26-50%

Average Velocity:

0.66m/s

Physical Summary:

it was clear there was not much condensation and there was not too much soil in the water. mostly forested around the river, there was one big section of erosion but it was pretty much all clear, mostly healthy. (In other words: Gucci.)

Average Transparency/Turbidity

No Impact: >60 cm - 17cm = 0-50 ntu
Possible Impact: 17 - 8cm = 65-150 ntu
Impacted: 8 - < 6 cm = >150 ntu

Height of Water Column:

80.00cm

Turbidity:

6.00NTU

Chemical Assessment

Average Temperature:

10.00°C

Average pH:

6.00

Average Orthophosphate PO4-3:

0.04mg/L

Average Dissolved Oxygen:

10.00mg/L

Field Notes:

According to the test results of temperature, ph, orthophosphate and dissolved oxygen we discovered that the river has a good level of dissolved oxygen, the level is 10 which is a good level for the animals and the environment. with the ph the river is almost perfect because the level is 6. orthophosphate level is also good.
