Preserving and Improving Water Quality
An overview of how the TCEQ defines, measures, evaluates, and manages the quality of surface waters in Texas.

On this page:

Monitoring

The TCEQ monitors the quality of surface water to evaluate physical, chemical, and biological characteristics of aquatic systems. Water quality is monitored in relation to human health concerns, ecological condition, and designated uses.

The same methods must be used by everyone collecting water samples, using reliable procedures that yield repeatable results. This allows for comparison of data collected by different organizations.

Routine Monitoring Sites

The TCEQ assessed data from more than 3,200 stations (98% of active sites) to develop the 2016 Integrated Report of Surface Water Quality, which describes the condition of waterways throughout the state and identifies impaired waters.

 

Continuous Monitoring Sites

The TCEQ continuously monitors water quality parameters at stations in selected watersheds throughout Texas.

In 2019, there were approximately 35 active continuous water quality monitoring stations throughout the state.

Coordinated Monitoring

TCEQ partners with numerous organizations to develop a statewide monitoring schedule that includes approximately 1,800 active sampling sites.

The schedule is coordinated statewide by the TCEQ. Every spring, approximately 20 meetings are held all over the state to plan monitoring for the upcoming fiscal year.

Coordinated monitoring makes data collection more efficient by leveraging limited funds. Advantages of coordinated monitoring include:

  • Eliminating duplication of effort, thereby saving resources.
  • Increasing local participation in setting priorities and planning solutions.
  • Ensuring consistent data quality for decision making.

 

Clean Rivers Program

Established in 1991, the Clean Rivers Program (CRP) is a very successful partnership between the TCEQ, regional water authorities, and the public.

Fifteen regional water authorities manage the program in 23 river and coastal basins.

Within each basin, the CRP partners implement the program by coordinating and conducting water quality monitoring, assessment, and stakeholder participation in order to improve the quality of surface water.

CRP partners collect more than 60% of the water quality data used by TCEQ.

Standards and Assessment

In order to protect water quality, we must first define and measure it. So we first define standards. A water quality standard is the combination, or pairing, of a use and associated criteria. Uses are the purposes for which the water should be suitable. Criteria are the indicators used to determine whether quality is good enough to support the uses.

Measuring water quality requires reliable, consistent, quality-assured data. Those data are collected and shared through the SWQMIS—the Surface Water Quality Monitoring Information System.

Every two years, we report the status of Texas’ natural waters, based on historical data, in the Texas Integrated Report of Surface Water Quality.

The Surface Water Quality Monitoring Program assesses data from all waters throughout the state to evaluate attainment of water quality standards. The total amount of area assessed for each type of water body depends on the amount of data collected within the specified time frame of assessment for the Integrated Report.

Areas Assessed in Texas in 2016

  • 22,000 stream miles
  • 2,260 square miles of reservoirs
  • 2,550 square miles of estuaries
  • 9.6 square miles of recreational beaches

To fulfill the water quality data needs for Texas, the TCEQ has conducted more than 20,000 routine sampling events since 2008.

 

Site-Specific Standards

TCEQ continues to improve techniques and protocols for assigning tailored, site-specific uses.

 

Data Management

The TCEQ’s Surface Water Quality Monitoring Information System (SWQMIS) is used to store, manage, and make publicly available water quality monitoring data from across the state. More than 20 separate organizations, including river authorities and local, state, and federal agencies, report data to SWQMIS.

In an average year, the Data Management & Analysis Team:

  • Verifies, validates and/or loads more than 450,000 sample results.
  • Creates 100 new monitoring stations in SWQMIS.
  • Trains more than 30 new SWQMIS users.
  • Manages over 34.6 million sample results and related metadata.

Permitting

The state uses several strategies to protect rivers, lakes, and bays. One of those strategies is regulation of stormwater and wastewater discharged to natural waters through permits. Texas' collection of rules, guidelines, and permits is called the Texas Pollutant Discharge Elimination System.

