Mobile Groundwater Remediation & Industrial Water Treatment
North America’s Largest Fleet of Turnkey Remediation Systems
Since 1992, Envent Corporation has served as a Licensed General Engineering Contractor, providing specialized soil and groundwater remediation for the petrochemical, environmental, and construction industries. Whether managing a planned environmental project or a 24/7 emergency spill response, our team delivers the engineering expertise required to meet strict regulatory discharge standards across the United States.
Envent doesn’t just provide equipment; we provide results. Our turnkey approach encompasses the entire project lifecycle, from initial site characterization and system design to permit procurement and final discharge monitoring. We specialize in navigating the complexities of NPDES (National Pollutant Discharge Elimination System) permits and local POTW regulations, ensuring your site remains in full compliance with state and federal environmental laws.
Engineering Expertise in Complex Water Contaminants
Successful groundwater treatment requires more than just equipment; it requires deep engineering experience. Envent’s specialists are experts in treating water contaminated with complex chemical profiles, ensuring site-wide compliance and safety.
We provide proven solutions for:
- Volatile Organic Compounds (VOCs)
We utilize high-efficiency air stripping and granular activated carbon to remove BTEX and chlorinated hydrocarbons. Our systems are engineered to achieve non-detect levels that surpass the most stringent EPA discharge standards. - Hydrocarbons & Oils
Our fleet includes advanced oil-water separators and specialized adsorption media to remediate MTBE and oily water. - Heavy Metals & Solids
We deploy ion-exchange resins and precision filtration to treat heavy metals, asbestos, and total suspended solids. These solutions confirm your effluent meets all aquatic toxicity and turbidity regulations for safe discharge. - Construction Dewatering
Envent manages high-volume water removal at industrial sites using automated, high-flow treatment trains.
Turnkey Groundwater Treatment Systems
Advanced Treatment Technologies
To support compliance with discharge permits, Envent utilizes a multi-stage treatment approach tailored to neutralize diverse contaminants. Our industrial fleet includes:
- Oil/Water Separators & DAF Units
High-efficiency systems for the primary removal of free-phase liquids, fats, oils, and suspended solids. - Air Strippers & Carbon Systems
Advanced stripping and activated carbon technology designed to remove dissolved gases and VOCs to meet 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 verify water is safe for discharge or reuse.
Adherence to Local & Federal Discharge Standards
Industrial water treatment is governed by a complex web of environmental mandates that vary significantly by zip code and industry. Navigating these requirements demands more than just equipment; it requires a deep understanding of the evolving legal landscape. Envent’s engineering team ensures each mobile system is custom-configured to meet or exceed the following regulatory benchmarks:
- NPDES Permit Compliance
We ensure all treated groundwater meets National Pollutant Discharge Elimination System (NPDES) requirements for point source discharge into U.S. waters. - State & Local AQMD/Water Board Rules
Our systems are configured to comply with specific regional standards, such as California’s stringent Water Board requirements or Texas’s TCEQ mandates. - EPA Best Available Technology (BAT)
We utilize industry-recognized Best Available Technology to ensure maximum contaminant removal efficiency for VOCs, heavy metals, and hydrocarbons. - Real-Time Data & Documentation
Envent provides the necessary analytical reporting and flow data required by regulatory agencies to verify that discharge limits are never exceeded.

Sustainable Compliance in Groundwater Management
The effectiveness of a groundwater remediation program is measured by its ability to meet stringent discharge limits consistently under varying site conditions. Envent’s turnkey approach integrates specialized mobile treatment technology with deep engineering oversight to ensure that complex contaminants ranging from VOCs and hydrocarbons to heavy metals and suspended solids are neutralized before they leave the site.
By maintaining the largest fleet of transportable systems in the country, Envent provides the industrial sector with a reliable safeguard against environmental liability. Whether managing high-volume construction dewatering or executing a 24/7 emergency spill response, the combination of licensed technical accountability and over 30 years of field experience allows facilities to maintain 100% regulatory compliance while protecting local community and waterway integrity.
What Our Clients Say
Featured Case Studies
The Problem: A Texas chemical plant’s 10,000-gallon ammonia tank was generating concentrations over 5,000 ppm, exceeding TCEQ odor thresholds and risking residential complaints. Existing carbon systems failed within five days, threatening production shutdowns and massive regulatory fines.
What We Did: Envent deployed the EVAC-3000 mobile wet scrubber, a two-stage packed tower system engineered for high-concentration ammonia. We integrated real-time pH monitoring and NH₃ analyzers into the plant’s SCADA system to maintain >99% removal efficiency and ensure continuous automated safety.
The Result: The system achieved 99% uptime over four weeks, reducing emissions to <10 ppm. The client avoided all NOVs and saved over $50,000 in media and disposal costs compared to traditional carbon filtration.
The Problem: A refinery needed to de-inventory a tank contaminated with Benzene, TOC, Sulfides, and NH3. Standard on-site treatment estimated a two-year timeline, while off-site hazardous waste hauling was cost-prohibitive. Our engineers identified that the high concentration of dissolved solids required a specialized pretreatment approach to protect the facility’s existing infrastructure.
What We Did: Envent performed rapid bench testing and deployed a custom mobile treatment train. We utilized multi-stage oil separation, high-capacity filtration, and specialized polishing media to validate effluent quality for the facility’s system. This turnkey setup included 24/7 onsite monitoring to maintain optimal flow rates and ensure all chemical dosing remained within strict safety parameters.
The Result: We completed the project in just two months, accelerating the client’s timeline by 22 months. This mobile approach resulted in significant operational savings and avoided the high costs of hazardous waste disposal.
