| I am suspecting the colours in alpha & bravo due to Green sulphur bacteria (e.g. Chlorobium sp.) containing green pigment ‘Isorenieratene’ and Red sulphur bacteria (e.g. Chromatium sp.) containing red pigment ‘Okenone’. May be due to higher sulphur content (extensive use of sulphur in ammunitions and explosives making) these bacteria are growing efficiently and dominated in one area due to their particular nutritional and other requirements. Like Purple-red sulphur bacteria normally respire anaerobically and the presence of oxygen hinders their growth. But if this colour either due to any reason is problomatic to you? if it is; in what sense? Further information like DO, TOC, pH etc will be more helpful to investigate the root cause.

| | If you would care to contact me off-line I will send you instructions on how to sample and send sample to me for microscopic analysis. I will analyze these for you gratis as my contribution to the effort in Iraq. As a disclaimer, my offer does not imply either an endorsement or a condemnation of what is going on over there. It is a purely humanitarian offer! |

| | Excellent discussion. I have three lagoons experiencing the same condition in the Empty Quarter. They were not red when I went on vacation three weeks ago. Although I suspected an algae bloom I was not sure as the color was so uniform. I unfortunately do not have access to a microscope to confirm but do agree that the addition of aeration units may resolve the issue if final discharge is contemplated. If no final discharge you may have to address odor problems which can also be addressed tgrough aeration. Cheers, Shaybah in the desert |

| | it very likely is red due to purple sulfur bacteria, which thrive in anoxic conditions. So the red lagoon may be that color due to heavier BOD loading. |
