Staged development - UKTAG reports on environment standards and conditions

UKTAG is developing its proposals for UK environmental standards and conditions in stages.

This is because, in some cases, progress depends on the completion of the classification schemes, outcomes from intercalibration or on European negotiations on daughter directives.

The table below summarises what is contained in Phase 1 Final Report (Sept 2006) and what is planned for later in 2007.

Environmental condition	Category	Report (Phase 1)	Future reports
General water quality (General physico-chemical quality elements)	Rivers	Biochemical Oxygen Demand and Dissolved Oxygen, Ammonia	Other nutrients Temperature Salinity Turbidity
		pH
		Nutrient: phosphorus
	Lakes	Dissolved oxygen	Transparency Temperature Other nutrients
		Salinity
		Acidification
		Nutrient: phosphorus
	Estuaries and Coastal	Dissolved Oxygen	Transparency Temperature Other nutrients
		Nutrient: nitrogen
Water flow and water levels	Rivers	Change from natural flow conditions	Compensation flows
	Lakes	Change in the outflow from the lake
	Estuaries and coastal		Hydrological inputs to estuaries
Physical structure and condition of the bed, banks and shores (morphological quality elements)	Rivers	Type and degree of physical alteration
	Lakes		Type and degree of physical alteration
	Estuaries and coastal
Chemical pollutants
Toxic pollutants (called Specific Pollutants)	Rivers, lakes, estuaries and coastal		Standards for pollutants discharged in significant quantities
Groundwater
Water balance and water levels	Groundwater		Groundwater standards
