GENERAL

Thiele Geotech offers a complete package of environmental engineering services.

TG’s environmental staff brings years of experience to every environmental project that it completes. It is this experience that allows TG to understand the often complicated balance between managing environmental risk and controlling expenditures. Because our professional staff has completed such a varied and numerous array of environmental projects, TG can quickly identify a clients needs, and complete the project quickly and in a cost-effective manner. Service to our clients is our primary concern.

PHASE I ENVIRONMENTAL SITE ASSESSMENTS

TG and its environmental staff have conducted hundreds of environmental assessments throughout the Midwestern United States. These projects have included office, retail, manufacturing and industrial facilities and were performed for various types of clients. Our Phase I Environmental Site Assessments are prepared in accordance with the American Society of Testing Materials (ASTM) Standard E 1527 fulfilling inquiry requirements of the innocent landowner defense established under CERCLA. This defense as established under the Superfund Amendment and Reauthorization Act (SARA) in 1986, encouraged many to conduct environmental investigations prior to taking ownership of real estate. To fulfill inquiry requirements as stipulated under SARA, several steps must be completed and include, but not necessarily limited to, the following:

Records Review - The records review attempts to help identify recognized environmental conditions by examining available topographic or geologic maps, aerial photographs, public records that are properly filed regarding permits, spills, underground storage tanks (UST’s), landfills, and hazardous substance/waste sites, and other government records.

Site Reconnaissance - The site reconnaissance is a visual investigation of the property and surrounding area. This walkover of the property includes the entire site, accessible areas in the interiors of the buildings and adjacent public thoroughfares. Special attention is given with regards to evidence of below ground tanks, distressed vegetation, signs or evidence of hazardous substances/wastes or petroleum products, waste or rubble, or any evidence of illegal disposal/storage practices.

Interviews - If possible and if authorized by the client, interviews with the owners/occupants of the property are conducted in an attempt to obtain information about the past uses of the site. Also appropriate government officials may be interviewed in an attempt to identify recognized environmental conditions that may be associated with the site or surrounding area.
Written Report - A written report documenting the analysis, opinions, and conclusions of the investigation is prepared which characterizes the recognized environmental condition of the property or potential environmental concerns of surrounding properties.

PHASE II ENVIRONMENTAL SITE ASSESSMENTS

Information accumulated during the completion of a Phase I Environmental Site Assessment often times indicates that the potential for chemical contamination from either on-site or nearby activities is high. Generally, a Phase II Environmental Site Assessment is conducted to qualitatively and quantitatively identify if chemical contamination is present, and if so, at what concentrations and areal extent.

Soil and/or ground water samples are collected at areas on-site that have the greatest potential of being contaminated and then submitted to the laboratory for analysis. This intrusive phase of the project is enhanced because TG maintains its own drilling fleet fully outfitted for environmental drilling. Because we do maintain our own drilling fleet, it allows us to prioritize and dictate the drilling schedule to meet various time constraints.

After receipt of the laboratory results, a comprehensive report is generated that outlines a summary of the work performed, the results of the soil and ground water testing, the extent of contamination (if any), potential regulatory response, and the environmental risk associated with the identified contamination. Remediation options are prepared and discussed at length with regards to long-term liability, health and safety risks, and projected costs to afford the client to make an informed decision regarding property acquisition or remedial actions.

UNDERGROUND STORAGE TANK PROJECTS

TG has extensive experience in the assessment and remediation of releases from underground storage tanks (UST’s). TG has completed UST projects throughout the Midwestern United States and has intimate knowledge of the various State and Federal programs regulating the storage of hazardous materials in below grade tanks. In addition to the technical expertise that TG offers, TG provides assistance to the owner/operator in cost recovery issues. Many States offer various forms of reimbursement funds to provide partial financial offset for costs incurred during assessment and/or remediation of spills occurring from UST’s. Detailed cost accounting and investigative techniques that minimize expenditures help to assure that the owner operator will receive maximum benefits under these reimbursement plans.

EMERGENCY RESPONSE PROJECTS

TG personnel have experience with providing emergency response services on projects located as far away as Portland, Oregon. These emergency response services were regarding sudden releases to the environment from accidents involving trucking companies. These services were provided to various insurance companies to insure quick and efficient cleanup of the affected media, whether it be soil, surface water or ground water. TG has experienced environmental staff that are able to make the tough decisions in the field that allow for progress in the remediation process in the critical time immediately following a release.

ENVIRONMENTAL CONTRACT DRILLING SERVICES

TG's practice includes professional contract drilling services. Although our company is relatively new, its principals have over twenty years of experience managing professional contract drilling services. TG currently has a full-line environmental drilling program including a fully outfitted drilling fleet, environmental support trailer (including Hotsy® steam cleaner and portable water tank) and the necessary personnel protection and decontamination equipment. TG’s drill crews are 40-Hour OSHA trained and possess current 8-hour refreshers and medical surveillance exams. TG’s areas of expertise include:

Foundation Investigations
Monitoring Well Installation/Abandonment
Materials Exploration and Evaluation
Ground Water Contamination Assessment
Soil Contamination Assessment
Instrument Installation
Stratigraphy Investigations
Grouting and Pressure Grouting

TG is licensed to perform well contracting services in many states throughout the Midwest. Current licenses/certifications include:

Well Drilling Contractor - State of Nebraska (No. 89019)
Water Well Monitoring Supervisor - State of Nebraska (No. 89026)
Certified Water Well Contractor - State of Iowa (No. 40076)
Certified Water Well Contractor - State of Missouri (No. 003032)
Certified Well Driller - State of South Dakota (No. 594)
Licensed Water Well Contractor - State of Kansas (No. 616)
Certified Monitoring Well Contractor - State of North Dakota (No. 441)
Certified Monitoring Well Contractor - State of Oklahoma (No. DPC-519/OP-1065)

Because the principals at TG have extensive experience managing drilling services on their own projects, we understand the importance of completing the drilling phase of a project on-time and in a cost-effective manner. TG strives to complete our drilling services in the most professional manner possible, to satisfy both your project needs and your customers expectations.
