TranslateWell Abandonment
Regulatory-compliant monitoring well abandonment and decommissioning — proper grouting, casing removal, and documentation for site closures, redevelopment projects, and remediation program completion.
Applications
- Monitoring well decommissioning at site closure
- Plugging and abandonment of no-longer-needed wells
- Regulatory-compliant well abandonment per state standards
- Abandoned water supply well decommissioning

- Remediation system well decommissioning
- Pre-redevelopment site well closure programs
Key Advantages
- Full compliance with state and local well abandonment regulations
- Proper grouting with neat cement or bentonite per spec
- Casing removal or in-place abandonment options
- Detailed abandonment records and regulatory submittals
- Efficient mobilization for multi-well abandonment programs
- Licensed and experienced well abandonment crews
About Well Abandonment
When monitoring wells, injection wells, or piezometers are no longer needed, proper abandonment is required by state and local regulations to prevent cross-contamination between aquifer zones and to eliminate potential pathways for surface contamination to reach groundwater. IET performs well abandonment services for environmental site closures, regulatory case closures, and pre-redevelopment programs.
IET's abandonment procedures include casing removal (where required), tremie-pipe grouting with neat cement or bentonite-cement mixtures, surface restoration, and preparation of abandonment records for regulatory submittal. Our crews are experienced with multi-well abandonment programs at sites with large monitoring networks, efficiently completing closure work to support site redevelopment timelines.

Well Abandonment & Decommissioning — Frequently Asked Questions
Common questions about regulatory-compliant monitoring well abandonment, grouting, and site closure documentation.
What is environmental well abandonment and why is it required?
Well abandonment (decommissioning) permanently seals monitoring, injection, or water supply wells at site closure or when they are no longer needed. Proper abandonment prevents cross-contamination between aquifers and is required by state regulations — improperly abandoned wells can create pathways for contaminant migration.
How is a monitoring well properly abandoned?
IET removes the casing (or abandons it in place per specification), over-drills the borehole, and grouts with neat cement or bentonite in staged lifts to prevent channeling. Surface completion is finished to state requirements, with full abandonment records provided for regulatory submittal.
What grout materials does IET use for well plugging?
IET uses neat cement (Portland cement and water), cement-bentonite, and sodium bentonite chips or grout, selected per state well abandonment standards and site geology to ensure a low-permeability seal that prevents fluid migration.
Can IET handle multi-well abandonment programs?
Yes. IET mobilizes crews and rigs for multi-well decommissioning at remediated sites, former industrial facilities, and pre-redevelopment properties, completing batch abandonment efficiently with documented regulatory records for every well.
Are well abandonment records provided for regulators?
Yes. IET provides boring logs, abandonment diagrams, grout volume records, and state-specific submittal forms documenting regulatory-compliant well closure for your project file and agency review.
