Colton (CA) hospital serves bottled water after contamination threat

A threat of drinking water contamination at Arrowhead Medical Center was responded to immediately by hospital officials. Bottled water was served and water testing conducted…..click here….

Water resources a continuing concern for Arab League

The availability of water resources or lack thereof have shaped the history of mankind from the earliest days.  Why should we expect it to be different today? (An no, it is not the result of atmospheric CO2 or some other global warmist conspiracy theory.)

Healthy teeth are possible without fluoridation of drinking water

Here is an interesting article on Hightstown, New Jersey……which stopped water fluoridation 18 months ago….but customers are just now finding out about it.

Click here…..Contrary to the claim in the article, addition of fluoride to drinking water is not a “fluoride treatment” like you would get at the dentist.  In fact, it is not necessary at all to add fluoride to drinking water in order for children to have healthy teeth if they take care of themselves.

Source of radioactive iodine in drinking water tied to thyroid patients

One thyroid patient receiving I-131 treatment could excrete enough of the substance to be measurable in a watershed…..but below concentrations of concern.

University bans on bottled water restrict student freedom of choice?

Looks like bottled water manufacturer’s are now complaining of choice restrictions on university campuses…….click here……the argument, of course, is that banning of plastic bottled water is necessary to save the earth in the name of sustainability…..hardly.  When tap water is contaminated anywhere in the world (including the US), guess what people drink?….plastic bottled water…..gee, maybe it is not so bad afterall….

Data show no acceleration of Australia sea level rise

Boretti, A. Is there any support in the long term tide gauge data to the claims that parts of Sydney will be swamped by rising sea levels? Coastal Engineering, Volume 64, June 2012, Pages 161–167  http://dx.doi.org/10.1016/j.coastaleng.2012.01.006

Abstract: The government of Australia is supporting the statement that sea levels are rising faster than ever before as a result of increased carbon dioxide emissions. Consequent to this, low-lying coastal areas, where the majority of Australians are concentrated, have been declared at risk of sea level inundations. Maps with 0.5, 0.8 and 1.1 m sea level rise have been proposed for Sydney, the major Australian city. However, long term tide gauges, recording sea levels worldwide, as well as along the coastline of Australia, and within the bay of Sydney, do not show any sign of accelerating sea level rises at present time.

“DALY”-ing around with fluoridation computer models

This Australia study uses a theoretical measure of health effects called the DALY, or disability adjusted life-years, which is not generally accepted. Computer simulations like this are subject to the same limits as any computer model (garbage in, garbage out). In this particular case, it looks as if the expected adverse effects are not considered at all…. 

Cobiac, L.J., and T. Vos. Cost-effectiveness of extending the coverage of water supply fluoridation for the prevention of dental caries in Australia. Community Dent Oral Epidemiol. 2012 Mar 27. doi: 10.1111/j.1600-0528.2012.00684.x.

OBJECTIVE: Fluoride was first added to the Australian water supply in 1953, and by 2003, 69% of Australia’s population was receiving the minimum recommended dose. Extending coverage of fluoridation to all remaining communities of at least 1000 people is a key strategy of Australia’s National Oral Health Plan 2004-2013. We evaluate the cost-effectiveness of this strategy from an Australian health sector perspective.

METHODS: Health gains from the prevention of caries in the Australian population are modelled over the average 15-year lifespan of a treatment plant. Taking capital and on-going operational costs of fluoridation into account, as well as costs of caries treatment, we determine the dollars per disability-adjusted life years (DALY) averted from extending coverage of fluoridation to all large (≥1000 people) and small (<1000 people) communities in Australia.

RESULTS: Extending coverage of fluoridation to all communities of at least 1000 people will lead to improved population health (3700 DALYs, 95% uncertainty interval: 2200-5700 DALYs), with a dominant cost-effectiveness ratio and 100% probability of cost-savings. Extending coverage to smaller communities leads to 60% more health gains, but is not cost-effective, with a median cost-effectiveness ratio of A$92 000/DALY and only 10% probability of being under a cost-effectiveness threshold of A$50 000/DALY.

CONCLUSIONS: Extension of fluoridation coverage under the National Oral Health Plan is highly recommended, but given the substantial dental health disparities and inequalities in access to dental care that currently exist for more regional and remote communities, there may be good justification for extending coverage to include all Australians, regardless of where they live, despite less favourable cost-effectiveness.
