ASC’s field personnel are experienced geoscience professionals, who can assist client field personnel in the implementation and interpretation of HRSC technologies. In addition, ASC can provide professional log interpretation, and hydrogeologic/hydrostratigraphic modeling.

Service Area: ASC is a certified small business located in Sacramento, California. ASC’s service area is primarily in the western US, but is capable of mobilizing to provide services wherever our clients may require.

Cascade is the leading provider of environmental drilling, in situ remediation applications, and high resolution site characterization in the United States. Our vision is to integrate technology, safety, sustainability and human potential to tackle the challenging environmental and geotechnical issues facing our clients.

Service Capabilities: Cascade offers a full array of Geoprobe® Direct Image® services including Electrical Conductivity (EC), Membrane Interface Probe (MIP), Low Level Membrane Interface Probe (LL-MIP), Hydraulic Profiling Tool (HPT), Combined Membrane Interface Hydraulic Profiling Tool (MiHPT), and Hydraulic Profiling Tool – Groundwater Sampler (HPT-GW). These services are bolstered by Cascade’s collaborative work plan design process prior to projects, data imaging capabilities using EVS software, and Cascade’s ability to support the planning and implementation of remediation projects.

Cascade operates two NELAP-certified (NY, NJ and FL) and DoD/ELAP-certified mobile laboratories. Groundwater quality profiling and bedrock sampling and analytical services are provided through our WaterlooAPS TM and COREDFN TM technologies, respectively.  

Dakota Technologies provides state-of-the-art products and services for hazardous waste site investigations, specializing in the rapid site assessment of subsurface LNAPL and multi-component DNAPL. We are a leading international service provider of a full and expanding suite of High-Resolution Site Characterization (HRSC) technologies. These technologies are offered on all direct push platforms, including both percussion and cone penetration test (CPT) rigs.

Service Capabilities: HRSC services include

• Ultra Violet Optical Screening Tool (UVOST®)
• Tar-specific Green Optical Screening Tool (TarGOST®)
• Dye-enhanced Laser Induced Fluorescence (DyeLIF™)
• Hydraulic Profiling Tool (HPT)
• Membrane Interface Probe (MIP)
• MIP combined with HPT (MiHpt)

Dakota also combines the LIF and hydraulic profiling technologies into integrated tools, enabling users to collect high resolution hydrostratigraphic profile data simultaneously with UVOST, TarGOST and DyeLIF data. Our advanced data analysis services are available for all LIF projects, and our 2D and 3D data visualization services support our clients’ development of conceptual site models.

In addition to full service HRSC capabilities, Dakota also provides direct push soil and ground water sampling and hollow-stem auger services using all-terrain and truck-mounted equipment, and is a licensed monitoring well installation contractor in Indiana, Minnesota, Missouri, Montana, Pennsylvania, North Dakota, South Dakota, and West Virginia.

Geoprobe Systems® is not a direct image service company but specializes in the manufacturing, development, operation and training of the following direct sensing equipment: EC, HPT, MIP, LL MIP, OIP-UV, OIP-G, GWP1.75, HPT-GWS and CPT.  Our postlog analysis software - DI Viewer will help you visualize your data and offers many features including elevation changes and importing user data sets like lab analytical to view along side your MIP or OIP data. We also offer a full line of drilling machines and tools to accompany your direct sensing needs whether for confirmation sampling, injection remediation or monitoring well installation we have the tools and equipment you need.

Innovative Brownfield Management (IBM Tech) personnel have been providing clients with direct imaging services since 2001. We own three MIP setups that include one ATV mounted GC to reach locations that would otherwise be unreachable by standard motor vehicles. The other two units are mounted in our direct imaging dedicated van. This provides us with a backup unit for dealing with heavily contaminated sites. If fouled by excessive contamination, one GC can be on continuous purge while work continues with the other unit. In order to keep projects moving as smoothly as possible, IBM Tech is prepared for quick tooling changes, repairs, and maintenance. The dedicated van is equipped with a double purge station in case saturation occurs as a result of excessive contamination, and we carry extra tooling strings (assembled strings of probes, rods and trunklines) ready for rapid changing of probes if necessary. All chemical standards are laboratory prepared by a third-party to control the quality of Standard Tests made before and after each boring. We are prepared for audio-video conferencing and rapid data transmission from the field to the client in the office during and at the termination of each boring. IBM Tech is equipped to perform MIP and MiHPT work at a variety of sites such as brownfields, Superfund, industrial, and military facilities. IBM Tech offers additional services to our clients such as GPS location of borings using sub-decimeter correction services, 3D and statistical analysis of data using Rockware® and Voxler® software, and GPR clearing of boring locations prior to installation.

Professional Technical Support Services, Inc. (Pro-Tech) has offered Direct Image services for nearly 20 years. We own the equipment necessary to execute and support Soil EC, HPT, MIP and CPT projects throughout the gulf states’ region. While most projects utilize single technologies, numerous ones integrate multiple technologies. Our Direct Image services compliment ¾” Slim Gamma Logging services within Geoprobe® rods and small diameter wells. We also own a variety of supporting equipment which allows us to deploy the technologies from various platforms in less than favorable ground & weather conditions.
