What Water Quality Issues Does Your
Water Resource Have?

Unpleasant taste or odor?
Excessive or toxic algae growth?
Manganese, iron or hydrogen sulfide?
Wide pH variations?
Periodic fish kills?

Surprisingly, these varied symptoms have a common cause:  lack of dissolved oxygen in the lake or reservoir. Here's why . . .

Taste and Odor Issues
The most common symptom of an unhealthy lake or reservoir, taste and odor problems can be the result of algae in the water.


Algae Blooms
A wide variety of algae are responsible for taste and odor complaints. Some types, like blue-green algae, are dangerously toxic. Algae growth can be due to excessive nutrient availability, lack of water movement or internal nutrient recycling due to a lack of oxygen in the bottom water.
Manganese, Iron or other Elements
In a healthy lake or reservoir, manganese and other minerals are limited to the bottom sediment. When there is a lack of oxygen in the water above the sediment, the element is chemically reduced to a soluble form and enters the water column. Removing manganese in the treatment plant is normally done with hazardous, costly chemicals. If not adequately removed in the treatment process, it can pose major problems to consumers when it comes in contact with chlorine -- turning clothes in washing machines and water in swimming pools brown. Many of these issues can be addressed by maintaining adequate oxygen levels in the reservoir. In addition, filter runs are increased, less treated water is wasted during flushing and less sludge is created.
Wide pH Variations
Fluctuating pH levels are the by-product of algae growth cycles. Reducing or eliminating these problematic plants effectively minimizes pH and other chemical variations in the treatment plant, saving the time and expense of constant monitoring and adjustment.


Periodic Fish Kills
Like many of the symptoms of an unhealthy lake or reservoir, widespread fish deaths can result directly from lack of dissolved oxygen in the water, or from exposure and consumption of toxic algae.
Each of these symptoms of insufficient dissolved oxygen can be eliminated or significantly reduced through use of our aeration technologies. Our engineers will help determine which oxygen diffusion systems will best meet the needs and goals of your water resource.
