Is water quality testing really necessary? What can be detected from the water? What are the requirements of water quality testing for the environment and so on! Let's take a look at these questions together.

People often ask, is water quality testing really necessary? What can be detected from the water? What are the requirements of water quality testing for the environment and so on! Let's take a look at these questions together.

 

The Necessity of Water Quality Testing:

Provide water quality heavy metal detection, bacteria detection, toxic substance detection, etc., covering drinking water, tap water, well water, mountain spring water, hot spring water, industrial wastewater, and catering sewage. Water is one of the most important substances on earth. All plants and animals must have water to survive. Without water, there would be no life on earth. Besides drinking it to survive, there are many other types of water. No matter what kind of water, as long as the water affects people's daily health, it is necessary to carry out water quality testing.

 

Why should the pH Value be Tested for Water Quality Testing:

pH is the amount of free hydrogen and hydroxide ions in water. The pH is between 0 and 14, the lower the number, the more acidic the water; the higher the number. With a pH of 7, it is considered neutral and ideal for drinking water. The value means that when the pH is below 7, each number is 10 times more acidic than the previous number. Alternatively, when the pH exceeds 7, each number is 10 times the basis of the previous number. Humans have a high tolerance for extreme pH differences. Drinking strength ranges from 4 to 11. pH values ​​above this range can irritate the skin, eyes and gastrointestinal tract. A pH below 2.5 can cause irreversible damage to the skin and organ lining. Pipelines and infrastructure can be susceptible to pH levels exceeding the ideal 6.5-9.5, which can leach heavy metals and toxins into our water.

 

What is Water Turbidity:

Turbidity refers to the content of suspended sediments in a water body, which is of great significance to the survival of aquatic organisms. Suspended sediment can block sunlight from reaching aquatic plants, suffocate aquatic organisms, and carry dangerous pollutants such as lead, mercury, and bacteria. Turbidity makes water noticeably darker and we can measure turbidity with a turbidity meter.

 

What is the Conductivity of Water Quality:

Free ions increase the conductivity of water. Common conductive ions in water include sodium, chlorine, calcium, and magnesium. Increases due to increased dissolved salinity, as dissolved salts and other inorganic chemicals conduct electricity. Conductivity is a common measure of water quality.

 

Why should the Water Quality be Tested for Dissolved Oxygen:

Dissolved oxygen is the amount of gaseous oxygen (O2) dissolved in water. Oxygen can diffuse into the water from the surrounding air, be exposed to the air, or enter the water as a waste product of photosynthesis. Aquatic organisms need dissolved oxygen to breathe and decompose organic matter.

 

Why should the Water Quality be Tested for Temperature:

Temperature is an important consideration when evaluating quality. Temperature affects other parameters and changes the physical and chemical properties of water. Temperature fluctuations also affect the behavioral choices of aquatic organisms and the tolerance of aquatic plants. Some aquatic creatures may choose not to live in a certain body of water because the temperature is not favorable for them. High temperatures can also increase the solubility and toxicity of certain compounds.
