No. Hot water may contain impurities that come from the hot water heater and plumbing in your house. To avoid this, use cold water and let the water run for a couple of minutes before you use it if that tap has not been used for a while, overnight, or all day. You can then heat this water in the microwave or on the stove. Catching the water you flush out of the tap in a container and saving it for plant watering is a good conservation measure.

Hot water generally comes from a hot water heater that may contain impurities that should not be ingested. Some of these impurities might be metals from household plumbing that are concentrated in the heating process. Additionally, these impurities from the household plumbing dissolve more rapidly in hot water than cold water causing the amount of impurities to be higher in hot water. Therefore, cold water should be used for all drinking and cooking uses, as well as for baby formula. See similar questions...

Hot water is more likely to contain iron, copper and lead from your household plumbing and water heater because these contaminants generally dissolve faster into hot water than cold water. Therefore you should only use cold water for cooking. See similar questions...

Household water heaters heat water for washing, not for drinking. Water out of the hot tap generally has health-threatening levels of heavy metals (such as lead), as well as an off taste. You should consider this water unfit for human consumption. Incidentally, if you live in the United States in a house whose plumbing system was constructed between the 1930s and the late 1970s, it's a good idea to let the cold tap run at full for about a minute before using it.

Water can contain fluoride in varying amounts. Consult with your family physician or pediatrician to see if this is the most appropriate water to use. After their first birthday, children can drink infant formula mixed with water that contains fluoride because they weigh more and formula is no longer a primary part of their diet.

Yes, it is okay to use hot water to wash your Fuzzi Bunz, even on the hottest setting. However, keep in mind that you should dry your diapers on a low setting in your dryer. See similar questions...

Relatively inexpensive conductivity meters are available. They will give you an approximation of your TDS in your water and fertilizer mix. The short answer is yes, unless you have a sodium-based water softener. See similar questions...

According to the US Department of Agriculture, the majority of milk products originating from countries affected with Foot and Mouth Diseases are prohibited; however, Plant Protection and Quarantine has been instructed to provide some exceptions including "Milk and milk products intended for use by infants or very young children are enterable (into the U.S.) if in a reasonable or small quantity for several days' use".

No. Charleston Water System uses chloramines (a mixture of chlorine and ammonia) to disinfect drinking water, which are harmful to fish and other aquatic life. There are a number of products available at pet stores to remove chloramines from your fish tank. Charleston Water System tap water is safe for dog, cats, and other non-aquatic pets.

This is not recommended. The cloudiness that occurs is because of the silver reacting with the chlorine in the water creating silver chloride. The salt method also produces a gray cloud. The boiling method produces a clear or light golden colloidal silver. Heat 16 ounces (500 ml) of distilled water to the boil-preferably in a non-metal container. Do not use a glass measuring cup on the stove top as it may explode. See similar questions...

It depends on the iron. It is not recommended in models that do not have a self-cleaning or automatic cleaning feature. These features ensure that all calcium and lint deposits are removed. See similar questions...

Short answer--No! There are a number of "nasty" micro-organisms, especially acanthomeba (sp) which likes feeding on corneal tissue. Storing lenses in water also defeats the purpose of using a disinfecting solution as there is no disinfection occurring. If anything you are exposing your lenses to more potentially dangerous microorganisms. See similar questions...

Yes. It would be extremely difficult for a bioterrorist to contaminate our drinking water supplies to cause widespread illness. Huge amounts of water are pumped daily from our reservoirs, most of which is used for industrial and other purposes. Anything deliberately put into the water supply would be greatly diluted. Poisoning water supplies would require truckloads of biological or chemical agents that are difficult to produce and relatively easy to detect. See similar questions...

Tap water is not automatically safe. It may be contaminated with chemicals, bacteria, viruses, protozoa, and dirt. Have your tap water tested by a laboratory. Then ask a water company to design a filtration and purification system based on the lab results. If your water comes from a well, it may be necessary to have it softened, which means eliminating hard elements like calcium, iron, and magnesium. See similar questions...

WATER FILTERS: One way to avoid fluoride from the tap is to purchase a water filter. However, most water filters will not effectively remove fluoride. For instance, Brita filters will NOT remove fluoride. The two types of filters which will reliably remove more than 90% of the fluoride are reverse-osmosis filters and activated alumina filters. Thus, if you are looking for a filter to remove fluoride, make sure it uses "reverse-osmosis" or "activated alumina" technology. See similar questions...
