Americans have growing concerns over organic chemicals such as birth control pills and fertilizers contaminating their water wells. More recently the dangers of inorganic compounds such as perchlorate, a byproduct of rocket fuel, have trickled into the headlines and consciousness in America.

Israel's En Gibton, named after a centuries' year old water fountain outside the Israeli city of Rehovot, plan on making America's drinking water cleaner and safer.

Developed by scientists at Hebrew University, En Gibton's main product is ClayMix, a filtration compound made from clay and natural organic materials. The ClayMix attracts negative and neutrally-charged organic and inorganic ions, and locks them away on its microscopic cup-shaped surface.

The cost-effective solution uses environmentally-friendly raw materials and achieves the highest efficiency in removing dissolved organic matter in brackish waters, reports the company.

"It's medium-tech cleantech," says En Gibton's CEO Rafi Nevo to ISRAEL21c. Nevo also heads TreaTec 21 Industries, a company specializing in advanced electrochemical water purification systems.

What's especially attractive about ClayMix, he says, is that the groundwater, surface water and wastewater treatment solution requires virtually no input of energy - just electricity to pump the water through the system.

Contaminated water is an acute and growing problem around the world. ClayMix, however, claims that it has the power to sequester up to 99 percent of its targeted contaminants, such as pharmaceuticals and fertilizers, from water, versus a 60% success rate in the industry standard carbon-based solution.

As populations grow and industrial and military processes increase, more and more American underwater wells and aquifers are becoming polluted. More recently, perchlorates in America have entered the environmental hazard radar, especially in regions such as Colorado.

"Perchlorates found in the Colorado River area can accumulate in breast milk, dairy milk and lettuce leaves and is known to affect the thyroid," says Nevo, noting that water treatment facilities in Colorado are on his check-list for potential US-based pilot plants of En Gibton's solution.

Founded in 2005, En Gibton is located in Ashkelon at the Ashkelon Technological Industries Incubator. The company is also supported by Israel's national water utility via the company WaTech, which has been beta testing En Gibton's technology in Israel.

En Gibton has tested the ClayMix solution in laboratories on organic contaminants and is currently treating Israeli water wells from perchlorates with great success. This issue of perchlorates is a global concern, says Nevo. And shutting down wells that are contaminated can only be a temporary solution.

"Perchlorates bind to the water," he says, "they stay there and accumulate. It's expanding and dispersing, so it's not clever to shut down a well. [The water] has to be treated. Our solution makes it possible to reopen these wells and prevent the closure of operating wells."

I had city water the other day at a restaurant, I don't know about over there, but here it tastes like almost pure chlorine or like washwater! Who really knows what is in it? my grandmother has drank it for probably 50 years and she likes the taste.. but i was raised on well water and can't stand the taste.
I'm sure chemicals from the surrounding farms could probably leach into wells, but then again sometimes they are 200 foot deep or more, so most contaminates get filtered out naturally from ground rock... etc..

we have iron in the soil, so the water tastes like metal, or money and sometimes it is undrinkable.. I only use it for tea and coffee.

I do know that they directly dump sewage into our main water source and it is disgusting.. as for "perchlorates" i don't understand completely WHAT it is exactly, but it can't be good if it binds on to cells and accumulates!

How efficient is compost as a filter substrate?

I lived with a family in Jerusalem who had a complex, very expensive filtering system under their kitchen sink that ran at a frustrating trickle. What a pain and not worth the money - especially if you don't have the skill to maintain the system.

I'm sure you could devise a way to filter using natural resources.. just like well water gotten from below surface is removed of impurities throught trickling down..

here is something I stumbled upon that you could derive filtering info from...

of course, these are instructions for removing radiation from drinking water!!

uh-oh.. sandy soil doesnt' work and you need clay particles to be done properly..
I'm not sure about your soil comp. exactly.. you may have the right kind if you dig deep

here is another great article about 'storing' water and makes reference to the bible...

"Perchlorates found in the Colorado River"

This is very interesting. I actually saved the article from a newspaper clipping from about 2 to 3 years ago on this.
There used to be a facility that dumped the perchlorates waste into drums and buried the drums in the desert. As it turns out the drums over time are leaking out the poison into the underwater rivers that enter into the Colorado River that is a main water supply for California, Arizona, and then down to Mexico.
The water is not treated when it goes to our agriculture. Lettuce and other foods absorb the chemicals easily.
It is no wonder the amount of birth defects and other health problems issues that are on the rise.

Never mind the pesticides on the outside of the foods, what's on the inside?

Talking about purify, did you know Israel and the Ruskies have developed a system to neutralize nuclear waste and generate electricity at the same time? I've posted the article at http://ilenvironment.multiply.com/journal/item/26.
