Sodium and Total Dissolved Solids Increase in MWD Water After Fluoridation

Lines are computed moving averages and increase progressively after 2007 when industrial sodium fluorosilicate injections began to treat tooth decay. Every ton of industrial waste fluosilicic acid requires 1/2 ton of sodium from sodium hydroxide Drano to maintain pH at 8.1 (two H+ ions from H2SiF6 requires two sodium ions).

Sodium at 116 ppm decreases crop yields and affects vegetable and fruit quality. Avocado production in Southern California is already down due to current sodium levels (North County Times, 2010). Sodium is released into the Colorado River by scores of industries lining the river. The EPA salt abatement program limits releases to one ton daily per site, but an exception has been made for Shell Oil at 2,000 tons salt daily at one facility.

Metropolitan Water District Los Angeles entered the industrial salt injection problem in 2007, with 0.1 tons daily sodium added at Lake Skinner alone, to neutralize fluosilicic acid to attempt to treat tooth decay that instead causes fluorosis. The EPA secondary standard for TDS (500 ppm) is exceeded but is not enforced–plants can tolerate natural TDS from 800-1000 ppm. No EPA standards have been developed by EPA for sodium since fresh water has historically been low in sodium. Sodium in blood is 3,000 ppm but is 0-10 ppm in pristine fresh drinking water. Vallecitos Water District raises no objections or questions to MWD on the injections and has ignored public testimony since 2006 opposing the ingestion of the non-FDA-approved fluoride water drug.
