Optimising Laboratory Testing – the best value for money

There are several areas of laboratory testing whereby site staff are not always aware of best practice or the most efficient use of differing tests in the laboratory, and several issues crop up frequently. These include incorrect sampling or storage, not specifying if water samples should be filtered or unfiltered, selecting an inappropriate form of TPH testing, confusion over the meaning of ‘total’ as applied to the inclusion or exclusion of sediment in water, and total as applied to total metals or speciated metals, and which is the most appropriate form of nitrogen compounds, and finally, whether total or water soluble sulphate is the better option.
