Blue-green algae is thriving in Oklahoma’s reservoirs this summer due to the combined factors of high heat, drought, and the resulting stagnant water, reports News9.com. Although the presence of thealgae, which can be toxic to humans and animals, prevents people from swimming in the reservoirs around Oklahoma City, News9.com advises that water treatment officials say drinking water is safe. Water treatment plants use a process that eliminates the algae from the public drinking water.
A spill of a highly corrosive chemical, Hydrofluorosilicic acid, at a water facility in Illinois literally burned through the concrete. Interesting fact: this chemical is directly added to drinking water as fluoride.
In 1999, the Department of Health commissioned CRD to conduct a systematic review into the efficacy and safety of the fluoridation of drinking water. The review specifically looked at the effects on dental caries/decay, social inequalities and any harmful effects. The review was published on the CRD Fluoridation Review website and in the BMJ in October 2000.
