Yang GC; Yen CH; Wang CL. Monitoring and removal of residual phthalate esters and pharmaceuticals in the drinking water of Kaohsiung City, Taiwan. Journal Of Hazardous Materials 2014 Jul 30; Vol. 277, pp. 53-61.
This study monitored the occurrence and removal efficiencies of 8 phthalate esters (PAEs) and 13 pharmaceuticals present in the drinking water of Kaohsiung City, Taiwan. The simultaneous electrocoagulation and electrofiltration (EC/EF) process was used to remove the contaminants. To this end, a monitoring program was conducted and a novel laboratory-prepared tubular carbon nanofiber/carbon/alumina composite membrane (TCCACM) was incorporated into the EC/EF treatment module (collectively designated as “TCCACM-EC/EF treatment module”) to remove the above mentioned compounds from water samples. The monitoring results showed that the concentrations of PAEs were lower in water samples from drinking fountains as compared with tap water samples. No significant differences were found between the concentrations of pharmaceuticals in the two types of water samples. Under optimal operating conditions, the TCCACM-EC/EF treatment module yielded the lowest residual concentrations, ranging from not detected (ND) to 52ng/L for PAEs and pharmaceuticals of concern in the tap water samples. Moreover, the performance of the TCCACM-EC/EF treatment module is comparable with a series of treatment units employed for the drinking fountain water treatment system. The relevant removal mechanisms involved in the TCCACM-EC/EF treatment module were also discussed in this work.

The protest (here) against the recent religious freedom law in Indiana is a made-up issue. Such laws are needed to prevent discrimination against Christians and people of other faiths. Every state should have such a law.

Hypothyroidism is more prevalent in areas with fluoridated drinking water. Nursing Standard (Royal College of Nursing (Great Britain) 2015 Mar 25;29(30):15. doi: 10.7748/ns.29.30.15.s19.
UK researchers have called for a rethink on adding fluoride to the water supply in England after a study showed a significant link between water fluoridation and higher rates of hypothyroidism.

[Tap water as a dietary source of exposure to fluoride in tenerife; risk assessment]. Nutrición Hospitalaria 2015 Apr 1;31(4):1787-94. doi: 10.3305/nh.2015.31.4.8564.[Spanish]
INTRODUCTION: drinking water is the main source of fluoride exposure for the population. According to the Spanish Law RD 140/2003, the fluoride content in drinking water should not exceed the parametric value of 1.5 mg/L. Historically, certain drinking waters in the island of Tenerife have exceeded this value due to the geological/volcanic characteristics of the Canary Islands. Fluoride (F) plays an important role in the prevention of dental caries (tooth decay). However, long exposure to concentrations above 1.5 mg/L in drinking water can cause disorders such as dental fluorosis.
OBJECTIVES: To determine the amount of fluoride in the tap waters of the 11 municipalities in the north of the island of Tenerife that, at the time of the study, exceeded the parametric value for fluoride set by the Spanish legislation and to toxicologically estimate and evaluate the fluoride daily intakes from water considering the RDI (Recommended Daily Intake) established in Spain for different population groups.
METHOD: 44 samples of tap water collected in the 11 municipalities in the study were analyzed using the fluoride potentiometric determination with an ion selective electrode.
RESULTS: 9 of the 11 municipalities presented mean fluoride concentrations in their tap water that exceeded the parametric value set by the Spanish legislation (1.5 mg/L). Considering an average daily water consumption of 2 L, the recommended daily intake (RDI) for women (3 mg F/day) is exceeded in 9 of the 11 municipalities and the RDI for men (4 mg F/day) is exceeded in 5 of the 11 municipalities. Considering a daily water consumption of 1.5 L, the RDI for children of 2-3 years (0.7 mg/day) is clearly exceeded in all municipalities.
CONCLUSIONS: The results show the existing public health problem on the island of Tenerife and justify the tap water consumption restrictions put in force by the Public Health Authorities of the Canary Islands at the time of the study. Children are the most exposed population group to the risks of fluoride because its RDI is lower.
“Allowing an ISIS “freedom fighter” to conduct a training camp for Cornell students is “. . . like bringing in a coach, to do training on a sports team or something.“
That’s what Joseph Scaffido, Assistant Dean of Students at Cornell, said to our undercover investigator when they discussed creating a campus club focused on aiding Hamas and ISIS.”
Scaffido agreed with included sending care packages to ISIS, providing funding sources for the club, and allowing the club to bring an ISIS “freedom fighter” to campus to give a lecture.
“programs like that really do have a good place here at Cornell.“

The belief that tap water having fluoride is necessary and that somehow tap water with fluoride is better than bottled water without it is very entrenched in certain circles. Studies like this do not support any such conclusion but are conducted to attempt to convince others of that which is unjustifiable (tap water fluoridation). Tap water fluoridation is simply a sacred cow.
Horowitz AM, Kleinman DV, Child W, Maybury C. Perspectives of Maryland Adults Regarding Caries Prevention. American journal of public health. 2015 Mar 19:e1-e7.
OBJECTIVES: We obtained in-depth information from low-income parents and caregivers of young children about their knowledge and understanding of and practices related to the prevention and control of dental caries (tooth decay).
METHODS: In 2010, we conducted 4 focus groups in Maryland communities with low-income, English-speaking parents and caregivers who had at least 1 child aged 6 years or younger or who were pregnant. We developed a focus group guide based on findings of a previous statewide random telephone survey of adults with young children.
RESULTS: Most participants had limited understanding of and extensive misinformation about how to prevent dental caries. They were confused about the use of juice and its impact on their child’s teeth and had limited understanding of the use of fluorides to prevent caries. Most did not drink tap water and did not give it to their children; rather, they used bottled water.
CONCLUSIONS: These results and those of the statewide telephone survey strongly suggest the need for educational interventions designed for those with limited levels of education.
