It's no longer a matter of "if", but "when" a terrorist attack will take place on our drinking water or food supply. The recent pet food contamination crisis may well serve as a road map for terrorist to determine where our vulnerabilities are in our dietary supply chains. We should not be so naive to think that terrorist are not already considering our water sources as a potential point of entry to cause wide-spread harm to our general population. Point-of-use (POI) distillation is truly the only reliable source of protection with the numerous points of potential compromise (i.e. reservoir, treatment plant, water tower, water lines, bottling plant, delivery person, store shelves, etc.). Barrier methods of protection such as reverse-osmosis (RO) simply are not reliable enough to offer true protection in the event of a terrorist attack.

Water lines can be deliberately contaminated miles away from the water treatment facility or water tower. It is very easy to inject contaminants into the water lines, and once contaminated all users down-stream would be exposed. In this way terrorists can be target-specific. This method of water contamination is more likely than deliberate contamination at the reservoir or water treatment facility.

• Feed Water and feed water lines are contaminated by biological contaminants.
• Contaminated feed water enters the boiling chamber where it undergoes prolonged boiling, killing the biological contaminants where three things unique to steam-distillation occur:

1. Water changes phases from liquid (20) to vapor (steam) leaving behind residual contaminants.
2. Steam rises through a non-flow air-gap to separate feed water from distilled water.
3. Steam is condensed into high-purity drinking water.

Feed water is now contaminated with one or more biological contaminants.

The barrier and the seals may be totally effective in containing the organisms or it may allow some to pass through fissures or "streams" within the barrier. The user may not be aware of the contamination, and will have no way of knowing whether unwanted and possible dangerous biological contaminants have got through the barrier.

The contaminated barrier is now rendered "unusable" due to the unknown quality water produced by it. This is, of course, if the user is aware the water is contaminated.
