The method used by archaeologists for excavation and recording of the stratigraphic evidence, within trenches with or without archaeological remains, can potentially be useful to contaminated land consultants (CLCs). The implementation of archaeological practice in contaminated land assessments (CLAs) is not meant to be an exercise in data overkill; neither should it increase costs. Rather, we suggest, that if the excavation and recording, by a trained archaeologist, of the stratigraphy is followed by in-situ chemical characterisation then it is possible that much uncertainty associated with current field sampling practices, may be removed. This is because built into the chemical stratigraphy is the temporal and spatial relationship between different parts of the site reflecting the logic behind the distribution of contamination. An archaeological recording with chemical stratigraphy approach to sampling may possibly provide 'one method fits all' for potentially contaminated land sites (CLSs), just as archaeological characterisation of the stratigraphic record provides 'one method fits all' for all archaeological sites irrespective of period (prehistoric to modern) or type (rural, urban or industrial). We also suggest that there may be practical and financial benefits to be gained by pulling together expertise and resources stemming from different disciplines, not simply at the assessment phase, but also subsequent phases, in contaminated land improvement.
考古学家在有或没有考古遗迹的沟渠中进行挖掘和记录地层证据的方法，对污染土地顾问（CLCs）可能是有用的。在污染土地评估（CLAs）中实施考古实践并不是为了过度获取数据；也不应该增加成本。相反，我们建议，如果经过培训的考古学家对地层进行挖掘和记录，然后进行原位化学特征描述，那么可能会消除当前现场采样实践中存在的许多不确定性。这是因为化学地层中包含了场地不同部分之间的时间和空间关系，反映了污染分布背后的逻辑。对采样采用具有化学地层学方法的考古记录可能为潜在污染土地场地（CLS）提供“一种方法适合所有”，就像对地层记录的考古特征描述为所有考古场地提供“一种方法适合所有”一样，无论其时期（史前到现代）或类型（农村、城市或工业）如何。我们还建议，通过汇集来自不同学科的专业知识和资源，不仅在评估阶段，而且在污染土地改良的后续阶段，可能会获得实际和经济上的好处。
