Automated Chlorination Needed in Low-Income Urban Communities, Bangladesh

Pickering AJ, Crider Y, Amin N, Bauza V, Unicomb L, Davis J, Luby SP. Differences in Field Effectiveness and Adoption between a Novel Automated Chlorination System and Household Manual Chlorination of Drinking Water in Dhaka, Bangladesh: A Randomized Controlled Trial. PLoS One. 2015 Mar 3;10(3):e0118397. doi: 10.1371/journal.pone.0118397.

The number of people served by networked systems that supply intermittent and contaminated drinking water is increasing. In these settings, centralized water treatment is ineffective, while household-level water treatment technologies have not been brought to scale. This study compares a novel low-cost technology designed to passively (automatically) dispense chlorine at shared handpumps with a household-level intervention providing water disinfection tablets (Aquatab), safe water storage containers, and behavior promotion. Twenty compounds were enrolled in Dhaka, Bangladesh, and randomly assigned to one of three groups: passive chlorinator, Aquatabs, or control. Over a 10-month intervention period, the mean percentage of households whose stored drinking water had detectable total chlorine was 75% in compounds with access to the passive chlorinator, 72% in compounds receiving Aquatabs, and 6% in control compounds. Both interventions also significantly improved microbial water quality. Aquatabs usage fell by 50% after behavioral promotion visits concluded, suggesting intensive promotion is necessary for sustained uptake. The study findings suggest high potential for an automated decentralized water treatment system to increase consistent access to clean water in low-income urban communities.

National Energy Policy Does Not Include “Burning the Constitution”

We’ve known this. It’s about time someone said the obvious….

” “EPA possesses only the authority granted to it by Congress,” Tribe told lawmakers in a hearing Tuesday. “Its gambit here raises serious questions under the separation of powers… because EPA is attempting to exercise lawmaking power that belongs to Congress and judicial power that belongs to the federal courts.”

“Burning the Constitution should not become part of our national energy policy,” Tribe added. ” here for more
