Water Quality

Water quality and radon: Implications for Scotland of the provisions and scope of the Council Directive 2013/51/Euratom for radon in drinking water

The European Commission published a new Directive under the Euratom Treaty (Council Directive 2013/51/Euratom, hereafter reported as the Directive) laying down requirements for the concentrations of radioactive substances in water intended for human consumption. As part of an on-going review of the implications of the Directive for Scotland, the Drinking Water Quality Regulator commissioned CREW to collate evidence on the presence of radon in drinking water and, create a map of ‘areas of likely high exposure’.

Innovative solutions for sustainable drinking water treatment at small to medium scales

Within the EU Horizon 20/20 program and The Hydro Nation Agenda water is seen as a significant enabling factor in the transition towards a resource efficiency and regenerative circular economy. While major urban managed water systems have seen
much improvement in performance, small to medium supplies still require optimisation. The research undertaken addressed the need to optimise the overall sustainability of small to medium sized water treatment processes.

A review of techniques for the monitoring of fine sediments: discussion document to inform workshop

Fine sediments (particles 2mm) in rivers and streams generally result from land management activities such as forestry, agriculture or development. Their ecological effects can be highly damaging (Owenes et al., 2005). In suspension, fine particles interfere with biological processes (e.g. reduced sunlight penetration impairs plant growth) and behaviours (e.g. restricting the ability to find prey). When deposited, fine sediments can smother the riverbed and restrict the infiltration of oxygen-rich free-flowing water.

Monitoring guidance to assess the effectiveness of the Rural Diffuse Pollution Plan

Water quality is generally good across Scotland. Yet, SEPA estimates that around 30% of water bodies are expected to be at less than the good status required by the Water Framework Directive at the end of 2015 due to the adverse effects of rural diffuse pollution. The most widespread diffuse pollution pressures include losses of nutrients, pesticides and faecal indicator organisms in runoff.

Scotland's Water Sector: An overview

The purpose of this research is to produce a map that demonstrates the scope and scale of Scotland’s water sector and demonstrates how the different parts of the sector link together. It demonstrates how the decision making processes that influence, manage and control Scotland’s water resources are distributed throughout the sector. This research supports the Scottish Government’s Hydro Nation Strategy.

CREW Annual Report 2012-13

Scotland's Centre of Expertise for Waters, CREW, delivers objective and robust research and expert opinion to support the development and implementation of water policy in Scotland. During 2012-13 CREW has supported policy teams working on Hydro Nation, flood risk management, catchment management and the Water Framework Directive, drinking water and waste water services, as well as wider policy.

Fats, Oils and Greases

There are approximately 200,000 sewer blockages throughout the UK every year. It is estimated around 75% are caused by FOG (Mills, 2010). Problems caused by FOG in the sewer system not only affect the performance of the sewer system and waste water treatment works (WWTW) but may also reduce asset life and increase maintenance costs. This will have an economic impact on the responsible water authorities and will ultimately be reflected in increased prices for customers.
