Underground Storage Tank Locating
Underground storage tanks are a great concern and environmental liability for property owners, potential buyers, and lending institutions. These concerns stem from the fact that underground storage tanks have not only environmental implications, but legal and economic impacts.
Often buried oil storage tanks were abandoned long ago and even the current owner does not know of their existence. Because environmental regulations consider the property owner liable for these underground tanks, it is important to discover underground tanks before you take ownership of a property. Geophysical methods not only locate hidden tanks, but delineate them so that they are not damaged during test drilling causing an even bigger problem.
Underground Utility Locating
Underground pipes and utilities pose significant problems to any construction project or subsurface investigation program. Modification of design specifications can be costly in both time and money. Everyday more and more utilities are being installed and buried with no proper documentation. Geophysical methods can be used to locate underground utilities to control risk and avoid potential conflicts that increase project costs.
Site activities that require the location and site mapping of underground utilities are soil boring, test pitting, excavation, demolition, reconstruction, the removal of underground tanks, and servicing old utilities. These activities often involve the excavation of large areas, increasing the odds that you will encounter underground utilities. Finding utilities in this way can be dangerous and expensive.
Landfill Delineation
Older landfills are being remediated for future construction projects. The nature and extent of the fill must be determined for a successful remedial design and to determine construction costs. Geophysical methods can be applied to locate the nature and extent of the fill and enhance traditional drilling techniques. This combination of techniques provides better information for acquisition, planning and site development by reducing your uncertainty and avoiding surprises. In addition to landfill delineation and characterization, geophysical techniques are applied to provide information about Leachate plumes and located failed and leaking liners. Geophysics has proven effective in countless landfill locations and remedial investigations.
Septic System and Tank Locating
Finding areas of higher soil thickness in areas of thin soil cover prior to development can be accomplished with several geophysical methods. This can save both time and money by providing guidance prior to test pit investigations.Existing septic systems and tanks can be located and mapped prior to repair or replacement. In areas with high population density, groundwater pollution from septic tanks often exceeds acceptable limits and conversion to public sewer is required. Therefore the use of geophysical methods to locate on-lot systems for proper abandonment has grown significantly in recent years.
Locating Voids, Locating Tunnels
Caves, voids, sinkholes, tunnels and abandoned mines can lead to dangerous situations for people and property. Subsurface voids can cover a full spectrum of depth and severity, from collapsing sidewalks to surface subsidence from old mine tunnels.Locating voids and tunnels will minimize potential liability, reduce possible work delays, and dangerous future problems. Sinkholes and void spaces have caused damage to highways, roads, and buildings. Before void spaces cause damage they can be detected with several geophysics methods.
