Toxic blue-green algae bloom in the Willamette River (OR)

“State health officials confirmed the presence of toxic blue-green algae in the Willamette River and expanded the health advisory warning people and their pets to stay out of the water.” click here

Google spokesperson deceived on “climate change”

Mr. Schmidt is blinded by politics. Yes, Mr. Schmidt the climate is changing every day, week, month, year, decade, century. But this has no relationship whatsoever to climate models and speculations of the IPCC. On what basis do you make the claim that I am lying. Please tell me.

“Everyone understands climate change is occurring. And the people who oppose it are really hurting our children and our grandchildren and making the world a much worse place. And so we should not be aligned with such people. They’re just literally lying.” click here

Drinking Water Arsenic Exposure in Peru

Christine Marie George, Laura Sima, M Helena Jahuira Arias, Jana Mihalic, Lilia Z Cabrera, David Danz, William Checkleya & Robert H Gilmana. Arsenic exposure in drinking water: an unrecognized health threat in Peru. Bull World Health Organ 2014;92:565–572 doi: http://dx.doi.org/10.2471/BLT.13.128496

Objective: To assess the extent of arsenic contamination of groundwater and surface water in Peru and, to evaluate the accuracy of the Arsenic Econo-Quick™ (EQ) kit for measuring water arsenic concentrations in the field.

Methods: Water samples were collected from 151 water sources in 12 districts of Peru, and arsenic concentrations were measured in the laboratory using inductively-coupled plasma mass spectrometry. The EQ field kit was validated by comparing a subset of 139 water samples analysed by laboratory measurements and the EQ kit.

Findings: In 86% (96/111) of the groundwater samples, arsenic exceeded the 10 µg/l arsenic concentration guideline given by the World Health Organization (WHO) for drinking water. In 56% (62/111) of the samples, it exceeded the Bangladeshi threshold of 50 µg/l; the mean concentration being 54.5 µg/l (range: 0.1–93.1). In the Juliaca and Caracoto districts, in 96% (27/28) of groundwater samples arsenic was above the WHO guideline; and in water samples collected from the section of the Rímac river running through Lima, all had arsenic concentrations exceeding the WHO limit. When validated against laboratory values, the EQ kit correctly identified arsenic contamination relative to the guideline in 95% (106/111) of groundwater and in 68% (19/28) of surface water samples.

Conclusion: In several districts of Peru, drinking water shows widespread arsenic contamination, exceeding the WHO arsenic guideline. This poses a public health threat requiring further investigation and action. For groundwater samples, the EQ kit performed well relative to the WHO arsenic limit and therefore could provide a vital tool for water arsenic surveillance.

California to buy drinking water for drought-stricken residents

“The executive order provides money to buy drinking water for residents, while also directing officials to work with counties and local agencies to find solutions for the shortages. California is in the grips of its third dry year. In January, the governor declared a drought emergency.” click here
