Contaminants in Public Water Systems - ASBESTOS

Worried about contaminants in the public water supply?  Well you should be.  What kind of contaminants?  Let's start with one that you'd probably never think you were drinking.  Let's start with ASBESTOS.  That's right the evil A-word!  You've all seen those lawyer commercials looking for mesothelioma victims to get a piece of that Superfund moola, but how is a mineral that is used in the manufacturing of materials like brake pads, floor tiles and roofing tars possibly getting into the public water supply that we're using to drink?  Well, that's the bitch of it.  Up to 82% of the water main pipes installed over the last 100 years until the late 1980's were reported as being asbestos containing materials (ACM).

These aging public water supply pipes are slowly degrading and releasing gazillions of asbestos fibers that are known to kill those who inhale or ingest enough of them.  So if this is true, then surely there must be some kind of maximum contaminant level (MCL) to ensure babies aren't being given a deadly dose of the mineral in their drinking formula, right?  Well, of course there is.  Don't be silly.  How irresponsible do you think the Environmental Protection Agency (EPA) is?  The MCL for asbestos in drinking water is a mere seven (7) million fibers per liter of water (MFL).  That's it.  Anymore may be dangerous to our health. Besides next time someone asks you what you had for lunch, you can be very witty and say: "asbestos".

Now let us sit back and think about what we do with this asbestos laced water.  So we've already thought about drinking it or otherwise consuming it by preparing food with it.  Let's see we also bathe and irrigate with it.  Hmmm.  That doesn't really seem to be a problem.  Although you know eventually that water has to dry up and all those asbestos fibers are going to be left over and blowing around in the air inside and outside of our homes.  

But how bad could it be to regularly inhale asbestos fibers?  Well, when an asbestos abatement is conducted by licensed contractors in public buildings such as schools, they are required to run a set of clearance finals within the containment unit where the asbestos was removed.  This involves the collection of at least five (5) air samples plus field/sealed blanks to be collected for analysis.  These air samples, collected through a filtered cassette with a minimum volume of 1200 L, are tested using a transmission electron microscope (TEM).  This thing zooms way the hell in there and an analyst quantifies the amount of asbestos in the sample.  Anything over the regulated limit of 70 structures per square millimeter FAILS.  Pretty strict for being inside a negatively pressurized containment unit with high powdered HEPA filtered air scrubbers.  They must be really worried about the toxicity of this shit.  

So what should we do?  Abatement workers are required to wear class C hazmat scrubs which consists of a tyvek suit, gloves, rubber booties and an air purifying respirator.  Not really something we can knock around in.

We can always use air sampling equipment in our homes to monitor the air via collection of TEMs.  Although, the lab analysis costs of over $500.00 a set would probably be more than most of us would like to spend.  Oh well, guess we are just doomed by this damned mineral.

CAREERS: TAKING A DEEPER LOOK INSIDE

Bhat Bangor, Student at the Indian Technical Institute of Bombay, India engaged in his studies.

Looking to start a new career?  Well, there's always work available as a medical professional. That's why we've selected the 'Medical Profession' to take a deeper look inside of this week.  But how do we become a medical professional? Take the gentleman pictured here, for instance. This student is studying for a rewarding career where he will learn to apply the most modern techniques and technologies toward the diagnosis and treatment of the diseases and illnesses that'll likely be plaguing folks like us in the future.

What appears to be an odd encounter between a young Indian man and a rubber anus, is actually an online introductory course on a cutting edge medical procedure that will surely save the lives of many, many people. While ensuring the patients comfort with gentle hands, a soft toned voice, and proper lubrication, Bhat Bangor performs an internal examination in search of any abnormalities in the patients rectum and colon. While doing so, the student also learns progressive multitasking skills that will boost his productivity. Here, while the patient is receiving an anal probing, the student also administers a vision test. This serves as a good distraction for patients as well as being an effective time saver which in turn reduces patient wait times (no one likes sitting in the waiting room when they showed up on time).

In addition to the common issues that may occur, Bhat is learning to deal with some unusually challenging situations requiring critical thinking and troubleshooting. During the anal probing segment of this computer generated simulation the patient over strained his eyes trying to identify the letters on the eye chart and becomes cock-eyed. Not to worry though, by utilizing a state-of-the-art tuning rod which produces advanced resonating frequencies in order to cause a mild trauma to the brain, the student was able to pull off a successful reversal of his cock-eyedness.  Later in the simulation a complication arises when a nurse turns on a microwave oven in which emits waves of radiation that caused the students probing tool to react like a jack hammer causing the patient to suffer severe rectal tearing and subsequent bleeding which required cauterization.  On a positive note, the vision tests indicated that the patient had perfect 20/20 vision even after having gone cock-eyed.

Although these simulations are designed to be exhaustive and require dealing with some unusual complications that may seem unrealistic, the experience gained will allow you to achieve your goals by being prepared for anything.  

We hope that sharing this story with you has inspired you to seek a new career today. Remember, you too have the opportunity to make a positive difference in the world in any career path you choose.

Next week's Careers will be taking a deeper look into the exciting world of legal prostitution. Hands on students please save your lube and anal probes as we will be reusing these items.
