BQCIS

Comprehensive Assessment of Polluted and Impacted Soils

Soil contamination poses significant environmental and human health risks when industrial, agricultural, or mining activities release hazardous substances into the ground. BQCIS provides accredited laboratory testing for identifying toxic elements, hydrocarbons, and organic pollutants to evaluate compliance with EPA, ISO 11047, and EN 1483 standards.

Our multidisciplinary teams support site investigation, baseline characterization, and remediation design. Using advanced analytical techniques like ICP-MS, GC-MS, and HPLC, we quantify heavy metals (Pb, Cd, Hg, As), total petroleum hydrocarbons (TPH), pesticides, PCBs, and phenols across soil matrices.

Results from BQCIS enable regulatory reporting, risk assessment, and sustainable remediation planning for industrial zones, fuel depots, landfills, and agricultural catchments.

Key Activities in Soil Contamination Analysis

Sampling & Chain of Custody

Representative sample collection using EPA/ISO protocols with full documentation and custody traceability.

Heavy Metal Determination

Quantitative analysis of Pb, Cd, Hg, As, Cr, Ni, and Zn using ICP-OES or ICP-MS following ISO 11047 and EPA 3050B.

Hydrocarbon & Oil Residue Testing

Extraction and quantification of total petroleum hydrocarbons (TPH), PAHs, and VOCs by GC-MS or GC-FID.

Pesticide & Herbicide Screening

Targeted screening for organochlorine, organophosphate, and carbamate residues per EPA 8081/8082.

Organic Compound Identification

Detection of PCBs, phenols, and dioxins using HPLC and high-resolution GC/MS.

pH, Conductivity & Moisture Testing

Physical soil characterization for acidity, electrical conductivity, and moisture content evaluation.

Regulatory Compliance Evaluation

Comparison of results against EPA, EU REACH, and ISO 14001 environmental thresholds.

Data Reporting & Remediation Support

Comprehensive interpretive reports including contamination maps, exceedance tables, and corrective recommendations.

Asbestos & Fiber Analysis

Identification and quantification of asbestos fibers in soil and building materials using polarized light microscopy (PLM).

Success Story

Soil Remediation Validation for Fuel Depot Redevelopment

The Challenge:

A decommissioned fuel depot exhibited hydrocarbon and lead contamination exceeding EPA standards across multiple sampling zones.

Our Solution:

BQCIS performed site-wide sampling, GC-MS and ICP-MS analysis, and delivered geospatial contamination mapping to guide excavation and remediation plans.

The Result:

Post-remediation testing confirmed pollutant reduction by 96%, clearing the site for industrial redevelopment and ISO 14001 certification alignment.
