The chart below shows the percentage of river water in UK rivers that is classified as having good chemical quality between 1990 and 2002 E3qdL
The given chart illustrates the changes in the proportion of river water in high quality in four different UK countries.
Overall, the percentage of good quality river water in Wales and Scotland showed a relatively stable trend, whereas the opposite was true for the figures for Northern Ireland and England, which showed some fluctuations.
From 1990 to 1998, Wales and Scotland had the best river water quality, which stood at exactly 95% and around 97% respectively. At this point, the figures for water quality in Wales dropped by roughly 5% to finish in third place, while the percentage of that in Scotland showed a steady increase up to 98% by 2002.
Moreover, England had the worst river water quality, which was just over 80% in 1990. Its figure fluctuated slightly until 1998, after which it rose to exactly 90% in 2000 and 2002. Finally, the figure for Northern Ireland experienced the most significant alterations, but generally increased by 5% by 2002, ended up being equal to the figure for Scotland.
