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.
They provided timely communication and, with the support of their teams, contributed to a safe Turnaround. Their quick response to events helped us maintain our commitments to safety and the environment. I would not hesitate to recommend them to lead crews on other jobs.
They deliver exceptional performance, over and beyond our expectations contractually.
Based on this experience, I am comfortable recommending Envent Corporation for any degassing, vapor control, or related services. Their technical capability and consistent performance make them a dependable service provider.
Envent Corporation completed their scope ahead of schedule and under budget. Their planning, resource management, and execution met the needs of the project.
Safety remained a consistent focus during the project. Envent Corporation’s approach to identifying and addressing potential risks contributed to a safe work environment for personnel.
Envent Corporation mobilized promptly and reached the required degas threshold within 18 hours of startup, prior to any tank washing or cleaning.
Envent Corporation demonstrated professionalism and provided reliable engineering and operational support throughout the job.
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.
We provide proven solutions for:
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.
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:
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.
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.
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.
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.
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.
A closer look at how we approach contaminated water and groundwater challenges across different site conditions.
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.
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.

Environmental compliance is not something a site can leave to chance, and our engineering team is ready to build a treatment plan around your site’s specific chemistry and flow needs. Over 30 years of field experience shapes how we approach that plan, aimed at keeping a Dallas-area project on schedule and in line with regulatory requirements.
