Infrared Fibers Can Protect Against Chemoterrorism
Hugh Pickens writes "Although most Americans take the safety of their drinking water for granted, ordinary tap water can become contaminated within minutes, says Prof. Abraham Katzir of Tel Aviv University's School of Physics and Astronomy who has developed a fiber-optic system that can detect poisons such as pesticides in water in amounts well below the World Health Organization safety threshold using 'colors' in the infrared spectrum which distinguish between pure and contaminated water. 'With our naked eyes we can't distinguish between pure water and water that contains a small amount of alcohol or acetone. They're all clear,' says Katzir. 'But we can clearly distinguish between liquids using an infrared spectrometer which can distinguish between "colors" in the invisible infrared spectrum.' Connected to a commercial infrared spectrometer, the fibers serve as sensors that can detect and notify authorities immediately if a contaminant has entered a water reservoir, system, building or pipeline. 'Toxic materials are readily available as pesticides or herbicides in the agriculture industry, and can be harmful if consumed even in concentrations as low as few parts per million,' says Katzir. Cities like New York are especially susceptible to a chemoterrorist threat. With many skyscrapers holding water reserves on the top of the building, a terrorist only needs to introduce poison into a tank to wreak havoc. 'A terrorist wouldn't have to kill tens of thousands of people. Only 50 deaths — as horrible as that would be — would cause nationwide panic,' says Katzir."
Really? Chemoterrorist?
In the 50's was it Chemocommunist?
While there is almost certainly an argument to be made about the threat of threats being overblown, it'd be hard to argue that mass poisonings are anything but a bad thing.
I would, though, be fascinated to see if anybody ends up trying to shoot systems like this down, as delicately as possible of course. The overwhelming majority of toxins in the water supply are there as a product of industrial, agricultural, or "non-point" pollution, not any sort of terrorist activity(I can't actually think of any instances of such, beyond poison targeted at a few people, in prepared food or beverages).
If I were the maker of, say, a bevy of pesticides with rather dubious reputations, I'd be strongly against any sort of systematic, automated water quality sampling system. Same if I were a user of such. Industrial polluters likewise. How long before the American Chemistry Council, or equivalent, starts a "Waterborne toxins: Not really anything to worry about" campaign, urging citizens to "stand against irresponsible fearmongering" and bankrolls a bevy of innocuous and patriotic sounding "Citizens for Responsible Security" type organizations?

"Buy this university spin-off's product or your megacities will be susceptible to chemoterrorist attacks."
I'm going to go eat some undercooked steak. If I'm going to die (probably from heart disease, you know it's got 1/5 odds) at least I'm going to be happy. I really consider the fear of chemoterrorism to be so negligible as to not even be worth discussing.
Sure, with an IR spec read-out, you'll be able to tell that something new has got into the water supply. But what you won't be able to tell is what that contaminant actually is. For that, you'll need some sort of structure determination, as IR will only tell you if it has C=O or N-H bonds for example.
The reason this is important is that without the structure, you won't be able to tell whether a farmer has just switched to a different type of fertiliser, or the city has being trying out a new way to grit the roads, or whether you're actually dealing with a case of attempted terrorism. The only way this would be helpful would be if you could somehow be sure that only malicious activity would alter the chemical composition of your water, which I think would be extremely difficult in practice.
I don't know what their mothers feed them, but if Israelis can contribute in such ways - camera-in-a-pill, drip irrigation, Checkpoint software, Intel, Google enhancements, the life straw which cleans water as you suck - with everyone else wanting to smack them down, you'd have to wonder what they could achieve to better our lives if we all just shut the *&^% up and let them alone.

