Water pollution events may arise rapidly, requiring a methodology that is easy to implement, fast to deploy, and
sufficiently sensitive to detect the trace presence of hazardous contaminants. A cheap and easy to use silicone rubber
(polydimethylsiloxane (PDMS)) miniature passive sampler is described. In order to test the methodology, pollutants
were concentrated, in situ, from surface water in and around Pretoria, South Africa. The versatile sampler allowed for
conventional and enhanced sensitivity, solvent-free analysis by comprehensive gas chromatography – time of flight mass
spectrometry (GCxGC-TOFMS) and high resolution TOFMS (GC-HRT). Contaminants detected in surface water include
caffeine, personal care products, pharmaceuticals, pesticides and polycyclic aromatic hydrocarbons.
