Spletof field methods for the determination of TPH in soils. This was an ambitious project that involved the establishment of a TPH definition and the development of a reference se- lected for -846 Method 9074 (Lynn et al., 2002; 1996a). At present, a wide variety of specific and non- specific methods are used for analysis of TPH. Splet1). TPH concentration for the top soils (15 cm depth) ranges from 55 ±13 to 302±14 mgkg-1. The middle or sub-soils (30 cm depth) had a concentration range of 54±7 to 345±4 mgkg-1 and a range of 57±4 to 289±15 mg recorded for the 60 cm depths measured. Sample A11 and A3 had high TPH concentration with the middle soil (15-30 cm depth) and
