Well Development & Sampling
Professional monitoring well development and groundwater sampling — low-flow micropurge sampling, quarterly monitoring programs, and post-remediation performance assessment with complete regulatory documentation.
Applications
- New monitoring well development after installation
- Periodic groundwater sampling for long-term monitoring
- Low-flow sampling for VOC and SVOC analysis
- Purge-and-bail sampling for regulatory compliance programs
- Post-remediation performance monitoring sampling
- Quarterly and annual groundwater monitoring programs
- Remediation system performance groundwater sampling
- Phase II ESA groundwater sampling programs
Key Advantages
- Low-flow micropurge sampling minimizes waste and sample disturbance
- Field parameters measured in real-time (pH, ORP, DO, conductivity)
- Portable peristaltic and bladder pump systems available
- Full chain-of-custody documentation for regulatory submittals
- Experience with all major state and federal sampling protocols
- Sampling integrated with drilling for one-mobilization efficiency
About Well Development & Sampling
Proper well development is critical to obtaining representative groundwater samples. After installation, IET develops monitoring wells using surge-and-bail, pumping, or airlifting methods to remove drill cuttings and fine sediment from the filter pack — ensuring the well yields clear, representative groundwater samples. Field parameters including pH, ORP, dissolved oxygen, temperature, and specific conductance are measured during purging to confirm stabilization prior to sample collection.
IET's groundwater sampling programs follow low-flow micropurge protocols where required, minimizing purge volumes and sample disturbance for accurate VOC analysis. All samples are collected with proper chain-of-custody documentation and delivered to certified analytical laboratories. IET supports quarterly, semi-annual, and annual monitoring programs as part of long-term site monitoring requirements and post-remediation performance assessment.
