The scientists checked the dirty water from Kalaburagi City to see what was in it. They looked at stuff like how dirty it was and what harmful things were present. The water had a lot of organic material in it, with specific numbers like 380 for BOD, 510 for COD, 3200 for total dirt, 2000 for dissolved dirt, 220 for chloride, and 1200 for floating dirt. This means the water is not so clean and has lots of unhealthy substances that need to be taken care of.
