While watching the US open golf tournament this past weekend some might have seen as interview with PGA president. His interview center around golf course sustainability, and highlighted the scarcity of water. In an effort to conserve water several prominent golf courses now are using reclaimed waste water for course irrigation systems. This change in golf course maintenance highlights the emphasis we all should start examining about water conservation and green alterative for use of fresh water. Below are a few examples recent examples of new technology and using nature to obtain and filter water.
Fresh Drinking Water from Air?
Water out of the tap, though convenient and a modern marvel, just isn't good enough. We can do better. And we certainly try to: from filtered water pitchers to UV water systems, our options for home-based drinking water has never been more abundant. And that's not even considering bottled water–either in little single serving sizes, or those gigantic bottles that are hard to lift. There are pros and cons for each of these water delivery methods, which would imply that the concept could be improved upon.
Taking water directly from the air, the EcoloBlue 30 Atmospheric Water Generator combines a water cooler and a filter pitcher, and it requires no indoor plumbing to work. Utilizing a 12-stage filtration system, the water cooler starts by dehumidifying the air and sending the resulting water through a series of filters.
Air first enters the machine by passing through an electrostatic air filter, removing airborne micro-particles and dust. Water is extracted using food-grade condensing coils and from that point on is subject to a series of filters and UV-C sterilization lamps. After passing through charcoal filters, carbon filters, a mineral filter, and a reverse osmosis membrane (along with three UV-C baths), the water is ready to drink.
Needing only about 35 percent humidity to work effectively, the water condenser is an elegant solution for home or office water needs. It's capable of producing up to 8 gallons of water per day and is a viable alternative to the traditional methods of getting water into your drinking glass. For those who wish to completely sever the line and go off the grid, a solar option is available, creating the opportunity for owners to harvest water directly from the air, with no pipes or electrical outlets needed.

Oysters natures Water Filter
A South Bronx community group plans to reseed the waterway with oysters and mussels and, in the process, revive the polluted waterway, which separates the Bronx from Randalls Island.The group – Friends of Brook Park – is waiting for word on a $50,000 grant from the United States Fish and Wildlife Service. "This would expose more people to the wonder of our waterways," said Harry Bubbins, who runs the Mott Haven group.
The oysters won't be fit for human consumption, but could help clean the narrow Bronx Kill, which has been devastated by dumping, sewage and landfill.Because the crusty bivalves are filter feeders – sucking in water and slurping algae and plankton from it – a square foot of oysters can filter 2,000 gallons of water per day.They also form reefs, which shelter fish, crabs and shrimp – more than 70 animal species all together, said Paul Mankiewicz of the Gaia Institute on City Island.
A century ago, oysters were so common that street stands sold them on the half-shell. But overharvesting, toxic waste and disease hit the mollusks hard. Bubbins said his group was inspired by a Bronx River restoration project.
Six years ago, the Bronx River Alliance and the city Parks Department set out to help a small colony of Bronx River oysters near Soundview Park. Like the Bronx Kill, the Bronx River had been ravaged by dumping and neglect.
In 2007 and 2008, volunteers used Long Island clamshells to build a reef for the oysters and gathered baby oysters from the water to boost the colony. In the Bronx Kill, Mankiewicz and Friends of Brook Park will install reef-like ropes made from recycled plastic, then reseed it with baby oysters.
Friends of Brook Park chose the Bronx Kill not only because it borders Mott Haven but also because the waterway is tranquil and too small for motorboat traffic. It would take an enormous oyster colony to rid the larger Bronx River of gunk, but a mollusk-powered Bronx Kill cleanup is doable, said Mankiewicz. Friends of Brook Park plans to work in the Bronx Kill near Lincoln Ave., but could also plant oysters near Mill Pond Park in the Harlem River.

