National assessment of the potential problems to water supplies posed by low taste and odour threshold compounds - WT1275

The purpose of this study is to identify other compounds that may reach water sources and may pose a similar problem as EDD and EMD; to identify the quantities used, the industries that use them, any likely route into water and to give an estimate of the likely concentrations found.
Whilst this type of incident does not pose a risk to health but it may undermine public confidence in the water supply. Ensuring that “The public have confidence in their drinking water” is one of the strategic objectives of the Inspectorate that have been signed off by Ministers.
The objectives are to:

1) Establish a list of compounds of interest that have low taste and odour thresholds and could pose a similar problem to water sources as EDD and EMD;
2) Identify the quantities used and the industries that use them.
3) Determine the possible routes into the water system and
4) Estimate the likely concentrations found in raw and treated water;
5) Based on this analysis, produce a prioritised short list of compounds based on the likelihood of exceeding taste and odour threshold in treated water, that can be used to inform water company risk assessments
