ENV-TLG-28
Soil Contamination & Field Screening
Tailings Paste pH, Conductivity & Leachate Toxicity Characterization
Detailed characterization of mineral tailings slurry, filter cake, and dry stack residues to predict leachate toxicity, metal mobility, and long-term environmental behavior.
Detection Limits
pH 1.0 – 14.0 | Metals in leachate down to ppb levels
Turnaround (TAT)
Standard: 5-7 Working Days
Sample Requirement
2.0 kg representative wet or dry tailings
