“…The unique vector iteration method has proven useful in application in a number of source apportionment investigations, particularly in air receptor modeling (Hopke, 1989;Chang et al, 1988;Borbely-Kiss et al, 1993;Moro et al, 1997). However, the method can be extremely cumbersome, especially in a situation such as Data Set 2, where a large number of variables (n 56) necessitates evaluation of the feasibility of many permutations of candidate source pro®les.…”

Environmental forensic analysis has evolved signi®cantly from the early days of qualitative chemical ®ngerprint evaluations. The need for quantitative rigor has made the use of numerical methods critical in identifying and mapping contaminant sources in complex environmental systems. Given multiple contaminant sources, the environmental scientist is faced with the challenge of unraveling the contributions of multiple plumes with overlapping spatial and temporal distributions. The problem may be addressed through a multivariate statistical approach, but there is a mindboggling array of the available``chemometric'' methods. This paper provides an overview of these methods, along with a review of their advantages, disadvantages, and pitfalls. Methods discussed include principal component analysis and several receptor-modeling techniques.

Environmental forensics has been defined as the scientific investigation of criminal or civil offenses against the environment. This broad definition encompasses investigations that run the gamut from arson to poaching to chemical contamination of natural resources. The scientific methods brought to bear in these investigations are also quite broad. In cases of arson, investigators may rely on traditional criminal forensic techniques such as fingerprints and tire tread marks. Poaching investigations increasingly rely on relatively new forensic techniques such as DNA evidence. Chemometric methods are common in environmental forensic investigations, in particular, in cases involving pollutant source allocation. The challenge is to determine how cleanup costs (or in the case of natural resource damage claims, redress costs) will be split among multiple, potentially responsible, parties. Regulatory agencies and potentially responsible parties seldom agree regarding equitable cost‐allocation. Similarly, potentially responsible parties rarely agree among themselves. Each party must make their case to a regulatory agency, an arbitrator, perhaps even a jury. The case inevitably depends on the analysis of huge amounts of environmental chemical data, and that in turn depends on environmental chemometrics.
