Thomas spoke about these in his article on purifying contaminated water. Basically, the reverse osmosis water purification systems, like the one featured as #5, will take care of larger contaminents. Couple that with ultraviolet disinfection and the rest of water purification is pretty well taken care of without requiring anything too expensive. Remember that this system requires electrical power, so you’re going to need to take that into consideration. But with a solar panel generator, it’ll do the trick perfectly.
Is it stereotypical that the AARP crowd would be the ones to spend three hours talking about metal detectors and canning and caving at a Pizza Hut on a Monday night? Probably, but that’s what I bore witness to in this event room; its combination of exposed wood and stock-photo decor felt like an Olive Garden inside a pirate ship. Up front, the scraggly white-bearded, Bad Santa–lookalike Andrew: rested one foot on a chair, gripping the mic, just like Randall said he would be. 
Although he had a cold when we met at his office in Harlem, Dr. Redlener was a soothing presence — bearded, erudite and open to the notion that ordinary people have a central role in emergency preparedness. The government, he told me, reacted decisively after 9/11, establishing the Department of Homeland Security, so why shouldn’t everyday citizens react?
_{Your list may be completely different from mine, but I believe the items contained in this list of supplies will be common to most people and more importantly will be required if you are going to be as prepared as possible if the manure hits the hydro-electric powered oscillating air current distribution device.  This list is not all-encompassing either. I am probably not going to have blacksmith supplies or leather working tools although I can see the use in each of those. This list is going to be for the average person to get by if we have a SHTF event, not start a new life in the wild west. Please let me know what additional items you would recommend and I’ll keep this list updated so you can print it out whenever you need to purchase items or want to build your supplies out.}
I would like to add, buying too much of something at one time. I have lots of water and food stored. Toothpaste, soap, qtips and such. How much medical and bandaid? NONE. Make a list most definitely. But include stuff you HAVEN’T BOUGHT yet. Checkmark items you have with the amounts. Also I have 3 non bullet weapons and have a 4th on the way. A regular size crossbow (with a broad head it will penetrate any class of body armor) A pistol crossbow which is actually more powerful than the large one, but you can’t get broad head for them. They will however penetrate 3/4 pressed plywood particle board. Good for human threat or rabbit get. A wrist rocket slingshot with “hunting” rubbers and I’m waiting on a new item called a “Pocket Shot”. It’s a new type of slingshot that self centers the ammo. You can fire almost twice the ammo in the same amount of time. All 4 will be valuable to be quiet during the first month. After the hordes have been thinned, noise from a gun will bring less attention.
And so, while I don’t think I’m newly paranoid, I am newly...prepared. Fortunately, the internet provides both camaraderie and online shopping for people who can vividly imagine literally every terrible scenario, and I quickly found myself down a rabbit hole of opinions on what I, my husband, and two small kids need, for, say, two weeks in an apartment with no access to food, water, heat, or medical attention. Or what we’ll need for a fast skedaddle out of town. But I persevered, and bought what I think is the bare minimum for health and safety in the event of a disaster. Below, everything I have in either my emergency supply kit or our “go bags,” or both.
_{It seemed important to know if this all-encompassing negativity was histrionic or appropriate — that is, if the hard-core Preppers I had met were crazy or were, in fact, on to something. Just before the show-and-tell, I came across a news report about Dr. Irwin Redlener, the director of the National Center for Disaster Preparedness at Columbia University, whom Gov. Andrew M. Cuomo had recently named to lead a commission investigating how ready the state was for another Hurricane Sandy-like emergency. I arranged an interview, figuring that he, if anyone, could answer my question.}
^{Despite a lull following the end of the Cold War, survivalism has gained greater attention in recent years, resulting in increased popularity of the survivalist lifestyle, as well as increased scrutiny. A National Geographic show interviewing survivalists, Doomsday Preppers, was a "ratings bonanza"[80] and "the network's most-watched series",[81] yet Neil Genzlinger in The New York Times declared it an "absurd excess on display and at what an easy target the prepper worldview is for ridicule," noting, "how offensively anti-life these shows are, full of contempt for humankind."[82]}

Jennifer didn’t get into prepping with a hurricane like Maria in mind. Her own personal SHTF moment — the calamity that spurred her to start stockpiling and growing food in the first place — was one that most people can relate to: the sudden closure of the law firm where she’d worked for several years. “We were down to only one income, so I said, ‘I have to really do something to help us get through this,’” Jennifer recalls.

#10 Wow, who to trust and how to meet those “truth worthy” people?? This one hit home. Due to various experiences with people from ever walk of life and every religious persuasion I’ve become a very distrusting person. So to even consider trusting someone, these days, I don’t know with the lives and safety of my family would be nothing short of a MAJOR miracle. Anyone else like me?? How do you over come that natural mistrust??

Of all the supplies they suggest you legally or illegally procure, epinephrine sounds like the biggest stretch. We don't want to burst anyone's bubble, but if you suffer from life-threatening allergic reactions and really think you're going to survive limited food sources and practically nonexistent medical care, we've got a mint-condition fallout shelter to sell you.
To remove solids such as dirt that are suspended in the water, strain the fluid through a T-shirt or a coffee filter. Portable water filters, like those offered by the camping gear company Katadyn, are also good to have in a pinch, said Rawles, and go at the top of his list because they are useful in "umpteen" different TEOTWAWKI breakdowns.
