Review of England and Wales monitoring data for which a national or international standards has been set. - WT1207

Description
Drinking water standards set by other regulatory or advisory bodies often influence the development of European standards or UK national standards. However there may be an absence of monitoring data for England and Wales for some of these parameters and hence it is difficult to asses the impact of any such new standards.

To illustrate this point, the World Health Organisation’s (WHO) “Guidelines for Drinking – Water Quality” establishes guideline values for some 94 compound that may occur in drinking water. For the vast majority of these, about 55 compounds, monitoring of drinking water in England and Wales in conducted under the Water Supply (Water Quality) Regulations 2000. For the remainder, about 39 compounds, there is no routine regulatory monitoring conducted though they may be covered by ad hoc surveys, operational data, historic regulatory data or relevant raw water monitoring data. The purpose of this study is to identify sources of data for those compound that are not covered by the routine monitoring.
Objective
The objectives are to:

1) identify all compounds for which drinking water standards have been set by other regulatory or advisory bodies but are not covered by routine regulatory monitoring or that monitoring is not adequate. As a minimum the project should cover the following regulatory bodies WHO, USEPA, Health Canada and the Australian national authorities.
2) identify relevant studies and data, in the published and grey literature, including water company data, that establish concentrations of the identified compound in drinking water or water sources in England and Wales;

3) assess broadly the quality of the data and studies identified, in terms of the scope of the study and the performance of the analytical methods used and conclude on the likely levels found;

4) for any of the identified compounds where no data or inadequate data exist assess the likelihood of these compound being present in drinking water in England and Wales;

5) recommend whether further monitoring is required for any of the identified compounds.
