No, bacteria is onmipresent, i.e. everywhere on everything. Of course not all bacteria is harmful. Bacteria are 'large' compared to virus , being visible in a hobby microscope whereas viruses generally require electron microscope power to visualize. I try to get filters that realistically get down to 5 microns and also use bleach or other chemicals to kill organisms

Go back a bunch of pages in this thread and check out the results of the samples I plated in our lab. Some of those purifiers worked eerily well. I'm talking E. coli at >1000mg/l or "TNTC" dropping to undetectable levels.

Extreme emergency coupled with rudimentary filter, thoughts? I'm thinking for a rain water collection, or just "I haven't prepped and this is what I have around the house." Obviously the water source would have to be chosen carefully since metals or chemicals wouldn't be removed.

His information is flawed on too many levels to go in to, but I will mention the obvious (to water nerds)... Storing bleach in a clear bottle makes the contents questionable very quickly. Using bleach is useless unless the free chlorine can be tested. UV/sunlight eats chlorine fast.
Google Potassium Permanganate for water purification. Much easier to use and visual results are immediate.

What's best for long-term bleach? Tablets?

Calcium Hypochlorite- granular pool shock. Make sure the active ingredient is Calcium Hypochlorite, as there are several types of pool shock granules.
I searched the thread to see if this brand/model filter was mentioned but didn't see it. I've had a couple of these for years and they claim to be one of the few (only?) mechanical filters to remove viruses and cysts without chemical filtration.
Thoughts?

I used an AquaRain exclusively for 2 years while living in Mexico, never got sick. Poured all kinds of water in it. While traveling we used a First Need portable, again never got sick. You cannot control what they water the food with but in terms of drinking water we were good to go. Have used General Ecology filters for 20 years and they are awesome.
I would plan to hunker in place, have 5+ wooded acres, a creek in the back and a 30K gallon pool.

Is it possible to drink pool water since it's chlorinated already?.
Sure it's possible, but I wouldn't. Kids pee in the pool.
I'd worry more about chemicals added to the pool, like copper'based algicides, than otganic stuff if chlorine levels are properly maintained.

I don’t think a hand pump will pull it out from the average well depths now a days. AA county area I am in the older wells are around 60-80’. New wells 300’
Man 300’ of pumping or pulling, regardless you going to have an Amish sistermater sized arm.

I would drink it (after it has been run through a filter), I’m sure it has less chlorine than the water in Montgomery County

You can only "pull" water from about 33 feet deep because it is actually air pressure that is pushing the water up out of the well. (the approximate 15 PSI atmospheric air pressure is about equal to the weight of a column of water 33 feet high, water pressure is 0.433 pounds per foot of depth) When you need a deep well pump the pump actually goes down inside the well and the pumps water pressure pushes the water up the pipe. Same with a deep well hand pump the pump mechanism is down inside the well and the water pressure pushes the water up to the surface. Hand pumps use mechanical advantage to overcome the resistance.
The other choice is to live without water.
This will get you started:
Volunteer Village
AA County used to use shallow well hand pumps "Pitcher Pumps" then as wells got deeper they went to jet pumps that were electric with the pump at ground level, they had to be "primed", which would pump a stream of water down one pipe in the well casing through a venturi which would suck in additional water and out a second pipe in the well casing to the pressure tank. As water tables have dropped and people have tried to get away from the high Iron content the depth of wells has increased. Thus the need for deep well pumps with the pump located below the water table within the well casing.
If you don't like the convenience of a hand pump you could always use a well bucket:

I finally pulled the trigger on a water purifier. I got the ProOne (formerly Propur) Big+. It's 3 gallons total but that's split up between the purified area of 2 gallons and the water-to-be-purified of 1 gallon. So it really only stores 2 gallons of purified water.
With one filter it costs $229. Shipping was free.
It was easy to set up with good instructions. I used Star San Sanitizer on all the parts before putting it together. The instructions say to run 2 or 3 cycles and dump the water. I'm glad I did because the water was cloudy the first 2 cycles.
With only 1 filter installed it takes about 4 hours to fill the 2 gallon holding area for purified water. You will have to refill the input once. It has the option to have up to 3 filters. More filters reduces the time to purify but then you have to replace 3 filters every year. The first 1/2 gallon goes quickly, like within an hour, but the remainder takes another 2 hours or so. I think this is because lower surface area on the filter once the water level goes down. If you keep refilling it when it's 1/2 way down then it will go faster. But if you over fill it and the purified tank is full then it will start to leak out.
In addition to daily drinking water I'm also filling up these 4 gallon water bottles we got from the grocery store. Originally we got these so my wife could make beer with the water. Now I'm working on filling them and storing for stand-by water.
Overall I would recommend this. The 2 gallon purified water is a barely big enough for us 2 adults for a day. If you had more people in the home then I'd get something bigger. I plan on replacing the filter annually, they are $79 each.

This is going to start out unrelated but kind of zoom in on the issue of getting water. I'm not sure how many of you are familiar with DARC and specifically TUSC. DARC is a training company / org run by a former green beret. It's not so "gun training summer camp" type that other popular prior service members seem to popularize. It's pretty serious, high level stuff. TUSC is the tactical urban sustainment course. One of the main focuses is water safety/security, cause you can go without a lot of other things for a period of time, but as we all know we need water.
We've spent a lot of time on how to purify water, but I think only recently gotten to, how to get the water. I bring this all up to mention that a graduate of the course was previously an engineer who worked in africa with engineers without boarders and has previously worked in building water support systems in areas where clean water wasn't to be taken for granted, and has in my opinion, worked much of the problem / developed a key piece of the puzzle already.

I'll bet those strainers clog quick in the swamp. Plus the water still needs to be treated. I'll pass.
I make R.O. water with this compact system that's marketed to homebrewers. I bought mine at a homebrewers conference a bunch of years ago so it was a whole lot less than the current $400 system price. I also have the accessory TDS meter which reports the total dissolved solids going in, and coming out, of the system. Typical numbers are 350-450 ppm TDS going into the filter, and 0-5 coming out. The filter uses a carbon cartridge, a deionization cartridge, suspended solids, and an R.O. membrane.
I use the R.O. water for brewing (depending on the brewing method and beer style), for our coffee maker to dilute the charcoal filtered water out of our refrigerator, and to replenish the water in my 2 aquariums. I'll usually make 15-20 gallons at a time and use 2.5 gallon jugs and 3 gallon carboys to collect the output water, and either run the discharge water into the yard or collect it to water the flowers.
The advantage to this system is that it is self-contained and portable, I don't have space under our sink for an installed system, and I can use it anywhere there is a standard hose bib. The downside is that it uses proprietary cartridges which are kind of expensive.
