ENGINEERING GEOLOGY

ATS International helps you identify and understand geologic problems related to the planning and implementation of engineering projects.

By understanding the local geology of a slope problem, mapping the discontinuities, and performing stereonet analyses, the hazards of mass movement can be characterized and mitigated.

HYDROGEOLOGY

ATS International provides expert services in a broad range of hydrologic applications.
By combining a thorough knowledge of geologic systems with geophysical and computer modeling techniques, ATS can help locate water supplies, assess and remediate soil and groundwater pollutants, and protect water resources.

A rock


excavating a foundation

BEDROCK MAPPING

A university in North Carolina planned a major construction project involving extensive excavation. Borings at the site indicated a highly irregular bedrock surface, resulting in high contractor bids to cover the contingency of rock removal. ATS used electrical resistivity imaging to create cross-sections of the soil-bedrock interface. This allowed accurate volumetric calculations of soil and bedrock to be removed and saved the university close to $100,000, many times the cost of the services.


drilling a water well

HIGH YIELD WATER SOURCE

A land developer was considering the purchase of 130 acres of land for residential development. The purchase was contingent on obtaining a community water source that could provide a minimum of 58,000 gallons per day (40 gpm) to the proposed 70 homes. ATS conducted aerial photographic analysis, geologic analysis and electrical resistivity imaging to identify likely drilling locations for a high production well.

Drilling at the first recommended location resulted in a well yielding 130,000 gallons per day (90gpm) and the second recommended location yielded 230,000 gallons per day (160 gpm). Available statistics suggest that less than five percent of the wells drilled in the Blue Ridge Province produce at this rate. A randomly drilled well 500 feet away produced only 2,900 gallons per day (2gpm).


mapping buried waste

MAPPING BURIED WASTE

The location of a proposed building site was underlain by known buried waste from industrial activities from the 1970’s. The distribution and thickness of the buried waste had been partially determined through test pit excavations, but the client couldn’t evaluate the entire site. ATS utilized electromagnetic induction to map the lateral extent of the buried materials and ground penetrating radar and electrical resistivity to provide vertical imaging data . The resistivity data also revealed a likely leachate plume extending beyond the physical limits of the waste materials that may have been missed had the imaging not been done.


well targeting

WELL TARGETING

A land developer had partially completed a 100-acre residential development. Eight dry wells had been drilled, resulting in the loss of more than $25,000 in drilling costs. ATS conducted aerial photographic analysis, geologic analysis and electrical resistivity imaging. ATS recommended six drilling locations, all of which were drilled. While the six wells comprised only 14 percent of the community’s 42 wells, they represented over 33 percent of the total yield. The 36 wells drilled before ATS’s involvement produced only 11 gallons per day per foot of well. The ATS wells provided 42 gallons per day per foot of well, almost 4 times the productivity of the randomly drilled wells.

What Others are SayingTestimonials

“

They are responsive and call back quickly. I can pick up the phone and Ted will answer.

“

We were able to show our clients that if we spend a little more money now it can save us a lot of money during the construction phase.

“

I was able to combine what ATS did with our bore holes to create maps that gave the client a great picture of the site. And, using the ATS work I was able to go back to confirm some rough spots to within a foot or two. There was no guess work.

“

We use them exclusively for our geophysical needs.

“

Very professional.

“

His resistivity work is excellent, and we’ve gone back and done some bore holes that proved his data. So, we’ve been satisfied.

“

Our projects with ATS have been a huge success.

“

The work I’ve gotten has been outstanding and I’ve gotten great feedback from our clients.

What I got was well above what I thought I’d get and I’m usually a very hard guy to please.
