The Importance of Fluoride

You brush your teeth with it, drink water containing it, even use it as a medicine; but do you really know the risk of too much fluoride. Fluoride is a substance used to help aid in the prevention of tooth decay. However, the use of fluoride in excess can result in bone fractures and pits in tooth enamel. In the United States, fluoride levels in drinking water are monitored by the EPA, which enforces a maximum contaminant level (MCL) of 4.0 ppm.

What Happened To Toledo’s Drinking Water?

In a recent article from Water Quality & Health online, it discusses the reasoning behind 500,000 citizens without clean tap water. The cause of this is due to microcystins. “Microcystins are a large class of naturally occurring toxic chemical substances produced by waterborne bacteria known as Microcystis, also called ‘blue-green algae’ or ‘cyanobacteria.” This can be caused by nutrient-rich wastewater and agricultural runoff into water bodies creating microcystis blooms. Microcystis blooms thrive with sufficient levels- of phosphorus and nitrogen as well as temperatures in the 5 to 30 degrees C range and a pH ranging from 6-9. “Microcystin (the toxin) is released when the bacteria die and their cells break open.”

From Toilet to Tap Water

A recent article found on Science Daily discusses the current drought situation in Wichita, TX.  Due to the effects of a 3 year drought Wichita is struggling to find water resources that they can tap into to effectively cover the Wichita population.  However, the town is looking into a rather controversial solution turning toilet water to tap water.

Fluoride in Water

Fluoride is a naturally occurring element that helps to prevent tooth decay.  An article found on the American Water Works Association website discusses the Fluoride in drinking water, health, and safety.  Since adding fluoride to the water in 1945 child tooth decay has reduced by 20-40%.

“Fluoride’s effect is topical. It keeps the tooth enamel strong by preventing the loss of important minerals.”  Fluoride in drinking water is endorsed by American Dental Association, the American Medical Association, and the US Public Health Service.”

Arsenic and Drinking Water

The availability of clean, safe drinking water is a common issue the world over.  Despite living on a planet with water covering 71% of its surface, clean drinking water is a limited resource.

How difficult is it to get access to clean water?

–          Over 96 percent, is saline water in the oceans1
–          Less than 1% of the planets remaining water is freshwater2
–          According to “every 21 seconds, a child dies from a water-related illness”.

Science Daily recently published an article titled “Is Enough Being Done to Make Drinking Water Safe?”.  The article discusses the specific threat of arsenic in drinking water supplies.

Nitrates and Groundwater

A recent article in WaterWorld describes how nitrates found in groundwater may take decades to get filtered out.  USGS researchers discovered that groundwater nitrate levels were above expected levels, despite the reduction of nitrogen-based fertilizer in the areas tested.

“In this study, USGS scientists closely examined surface and ground waters at seven study sites from across the nation to determine the portion of stream nitrate derived from groundwater… The slow release of groundwater nitrate to streams may also affect the water quality of large rivers. For example, increases in nitrate concentrations during low and moderate flows in large rivers in the Mississippi River Basin have been observed to be greater than or comparable to increases in nitrate concentrations during high flows.”

Nitrate is a naturally occurring form of nitrogen found in soil. It is also often found in fertilizer, since most crop plants require high levels of nitrates to produce high yields. Issues can arise when water runoff carries excess nitrates from agricultural and urban sources
