Water Level/Pressure

Water level or pressure head readings are taken for a number of reasons. In aquifer characterization, this type of data will help the user determine important hydrologic parameters of an aquifer, including hydraulic conductivity, transmissivity, permeability, storage coefficient, dispersivity, and porosity. Some or all of these parameters are important in the design of wells and well fields for various purposes.

In the design of a remediation system, the proper placement of wells for monitoring or extraction is of paramount importance if the system is to function effectively. Accurate data from slug and pump testing is one of the primary tools employed for aquifer characterization in the design process.

Step testing and constant-rate pump testing yield significant data in determining proper pumping rates. Improper rates can lead to aquifer depletion, salt water intrusion, and several other problems. Accurate data in designing the system and monitoring the system is essential for long-term success of the well and the proper maintenance of the aquifer.

The collection and use of water level measurements in the mining and coal bed methane industries are essential for the success of the mines and wells. Data derived from pilot testing of water wells constructed for coal bed methane extraction provide necessary information on bottom-hole pressure and appropriate pumping rates to accomplish the de-watering necessary to release the methane gas. Monitoring of water levels assures efficient production.

Water level measurements of surface water by pressure measurements yield significant data about the overall health of the hydrologic cycle. This information is also useful to government, agriculture, and industry as well as the scientific community when planning water use and when adjudicating water rights issues.
