What Is Water Quality? - FAQ'S about Water Usage & Quality

  • What do we use water for?We use large amounts of water each day, as water serves many different purposes. We use water to drink, to do the dishes, to take a shower, to flush the toilet, to cook dinner and for many other purposes. But water is not only used for domestic purposes, humans also use water in the industries and in agriculture. In agriculture water is mainly used to water crops, but in the industries it serves many different purposes. It can serve as an ingredient of a product we produce, but it can also be a part of the whole production process. Water can be used to cool substances in the production process, for transportation and conditioning of raw materials, for boiling or cooking, for flushing, as a cleaning agent and for product transport by shipping. How much water does a person use each day? Americans use an average of 168 litres a person each day. For Dutch people this is about 135 litres. This water is used for different purposes.

  • How long can water be stored?One should pay special attention to how water is stored. Water should be stored in a cool, dark and dry place and it should be stored away from cleaning supplies and other chemicals. Water can pick up odors from other substances that we cannot detect in the air, so one should always pay attention to the properties of other substances that are stored with the water.

  • Why does tap water often smell like chlorine?Drinking water has to be protected from micro organisms and contaminants that can enter the water through the pipelines that transport it to households. This happens by means of disinfection with various disinfection agents, chlorine being the most widely used one. Chlorine is a very effective disinfectant, which is used to kill any harmful bacteria that might be present in the water source. The amount of chlorine that is used is based on the amount of water that is treated, the amount of contaminants that must be controlled and the time it takes for the water to reach the first house. Chlorine levels are usually low, but in some rural areas there are more dangers to drinking water and the levels of chlorine that are used are a bit higher. People can than smell it when they tap water. When one's tap water smells like chlorine it does not mean a danger to the people that drink it. Chlorine levels used in drinking water are not high enough to form a serious threat to anyone's health. If the water has a chlorine smell, it may actually indicate that not enough chlorine is being added to the system. By increasing the amount of chlorine used at the treatment plant, different forms of chlorine are created in the water, which diminish chlorine odors.

  • Which factors determine water quality? Water quality is determined by the presence and quantity of contaminants, by physical/ chemical factors such as pH and conductivity, by the number of salts present and by the presence of nutrients. Humans largely influence all these factors, as they discharge their waste in water and add all kinds of substances and contaminants to water that are not naturally present.

  • What is the difference between salt water and freshwater? Salt water is water that contains a certain amount of salts. This means that its conductivity is higher and its taste much saltier when one drinks it. Salt water is not suited to be used as drinking water, because salt drains water from human bodies. When humans drink salt water they risk dehydration. If we want to drink seawater, it needs to be desalinated first. Salt water can be found everywhere on the surface of the earth, in the oceans, in rivers and in saltwater ponds. About 71% of the earth is covered with salt water. Freshwater is water with a dissolved salt concentration of less than 1%. There are two kinds of freshwater reservoirs: standing bodies of freshwater, such as lakes, ponds and inland wetlands and floating bodies of freshwater, such as streams and rivers. These bodies of water cover only a small part of the earth's surface, and their locations are unrelated to climate. Only about 1% of the earth's surface is covered with freshwater, whereas 41% of all known fish species live in this water. Fresh water zones are usually closely connected to land; therefore they are often threatened by a constant input of organic matter, inorganic nutrients, and pollutants.

How is water quality assessed? To determine water quality, certified agencies take samples; small amounts of water in a medium which can be tested in a laboratory. Laboratories test these samples on various factors, and see if they suffice water quality standards. One of these factors is the number of colonies of coli form bacteria; these are an indicator for drinking or swimming water quality. Another factor is the concentration of certain contaminants and other substances.

What are water quality certificates? When water serves a certain purpose, such as swimming water or drinking water, people that use it need to know whether it is safe. A water quality certificate is a piece of paper that is given out by a certified agency for water quality assessment, after the assessments have taken place, when the company is content about the water quality. These certificates show people that water is safe to swim in or to drink. Water quality certificates are given out for example to pool owners. Bottled water sometimes includes a safety brand on the bottles, which shows that a certificate has been given to the supplying company.
