Check how it looks. The appearance of the water is not a guarantee that it is safe to drink, but water that is clear, free of surface scum or debris, and has no odour is more likely be to free of contaminants than cloudy, smelly water that has visible surface scum.
What are the symptoms of water-borne illness? Symptoms may include diarrhea, cramps, nausea and possible jaundice and associated headaches and fatigue. Symptoms may appear as early as a few hours to several days after infection and may last more than two weeks.
Clear and Odorless Water
One of the most apparent signs of healthy drinking water is its clarity and lack of odor. If your tap water is clear and has no strange smells, it is likely safe to consume. However, it's important to note that some minerals, such as iron or sulfur, can cause a slight odor or discoloration.
Often county health departments will help you test for bacteria or nitrates. If not, you can have your water tested by a state certified laboratory. You can find one in your area by calling the Safe Drinking Water Hotline at 800-426-4791 or visiting www.epa.gov/safewater/labs.
Alkaline water may be one of the healthiest waters to consume. The pH level of regular drinking water is a neutral 7. Alkaline water has a pH level of 8 to 9.5. It contains properties that may even protect your body from free radicals, which are often linked to inflammation and many chronic diseases.
Boiling is sufficient to kill pathogenic bacteria, viruses and protozoa (WHO, 2015). If water is cloudy, let it settle and filter it through a clean cloth, paperboiling water towel, or coffee filter.
Use a state-certified laboratory to test your water. Local or state health departments or environmental departments often test for nitrates, total coliforms, fecal coliforms, volatile organic compounds, and pH.
While tap and bottled water isn't perfect, experts say drinking from the tap is usually the better choice. “By and large, tap water is safe,” Kauffman says.
Bacteria will grow more in warm water, especially if any chlorine has evaporated. Therefore it's best to discard any warm water that's been left open for more than 12 hours.
If you don't have bottled water, bring tap water to a rolling boil for 1 minute or 3 minutes if you're at an elevation above 6,500 feet. Let the water cool off before you use it. Make sure to boil tap water, even if it's filtered.
There are corrosion monitoring kits too that can test multiple elements like alkalinity, temperature, calcium hardness and many other dissolved solids in the water. There are even comparison test kits, pH meters and pocket TDS meters to check if the water meets acceptable standards and is safe for drinking.
It's possible that this water contains small amounts of dust and debris from the storage tank in your home. Therefore, while there's no harm in drinking water from a bathroom tap at home once in a while, it's much safer to drink water from your kitchen tap connected to the mains.
Long-term consumption of distilled water might lead to mineral deficiencies since it doesn't replenish the body's mineral needs. It's generally safe to drink distilled water occasionally, but it's wise to ensure your diet provides adequate minerals as well.
Key points. Rainwater is not necessarily safe to drink without first removing germs and chemicals from it. Regularly test your rainwater for germs and chemicals if you drink, cook, or bathe with it. How you set up your collection system and proper maintenance can improve the quality of your rainwater.
Water testing
If you want your water tested you should contact the water company. A list of water companies in England and Wales can be found here. You can have the water tested privately for which there will be a charge. You can find your nearest approved laboratory here.
You can, at times, see, taste, smell, and feel contaminated water. Water that is red, orange, yellow, brown, or cloudy can signal iron, rust, or other contaminants in the mains or your household plumbing. Tannins from decaying vegetation and leaves can also give water a yellow or brownish hue.
Testing for water quality is done annually, and the results are sent to every customer in a Consumer Confidence Report (CCR). You can check the website of your local public water system for a current CCR. How does tap water get to the faucet?
A properly hydrated person with an almost full bladder will need to urinate between five to fifteen minutes after drinking water. But for someone who's dehydrated with an empty bladder, it could sometimes be up to nine hours before needing to urinate.
Dehydration happens quickly, causing extreme thirst, fatigue, and ultimately, organ failure and death. A person may go from feeling thirsty and slightly sluggish on the first day with no water to having organ failure by the third.
