ABSTRACT

This type of forensic investigation refers to practical situations in which the forensic investigation is conducted at sites where the potential exists for multiple releases to have occurred in time. These types of sites were in operation over many decades, with the same type of business conducted and the same type of contaminants handled during the years. The challenge is to point out releases that occurred in the past for which no documentation and no monitoring data exist. A typical example involves age-dating of older releases at sites with similar recent releases that may interfere and obstruct any potentially still existing older evidence. This forensic investigation type is strategically described in Table 14.1.
