A 73.29% Overall Water-Quality Index is almost 14% better than last year's results ! So as you can see, the river's quality is on a good path to becoming a clean and healthy river.

Neither of these results are 100% reliable though, because to get a true WQI you would need to sample the water at different times of the day on different days at different locations in the river.  We were unable to do this, but our result is a good rough estimate.
