The line graph displays the changes in the proportion of river water in high quality in four countries between 1995 and 2018.

Between 1995 and 2010, the percentage of good quality river water in country A showed a very slight increase from about 96% to 98%. However, after that the percentage of good quality water started to decline and is predicted to reach 96% by 2018.

In 1995, the good quality river water in country B and country C stood at around 94%, but after that the percentage of good quality river water in country B has showed a steady increase upto the present time and has reached approximately 98%. It is predicted to show a slight fall till 2018. In contrast, the percentage of good quality river water in country C decreased moderately and reached a level of 87% by 2008. After 2008, the situation in country C improved and good quality river water showed a steady rise and reached 94% by 2013. This trend in expected to continue and percentage of good quality river water will soar to 96% by 2018.

The worst quality river water was in country D where 85% of river water was in good quality between 1995 and 2008. It peaked at about 92% in between in 2000. In 2008, the good quality river water in country D again showed a small peak but ever since has shown a slight fall and this fall is expected to continue in future also.
