Providing clean water, keeping water clean: an integrated approach

International Journal of Environmental Health Research, 2003
Millions of people, most of whom are children in developing countries, die of basic hygiene-related diseases every year. Interventions in hygiene, sanitation and water supply have been shown to control disease burden. Universal access to improved water sources and basic sanitation remains elusive but is an important long-term goal.

Magnetic water cleaning

Nachrichten aus der Chemie, 2021
AbstractHazardous water pollution caused by pure or chemically refined hydrocarbons – e.g., crude oil, nano‐ and microplastics, or herbicides – can be removed by rust. Nanoscience combined with chemical recognition motifs on surfaces enables an efficient and sustainable technique.

Large portion of USA streams lose protection with new interpretation of Clean Water Act

Freshwater Science, 2021
The recently promulgated Navigable Waters Protection Rule eliminates federal protection for ephemeral streams previously covered by the Clean Water Act in the USA, but the regulatory agencies assert that map limitations preclude any quantification of the
