Collectively, INTEX Environmental's technical staff represents experience in almost every area of the environmental field.

INTEX Environmental's staff also includes Environmental Technicians specially trained in data collection; monitor well and soil boring installation; and remediation system construction, operation, and maintenance. In addition, INTEX Environmental employs Draftsmen, CADD Operators, and Technical Editors expert in the publication of timely and accurate reports.

INTEX Environmental maintains an extensive stock of vehicles, tools, pumps, surveying equipment, sampling supplies, and monitoring instruments (photoionization detectors, organic vapor analyzers, interface probes, etc.) to support the company's field activities. If an item is needed that is not in stock, INTEX Environmental has the ability to lease equipment on short notice.

For a sampling alternative, INTEX Environmental owns two GeoProbeŽ units (truck-mounted hydraulic drive drills) which can quickly and efficiently collect soil, soil gas, and groundwater samples. These units are particularly useful as an initial screening method in site investigations to quickly assess the presence/extent of a contaminant plume without the expense of multiple drilling phases and unnecessary monitor well installations.

INTEX Environmental owns a variety of highly mobile geophysical equipment including electrical resistivity sets, proton precession magnetometers and gradiometers, electromagnetic units, seismic units, ground penetrating radar and microgravity units, and downhole equipment.

INTEX Environmental's demonstrated ability to address environmental issues from initial investigation to final remediation is based on a foundation of technical expertise with a sharp focus on client satisfaction.

INTEX Environmental has developed and implemented innovative strategies and environmental solutions for a wide variety of clients, including large oil companies; general industry; private businesses and individuals; engineering firms and Federal, State and local government agencies.

INTEX Environmental is one of the few environmental technology companies capable of successfully completing a project from the initial Environmental Assessment to full Remediation and Closure.

King of Prussia, PA
INTEX Environmental was contracted to perform a detailed hydrogeologic investigation at the Henderson Road NPL Superfund site. The site is underlain by cavernous limestone which considerably complicated the investigation. The investigation proceeded in several phases, starting with the cleanout of a former hazardous waste injection well. Eventually, a total of 10 soil borings to depths of 100 feet were installed. Thirty-three monitoring wells, ranging in depth from 100 to 500 feet were installed. Additional investigative methods consisted of surface and downhole geophysics, downhole television camera scans, long- and short-term pumping tests, and quarterly well monitoring.

Harrison, NJ
This site investigation at a former foundry was performed under the New Jersey ISRA program. Upon approval of a Workplan by the NJDEP, the investigation commenced. Numerous surface soil samples and deep soil boring samples were collected to investigate the various areas of concern, including underground storage tanks (USTs), drum storage areas and a layer of foundry sand that had been used as backfill. Nine groundwater monitoring wells were installed to investigate for lead leaching from the foundry sand and to track volatile organics entering the site from the upgradient direction.

Phase I Investigations, Various States
INTEX Environmental was contracted by a national bank to perform Phase I Environmental Assessments on 19 industrial locations owned by a company that had applied for a refinancing loan. The sites were widely dispersed in the northeast, southeast, midwest and southwest. The assessments were required to be completed in a rapid time frame, so multiple field teams were mobilized to each geographic area, while an office crew conducted data base searches and report preparation. Reports on all 19 locations were delivered on time.

Hazelton, PA CERCLA Site
INTEX Environmental was contracted to perform a remedial investigation around a facility where a release of volatile organics had contaminated neighborhood wells. Upon approval of a Workplan by the USEPA, the investigation began. The investigation consisted of 9 sets of triple nested wells ranging in depths from 30 feet to 90 feet. Well installation was followed by a series of pumping tests, piezometer tests and well sampling events. Upon completion of fieldwork and analysis of data, a remedial investigation report was submitted to the USEPA.

Schuylkill Co., PA RCRA Site
INTEX Environmental was contracted to perform a RCRA Facility Investigation (RFI), Risk Assessment and Corrective Measures Study at a manufacturing facility under a USEPA RCRA Consent Order. Upon approval of an RFI Workplan, the investigation commenced. The investigation consisted of numerous surface soil sampling at several areas of concern, and the installation of 12 monitoring wells, some which were nested wells, to depths of 180 feet. Several pumping tests were performed on the wells prior to their sampling.

The data from the RFI was used to prepare an RFI report, Fate and Transport Assessment and Risk Assessment. These reports were then used to prepare a remedial design which consisted of a two well pump and treat system. Upon approval of the remedial design, the system was installed by INTEX Environmental.

Philadelphia, PA Superfund Site
INTEX Environmental was contracted to perform the project management for the demolition of a portion of a chemical factory that had been damaged by an explosion and fire. INTEX Environmental provided on-sight project management, manpower and equipment to complete the demolition and removal action. At the completion of all site work, INTEX Environmental performed confirmatory sampling and provided a final report to the USEPA.

Bucks County, PA
INTEX Environmental provided geologic and hydrologic expertise to the Bucks County Planning Commission for the preparation of a zoning manual designed to minimize building hazards and groundwater degradation in areas underlain by limestone bedrock. The manual is available to town/township zoning and code officials throughout Bucks County.

Northern and Western PA
A study of available mine subsidence information obtained from PADEP was conducted to generate a prediction model for future subsidence events. The study evaluated over 25 factors correlating subsidence to geologic overburden and topographic and bedrock characteristics. The result of the study was a user-friendly, interactive computer program to be used by the State.

Ft. Dix, NJ
INTEX performed ground penetrating radar (GPR) and metal detection surveys to locate a total of 144 underground storage tanks (USTs), associated piping, and nearby utilities distributed across the base.

New York State
INTEX was retained by a NYSDEC contractor to perform geophysical investigations at 19 inactive hazardous waste sites throughout the state. A wide range of geophysical techniques were used, including magnetometry, electrical resistivity, electromagnetics, seismic refraction and ground penetrating radar. The purpose of the surveys were wide ranging, including searching for buried drums and tanks, screening drilling and boring sites, mapping potential contaminant plumes and outlining the borders of landfills.

Central PA
INTEX Environmental was contracted by a local utility company to perform an electrical resistivity survey around the perimeter of a landfill and leachate lagoon. The survey was performed to target two depths below the water table. The survey accurately identified and mapped a leachate plume emanating from the landfill and trending toward a nearby stream.
