Groundwater testing well installers often skip good design practices in favor of a one-size-fits-all approach. For example, a filter pack design is required by ASTM D5092, however, installers often avoid the costly and time-consuming practices of soil sampling, sieve analysis, and referencing industry standards.
This becomes particularly true in situations where two mobilizations are needed to characterize the site and to install the well. The cost savings is a false economy when measured against a well design that risks:
- Turbid and improperly filtered samples
- Pump damage
- Reduced yield and the loss of a filter pack
The WDS software developed by Navy scientists allows a user to specify candidate depth ranges and then, select the appropriate well design parameters for depths of interest. Cone penetrometer types of sensors are used to yield data that the WDS software can translate for selection of appropriate filter pack and well screen slot size specifications at the proposed screen depth ranges. WDS employs a conversion matrix based on synthetic grain-size distribution curves corresponding to the probe sensor descriptors. Instead of a probe snapshot, WDS software gives a full profile for decision making.
- Cost-effective solution that supports good well installation practices
- Eliminates the need to collect soil samples or to deploy two mobilizations
- Saves time and money to meet the ASTM standard
- Yields specifications in real-time
- Customizes multi-level wells and drilled wells with depth-specific intervals
