This water filtration system has 7 stages of treatment, including an 11-watt UV light to zap any microorganisms that may be lurking in well water. While this isn’t usually a major concern for homeowners on municipal water, the conditions of a well sometimes harbor bacteria and microorganisms that could pass through your plumbing and into your glass. A UV sterilizer is an efficient, effective way to eliminate this risk and have more peace of mind when drinking well water.

After Hurricane Sandy, many homeowners used portable generators to replace lost power, leaving the machines running overnight and allowing odorless carbon monoxide to waft inside. The gas induces dizziness, headaches, and nausea in people who are awake, but "when people go to sleep with a generator running, there's no chance for them to realize that something's wrong," says Brett Brenner, president of the Electrical Safety Foundation International.
These survival tips can help you avoid becoming just another statistic. Accidents are the leading cause of death among U.S. men 18 to 50 years old, accounting for 37,000 of the roughly 148,000 annual fatalities. Some instances of unintentional death, to use the official term, are unavoidable—wrong place, wrong time—but most aren't. Staying alive requires recognizing danger, feeling fear, and reacting. "We interpret external cues through our subconscious fear centers very quickly," says Harvard University's David Ropeik, author of How Risky Is It, Really? Trouble is, even smart, sober, experienced men can fail to register signals of an imminent threat. Here we present 20 easy-to-miss risks, and how to avoid or survive them.
Hikers on a glacier or in areas where patches of snow remain above the tree line may be tempted to speed downhill by sliding, or glissading. Bad idea: A gentle glide can easily lead to an unstoppable plummet. In 2005 climber Patrick Wang, 27, died on California's Mount Whitney while glissading off the summit; he slid 300 feet before falling off a 1000-foot cliff.
Like most under sink reverse osmosis systems, you’ll need to clear enough space for the 3.2-gallon pressurized storage tank and the filter cartridges. But once you do, you’ll find that the rest of the installation is easy according to most reviewers. One user mentions that they move every 3 years but are happy to uninstall and re-install the system in each new residence due to the high performance and easy set-up of the iSprings RCC7AK.
Assuming you can get a fire going, and have a metal container. After filtering as many of the particulates as possible. Fill your container with water, place over the fire, bring to a rapid boil, then allow to cool (drinking hot water can induce vomiting). Boiling will kill the harmful bacteria in the water, as they cannot withstand the temperature.
U.S. Army Major Carl Rogers Darnall, Professor of Chemistry at the Army Medical School, gave the first practical demonstration of this in 1910. Shortly thereafter, Major William J. L. Lyster of the Army Medical Department used a solution of calcium hypochlorite in a linen bag to treat water. For many decades, Lyster's method remained the standard for U.S. ground forces in the field and in camps, implemented in the form of the familiar Lyster Bag (also spelled Lister Bag). This work became the basis for present day systems of municipal water purification.
Filter out pathogens with pine trees. Certain plants are effective at removing pathogens from water, and pine trees are among the best. To remove viruses and bacteria from your water, remove a small branch from a pine tree. Strip the bark from the stick and place the bare stick into a bucket. Slowly pour the water, letting it trickle onto the stick and into the bucket.[10]
The system came in a well packaged box and I found everything easily including some spare parts for future use, which I appreciate. Fittings and pipes were included. All I need was the tools (wrench, scissors, etc) and a Teflon sealer that I got from Home Depot. I noticed a little trace of water and I found out that iSpring did a real test for quality control so that's a good ... full review
Desalination – is a process by which saline water (generally sea water) is converted to fresh water. The most common desalination processes are distillation and reverse osmosis. Desalination is currently expensive compared to most alternative sources of water, and only a very small fraction of total human use is satisfied by desalination. It is only economically practical for high-valued uses (such as household and industrial uses) in arid areas.
The process of distilling seawater into drinking water has been used by the Ancient Greeks since about 200 AD (Wikipedia). Many cultures throughout history have used distillation as an effective method of ensuring potable water. Although the materials used in the distillation process have changed over time, the science has remained the same, proving that distillation is a purification method that has stood the test of time.

Only a part of the saline feed water pumped into the membrane assembly passes through the membrane with the salt removed. The remaining "concentrate" flow passes along the saline side of the membrane to flush away the concentrated salt solution. The percentage of desalinated water produced versus the saline water feed flow is known as the "recovery ratio". This varies with the salinity of the feed water and the system design parameters: typically 20% for small seawater systems, 40% – 50% for larger seawater systems, and 80% – 85% for brackish water. The concentrate flow is at typically only 3 bar / 50 psi less than the feed pressure, and thus still carries much of the high-pressure pump input energy. 

Prefiltration antiscalants: Scale inhibitors (also known as antiscalants) prevent formation of all scales compared to acid, which can only prevent formation of calcium carbonate and calcium phosphate scales. In addition to inhibiting carbonate and phosphate scales, antiscalants inhibit sulfate and fluoride scales and disperse colloids and metal oxides. Despite claims that antiscalants can inhibit silica formation, no concrete evidence proves that silica polymerization can be inhibited by antiscalants. Antiscalants can control acid-soluble scales at a fraction of the dosage required to control the same scale using sulfuric acid.[23]
My first path was to go with a Pelican combination whole house filter and salt free water softener. My plumber and others said whole house filter was the way to go for pure water and clear ice, not so much. Even Pelican suggested RO was not needed with the whole house filter. While I’m pleased with the Pelican system, the water is indeed soft and clean throughout my home, my faucets don’t ... full review
Countertop RO water systems are those systems that can be placed easily on the top of the Kitchen Table. These are designed for small families as they produce a small quantity of purified water. Countertop RO system is portable and inexpensive than most of other RO water filters. It is ideal for tenants who may not have permission to make changes in the house they live in.
STAT: The number of annual deaths from ESD in the U.S. are unknown, since they are counted among all drownings. But anecdotal evidence shows that ESD is widespread. ESD prevention groups have successfully urged some states to enact safety standards, including the installation of ground-fault circuit interrupters and a central shutoff for a dock's electrical system.

Installation went very well, although the manual was generic and not specific to the model I bought. This made the assembly a little longer as there were no specific photos pertaining to the 7 stage unit. Unit comes 95% assembled and all fittings installed. All interconnecting tubing is precut and most is preassembled. The included universal adapter fittings for your plumbing made drain hookup a snap. Total install under the sink took about 3 hours (drilling, electric, etc.). Don't forget the electric outlet! Zero leaks after install. As the instructions say, the first few cups of water will come out quite warm because water surrounds the ultraviolet sterilizer bulb and it is always on. Great for tea or coffee, less microwave time. Let it run for 10 seconds and you're good. I am getting about 2.5 gallons out of the unit before pressure drops. It still puts out after that, ... full review
Radium Removal: Some groundwater sources contain radium, a radioactive chemical element. Typical sources include many groundwater sources north of the Illinois River in Illinois, United States of America. Radium can be removed by ion exchange, or by water conditioning. The back flush or sludge that is produced is, however, a low-level radioactive waste.