"CGI realizes that dirty water is the mother of all global health challenge. They realize it is solvable," -John Oldfield, Vice President of Water Advocates
Water Advocates is a Washington-based group that lobbies for more attention to water-related health issues. Along with many other clean water initiatives, it's the first US based non-profit organization committed to escalating American support/rally for worldwide access to safe and inexpensive drinking water. Along with Doug Band, President Clinton and other various members of the Clinton Global Initiative, John Oldfield met in New York back in 2009 to discuss this epic global health challenge. But what exactly is being done today? And how does the recent havoc in the Gulf of Mexico affecting neighboring states?
Prior to the Clean Water Act of 1985, the US didn't have any clearly established guidelines for the release of toxins into lakes, rivers, etc… As we can see from perfect examples of disregard and carelessness like the progressive pollution of Onondaga Lake in Syracuse, NY, this brought about excessive pollution and pandemonium for anybody living in the vicinity. Known as one of the most polluted lakes in the US, Onondaga Lake suffered from exposure to industrial dumping and sewage contamination, much of what we still see to this day. It's clear that we're the ones responsible here; therefore we have no choice but to redeem our mistakes of yesterday by exploring new means in which to restore and preserve out water.
In most recent news, the Gulf Oil Spill has undoubtedly left a huge dent in progress, especially financially. Reports in excess of 10 billion dollars on the coast of Florida definitely support this claim. Pictures and videos continue to surface, displaying raw images of sea creatures and wildlife covered in oil. It's hard to imagine many of the surrounding ecosystems could survive in such a polluted habitat. With groups like the CGI, and Water Advocates, we have hope; but there's a lot yet to be done. Arguably, it isn't always human error – some global bodies of water are destroyed and contaminated by natural disasters. Whether or not we're responsible is an entirely different issue, but what's important is that we delve into the discovery of solutions to improve our future drinking supply.
Aside from Water Advocates, there a multitude of lobbying groups for the creation and distribution of clean and affordable water. Here are examples of a few:
And this is just a handful of action-oriented organizations ready to make a change. Some are activists, looking for petitions and/or donations to a worthy cause, while others are actually looking into domestic water purification system and plan to distribute such items in the near future. CEO of Brita claims ""The initiative is part of BRITA's corporate culture", "Because we are the leading global brand on the water filtration market we consider ourselves responsible for drinking water projects throughout the world. We want to ensure that people all over the world gain access to this vital resource." Brita is actually one of the few that provides whole-house water purification internationally.
Oldfield is correct in his statement back in 2009; its clear there this is one of the most prevalent issues of 2010, and will continue to capture more eyes as the problem worsens. At this, it's important again that we remember to support this cause by visiting the above sites to find out more about what we can do as individuals. Congruently, be sure to use your own eco-conscience mind to conserver and sustain! This means turning the sink off while you brush your teeth, or spending less time in the shower!

researchers found viruses and bacteria in East Tennessee drinking water before it was treated, a finding that may be a warning for untreated home wells.
Researchers at the University of Tennessee in Knoxville linked the contamination of the community water sources' limestone — karst — aquifers to human feces.
"Karst aquifers have long been recognized as having high susceptibility to fecal contamination because they have features, such as sinkholes and caverns, which act as pathways for rapid flow and transport of contaminants," Larry McKay said in a statement.
The study, published online in advance of print in a special edition of the journal Pathogens and Fecal Indicators in Ground Water, pointed out all eight of the sampled wells and springs were used for public water supply — water that is treated before distribution so the contamination in the study represented no direct risk to consumers.
However, the researchers say the results point to the health hazard potential of non-treated water.
"The real concern is for the numerous small non-community water systems and household wells, where local residents typically drink groundwater that hasn't been filtered or disinfected," McKay said. "It's likely that many of these residents are being exposed to waterborne fecal contamination, both bacterial and viral, but it isn't clear how big a health risk this represents. Local and regional research is needed to assess the health impacts."
Fecal contamination of the water may create no symptoms in some, while others may become seriously ill or even die, McKay noted.
One of the fastest growing water treatment technologies is uv water treatment. The water treatment industry uses a high-powered form of UV light called UV-C or “germicidal UV” to disinfect water. UV water disinfection performance is tied to the first laws of Photochemistry where only the light that is absorbed by a molecule can be effective at producing a photochemical change in the molecule. What this means is that in order for UV Water Treatment systems to work the light must be absorbed by the organism(s) in the water. Then the UV light causes damage to the DNA and RNA structure preventing it form being able to replicate itself. UV Water treatment systems are effective in destroying 99.99% of harmful microorganisms, including E. coli, Cryptosporidium, and Giardia.
