Lisa Mauser

Austin, Texas ***** - (512) -749-9136

Ms. Mauser is a skilled Lead Industrial Technician with 14-years of experience.

Authorized to work in the US for any employer


Lead Operator

Carlsbad, NM

Gradiant Energy Services (Current employer)

Gradiant provides treated water for the process of fracking in the oil field. Water is pumped from the client’s SWD (Salt Water Disposal) tanks to the treatment system. It goes through a Oil Water Separator where the oil is returned and the water continues through the process. In the 1st mix tank Caustic Soda is introduced to raise the pH, it underflows to the 2nd mix tank where Ferric Chloride is dosed and then to mix tank 3 for Polymer. The combined chemicals cause the solids to drop out in the Clarifier and cleaner water continues over the weir where Hydrochloric Acid is added to neutralize the pH. In the final effluent line Sodium Hypochlorite is added for Bacteria control and is discharged to a hold pond. The water is then reused during the fracking process.

Senior Industrial Wastewater Treatment Technician

Austin, TX

Samsung Semiconductor

Samsung used Ultra-Pure Water in the manufacturing of computer/cell phone memory chip wafers. All water used in the FAB and Ultra-Pure Water Facilities was directed to IWT (industrial Wastewater Treatment) Facility.

Ms. Mauser provided operational oversight and was responsible for the operations of 4 Acid Wastewater Systems which treatment consisted of Caustic or Sulfuric dosing for pH control and combined flow rate of ~ 2,500 gpm, 3 Fluoride Wastewater Systems using 10-35% Lime solution for pH control & polymer. A combined flow rate of ~1,200 gpm. The solid waste was dewatered using 2 large filter presses and hauled off site. 3 Copper Wastewater Systems using 10-35% Lime for pH control, Sodium Bisulfite for peroxide removal, Heavy Metal Removal for metals, Ferric Chloride coagulate and polymer. The solids were dewatered using 2 large filter presses and hauled off site as hazardous waste. A combined flow rate of ~350 gpm. All 3 different system combined at 4 different Outfalls and discharged to the City of Austin.

Lead Industrial Technician - Hazardous Waste Water


Lead Industrial Technician / Project Safety Team Leader under

OSHA and the U.S. Coastguard

Pasadena, TX

Ms. Mauser provided operational oversight at the ExxonMobil Pasadena Project. She was responsible for plant operation, operator training, scheduling outside training, updating JHA's, SOP’s, scheduling weekly safety meetings, planning and conducting emergency action drills, tracking all training required to meet operating contract, LPS stewardship/training, short service worker training and waste management, the contact for client safety audits and all system operations. The ExxonMobil Pre-Injection Treatment Facility (PITF), located in Pasadena, TX, is designed to deliver 1500-gpm (2.25-mgd) of filtered water for disposal using deep-well injection. The site, bordered by the Houston Ship Channel, covers 365 acres and is the largest ExxonMobil remediation facility in the world. Treatment includes collection ponds, transfer pumps, storage tanks, 16 mixed media filtration vessels, 17 cartridge filtration vessels, along with associated pumps and piping. The process is highly automated and acidic wastewater (pH ranging between 1.3 to 2.2 SU) is filtered through the system and injected under high pressure into 2 injection wells to a depth of 7,500 feet.

Apogee Selenium Treatment Facility

Industrial Technician ll / Project Safety Team Leader

Logan, WV


Ms. Mauser was a member of the startup team and was the driving force that established the Apogee Safety Program. She was a role model and instilled the CH2M safety culture in the newly hired operators. She assisted with commissioning and operation of the first of its kind Selenium Water Treatment Plant designed to remove selenium from mine water. The 2,800 gpm (4-mgd) biological treatment process includes a primary treatment of 3 Fluidized Bed Reactors (FBR) that created an anoxic/anaerobic reduction of selenite/selenate to elemental selenium followed by Ballasted Sand Clarifiers (BSC) for the removal of solids generated by the FBR, the final step in the process is an aerobic Moving Bed Bio-film Reactor (MBBR) for removal of residual organics and to increase the dissolved oxygen prior to discharge.

