High-Resolution Characterization and Monitoring
EDN provides hydrogeological instrumentation and field services for high-resolution characterization and monitoring — borehole geophysical logging, straddle packer testing and multi-level groundwater monitoring.
This is the plain, fast version of the homepage. The full version descends the borehole.
What we do
Three services that resolve a borehole into intervals.
Run individually or as one vertically integrated programme — the logs find the fractures, the packers test them, the multi-level system monitors them.
Borehole Geophysical Logging
Downhole logging and video survey with a sixteen-tool inventory, run by trained crews, 24/7.
Read more →02Straddle Packer Testing
Turn-key packer testing with an extensive inventory of packers, data logging instrumentation and sampling pumps.
Read more →03Multi-Level Monitoring
Discrete-interval head and water quality data from a single borehole, instead of a cluster of wells.

What the three services actually do.
Borehole Geophysical Logging
EDN conducts borehole geophysical logging services and video surveys using downhole equipment and trained personnel that continue to set the industry standard.
Read more →Straddle Packer Testing
Earth Data Northeast offers turn-key packer testing services featuring an extensive inventory of packers, data logging instrumentation and sampling pumps.
Read more →Multi-Level Monitoring
Multi-Level groundwater monitoring systems allow for the collection of hydraulic head pressure and water quality data from a single borehole instead of multiple wells of varying depths.

Forty-eight documented sites. The prime contractor named on every one.
EDN publishes its project list rather than describing it. Superfund, federal facility, landfill and public-supply work across the eastern United States and Puerto Rico — each entry with the consultancy or agency that engaged us.

Who reads your data
The people who run the tools write the report.
EDN is small on purpose. The principals are in the field and on the interpretation, which is why a log comes back with an opinion attached rather than just a trace.

Tell us about the borehole.
Depth, casing, formation, what you are chasing and when you need to be in the field. A geoscientist will come back to you — not a form response.
