What does site characterization involve?

• A. No field work is required
• B. Only field investigation
• C. 1) Research into the history and use of the site; 2) Field investigation; 3) Laboratory analysis of environmental samples; 4) Evaluation of laboratory data
• D. Laboratory analysis only

Answer: (C)

Site characterization is the process of systematically gathering and integrating information about a site’s history, current conditions, and the distribution of contaminants to understand potential risks and inform decisions. The best description includes four integrated steps: researching the history and use of the site to identify potential sources and contaminants; field investigation to observe on-the-ground conditions and collect samples in the environment; laboratory analysis of environmental samples to quantify contaminants and physical/chemical properties; and evaluation of laboratory data to interpret results, determine the extent of contamination, and assess risk. This combination is essential because relying on history alone misses current conditions, field data alone lacks definitive contaminant information, and lab data alone lacks context and meaning without field observations and historical background.
