Walk For Water Ends

Walk for water charity cut short after 5,000 miles

The Gazette gives its highly coveted Hero Award to Amy Russell who walked 500o miles for a very good cause.  Below is the Independent’s account of her adventure.

After 5,000 miles and 18 months, Amy Russell is done walking.

The 24-year-old Manchester native and founder of the charity Walking4Water has ended her trek through Africa, six months and 2,000 miles earlier than planned.

Health problems and political unrest in her planned destination of Egypt caused her and walking partner Aaron Tharp to stop their walk, she said. They plan to fly home on Sunday.

Amy Russell at a watering hole in Mozambique in August of 2012. She walked on for another year after the photo was taken.

“I guess `officially’ we ended in Negele, Ethiopia,” she said via Facebook chat from Addis Ababa, the Ethiopian capital. “Random town … but the point where everything plus people throwing rocks at us every day just, where we decided to be done.”

Russell and Tharp, 26, of Trenton, Ohio, were the last two walkers standing from a journey that was supposed to include about 10 people.

It was designed to call attention to the lack of access to clean water in developing countries. The walk has raised about $10,000 for charity: water, a New York-based group that funds drinking water projects in developing countries.

Most of the other would-be walkers backed out before Russell’s journey began in South Africa in February 2012. A third member of the team, 25-year-old Marty Yoder of Elkhart, Ind., who had been driving the support vehicle, went home with health problems when the team was in Mozambique.

That left Russell and Tharp with their shoes and backpacks. They camped or stayed with missionaries or local families, traveling north through South Africa, Mozambique, Malawi, Tanzania, Kenya and Ethiopia. Russell went through seven pairs of shoes and lost about 40 pounds.

“The biggest challenge was probably just living in constant instability, we never stayed in one place very long,” Russell said. “So every day, we had to find food, had to find water, had to find a place to stay. Always dealing with a language barrier, always changing circumstances. Dealing with that mentally was probably the hardest.”

They had physical problems as well. Russell contracted malaria in Mozambique. They both got sick a number of times from drinking brackish water, and Tharp developed knee problems, Russell said. They also spent one night in Kenya huddled in a tent with a machete after noticing lions in nearby bushes.

Russell called it the most terrifying experience of her life.

“Throughout the remainder of the night, we heard yet another lion, another elephant, a two-minute lion-elephant showdown, and a couple hyenas,” Tharp wrote on his blog. “Morning never looked so beautiful!”

But it was the people that Russell said will leave a lasting impact on her.

She recalled a day she spent in a Kenyan village, going with other women and children to gather water from a hole that was a 15-minute walk away.

“From this `puddle’, maybe you could call it a small pond, we filled the jerry-cans, and walked back with them,” she said. “This water, murkier than potato soup, was what they drank directly from, without any fears or qualms.”

Russell is disappointed she wasn’t able to walk all 7,000 miles, but she’s proud she made it as far as she did.

“Instead of transforming everyone else’s life (I’m not sure I made a huge impact for others), it seems my life has been the one transformed in the process,” she said.

Russell hasn’t decided what she will do next. She will begin looking for a job and is considering graduate school.

For now, she just wants to be home, perhaps with a pizza.

“I definitely plan on doing talks, sharing the experience if people are interested,” she said. “Not sure writing a book is a good idea, but haven’t eliminated the option completely. NO MORE WALKING lol.”

  UV for Chlorine/Chloramine Reduction

Gazette’s Introductory Note.  The following short article from UVSciences.com gives a very general view of some alternative uses of ultraviolet in water treatment. UV is widely accepted as a method of water disinfection, but it is not so widely known as a treatment for TOC  (Total Organic Carbon) and the reduction of chlorine and chloramine.  The article does not explain that these special uses require special equipment and the regular 254 nanometer low pressure lamps that are used for destruction of bacteria and viruses cannot simply be applied to the treatment of  TOC or chlorine/chloramine.  Each of these requires specific wave lengths and chloramine reduction is done with a medium pressure lamp.  At present chloramine reduction with UV is mainly used for swimming pools, but other uses are being developed.–Gene Franks.

Chlorine and chloramine are used extensively for water disinfection.  These compounds, and related byproducts, such as trihalomethanes (THM’s), are often present in water supplies. These compounds must frequently be removed because they are potential health hazards, and they may affect the taste of consumable products, such as flavored beverages and bottled water. Removal is also necessary because chlorine and chloramine based compounds can significantly increase the operational/maintenance costs for purification equipment, such as ion-exchange beds and reverse osmosis (RO) membranes, all used for ultrapure water processing.

UV is becoming more popular for destroying chlorine/chloramine compounds as the performance of UV lamps improves and the costs associated with traditional methods of removal become prohibitive. The mechanism used by UV to destroy chlorine/chloramine compounds is dissociation. The ultraviolet energy “breaks” the molecular bonds of the compounds reducing them to their basic elements. These basic elements will either combine with others to form benign compounds, or they can be subsequently removed in a downstream purification process.

Traditional methods for removing chlorine/chloramine are Granular Activated Carbon (GAC) filter beds, or chemical injection using sodium metabisulfite. Sodium metabisulfite can introduce undesirable byproducts into the water supply and it can create favorable conditions for microbial growth in RO membranes downstream. Sodium metabisulfite is also a potential health hazard that requires protected storage and careful handling.

Above, a very basic UV system. The quartz sleeve, lamp inside, inserts into the stainless treatment chamber. The simple control system provides both visual and audible warning of UV lamp failure. The system comes in 2, 6, 8, and 12 gpm versions. The lamps provide strong UV dosage (30 mj/cm2 at the end of the lamp’s life) that is certified by independent testing (BioVir). Very easy to install, the unit wall mounts with two simple clips.

Activated carbon beds used for chlorine/chloramine removal are susceptible to microbial proliferation, and they are vulnerable to “break-through”. As a result, it is necessary to inspect, clean, and replace activated carbon beds regularly, which requires costly downtime on manufacturing lines.

Case studies have shown that UV treatment prior to activated carbon beds and reverse osmosis membranes will reduce overall operating costs by increasing the time between cleaning cycles, and extending the life of both GAC beds and RO membranes. Ultraviolet treatment also provides additional benefits in the form of disinfection and TOC reduction, without affecting taste and without the creation of difficult to remove residuals.
