MOBILE GROUNDWATER REMEDIATION & INDUSTRIAL WATER TREATMENT IN DALLAS

Why Do Dallas-Area Facilities Rely on Our Remediation Fleet?

 We have worked in soil and groundwater remediation since 1992, supporting construction, petrochemical and environmental sites across the country, including projects in the Dallas area. Our field teams handle both scheduled remediation programs and emergency spill situations, and each project moves through the same technical review regulators expect before a discharge plan gets approved. Operating under the same federal and Texas state framework that governs remediation work in Dallas means our crews already know the paperwork and the field requirements a local site will face. That background, backed by the largest mobile water treatment fleet in North America, is part of why operators bring us in for work that needs to hold up to inspection.

Equipment alone does not close out a remediation project, so our scope covers everything from the first site assessment and system design work through permit coordination and discharge monitoring at closeout. Dallas clients get one point of contact across that full timeline instead of managing separate vendors for each phase. We work within NPDES permit requirements and local publicly owned treatment works standards, and each project plan is built around what a specific site is required to meet. Handling the compliance side alongside the field work is what keeps a project on track instead of stalled waiting on paperwork.

It’s always a pleasure to work with your team. From degassing through refloating the internal roof, the planning and field execution were outstanding. The crew got set up fast, and the technicians are always kind, polite, and deliver an amazing service. We look forward to our next project with you.

What Contaminants Can Our Groundwater Treatment Systems Handle in Dallas?

Groundwater at an industrial or construction site rarely carries just one contaminant, and our teams size up that chemistry before any equipment gets deployed. Years of field experience across mixed contaminant sites shape how we match a treatment method to what the water actually contains, keeping each project aligned with the compliance and safety standards it has to meet.

Mobile Wastewater Treatment

We provide proven solutions for:

  • Volatile Organic Compounds (VOCs)
    We use air stripping and granular activated carbon to remove BTEX compounds and chlorinated hydrocarbons from groundwater. Our systems are engineered to meet strict EPA discharge standards for these compounds.
  • Hydrocarbons & Oils
    Our fleet includes oil water separators and adsorption media suited for MTBE and oily water conditions.
  • Heavy Metals & Solids
    We deploy ion exchange resins and precision filtration to treat heavy metals, asbestos, and total suspended solids, built to help your effluent meet the aquatic toxicity and turbidity limits set for discharge.
  • Construction Dewatering
    We manage high volume water removal at industrial sites using automated, high flow treatment trains.

How Do Our Turnkey Groundwater Treatment Systems Work in Dallas?

We run one of the largest mobile remediation fleets in North America, with systems built to handle a wide range of flow rates depending on site needs. Our units are skid-mounted for fast deployment and can be configured around a site’s specific chemistry and flow conditions. Because we manage the full water treatment lifecycle ourselves, from engineering and mobilization through operation and compliance monitoring, Dallas clients are not left coordinating separate contractors for each stage.

Refinery Sector Rule

What Advanced Treatment Technologies Do We Use?

To support compliance with discharge permits, we apply a multi-stage treatment approach built around what each site’s contaminants actually require. Our fleet includes:

  • Oil/Water Separators & DAF Units
    Systems built for the primary removal of free-phase liquids, fats, oils, and suspended solids.
  • Air Strippers & Carbon Systems
    Stripping and activated carbon technology built to remove dissolved gases and VOCs to strict standards.
  • Specialized Filtration
    Multi-stage polishing using clay filters, selective resin beds, and fine-particulate cartridge filtration for high-purity results.
  • Chemical Treatment Units
    Precision dosing systems for pH adjustment, flocculation, and coagulation to help water meet discharge or reuse requirements.

How Do We Meet Local and Federal Discharge Standards in Dallas?

Industrial water treatment sits under a mix of federal, state, and local rules that shift depending on where a site sits and what industry it serves. Meeting those rules takes more than equipment on site, it takes an engineering team that tracks how the requirements change. Our team configures each mobile system around the regulatory benchmarks below, including the ones specific to Dallas and Texas.

Specialized Engineering Consultants
  • NPDES Permit Compliance
    We work toward keeping treated groundwater in line with National Pollutant Discharge Elimination System (NPDES) requirements for point source discharge into U.S. waters.
  • TCEQ Discharge Standards
    Our systems are configured to align with Texas Commission on Environmental Quality (TCEQ) requirements, the state agency that governs industrial water discharge for Dallas-area facilities.
  • EPA Best Available Technology (BAT)
    We use industry-recognized Best Available Technology methods aimed at strong contaminant removal efficiency for VOCs, heavy metals, and hydrocarbons.
  • Real-Time Data & Documentation
    We provide the analytical reporting and flow data regulatory agencies require, so a site has the records needed to stay accountable for discharge limits.

Why Do Terminals and Refineries in Dallas Trust Us?

Petrochemical terminals and refineries have no room for technical mistakes or regulatory gaps, and that reality shapes how we run every project. Over 3 decades of work in mobile groundwater treatment and industrial dewatering, including projects with Dallas-area operators, sits behind that approach.

