Recently the US Military has developed a special set of sensors for water supplies for troops. Any time a base camp is set up it is important to monitor the water supplies and test them. You cannot simply test them when you arrive you need constant monitoring so that insurgents or enemies do not pollute the water or put poison in it. The three most common pathogens of water supplies are; Vibrio Cholerae, e. Coli and Giardia intestinalis and believe me you dont want any in your drinking water.

Two companies; Phase IV Engineering and Sporian Microsystems both in Boulder Colorado have developed a bio-sensor system which is RFID based. The device, which floats is connected to a Radio Frequency antenna and it is attached to a sensor housing which is submerged which is also connected to an anchor line. These water sensors can detect pollutants up to 1 part per million.

I propose these be used in the United States to protect our rivers and lakes, which contain drinking water. It is also important to have them in our wetlands and areas such as the Bayous in Louisiana and the everglades in Florida. Now then let us look at the efforts of the WHO, UN and World Bank; can we put these in third world nations to prevent waterborne diseases which kill millions of humans annually? If we can get the costs down significantly thru mass buying and economies of scale we are well on our way to eliminating the horrible issues that expanding populations in the third world face from polluted water and waterborne pathogens. As we see more severe and severe droughts in the world we will need to address these issues. We know have technology ready to be transferred thanks to our military expenditures thru DARPA.

We must continue to fund such research and boost such budgets of DARPA so that all of mankind can benefit in the offshoot transfer technologies. Think on this, something must be done.