Things like this get me irked that we are spending billions upon billions each year on equipment, employees, and wasted time for all the added airport security since 9/11.
The fact is, is I were a terrorist I'd simply walk onto a bus or subway during rush hour with a bomb, like has been done in England and Spain. Effective, cheap, and little can be done to stop it. Not the same impact as collapsing two skyscrapers, but I seriously doubt any future plane hijackings will be successful since the rules have changed.
The overreaction to airplane hijackings is disturbing to me. The high school in my home town had a similar reaction to the Columbine shootings. They installed metal detectors at every entrance and hired extra security even though there had been little more than small knives confiscated at school, and never any real violence. Of course, there wasn't time to check people's bags properly, so it would have been trivial to smuggle something in anyway.
After two years at a cost of about 1.5 million per year, the metal detectors were taken out and the extra security measures scrapped. By then the public outcry for action had calmed, and no one wanted to be flushing 1.5 million down the drain every year.
I wish they'd do the same with the airport security. Lower it to a roughly pre-9/11 level, and spend the money elsewhere, like to keep nukes and dirty bombs out of the country.
It's a shame that a relatively interesting idea, has to be marketed as an ANTI-TERROR product for it to get any attention.
I can imagine this being useful for all sorts of problems related to drinking supply water - accidental contamination due to agricultural products, algal blooms etc
Another way to protect us all from the terrible imaginary threats - presented to us by the Chingers!

I wish somebody with a lick of sense would vet these ideas before they got out there.
All that's going to happen with IR spectrometers checking the water supply is a constant din of false positives, which will at first cause panic, then lethargy. Even a 0.001% false positive rate is way too high when you're trying to find a 0.0000001% signal.
Only 50 deaths â" as horrible as that would be â" would cause nationwide panic,' says Katzir
He's right ... but the only reason that's true is because we, as a culture, panic very easily. Granted, we're encouraged to do so by a sensationalist press, and a government that is always on the lookout for any rationalization for expanding its authority over us.
Sad commentary on the state of our society, I suppose, given that we mow ourselves down on the road by the thousands every year. That doesn't get anywhere near the media coverage, of course, even though automobiles cause more deaths per unit time than terrorism does (personally, I think some of the SUV-driving sociopaths I have to contend with every morning on the way to work ought to be up on terrorism charges, but that's another story.) We're all far more likely to die in an automobile accident than any probable act of terrorism.
In the end, dead is dead.

I worked on developing this capability for Process Analytical Chemistry for the food, petroleum, and pesticide industry twenty years ago when I worked for Perkin-Elmer Corp. It's currently owned by Hamilton Sundstrand and marketed under the name PIONIR. The samples are delivered to the spectral analyzer via NIR optical fibers, and other types of analysis are possible, too, including Fourier Transform spectroscopy and Raman spectroscopy. The analyzer can be as far as 200 meters from the samples. It's not cheap, though.

For a second, I thought this was the act of laying siege to a populous by randomly and callously treating cancers through chemical means.
BASTARDS!
Which is all exactly why these chemical corps would want the testing to be calibrated to ignore all their "normal" pollution, while the testing satisfies everyone that their water is "pure, perfectly safe".
Meanwhile, Bruce Schneier exposed the threat of "poisoning the water supply" as yet another "movie plot threat" that isn't at all a realistic priority for spending time, money, effort and credibility defending:
Just because we have the budget and the products to buy doesn't mean that's how we should be spending our necessarily finite resources defending the public. We'd do a lot better at least protecting our babies and pets from poisonous food exported from China.

Frankly, after hearing and reading about the water infrastructures of many major cities, NYC included, I strongly suspect such a system as this would be more readily useful in verifying that tap water is actually safe from pollutants caused by run-of-the-mill industry and poor water treatment / storage / transportation facilities. Good chunks of the NYC aqueduct system are 100+ years old, with some sections of pipe coming in from the Adirondacks still made of wood, fer cryin' out lout.
Sure, pesticides intentionally dumped in a reservoir are definitely a Very Bad Thing (TM), but polychlorinated biphenyl or polycyclic hydrocarbon aromatics are also *not* Part Of This Nutritious Breakfast (TM). There are plenty of nasties we've put into our *own* water supply, either out of cluelessness or laziness or greed, and new and easy ways of detecting these can only be good.

It is nice that on slashdot even terrorist can find some new technology...
But the whole point is to get to the houris...

Thank you for all the nice tips, Prof. Katzir. Who says there can't be any Jewish-Arab cooperation?
Free, as in your money being freed from the confines of your account.
You mean homoterrorism?
Yay for fearmongering! Teh terrists have won again!
Nothing against the detection technology, hey, it might even work, but the way it's sold is getting old and the sales pitch has proven costly to my precious bodily fluids, err, privacy and civic rights.
Submersible spectrometers are not new. In fact, I use them every day to monitor urban streams for pesticide and organic impacts. The spectrometers are easily applied to drinking water systems (in fact, easier than how we use them because drinking water doesn't have the same biofouling capacity as a river).
Nevertheless, the company we use sells their device as a 'UV-Vis multi-parameter' monitoring tool, not an anti-terrorism device. Sure, the equipment would function well in this application, but anyone with a clue could envision such a use without a pamphlet featuring a shifty-eyed, dark-complexioned figure.
All this company has patented is fear.

