For over 25-years, WRc has managed the Toxicity Advisory Service for United Kingdom Water Industry Research (UKWIR), providing advice on the human health effects, aquatic effects and fate and behaviour of chemicals in the event of chemical spills and pollution incidents. This service consists of:
- A 24-hour, 365-day/year response to both urgent and more routine enquiries on potential health effects associated with the presence of contaminating chemicals in drinking water, environmental water, their effects on drinking and wastewater treatment processes, and their taste and odour properties.
- Preparation and revision of over 600 Toxicity Datasheets on chemicals of interest to the water industry.
- Quarterly current awareness reports outlining new legislation and scientific developments tailored to the water industry.
One of the many unique aspects of this service is the generation of Suggested No Adverse Response Levels (SNARLs). SNARLs are unique to NCET and are estimates of the concentration of a chemical in drinking water considered to be of no significant concern to human health with consumption over defined short-term exposure periods such as might be seen in a drinking water contamination incident.
