While turbid water is not necessarily harmful, it can be a sign of more serious problems. Particles in turbid water interfere with the disinfection process because they shield harmful water contaminants, such as viruses and bacteria, from destruction by the disinfectant.
Bacteria are the most numerous organisms on the planet. There are literally millions of different types of bacteria. They are one-celled organisms and are present in everything from water to food, and on objects we touch every day. What’s ironic about bacteria is that they are among the smallest organisms on earth, and yet, they can cause some of the greatest problems.
All tap water contains unwanted particles and sediment that we’d rather not consume. Whether at home or in a restaurant, water from the tap always contains millions of particles, such as dirt and rust. Sometimes water even contains harmful particles, such as protozoan cysts, that can cause flu-like illnesses.
The presence of lead in drinking water is more prevalent and serious than many people realize. Despite common perceptions, lead is not restricted to inner-city communities, but rather is a problem that affects many water systems across the country.
Reverse osmosis, also known as “RO”, is a water treatment technique used since the 1950s to produce high quality drinking water that is virtually free from health or aesthetic contaminants. It is commonly used to treat water supplies that have a high content of total dissolved solids (TDS), such as brackish, saline or sea waters.
Cryptosporidium (pronounced krip-toe-spo-rid-ee-um) is a parasite that can live in the intestines of humans, farm animals, wild animals, and household pets. Although there are several species of Cryptosporidium, only one species, Cryptosporidium parvum, is known to cause infection in humans.
Although water may appear to be clear, it always contains many microscopic particles, some of which can make water taste funny and even be dangerous to your health. There are many types of particles, and the tiniest sub-micron sized particles may number in the millions per milliliter of water.
Nitrates (NO3-) and nitrites (NO2-) are chemical compounds that consist of nitrogen and oxygen. These compounds readily dissolve in water and have no taste or odour. Nitrate compounds are commonly used in fertilizers, food preservatives and chemical oxidants. A small portion of nitrate compounds are generated naturally in the soil by bacteria and by lightning discharge in the atmosphere.
Asbestos, which is a fibrous mineral sometimes used for fireproofing, has long been used to strengthen the cement used to construct water pipes. It was commonly used for this purpose until recently. Asbestos also is naturally found in some types of rocks and therefore is often found in well water and in surface supplies near mining operations.
