This report shows in details different methods that may be conducted in order to test the quality of the water. First of all, the water quality is defined by its characteristics. They may be biological, chemical, and physical. The water quality standards differ due to several environmental impacts. Physically, the first tested impact is temperature. It has a high influence on the quality since it may cause different type of pollution and will also have a high influence on biological activities. When the temperature of water will become very far from its acceptable range, there will have a direct negative impact on species and living organisms. The water temperature is inversely proportional to the dissolved oxygen level. The second factor that affects the water quality is the potential of hydrogen 'pH'. Many organisms are affected by their medians' pH. If the pH gets outside of its acceptable range, plants and animals die. It is divided into three categories: acidic (< 7), neutral (= 7), basic (> 7). When the median is acidic, it causes corrosion for the pipes and aesthetic problems. When the median is alkaline, the water will become bitter. Solids are divided into two categories: suspended and dissolved. They are present in lakes and streams. Suspended solids are particles that will be retained by filtering. It includes silts and sediments. Aquatic life is negatively affected when the level of TDS is high. They are mostly found in acidic rainfall like H+ and hard water like
