Title: Swords water quality study - phase 1 : water quality of the Thames
Author: National Rivers Authority Anglian Region
Document Type: Monograph
This report aims to present a picture of the current water quality of the Thames and is part of the NRAs response to the south western Oxfordshire reservoir proposal (SWORDS). The report sets a baseline with which to compare the quality of the Thames when the reservoir is operational. The Thames was studied from Farmoor (upstream of the reservoir) and downstream as far as Egham. The data used was of two types. For July 1989 to June 1992 spot sample data for 17 sites have been analysed; and for July 1991 to June 1992 the data from 4 automatic monitors (AQMs) has been used. The AQM s record hourly sample results and since the volume of data for 3 years wouldve been too large only one year was used. Three of the AQM s are permanent and a mobile monitor was installed for August 1991 to July 1992 at Sutton Courtenay in the vicinity of the new reservoir. The three permanent monitors are at Northmoor (just upstream of the Farmoor abstraction), Cleeve (25 km downstream of the proposed reservoir); and Romney (just upstream of the intakes for the West London reservoirs.
