Title: Humber estuary : environment quality report 1995
Author: Environment Agency North East Region
Document Type: Monograph
Abstract:
The Environment Agencys Humber Management Group (HMG), through its Environmental Quality Project Board (EQPB), co-ordinate Agency environmental quality monitoring of the Estuary. IMon-statutory Environmental Quality Objectives (EQOs), designed to protect existing and potential uses of Estuary waters, are used as reference points for comparison of results. Routine monitoring programmes of the whole Estuary, aided by intensive special surveys of smaller areas, provide data on the quality of the Humber including its tidal tributaries and freshwater rivers, its industrial and sewage inputs, accumulation of substances in its sediments and organisms, an d the nature and diversity of its invertebrate fauna and bacteria. The influence of the dry winter in 1994/95 was reflected in the rapid decline in flows during February. Flows remained low throughout the year and only showed a small increase in the last few weeks of the year. There was a deterioration in dissolved oxygen levels in the tidal waters probably related to low freshwater flows. Levels of all List I and List II metals complied with their respective Environmental Quality Standards (EQSs) except copper, which is an ongoing problem in the Estuary. Levels of synthetic organic compounds complied with the EQSs including Lindane on the River Aire at Snaith which failed in 1994. The biological quality of the tidal rivers remained similar to previous years suggesting no significant improvements in water quality.
