How To Contaminate the Hillsborough County Public Drinking Water System by way of a Double Check Valve.

The Hillsborough County (Florida) Board of County Commissioners is revising Ordinance 03-6 which relates to backflow prevention valves. For premises where the homeowners use County water to irrigate their lawns, the proposed backflow device will be the reliable, tamperproof and relatively inexpensive Dual Check valve, pictured at the left above. But for homeowners who have their own pumping system to irrigate their lawns from a pond, lake or well, which is also known as an “auxiliary water system”, the proposed ordinance will require a Double Check backflow valve on the right. The Double Check provides terrorists with direct access into the Hillsborough County public drinking water system. The County's "reason" for choosing the vulnerable Double Check valve is that it is "testable". Unfortunately, the very Test Port, indicated by the red arrow above, that makes the valve "testable" just happens to be the very same Test Port that provides direct access into the public's drinking water supply and is the very same Test Port that a terrorist, disgruntled person, prankster or even some high-school kids will easily use to over-pressure a contaminate back into the public drinking water supply to contaminate the water going to homes, apartment and office buildings, schools and military bases.

Both valves have been approved by the Florida Department of Environmental Protection for premises with auxiliary water systems.

These videos were made several years ago when you and I were trying to get the Florida Department of Environmental Protection to specify the Dual Check valve for residential use. They did do that. So please ignore the lead-in and lead-out which were directed at the Florida DEP. But now the Hillsborough County Pulic Utilities Department has decided to ignore the cost and danger to consumers. The videos refer to RP valves, but the Double Checks have the same Test Ports that provide direct access into the public drinking water supply. In the video for the refrigerator cartridge method of contamination, I refer to hooking it up between Ports 1 & 4. Actually, for an RP valve, it should be connected between Ports 1 & 2. But for the Double Check valve that the County proposes to mandate, connecting the cartridge between Ports 1 & 4 will still work to contaminate the public drinking water supply! Mainly consider the technical aspects put forward in the videos about how to contaminate the water supply.

Here are links to videos showing three different ways to contaminate the public drinking water supply using a Double Check valve.

As you view these videos, please bear in mind that I'm just the kid in the crowd and that it's the Hillsborough County Utilities Department that is the Emperor without any clothes!

Before 9-11, there were government analysts who warned their superiors about the potential of terrorists commandering passenger planes and flying them into skyscrapers. Unfortunately, their warnings were ignored. The events of 9-11 dramatically changed the federal governments viewpoint about domestic terrorism. The frequency of high-profile acts of terrorism has increased over the past decade particularly with the upsurge of homegrown terrorism in Europe (so far). Over-pressuring 55 gallons of chemicals or bio-toxins into a community's drinking water system in the middle of the night can be accomplished in less than two minutes through a Double Check valve. It certainly isn't as classy as flying passenger planes into the Pentagon and World Trade Centers - but it is easy to do, can be done by one person and can be just as deadly!
