Seasonal Lagoon Turnover
You may notice a strange and offensive odor emerging from the sewer lagoon this fall and early winter. This process is a seasonal event that usually takes place in the fall and spring. It is harmless to humans causing no more than an assault on the senses. When temperatures either begin to cool off or significantly warm up during the a change of seasons, turnover process takes place. Temperature layers in the water remain constant during the hot days of summer and early fall. As the surface continues to cool, the water in the top layer becomes denser than in the depths so it sinks which speeds up the turning process. Scientific studies show that oxygen in the water also stratifies with the warmer water near the surface containing dissolved oxygen, and the cooler water found deeper below the surface experiences oxygen depletion.
