Visual Survey
A documented walkover noting surface indications of tanks, fill pipes, vents, heating oil lines, dye markers, and signs of staining or fill activity.
An Oil Tank Sweep Inspection reduces transaction risk by revealing hidden storage tanks or contamination that can affect property value, financing, insurance, and regulatory compliance. Early detection limits cleanup costs, clarifies seller disclosures, and helps lenders and buyers assess environmental liability before closing.
Each party uses the inspection results differently: buyers for risk assessment, lenders for underwriting, and consultants for remediation planning.
A documented walkover noting surface indications of tanks, fill pipes, vents, heating oil lines, dye markers, and signs of staining or fill activity.
Electromagnetic (EM) or metal detector scanning to identify buried metallic tank components, piping, and associated utilities; used to target further investigation.
Ground-penetrating radar (GPR) imaging to detect non-metallic or deeper anomalies and to confirm suspected tank locations identified by EM.
Targeted soil and/or groundwater sampling at locations of concern, submitted to a certified laboratory for petroleum hydrocarbon analysis.
Geotagged photos and maps showing surveyed areas, probe locations, anomalies, and any accessible tank components to support the written findings.
A concise report summarizing methods, results, GPS coordinates, lab attachments, risk assessment, and recommended next steps for remediation or monitoring.
