We have a high water table in my neighborhood. With a lot of rain lately, the sump pump is running constantly. This is a bit misleading …. Germicidal action only occurs when using the short wavelength UV-C. This wavelength does the job on bugs in water, but can also fry your skin in seconds. So be careful.
Save the black lights for gazing at neon pictures of Elvis. How about arsenic? I had my water lab tested three years ago and it measured 10x above the EPA min. I also believe nothing of what I hear and less than half of what I read. My reasoning may be wrong but it seems that rev. I told them the last time I heard that advice was on my meeting trips to Mexico when I was gainfully employed. Place green organic material around the sides of an open top 55 gal drum and a large mouth container in the center.
With a preferably black plastic bag and a string form a cone that covers the mouth of the drum attaching the string to the center of the cone, making sure the string reaches the container and tie a small rock or lure at the end just inside the container.
Will be safe. Most imp. I have put black plastic trash bags in my emer. Endless uses for those. Now another very imp. Note that this distilled water has no minerals: it is quite corrosive! With regular use it will dissolve the enamel from your teeth.
Hence, add some salt or a bit of antacid tablet to the water. Similarly, do not buy distilled water in the supermarket for use as drinking water. You can do he same thing with a hole in the ground. The Dew on the plastic will collect in the container. Insert a long straw in the container and leave it hanging on the outside of the hole. Need more water; dig more holes. Slip a large plastic bag over a bunch of Willow Tree branches tied together on the tree and you will collect water from the leaves.
Activated bamboo or bone charcoal is the best. One of them will even take fluoride out of the water. Those stainless steel drip-type ceramic filter purifyiers work very well, if you have the money.
Buy just the ceramic filter, Berkey is a common one. Buy, or scrounge, two food-grade five gallon buckets with lids. Put the filter element stem through the bucket and the lid and tighten the wing nut.
Set this assembly on the second bucket. Fill the upper bucket with the water to be purified and top with the second cover to keep the debris out. A fluoride after-filter can be added to the primary filter, if you are worried about fluoride.
Some people like to add a spigot to the lower side of the bottom bucket. I think it is just as easy to dump the filtered water into a carboy, and start another batch. Fill a pitcher with water and place a handful of cilantro leaves into the pitcher. Stir the water and let the leaves sit in the water for at least an hour.
Remove and discard the cilantro before drinking the water. Drain the water through a clay pot to remove bacteria. Clay and ceramic are porous materials that allow water to drain through, but they trap bacteria, protozoa, and sediment. Because they trap these contaminants, clay pots can be used to purify water, especially water contaminated with E. Method 3. Boil the water. Boiling is a great way to kill bacteria, viruses, and parasites from water.
Fill a pot with water and heat it over medium-high heat, or over a fire. Bring the water to a boil and let it sit at a rolling boil for about 10 minutes. Let the water cool before drinking. Boiling alone will not remove heavy metals or chemical contaminants from water, but boiling the water with the inside of a cactus could remove additional pollutants, such as arsenic.
Distill the water with a solar still. Distillation is an effective way to remove many contaminants from water, including heavy metals, pathogens, salt, and even radiation.
You can build your own solar still to collect and distill groundwater. All you need is a jar to collect water, a shovel, and a sheet of plastic.
A solar still will work best in damp soil that has lots of moisture to collect. Fill a clear and smooth plastic bottle with water. Twist on the lid, and place the bottle on its side in direct sunlight for six hours to kill parasites, bacteria, and viruses. This method works because the plastic acts to trap heat from the sun inside the bottle, and the UVA rays pasteurize the water. Method 4. Strain the water. Place the strainer over a bowl, and pour the water through the strainer to remove the particles.
Note that straining the water like this will only remove large particulates, not pathogens, heavy metals or other contaminants. Make your own filter. You can also make your own water filter to remove large sediment from water. You will need some supplies, but you can also use alternatives if necessary, including: Use birch bark curled into a cone in place of the bottle and cap Use a shirt or towel in place of the coffee filter Use nuts, roots, or grass in place of the filtration materials [16] X Research source.
Use sedimentation. Collect the water in a bowl or jar. Leave the water to settle for one to two hours. During this time, heavier particles will sink to the bottom, and lighter material will float to the top. To remove heavier sediment, gently and slowly pour the water into a clean bowl or jar. Stop pouring before you get to the bottom, as this will leave the heavier sediment behind in the original container. Include your email address to get a message when this question is answered.

This is the most effective purification method. But may be impractical if you need large quantities of water. It also requires a heat source, which you may not have in some emergency situations. If fuel or power for your heat source is limited, bringing the water to a boil will usually disinfect it, even if you cannot boil it for the recommended time.
Or add 4 drops of household liquid bleach for each litre of water, stir, and let it stand for 30 minutes. If the water does not smell slightly like bleach after 30 minutes, add 4 more drops of bleach and let it stand for another 15 minutes. You should notice a bleach smell.
Or use iodine or chlorine purification tablets or drops. You can get these at stores that sell camping equipment and at some pharmacies. Follow the instructions on the package. Purification tablets are not as effective as boiling or disinfecting with bleach. But they do kill some types of organisms. Or use water filters that can get rid of some microorganisms and improve the taste of water. There are many different types of filters.
