Polyglutamic acid (PGA) is an amino acid formed by bacterial fermentation. Water-soluble, biodegradable and edible, PGA is responsible for the stickiness of natto, a Japanese dish made from fermented soybeans. Added to water, it acts as what is called a flocculant, a chemical that promotes the separation of solid particles from a liquid. It causes the particles to form loose aggregations, or `floc,' which then settle to the bottom.

Powering the Water of Life
AAR Japan brings sustainable water to a vulnerable region

In August of 2011 AAR Japan decided to initiate emergency humanitarian interventions among affected populations in the Garissa region. A rapid decline in security a few months later forced the staff to relocate to the city of Kitui, where they began constructing a 17-kilometer pipeline to bring water to four different `water kiosks.' Overcoming project delays and leaking pipe joints, Igarashi says he and his staff were "overjoyed when the first trickle of water sputtered, then suddenly started flowing out from the tap."