In 2017, the TCEQ began implementing the federal Electronic Reporting Rule by requiring the electronic submittal of permit applications for stormwater general permits. This requirement started on September 1, 2017 for the Multi-Sector General Permit regulating stormwater discharges from industrial facilities, and on September 1, 2018 for the Construction General Permit regulating stormwater discharges from construction sites. Applications available online through the TCEQ's electronic permitting system (ePermits), making it faster and less expensive for both dischargers and the TCEQ to process Notices of Intent (NOIs), Notices of Termination (NOTs), Notices of Change (NOCs), and Low Rainfall Erosivity Waiver (LREW) requests.

  • Electronic permitting has increased efficiency and timeliness in issuing wastewater and stormwater authorizations.
  • Permittees receive coverage faster and are eligible for reduced fees when they use the ePermits system.
  • As a result, usage of this system has increased significantly over time.

 

Working with EPA to reduce the number of objections and delays in permit issuance

Water Quality Division continues to work with EPA to reduce the number of objections received on draft wastewater discharge permits and to reduce the amount of time it takes to receive EPA approval. The number of objections TCEQ has received on draft permits over the past year has been reduced from 48 in 2017 to 14 in 2018. WQD and EPA are using email communication and transmitting permit files electronically to expedite the permit review process.

Restoration

When protective strategies are not sufficient to keep natural waters clean enough for all their uses, we take action to restore water quality.

The Nonpoint Source Program (NPS Program) administers federal funding to help watershed stakeholders address nonpoint sources of water pollution. The program is jointly administered by the TCEQ and the Texas State Soil and Water Conservation Board (TSSWCB)Exit the TCEQ

This program regularly updates a comprehensive Texas NPS Management Program and tracks its progress in NPS Annual Reports.

The primary activities supported by these funds are grant projects to develop and implement Watershed Protection Plans (WPPs).

As of 2019, the total area addressed by WPPs in Texas is approximately:

  • 5,166 Stream Miles
  • 44,196 Acres Reservoir
  • 108,966 Acres Estuary
  • 202,222 Acres Oyster Waters

Each year, the TCEQ uses a process called Request for Grant Applications (RFGA) to award federal NPS grants. The RFGA happens in the summer and awards 2-3 million dollars annually. Awarded projects receive 60 percent of their cost from federal funds. The balance of 40 percent must be matched with state or local funds or in-kind services.

Success Stories

Since 2008, EPA has recognized the success of activities to address NPS pollution which were funded by the TCEQ and TSSWCB. These NPS success stories highlight activities to improve water quality.

 

The Total Maximum Daily Load Program (TMDL Program) works with local stakeholders to improve water quality in watersheds throughout Texas. Stakeholders are actively engaged in water quality restoration activities.

As of February 2019, the total area covered by the TMDLs and associated I-Plans was:

  • 2,483 Stream Miles
  • 28,164 Reservoir Acres
  • 224 Estuary Square Miles

Galveston Bay Estuary Program

Since 2000, the TCEQ’s Galveston Bay Estuary Program (GBEP)Exit the TCEQ

 

The goal of the Conservation Assistance Program (CAP) is to support the GBEP and its partners’ efforts to preserve wetlands and other important coastal habitats to protect the long-term health and productivity of Galveston Bay. The CAP was developed to protect habitat and water quality, reduce flood and storm damage, provide recreational opportunities for residents in the area, and to preserve the region’s unique natural heritage.

The CAP has been associated with 10 successful projects from 2011-2017, conserving approximately 6,119 acres. In addition, there are multiple active CAP projects in the region, which target the conservation of nearly 20,000 acres. Lone Pine Farm and Gordy Marsh are just two examples from this program.

The Ghirardi Family WaterSmart Park, located in the heart of a League City, Texas neighborhood, was completed in the spring of 2014. The project is a partnership of the GBEP, Texas A&M AgriLife Extension’s Texas Coastal Watershed Program, the TCEQ’s Nonpoint Source Program, and the City of League City. This facility is designed to showcase seven different stormwater best management practices (BMPs) appropriate for use at homes or businesses. It includes a green roof, rain gardens, pervious paver parking lot, a rain-water harvesting cistern, a swale, a vegetated buffer, and a compost-on-turf-grass demonstration plot. The park also offers traditional park amenities to the community such as a pavilion, walking trails, and a playground. Researchers with Texas AgriLife Extension conduct testing of the stormwater BMPs to evaluate how effective each BMP is at improving water quality.
