Before deciding what makes good water quality, it's necessary to understand what makes terrible water quality. In particular, considering the three different types of Japanese koi ponds will help clarify the question. First, do you have a pond that you want to install for your enjoyment? If so, the question becomes more relevant if you know that plants are an essential part of your pond. Do you want plants like koi and orchids to live in your pond, or do you want to use artificial means to supply the food and oxygen they need?

The second type of question relates to water quality - eutrophic, acid, chlorogenic, and bactericidal. When talking about eutrophic water quality, you refer to levels of salt, calcium, and magnesium that support plant life. These levels are generally higher than those of acid, chlorogenic, and bacterial. To meet government guidelines for tap water, the groups should be no higher than 0.3 milligrams per liter. The average American household water company meets these standards.

The third question is about what kind of water quality parameters are used by your local water company. In the United States, the government sets the maximum safe levels for the three pollutants mentioned above. However, in Japan, there is no regulation of chemical and biological contamination. Consequently, the range of contaminant concentrations found in the waters has been widely described as "uneven and inconsistent." Researchers say there is a possibility that unregulated chemical and biological pollution may be one of the leading causes of cancer.

The fourth question is how to ensure that you are not exposed to excessively polluted water. One of the first steps is to install a filtration system that will remove chemical contaminants and physical characteristics that impurities tend to favor. The most effective filters use multiple steps to remove both chemical and biological factors. The best methods include a combination of granular carbon, ion exchange, sub-micron filtration, and a sub-micron filter.

The fifth question is why people assume that poor water quality is not something they have to be concerned about. The truth is that the risk to your health and the chance to the environment is far greater than the risk of obtaining a pure water supply. For example, drinking polluted water regularly causes gastrointestinal problems, liver damage, and other digestive complications. It also contributes to atherosclerosis, the process in which cholesterol clogs the arteries and contributes to the development of heart disease. The cumulative consumption of toxins over time causes many serious health risks, some of them deadly.

Although many water quality indicators claim to measure quality, only a few provide real value. Some of the more popular hands include pH, turbidity, total dissolved oxygen, and pH level. There are many other indicators, including sedimentation, mineral deficiency, lead content, and others, but none of these measures can accurately indicate how clean or poor the supply is. Only through carefully measuring and testing can you ensure that you have an adequate supply of clean water for your home or business.
