Water Quality Problems

What Causes Water Quality Problems

In a global scale, the problem on water pollution has become a priority. Scarce potable water supply, industrial pollution, greenhouse effect and exponential growth in demand have been the subject of many debates and researches.

In smaller scales, these problems are being addressed as well. And the solution to these issues may one day help the global community.

Water Pollution and Its Causes


Sunlight is the primary source of energy in water-based ecological systems. Photosynthesis needs light in order to occur and for deeper lakes or ponds, light can only penetrate so much.

The main problem caused by lack of circulation in the water is thermal stratification. The water column is divided into temperature layers. The thermocline, or area between temperature layers, serves as a barrier for life to mix in the water.

As sunlight supports photosynthesis, the temperature of the top layer increases while that of the lower layer drops.

While life is supported on the top layer, the bottom layer loses out on more and more aerobic bacteria and oxygen. Organic matter builds up even more, while minerals and sulfides get dissolved.

An offshoot of thermal stratification that most lake and pond owners fear is seasonal water turnovers. When the conditions between layers become spectrally different, mixing the two will cause catastrophic damage to the pond life. Worst among all is fish kill.

Using aerators such as Air-Duck™ will allow circulation and prevent thermal stratification.

Nutritional Content

Nutrition is very important in the pond or lake ecosystem. The survival of water-based organisms needed to maintain the natural quality of the body of water needs adequate nutritional content. Slow digestion of organic matter allows sedimentation at the bottom and prevents the production of much needed nutritional content.

Using enzymes such as Pond-Zyme™ and Lake-Zyme™ increase digestion rates and keep the water healthy.

Anoxic Conditions

Low oxygen content clearly indicates poor water quality. Little or no living organisms at all may survive in water bodies with anoxic conditions. As the water gets harder and more minerals and salts get dissolved, the Dissolved Oxygen (DO) content becomes even lower.

Water-content hits a downward spiral as the issue with oxygen-content remains unaddressed. Algal bloom may occur under such conditions. Water aeration increases Dissolved Oxygen in the water and stimulates digestion of organic compounds.


Harmful microorganisms and bacteria may cause not only foul odor in water, but health risks as well. In places near industrial areas and poultries, there is a high risk of pathogen contamination and water pathogens can basically eradicate pond life. Pathogen increase may be prevented if water management products such as enzymes are used.

Chemical and Other Contaminants

Using fertilizers and chemical treatments may cause chemical contamination in the water. Not all substances from these types of treatment are beneficial for the water ecosystem. Increased acidity, accumulation of nitrates and phosphates, and water toxicity are a few of the problems that may be encountered with the use of such treatments. Natural products such as enzymes and aerators are a great alternative.
