Water Industry Being Mislead by “Global Warming” Propaganda

Recently articles such as this one in Water and Wastes Digest have appeared promoting the recent NOAA report and claim that 2014 was the warmest year on record. This is false (e.g. here). Indeed, much of the content of this article is biased spin. This type of reporting has been commonplace in the water industry and is simply propagandizing.

How do “climate models” account for active volcanoes?

I’ve often wondered about the ability of climate models to account for active volcanoes, of which there are 36 currently (e.g. here). There were more than 3,542 eruptions in the 20th century (more here).  How do volcanic eruptions impact global temperatures? 

Fluoride in Drinking Water; Balochistan, Pakistan

Chandio TA, Khan MN, Sarwar A. Fluoride estimation and its correlation with other physicochemical parameters in drinking water of some areas of Balochistan, Pakistan. Environmental Monitoring and Assessment. 2015 Aug;187(8):4753. doi: 10.1007/s10661-015-4753-6.

The fluoride level in drinking water is an important parameter and has to be controlled in order to prevent dental and skeletal fluorosis. The objective of this study is to assess fluoride content and other water quality parameters in the samples taken from open wells, tube wells, and karezes of Mastung, Mangochar, and Pringabad areas of Balochistan province. A total number of 96 >drinking water samples out of 150 were found unfit for human consumption. Area-wise analysis show that the samples from 39 sites from Mastung, 12 from Mangochar, and 13 from Pringabad were found in the risk of dental fluorosis of mild to severe nature. However, 12 sampling sites from Mastung, 8 from Mangochar, and 2 from Pringabad were identified as the risks of mottling and skeletal fluorosis or other bone abnormalities. The highest concentration of F(-) has been observed as 14 mg L(-1) in Mastung. Correlation analysis show that fluoride solubility in drinking water is pH dependent; and the salts of Ca(2+), Na(+), K(+), Cl(-), and SO4 (2-) contribute to attain the favorable pH for dissolution of fluoride compounds in drinking water. Principal component analysis shows that the geochemical composition of the rocks is only responsible for groundwater contamination. On the basis of the results, defloridation of the identified sampling sites and continuous monitoring of drinking water at regular basis is recommended at government level to avoid further fluorosis risks.
