... What does the table 1 tell us about variations in water quality of rivers (a) between the different regions and (b) over the period in question. The table looks at five different regions over the period of just over a decade. It shows what the quality of water was like and if it improved or got worse through the mentioned factors. We will point out the important region of Anglia. It began as one of the average regions in 1990 yet had the lowest good quality water. It improved dramatically and increased its quality by 29%.
