Geophysical Services

Geophysical methods can be applied to a wide range of situations requiring information about subsurface conditions. Producing correct representations of geologic features and structures using geophysical methods will greatly aid in site characterization, fate and transport modeling, and optimizing the location of monitoring and remedial wells. Utilizing the most appropriate geophysical method in an efficient manner will provide useful information that can reduce project costs by decreasing the need for intrusive characterization using boreholes. Locating man-made subsurface features is of prime importance for planning and safety purposes when excavations are necessary.

Water Conservation

A water conservation plan is a strategy for reducing the volume of water withdrawn from a water supply source, reducing the loss of waste water, maintaining or improving the efficiency in the use of water, increasing the recycling and reuse of water and preventing the pollution of water. The emphasis and basic goal of a water conservation plan is to achieve lasting, long-term improvements in water use efficiency.

A water conservation plan will typically include:

  • Description of the water supply and use
  • Conservation goals, basis for the goals and schedules for achieving the goals
  • Metering devices to measure and account for the amount of water diverted from the supply source
  • Program of metering, meter testing and repair, and meter replacement
  • Measures to determine and control unaccounted for uses
  • Program of continuing public education and information
  • Means of implementation and enforcement

Drought Contingency

A drought contingency plan is a strategy for temporary supply management and demand management responses to temporary and potentially recurring water supply shortages and other supply emergencies. The philosophy of drought contingency planning is that short-term water shortages and other water supply emergency implementation procedures are defined to avoid, minimize, or mitigate the risks and impacts of drought or other water supply emergencies.

A drought contingency plan will typically include:

  • Public involvement
  • Specific criteria (trigger conditions) for the initiation of drought response stages
  • Specific water supply and/or water demand management measures for each stage of the plan
  • Public notification procedures
  • Procedures for granting variance
  • Procedures for enforcement of any mandatory water use restrictions
