I haven't had the spring water tested.

As far as diseases, botulism is down at the bottom of the list. The bacteria is common in the environment, but has minimal effect on adults, with high immunity.

The biggest issue is the botulism toxin which builds up in certain environments such as poorly canned veggies.

Running water isn't a place where botulism toxin builds up.

The far greater risk in the USA is Giardia. It can cause serious diarrhea in some individuals. It is unclear the level of immunity in avid outdoors people in the USA.

Some countries carry a risk of Hepatitis A, but primarily around untreated human sewage (generally not a problem with mountain streams in the USA).
I was generalizing -- Any organism or harmful particulate that's in the water.

Not all organisms are pathogenic.

Botulism is unique in that it may be pathogenic to infants, but in its natural state, it is not pathogenic to adults. It is only pathogenic if one allows the toxin to build up.

Likewise, Staph Aureus is moderately more pathogenic, but again, it produces a toxin that if it is allowed to build up, it can be problematic (generally giving one the runs).

You can eat eukaryotic algae. If it comes off in sheets, it tastes like lettuce.

Prokaryotic blue algae (cyanobacteria) is different.

If humans couldn't tolerate at least some organisms, we'd be in bad shape with a world full of them. In fact, some theories indicate that rural individuals get exposure to a wider assortment of microbes, and are healthier than urban individuals that get less exposure.

Many of the waterborne pathogens fall in a category called "fecal-oral" pathogens, and often cause diarrhea. Even so, many are species specific, or species preferential.

Hepatitis A, for example, is a fecal-oral disease, but is primarily a human/primate disease. So, if no humans have crapped in one's spring, then it is relatively safe.

I grew up drinking well water in the hills of western Mass. One time this:

My parents tried to convince us (the kids) that it was just that we had gotten used to the taste of chlorinated water when we were away. I know I had to mix it with OJ to drink it and when it took a hot shower the smell was nearly unbearable. Anyway after several days of tolerating we went up to the well to check it out. Turned out someone had slid one of the rocks open a bit to drop a pipe into. Looked down in there and there was a giant bloated possum floating. Fished it out and dumped a bucket of pool chlorine and flushed out the system. Still get nauseous thinking about it.

understanding the chemistry of water filtration will also tell you the ion-exchange resin in their filters create a good medium for growing bacteria which their tds tester has no capacity to measure and makes it even more important to buy their expensive replacement filters sooner than later and sterilizing the pitcher with a later filter change.

the building i live in uses a RO filtration method which also remineralizes the water post RO and directs water rejected by the system to be used in the toilets, landscape, balcony faucets etc…..which is a much better way of treating both drinking and shower water in a condo building or home and allows us to use the refrigerator's cold water dispenser without a filter.

There's a trail here called Granite Mountain Potholes that takes you to little puddles like @noisebeam showed, plus a view. In the mountains an itty bitty lake is a tarn, but call it a pothole and everybody will understand.

Here's a pothole on Trapper Peak, not big enough to be called a tarn. I did not drink from this. I'm very selective about when to filter. We have very clean water in the Cascades and it's a common practice to drink without filtering here in certain conditions.

Modern cases in the USA are generally imported from international travel or immigration, and it hasn't reached endemic levels.
Botulism is what he needs to prevent. Drinking in an Elk wallow might be risky without an effective treatment for the water . . . like fansidar is to malaria . . . but for botulism

Botulism is usually caused by canned foods that were improperly sterilized, not from drinking out of a questionable stream (sometimes referred to by local experts as a "crick"). I swear, this forum has become a hotbed of anti-Botulist misinformation lately.

For cyclists the most likely way to get botulism is from a baked potato wrapped in aluminum foil stashed in jersey for mid ride snack.

I don't think you'll ever let the facts get in the way of thinking your Zerowater test device is accurate. From my days working for a water and sewer agency: California requires its water providers to test the water in the treatment plant and at various points in the distribution system. They don't use a simple test device like you have, but either do a complete chemical analysis of it in their lab, or send it out to be tested at a contract lab (all labs are licensed by the State's Dept of Public Health). Either way, its more accurate that a device that comes with a water pitcher. BTW: The Zerowater test devices only measures Total Dissolved Solids (TDS), but the website doesn't say to what level it measures it. TDS has very little to do with the health factors of water, its more of a taste factor, so you are only fooling yourself if you think what you are drinking is contaminate-free. If you really want to know what's in your water then take a sample from outside your house, then one inside your house after filtering it, take them into a testing lab and have it analyzed (it ain't cheap to run all the required tests).

Working for a water utility, we spend a lot of money on water quality and testing. I have no issues drinking tap water here.

Don't think bottled water isn't just filtered tap water.

For legal reasons of course bottled water is just filtered tap water with a specified profile of minerals added back in.

I've let this go until now but for the record I really should say that a simple gravity fed water filter in a jug is not even close to being able to filter everything out of the water and produce a truly zero sediment reading. Only Reverse Osmosis filters can really filter out fluoride from the water. Some resin filters, kind of can filter out fluoride however they expire more quickly than you would like them to.

Any test kit giving you a zero reading from a simple gravity fed sediment filter is simply not a very sensitive test kit.

This is important if you want bad teeth and to avoid having your mind controlled by the government.

This assumes that the American Dental Association wants us all to have perfect teeth ... so that we'll never, ever need the services of one of their dentists.

Even IF you can find a Scientific reference demonstrating the benefits of adding fluoride to our tap water, what you are left with is, population wide medication against peoples will and without evidence that the medication is needed for all recipients.

Its a serious breech of Scientific and Medical ethics. Serious breech. Its no better than Religious people insisting that everyone MUST be Christian or their going to Hell.

In reality the best that the Fluoride compound that's added to our water supply can be is a broad spectrum antibiotic. Its not elemental fluoride as found in our teeth.
