Colour

The colour data in the grease tap is significantly high. The main reason is because teachers use the tap water to wash their hands which may be dirtied with pen ink, food molecules, and other coloured particles.

A high amount of colour in the outlet could be due to organic matters, such as decaying leaves and suspended particles, such as soil.

Decaying leaves & Suspended Particles contribute to Colour Data

The inlet, pond 1 and pond 2 colour data is caused by suspended particles especially coloured clay soils.
