It is true that a healthy mangrove lagoon is a natural filtering system. Under normal circumstances, the water will appear opaque, reddish or brown in color. There will be an odor. When the system is disturbed, such as closing off the outlet with a road, filtration and natural degradation are affected. BOD (biologic oxygen demand) increases beyond the capacity of the system. Anaerobic bacteria multiply, causing an offensive odor. Not to say that sewage is not contributing to the problem, but how about a simple culvert system, allowing a transfer of salt and lagoon water to take place, maintaining the brackish environment?
