We pulled up to a former dry-cleaning site off Battlefield Boulevard where decades of solvent releases had left a plume of PCE migrating under the parking lot. The owner wanted a fast sale, so we set up a phased contaminated soil remediation plan within the first week. First came a detailed site assessment with soil gas probes and groundwater monitoring wells, using PID screening and lab analysis for VOCs. After that, we excavated the hot spot down to 14 feet and backfilled with clean structural fill. The whole sequence took less than three weeks because we coordinated with the Chesapeake DEQ office ahead of time. That kind of pace comes from knowing the local geology and the regulatory path. Before any remediation design, we always recommend a study of soil mechanics to map contamination boundaries and a permeability test in the field to predict how fluids move through the clay-sand layers typical of this Tidewater region.

Approach and scope
Site-specific factors
Chesapeake grew fast through the 1980s and 90s, converting farmland and marsh into strip malls and subdivisions. That same land held undocumented storage tanks, old dumping pits, and pesticide sheds. When you dig for a new foundation, you can hit a plume that nobody knew about. The risk is real: a hidden hotspot can halt construction for months while agencies decide on cleanup levels. We have walked into projects where the general contractor already broke slab, only to find diesel odors at 6 feet. Contaminated soil remediation in those cases requires emergency response, soil segregation, and expedited lab turnaround to keep the schedule alive. Our team coordinates directly with the Chesapeake Environmental Health Division to get approvals moving fast.

Site Assessment & Phase II ESAs
We drill soil borings, install monitoring wells, and collect discrete samples for laboratory analysis of VOCs, SVOCs, metals, and petroleum hydrocarbons. Our reports follow ASTM E1903 Phase II standards and include risk-based recommendations.
Excavation & Off-Site Disposal
For source zones above the water table, we dig, segregate, and haul contaminated soil to permitted Virginia facilities. We manage air monitoring, dust control, and disposal manifests so the client stays compliant with DEQ.
In-Situ Bioremediation & Chemical Oxidation
We inject oxygen-releasing compounds or persulfate-based oxidants into the saturated zone to degrade petroleum and chlorinated solvents. This approach avoids excavation and works well beneath operational parking lots or buildings.
Post-Remediation Verification & Closure
After treatment, we collect confirmation samples from sidewalls, base, and groundwater monitoring wells. We compare results to Tier I RSLs and prepare a closure report that the Virginia DEQ accepts for case closure.

FAQ
What contaminants are most common in Chesapeake soils?
Petroleum hydrocarbons from old underground storage tanks and chlorinated solvents from former dry cleaners are the two most frequent contaminants we encounter. Heavy metals like lead and arsenic show up near historical industrial fill and older residential areas along the Southern Branch of the Elizabeth River.
How much does contaminated soil remediation cost in Chesapeake?
Typical project costs range from US$2,830 to US$13,100, depending on contaminant type, volume of soil treated, depth to groundwater, and whether you need excavation or in-situ treatment. A small petroleum hotspot can fall at the lower end, while a chlorinated solvent plume with multi-round injections climbs toward the upper bound.
How long does a typical remediation project take?
Source-zone excavation with verification sampling usually finishes in two to six weeks. In-situ bioremediation or chemical oxidation may require three to six months of monitoring because the treatment reactions need time to reduce concentrations below Tier I screening levels.
Do I need a Virginia DEQ permit for remediation?
Yes, most remediation activities in Chesapeake fall under the Virginia DEQ Voluntary Remediation Program or a corrective action plan for UST releases. We submit the work plan, manage air monitoring if excavation exceeds certain volumes, and coordinate with the Chesapeake Environmental Health Division to keep the project on track.
