New tool provides gauge for freshwater health
The most cost-effective way to keep fresh water clean for human use? Nature itself. Forests, rivers and wetlands filter out contaminants, store excess water, and in some cases even drive rainfall, so maintaining the health of those ecosystems — typically far upstream from population centers — is critical.
[…]The FHI has been tested in two locations: the Sekong, Sesan, and Srepok (“3S”) Basin of the Lower Mekong River in Laos, Vietnam and Cambodia; and the Dongjiang Basin of the Pearl River in China.
