characterization drilling
nounPronunciation: /ˌkɛrɪktərəˈzeɪʃən ˈdrɪlɪŋ/
Systematic drilling program conducted to gather subsurface data about contamination extent, geology, and hydrogeology at abandoned mine sites.
Full Definition
A planned investigation involving drilling boreholes at strategic locations to collect soil, rock, and groundwater samples for laboratory analysis, while also installing monitoring equipment and gathering geotechnical data. The program provides essential information about contamination distribution, geological conditions, groundwater flow patterns, and engineering properties needed for remediation design. Results inform risk assessments, treatment technology selection, and regulatory decision-making.
Plain English
Drilling holes at strategic spots around an old mine to take samples and learn what contamination exists underground and how the rocks and groundwater behave.
In Editorial Context
Technical fieldwork requiring careful documentation of methodologies, quality control procedures, and data interpretation in site investigation reports and remediation planning documents.
Etymology & History
Developed as environmental regulations required detailed site assessment before remediation, replacing earlier assumptions-based cleanup approaches.
Evolved from simple exploratory drilling to sophisticated investigation programs with real-time data collection and adaptive sampling strategies.
Usage
"The characterization drilling section required editorial review to ensure the sampling methodology and quality assurance protocols were clearly explained for regulatory reviewers."
Usage note: Specifically refers to investigation drilling, distinct from production drilling or remediation system installation drilling.
Context: site investigation reports, work plans, technical specifications, regulatory submissions
Region: international

Don't confuse with
May be confused with drilling for treatment system installation, which occurs after characterization is complete.
