Groundwater Investigation & Monitoring Wells
Defensible data from installation through closure.

Where Groundwater Programs Go Sideways
Under-Scoped Well Networks
Baseline networks that skimp on downgradient wells miss plume geometry and force expensive re-drilling once the LSRP or NYSDEC reviewer flags data gaps.
Sampling Methodology Drift
Non-low-flow sampling produces turbid, unrepresentative data. Reviewers reject it, and you pay to sample again — sometimes after invalidating a whole year of monitoring.
Emerging Contaminants
PFAS, 1,4-dioxane, and other emerging analytes now belong in monitoring plans at sites with historic industrial or firefighting activity — but only when method selection matches state guidance.
Groundwater Services
From well installation through plume delineation, one LSRP-led team keeps groundwater data defensible from field to closure report.
Monitoring Well Installation & Development
Sites needing baseline groundwater data, LSRP-directed monitoring networks, or long-term post-closure monitoring under NJDEP or NYSDEC oversight.
Turnkey installation of shallow and deep groundwater monitoring wells with hollow-stem auger, sonic, or air-rotary methods. Includes NJDEP/NYSDEC-compliant well construction, development, survey, and permanent identification for long-term monitoring programs.
What's Included
- Well construction plan & permit filings
- Hollow-stem, sonic, or air-rotary drilling
- PVC or stainless well construction to NJDEP/NYSDEC spec
- Well development & purge documentation
- Sub-meter GPS survey & permanent marker
- Well completion report
Groundwater Sampling & Low-Flow Programs
Owners with recurring monitoring obligations under NJDEP, NYSDEC, or federal orders — including CEA/deed notice sites and post-closure programs.
Quarterly, semi-annual, or annual groundwater sampling using EPA low-flow (minimal drawdown) methodology. Includes field parameters, chain-of-custody, laboratory coordination, and data validation against NJDEP GWQS or NYSDEC Class GA standards.
What's Included
- Low-flow (EPA 542-S-02-001) sampling
- Field parameters (pH, DO, ORP, conductivity, turbidity)
- VOC, SVOC, metals, PFAS, or 1,4-dioxane analysis
- Chain-of-custody & lab coordination
- Data validation & tabulation
- Quarterly monitoring report
Plume Delineation & Aquifer Testing
Sites in remedial investigation, feasibility study, or closure planning where plume geometry drives remedial cost and schedule.
Full contaminant plume delineation with iterative drilling, multi-level sampling, and aquifer testing (slug, pump, or step-drawdown). Deliverables include hydrogeologic conceptual site model, plume maps, and remedial alternatives screening for closure planning.
What's Included
- Iterative delineation borings & wells
- Multi-level & discrete-depth sampling
- Slug, pump, or step-drawdown testing
- Hydrogeologic conceptual site model
- 3D plume visualization & maps
- Remedial alternatives screening
LSRP-Led Groundwater Programs
Every well network, sampling program, and delineation study is overseen by a Licensed Site Remediation Professional. Data validation, chain-of-custody, and reporting stay defensible when the regulator or opposing counsel asks the hard questions.
