Applied Technology, Inc.’s hydrogeologists have performed site assessments of many types for clients throughout the United States.

Our Site Assessment Services Include:

› Phase 1 Property Assessments

› Remedial and Site Assessments

› Karst Assessments

Our assessments are designed to identify potential environmental liabilities and provide the data necessary to correctly solve the problem. If site data does not truly represent the conditions of the site, then important interpretations involving contaminant migration, remediation effectiveness, and even closure, will be incorrect.

All of our assessment projects are designed and managed by experienced Applied Technology, Inc. staff with professional geologists or professional engineering licenses. Applied Technology, Inc. also takes a team approach to larger assessment projects by involving chemists, geologists, engineers and biologists to utilize their individual expertise in design, implementation and interpretation of the assessment.

Phase 1 Property Assessments

Phase 1 assessments are designed to identify potential environmental liabilities. Applied Technology, Inc. conducts our Phase 1 assessments according to what is indicated in ASTM E1527, Standard Practice for Environmental Site Assessment: Phase 1 Environmental Site Assessment Process. With our licensed asbestos and lead inspectors, our Phase 1 assessments can be expanded to identify asbestos or lead containing building materials to enhance your knowledge about the property.

Remedial and Site Assessments

Our staff has conducted more than 200 site characterization and assessment projects, ranging from Superfund remedial investigations to UST closure investigations. These assessments involved collecting thousands of soil and ground water samples for analysis. Both sample collection and lab analysis are conducted according to Applied Technology, Inc. Quality Assurance Project Plan documents prepared for each project. Applied Technology, Inc. has also prepared and had approved more than 50 sampling and analysis plans with five state agencies.

Karst Assessments

Because of education and past project opportunities, our staff has considerable experience with the unique hydrogeology of karst (cave and spring containing) landscapes. The unique characteristics of these areas necessitate someone with experience to conduct site investigation and remediation projects. Assessment or remediation projects in karst areas should at the very least, be reviewed by a hydrogeologist familiar with the conditions. Karst aquifers do not behave like the more common laminar aquifers; contaminants in a karst aquifer often travel in slugs and can travel very quickly, compared to normal ground water conditions. It is very important to conduct a basin assessment for municipalities that get their water supply from karst springs in order to identify potential hazards to the water supply and develop a protection plan accordingly.

Project Experience:

Applied Technology, Inc. directed subsurface investigations and product recovery operations at a 10,000-gallon mineral spirits release into a carbonate aquifer beneath a large aluminum product manufacturing plant. The assessment and remediation operations were hampered by extremely thick concrete and numerous utility trenches. Previous investigations by another consultant did not consider the utility trenches as possible conduits for contaminant migration, and missed identifying a large portion of contaminated material. If a large rain event had occurred before the contaminated materials were removed, the contamination would have traveled to the spring used as the city’s water supply.

Contracted to perform remedial investigation at a Federal Superfund site. The investigation consisted of more than 20 surface sampling and 30 soil boring locations in a former industrial setting filled with construction debris. The assessment resulted in identifying a smaller amount of buried waste material than was previously estimated and lower disposal costs for our client. Our sampling plan and quality assurance procedures passed the scrutiny of EPA oversight personnel and remediation began ahead of schedule.

Applied Technology, Inc. was hired to write a RCRA Closure Work Plan and Groundwater Sampling and Analysis Plan for a waste site under a State Consent Decree. The assessment of the property involved delineating the extent of arsenic powder and liquid pesticide waste materials that had migrated from the containment area. The assessment took place in several stages to limit expenditures. The results of the assessment determined the boundaries of the surface, subsurface and ground water contamination of each waste material beneath the facility.

Conducted a Phase 1 Site Assessment of an abandoned manufacturing facility in a large, active industrial park. Previous site assessments in recent years failed to identify the significance of metals groundwater contamination previously identified on the property as being above Federal MCL concentrations. Previous Phase 1 Assessments also failed to identify a possible source for the elevated metals in the ground water. A neighboring facility had a plating sludge RCRA Corrective Action project in the early 1980s less than 300 feet from the property boundary.

Applied Technology, Inc. designed and managed three-dye trace studies designed to characterize the laminar flow shale and diffuse-flow carbonate aquifers beneath three different cyanide plating operations at a large wire manufacturer to identify the source of possible ground water contamination. Once the aquifer was identified, we designed and implemented a RCRA post-closure monitoring program for the site.

Conducted a Phase 1 Site Assessment of an abandoned manufacturing facility. Previous site investigations failed to identify the significance of metals groundwater contamination, and previous Phase 1 Assessments failed to identify RCRA Corrective Action involving plating sludge at a neighboring facility. Groundwater monitoring by ATI concluded the metals contamination was emanating from the location of the former HWMU.
