Examine the source of our drinking water with the samples taken from the river

MAIN POINTS A 10 ml cylinder was loaded with sample of the water to be tested at 3pm. Two tablet of DO were added to dissolve. Therefore the color changed into pale pink. At this point the DO of 4ppm was confirmed. By checking the result with the table of data that crossed the Water Temperature a DO between 41% and 42% was approved. At the same time and with another cylinder that was filled with the same water a tablet of pH was added this time to inspect the acid base balance. The result was a range between 8 and 9. The turbidity of the river was tested with a can that was sunk in the depth of 20 cm .at the bottom of the can there was a black circle that after 5 minutes of remaining at the river slowly turned in to dark gray or pale black. After pondering the color the turbidity of the 40 TJU was obvious.
