GEOLOGIC QUESTIONS ABOUT:
LOST UTILITIES
Where are the pipes? Where are the sewer lines? Where are the high-voltage underground power lines? Where are the natural gas lines? Where are the PVC conduits? Where can I safely drill? How do I locate utilities?
Geophysical Solution:
GOOD METHOD: Magnetics (M-11)
BETTER METHOD: Electromagnetics for Metal Detection (M-5)
BEST METHOD: Utility Locator (M-13)
Honorable Mention: Ground Penetrating Radar (for PVC) (M12)