The whole "Bad Stuff in the water supply" bit. The problem with every scenario that I've ever seen for poisoning the water supply was that the sheer volume of toxin that would be needed to bring the concentration to anything near a harmful amount is always just plain enormous. Even if you used strychnine, you'd need to pull up to the reservoir with multiple tanker trucks and start dumpin'. You don't need fiber optics and infrared light to see guys dumping thousands of gallons of something into a large lake.

you mean in china they dutifully and calmly walk out of burning buildings?
in india they react to men running around with machine guns in icy calmness?
in europe the sight of exploding buses causes relaxing, calming effect
howabout AS A SPECIES, as a creature, a fucking mammal with adrenal glands and a healthy flight or fight response mechanism, we react the way we do, as a simple consequence of what we are
that renders all your faux regret pointless and useless: people panic. people have always panicked. people always will panic. why? because its a simple unescapable fact of us as living creatures with adrenal glands. we flip out not because of any sociological or cultural convention, ro anything that was ever taught, but as a simple consequence of inescapable biology
1. you know its a shame we can't build cities under water, that we are culturally conditioned to breathe air
2. you know its a shame we can't fly by flapping our arms, such has the media and our society propagandized us to walk around on our legs
those two comments make exactly as much sense as your opinion of the nature of panic
panic is a simple inescapable comppletely natural psychologicla and biological phenomenon. get used to it, don't bemoan it. especially since YOU ARE JUST AS SUBJECT TO IT
oh, you're not? you're a fucking cyborg? pffffft
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
so you are telling me when fall comes in 6 months in the northern hemisphere fatalities won't skyrocket? you know this as a fact? the spanish flu of 1918 followed the same progression: percolating below the radar over the summer, exploding in the fall when the flu virus survives longer in the cold air
and even if the fatality rate of this flu is wimpy, which seems likely, you are telling me that when it first appeared in march/ april, your opinion of the disease was spot on about it being harmless? you knew all the unknowns?
you know right now that the flu doesn't hold the potential to not only go pandemic, as this wimpy one obviously is, but not also viciously fatal? the chance is extremely low? but not zero, right?
the spanish flu had a low mortality rate too. and yet it killed millions. what if the next pandemic the rate is slightly higher? and everyone gets it at the same time: all the tamiflu, all the mechanical respirators: swamped out of avialability. nothing to worry about, right?
so who survives when such a hypothetical flu DOES EVENTUALLY arrive? well, i know that answer: certainly not you. those who survive will be those who healhty adrenal glands, who panic, hide and flee. it MAKES SENSE, it is INTELLIGENT to overreact in the face of UNKNOWNS than underreact. then the only thing we have to suffer are the bloviating hindsight know-it-alls afterwards, even if our "overreaction" might be the behavior that prevented more deaths!
your opinion, your hindsight, your certainty upon reflection are useless and arrogant. when the next pandemic appears, and it will, could take 10 years, could take 100, the influenza virus has many more tricks up its sleeves, one of them just might have a high mortality rate. and when that killer first appears many years from now, it will be virtually undistinguishable from how this wimply one appeared in april
and yet we have to listen to more hubristic assholes like you talk about the unknowns afterward as if you knew it all along
you don't represent intelligence. you represent an ignorant false complacency just as stupid and deadly as the false alarmism you skewer. we all know the cautionary tale of the boy who cried wolf. we need a new cautionary fable: the boy who cried sheep when the wolves were eating the flock, because his life of never experiencing any disasters in his life led him to assume this was an unchanging fact of human existence. ignorant bias
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
Imagine the disappointment of the terrorist who goes to all the trouble to break into the water tank in a high rise only to find out no one living in a high rise has ever drunk water from the tap. If only he could've broken into every 12 oz. bottle of water from the store.
lets boil it down to you simply:
false alarmism is retarded
absolutely agreed
equally retarded: false complacency
look, here's a mirror
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