  • 30+ Years of Experience
    Our remediation work across the petrochemical and utility sectors goes back to 1992. That length of field time is what informs how we handle complex site conditions today.
  • Specialized Mobile Treatment Systems
    Our mobile treatment equipment is purpose built for industrial remediation and dewatering work. Each system can be set up around different contaminant profiles and flow conditions without losing sight of regulatory compliance or operational efficiency.
  • Positioned for Emergency Response
    Our fleet of portable systems ranks among the largest in North America, kept staged so we can reach environmental emergencies without delay. Once on site, our response teams focus on cutting spill risk and keeping downtime short.
  • Safety Record
    Strict health and safety protocols carry through every project we run, backed by a 0.0 TRIR safety record, including work in hazardous H2S environments.

How Do We Measure Success in Groundwater Compliance?

That reputation only holds up if the results hold up too, and a groundwater remediation program is really measured by whether it meets discharge limits consistently, not just once. Our turnkey approach pairs mobile treatment technology with engineering oversight aimed at neutralizing contaminants ranging from VOCs and hydrocarbons to heavy metals and suspended solids before they leave a site.

Our fleet of transportable systems, among the largest in the country, gives industrial clients a dependable way to manage environmental liability on site. Whether the job is high-volume construction dewatering or a fast-moving spill response, that combination of technical accountability and over 30 years of field experience is what helps facilities stay in line with regulatory requirements while protecting the surrounding community and local waterways, including those in the Dallas area.

Featured Case Studies

Flare Gas Scrubber System

The Problem: A Northern California refinery had an MTBE plume from a historic transfer line leak, threatening to reach San Francisco Bay. The site needed continuous containment along with treatment for both groundwater and soil vapor.

What We Did: We designed and have operated a dual-phase extraction and vapor destruction system on this site since 2008, using a liquid ring blower, a knockout tank and moisture separator, and a thermal oxidizer built for MTBE and BTEX. Groundwater is treated on site to meet discharge limits.

The Result: The plume has stayed contained since 2008, with stack samples consistently non-detect for MTBE and BTEX. Over fifteen years of operation, the site has removed a substantial amount of MTBE and petroleum hydrocarbons from the groundwater.

Turnaround Support Services

The Problem: A West Texas crude terminal accumulated a large volume of contaminated stormwater and process water in frac tanks after heavy rains and tank cleaning work, carrying VOCs, benzene, oil and grease, and suspended solids. The terminal needed to discharge to the municipal storm sewer under a new individual NPDES permit but had no treatment capability on site. Off-site disposal would have taken months, and the terminal faced a tight schedule before the next rain event.

What We Did: Our engineers wrote and secured the individual NPDES permit with TCEQ and EPA, then built a mobile treatment setup on site. Water moved through a temporary pipeline into oil and water separation and suspended solids treatment, followed by dual activated carbon vessels for VOC and benzene polishing, with composite sampling and on-site lab checks before discharge.

The Result: We treated the water on site, bringing benzene down to non-detect levels and keeping oil and grease and suspended solids well under the permit’s discharge limits. The terminal’s tanks were back in service before the next rain event, with no spills, no odor issues, and no community complaints.

What Dallas Facilities Want to Know About Groundwater Remediation and Treatment

Do you provide groundwater remediation services in Dallas?
Yes, we provide mobile groundwater remediation services to industrial and construction sites across the Dallas area. Systems are configured on site around each location’s contaminant profile rather than using one fixed setup. Our scope runs from initial site assessment through discharge monitoring.

Yes, we treat PFAS, PFOA, and PFOS contamination at Dallas-area sites using filtration media built for these compounds specifically. These substances behave differently than standard VOCs, a distinction the EPA’s PFAS program outlines in more detail, and require a different treatment approach. Our systems are configured around the specific PFAS profile found at a given site.

Yes, every Dallas-area project starts with a review of site conditions and contaminant chemistry before equipment gets deployed. This assessment is what shapes the treatment method used on that specific site. Skipping this step is part of why generic, one-size setups often fall short on complex sites.
Yes, we provide the analytical reporting and flow data regulatory agencies require for Dallas-area discharge permits. This documentation gives a facility the records needed to demonstrate compliance during an inspection with TCEQ. We handle this reporting as part of the project rather than as a separate service.
Yes, our field teams respond to both planned remediation programs and unplanned contamination events at Dallas-area sites. Mobilization begins once the scope of the site is understood. We handle emergency and scheduled work through the same technical review process.

We serve refineries, petrochemical facilities, construction sites, and other industrial and remediation operators across the Dallas region. Each industry tends to bring a different contaminant profile, from petroleum hydrocarbons to heavy metals to PFAS compounds. Systems are configured around what a specific site actually needs treated, not a standard package.

We maintain one of the largest fleets of portable remediation systems in North America, positioned to reach sites across the Dallas region. Equipment is configured ahead of arrival based on what’s already known about a site’s contaminants. Treatment can begin without a lengthy on-site build-out once the system is in place.
Yes, groundwater and soil vapor contamination often occur together at the same site, and we treat both when a project calls for it. Combining the two avoids managing separate contractors for related problems. Each system is still configured around that site’s specific chemistry.
Yes, we provide monitoring and reporting support after treatment to confirm a site continues to meet its discharge requirements. This is especially relevant for facilities operating under a long-term NPDES permit. Monitoring frequency depends on what the specific permit requires.
