Nitrates
It is strongly recommended to avoid contaminated sources of drinking water. Methods for deleting nitrates: - distillation - ion exchange - reverse osmosis
Humans and other animals usually have bacteria that convert nitrates into nitrates in their large intestines. For adults, the presence of these bacteria in the digestive system is not harmful, because the stomach of an adult is so acidic that the bacteria cannot survive. But the stomach of an infant is much less acidic, so the bacteria can move up into the stomach, where they will convert nitrates into nitrites. The nitrites can then pass into the blood of the infant.
High levels of nitrates may be found in drinking water and can cause stomach problems in children. Heavy metals may also end up in drinking water with small levels being consumed on a regular basis.
the optimal level of tds in drinking water is between 75 - 150 . good luck.
Re-boiling clean uncontaminated drinking will water not cause cancer or any other health problems. However, boiling water contaminated with chemicals such as nitrates or toxic elements such as arsenic is a bad idea. Ground water may contain nitrates, which are chemicals often found in fertilizer, and arsenic that may occur naturally or from farm or industrial waste. Nitrates, along with nitrites, are also found in processed meats. Consuming water contaminated with nitrates can cause a blood disorder called methemoqlobinemia and some research shows that nitrates in drinking water may be associated with some types of cancer. Exposure to arsenic may result in arsenic poisoning and increased risks of several types of cancer. Nitrates and arsenic are not like bacteria, so boiling your water doesn't remove them. In fact, boiling water will actually increase the concentration. The more the water is boiled, the higher the concentration of these substances will be. The levels of both nitrates and arsenic are regulated and water supplies must be monitored in towns and cities, so if your tap water comes from a city water source, it is safe. People who live in rural areas and have private wells must have their well water tested for nitrates and arsenic. If you have a private well and the levels of these contaminants are too high, you must install a water filtration system for your home.
none. all nitrates are soluble.
Nitrates are ionic compounds soluble in water.
the answer is 29
60 -100 ppm is the currently acceptable hardness level for drinking water in US and Canada.60 -100 ppm is the currently acceptable hardness level for drinking water.
