Reliable, Cost-Effective Groundwater
Monitoring & Characterization

The Westbay System is a multilevel groundwater monitoring technology that allows testing of hydraulic conductivity, monitoring of fluid pressure, and collection of fluid samples from multiple zones within a single borehole.

The sophisticated features of the Westbay System represent a significant advancement in groundwater monitoring capability. You’ll increase the quantity and quality of your data within a reasonable budget, meaning you can afford the information you need to improve long-term water management decisions.

  • Get detailed three-dimensional data—leading to an improved understanding of hydrogeological conditions and contaminant transport.
  • Minimize storage volume and prevent flow along the borehole.
  • Reduce drilling and installation costs.
  • Drill fewer holes and reduce site disturbance.
  • Avoid cross-contamination through discrete sampling.


Multilevel monitoring, sampling without repeated purging, removable sensors, verifiable good integrity.

  • Any number of monitoring zones in a single well
  • Additional data at a small incremental cost
  • Sealed monitoring zones
  • Option for automated monitoring of multiple depths
  • Samples obtained at formation pressure
  • Removable and upgradeable probes
  • Option to monitor chemical parameters
  • Improved security
  • Defensible field QA/QC procedures
