants that enter the well move directly into the aquifer. If a concentrated chemical enters a well, it may move into the aquifer and threaten human health and the environment. It can also put other wells at risk for contamination, particularly those on the same property or those close to the abandoned well. Before you begin the process of plugging an abandoned well, a plugging application must be submitted to the District first for authorization. Please contact the District Office for more information and see our Rules, Forms, & Fees page for the Notice of Intent to Drill, Modify, or Plug. You will need to hire a licensed water well driller or pump installer to seal and plug the abandoned well. Major Flooding Can Contaminate Private Water Wells Large flood events, which the Texas Hill Country is prone to, can contaminate your private water well. However, disinfection can eliminate or reduce harmful bacteria, viruses, or other microorganisms that may be found in your drinking water after flooding in your area. If your well system is damaged, the following instructions for the disinfection process will not work. An indication that your well is damaged can be a decrease in water pressure once turned on. Contact a certified well or pump contractor for examination. It is extremely important to not use contaminated water for: drinking, cooking, making ice, bathing in any form, washing clothes or dishes. After a flood, ingesting or being exposed to contaminated water can cause illness. If you think your well system may be contaminated, some alternative options for safe water include: using bottled water, boiling water for five minutes, using water from a source you know is not contaminated. If your water well was subject to flooding, give the Trinity Glen Rose District a call for assistance in mitigating your flooded well (210-698-1155).
