Water quality is determined by physical, chemical and microbiological properties of water.

A water quality index provides a single number (like a grade) that expresses overall water quality at a certain location and time based on several water quality parameters.

Water quality refers to the chemical, physical, biological, and radiological characteristics of water It is a measure of the condition of water relative to the requirements of one or more biotic species and or to any human need or purpose It is most frequently used by reference to a set of standards...

Physical characteristics of water (temperature, colour, taste, odour and etc.) are determined by senses of touch, sight, smell and taste. For example temperature by touch, colour, floating debris, turbidity and suspended solids by sight, and taste and odour by smell.

The chemical characteristics of natural water are a reflection of the soils and rocks with which the water has been in contact. In addition, agricultural and urban runoff and municipal and industrial treated wastewater impact the water quality. Microbial and chemical transformations also affect the ...

is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is disinfected for human consumption (drinking water), but water purification may also be designed for a ...

The most common chemical water treatments used by hikers and backpackers for drinking water purification are some form of chlorine, iodine, or oxidizing agents. All of these chemical water purification options require time for the chemicals to do their job. As a general rule you should wait at least...

Permanent water chlorination began in 1905, when a faulty slow sand filter and a contaminated water supply led to a serioustyphoidfever epidemic in Lincoln, England Dr. Alexander Cruickshank Houston used chlorination of the water to stem the epidemic. His installation fed a concentrated solution of ...

Ozone is an unstable gas comprising of three oxygen atoms, the gas will readily degrade back to oxygen, andduringthis transition a free oxygen atom, or free radical form. The free oxygen radical is highly reactive and short lived, under normal conditions it will only survive for milliseconds.Ozone i...

UV systems can destroy 99.99% of harmful microorganisms without adding chemicals or changing your water’s taste or odor?!
