How to List Water Quality Testing As a Skill?

Water quality is the suitability of water for different purposes. This is determined by a variety of factors including its chemical, biological, and physical properties. These factors can directly affect human consumption, health, and industrial use. Typically, local governments enforce water quality standards. The purpose of these tests is to ensure that the quality of water is safe for human consumption.

Biological parameters 

Water quality testing involves the determination of the levels of bacteria, viruses, algae, and protozoa. Millions of microbes are present in water, and these contaminants can cause health risks. High levels of bacteria can lead to waterborne diseases. Hand washing is an effective way to reduce the risk of acquiring these diseases. 

The presence of foreign matter in water can alter the taste and smell of the water. These contaminants can be organic or inorganic and come from a variety of sources. Most of the foreign matter found in water is from agricultural sources. The electrical conductivity of water varies with the presence of different ions. If the dissolved oxygen concentration is high, the water is generally of good quality. 

Chemical parameters 

Water quality testing entails measuring various chemical parameters that affect the quality of water. These parameters include the color, taste, odor, temperature, turbidity, and solids, as well as electrical conductivity. Chemical parameters are also crucial for assessing the quality of water, as they measure dissolved oxygen and pH levels. Biological parameters include the presence of bacteria, algae, and viruses. 

Soluble oxygen, or DO, is a critical water quality parameter. High concentrations of dissolved oxygen in water indicate a high level of quality. However, the concentration of dissolved oxygen depends on several factors, including the salinity, temperature, and pressure of water. In order to measure dissolved oxygen, an instrument called a colorimeter or an electrometric method is used. 

Physical parameters 

Water quality can be determined by observing various physical parameters, including turbidity. This parameter is easy to detect, and high levels indicate high turbidity. The amount of dissolved oxygen is dependent on a number of factors, including the water’s salinity, temperature, and pressure. Using a colorimeter or electrometric method, a technician can determine how much dissolved oxygen is present in a water sample. 

Bacteria are one of the most common problems with water, and high levels of bacteria can cause a variety of waterborne illnesses. Bacteria are single-celled plants that can grow and reproduce rapidly. As a result, it is important to know how to test water samples for bacteria. 

Cost of tests 

While the cost of water quality testing as a skill is low, it is not free. The materials used for tests vary from $0.60 to $5.00 per test. This includes the cost of the materials used for presence-absence tests and quantitative tests. These costs are listed in Table 4. For example, the cost of H2S presence-absence tests is $0.62, while that of MPN testing is $1.25. These costs are within the ranges of other types of water quality tests, such as membrane filtration. 

The costs of water quality monitoring varied across study sites. In countries with large populations, operational monitoring of water supplies was the most expensive. Non-piped supplies, by contrast, required only two to four tests per year. 

Source of water 

Source of water quality testing as a skill involves the performance of various tests to measure the water quality. It requires knowledge of chemical analysis of water, computation of the total water quality index, and teamwork among members. It also requires knowledge of how to communicate results to other investigators using the internet. During the course, students will be trained to conduct nine different types of water quality tests. Upon completion of each experiment, students will calculate the water quality index of a body of water. These data are then shared with other investigators on the Internet and with the SITE program at Idaho Technical College. 

Water quality testing can be done in a laboratory or at home. Laboratory tests are more accurate and allow for multiple parameters to be measured. However, they are time-consuming and expensive.
