About Monitoring Well Installation
Monitoring wells are the foundation of any groundwater investigation or long-term environmental monitoring program. IET installs 1-inch, 2-inch, and 4-inch diameter PVC monitoring wells using hollow-stem auger, direct push, and rotary drilling methods — selecting the appropriate technique based on formation conditions, required depth, and well purpose.
Each well is constructed to meet state and federal regulatory requirements, with proper screen interval placement, filter pack, bentonite seal, and surface completion. IET's crews complete full boring logs, well construction diagrams, and development records for every installation. With 5,000+ drilling projects since 1998, IET delivers monitoring well networks that provide accurate, defensible groundwater data.

Monitoring Well Installation — Frequently Asked Questions
Answers to common questions about IET's monitoring well installation services for groundwater sampling, Phase II ESAs, and remediation performance monitoring.
What sizes of monitoring wells does IET install?
IET installs 1-inch, 2-inch, and 4-inch diameter monitoring wells in PVC or stainless steel, with screen intervals and filter pack gradations sized to the target aquifer zone and the contaminant — including LNAPL and DNAPL — being monitored.
What drilling methods are used for monitoring well installation?
IET uses hollow-stem auger for shallow to moderate depths and direct push for rapid, small-diameter wells, selecting the method based on depth, geology, well diameter, and site access. Proper bentonite seals and cement grout annular seals meet regulatory construction requirements.
What is well development and why does it matter?
Well development — surging, bailing, and pumping — removes fine sediment and drilling fluids after installation so the well yields representative groundwater. IET develops each well to achieve turbidity and yield targets before the first sampling event.
Are these wells suitable for Phase II ESAs and long-term monitoring?
Yes. IET installs monitoring wells for Phase II Environmental Site Assessments, regulatory compliance sampling, remediation performance monitoring, and long-term groundwater monitoring networks, with construction diagrams and chain-of-custody sampling protocols.
Does IET provide monitoring well installation nationwide?
Yes. IET mobilizes drilling crews nationwide from Pennsylvania, Ohio, Texas, South Carolina, North Carolina, and Florida for monitoring well programs of any size, including injection well networks for in situ remediation systems.