CONSOL Energy Project / Industrial Technician ll / Project Safety

Team Leader

Oakwood, VA


Ms. Mauser was a shift supervisor and responsible for daily operations and process control at the 1600-gpm (2.3-mgd) Buchanan Mine Water Treatment Plant. In addition to her operational duties, she was the safety PSTL responsible for all aspects of safe operations and training related to the site. She led the team of new operators to embrace the Safety Culture. The site had no recordable injuries while CH2M operated the site. She was responsible for leading the team under MSHA regulations and actively met with MSHA inspectors. She conducted daily safety meeting, planned safety drills and presented power point safety training and compliance. She maintained the Health

& Safety Plan, Emergency Action Plan, Spill Prevention Plan, maintained the training matrix and provided the training for compliance. This facility is a state-of-the art Zero Liquid Discharge (ZLD) process and supported CONSOL Energy's Buchanan Mine operations. The facility treats wastewater from an underground coal mine. The processes include lime and soda ash softening, Zenon ultra-filtration, and reverse osmosis to effectively treat mine water for reuse at the off-site coal process facility. Lime sludge is dewatered using a belt filter press and hauled offsite for disposal. Concentrate (brine) generated from reverse osmosis is further processed through a two stage thermal system which includes an evaporator (brine concentrator) and crystallizer. The crystallization stage produces salt crystals which are further processed to separate the crystals and fluid using hydro-cyclones, centrifuges, fluidized-bed dryer, compactor, granulator, and screening equipment that process the crystals into pellets for use as road salt. The plant produces is designed to produce approximately 80 tons of road salt per day.

Penta-Wood Products Superfund Site / Industrial Technician ll /

Project Safety Coordinator/Site Manager

Siren, WI


Ms. Mauser was responsible for the daily operation and maintenance of the 50-gpm groundwater extraction and treatment system at the Penta Wood Products Superfund Site. She successful completed the Safety Coordinator Training. In this position she was responsible for all staff and contractors working at the site. She maintained the Health and Safety Plan, Spill Response, AHA and SOP updates, provided toolbox talks, and supervised Confined Space entries as needed to clean and maintain vessels.

The site is a former wood treatment facility. Several areas of the site are contaminated with arsenic and large quantities of pentachlorophenol (PCP) contaminated fuel oil. The treatment process includes bag filtration, oil and water separation to remove the light non aqueous phase liquid, polymer addition and dissolved air floatation (DAF) unit to remove turbidity, and granular activated carbon (GAC) to remove organics prior to discharge. The treatment system also includes a bio-venting system which introduces oxygen to the production zone to promote aerobic activity. Sludge dewatering is achieved using diatomaceous earth and rotary-drum vacuum system. In addition, Ms. Mauser performed routine maintenance on process equipment, maintained chemical inventories, scheduled hazardous waste hauling, and scheduled changes outs of the GAC filter media.

Ashtabula River Remediation Project

Lisa Mauser

Lead Industrial Technician

Ashtabula OH


The project targeted the removal of over 650,000 tons of sediment from the Ashtabula River. This was at the time the largest and most complex river remediation action taken by U.S. Environmental Protection

Agency (U.S. EPA). Ms. Mauser served as an Industrial Technician responsible for daily operation and maintenance of the 5,000-gpm water treatment plant. The treatment processes involved dredging and removing polychlorinated biphenyl, polynuclear aromatic hydrocarbons, heavy metals, and radionuclide contaminated sediment. The processes included a 20,000 gallon dry polymer batch-mixing system, geotextile tubes, lamella clarifiers, polishing geotextile tubes, horizontal & vertical sand filters, and granular activated carbon (GAC) filters prior to discharge. Ms. Mauser monitored water quality, pH, total iron, chlorine, and other process performance indicators. She maintained chain-of-custody records for weekly, monthly, and quarterly samples. Ms. Mauser performed polymer jar testing, prepared sediment for laboratory testing, and trained new employees. She performed her duties while adhering to strict health and safety site policies.
