Radionuclide and chemical concentrations in mineral waters at Saratoga Springs, New York

A project to characterize the radionuclide and chemical components in natural spring waters in the vicinity of Saratoga Springs, New York (USA) has been completed. As a result of the measured radionuclide and chemical content, eight springs were labeled as mineral waters, whereas three springs contained very low concentrations of these components. The mineral waters were highly enriched in alkaline and alkaline-earth elements, as well as chloride ions. Three isotopes of radium ((224)Ra, (226)Ra, (228)Ra) were detected in the mineral waters and reached concentrations of 1, 20, and 2 Bq/L, respectively. Overall, the (226)Ra isotope constituted about 80% of the total radioactivity measured in the water samples. Dissolved uranium concentrations in the mineral waters were very low (mean approximately 50 mBq/L).     

Can forest policy contribute to solving the CO2 problem?

The steady rise of atmospheric carbon dioxide concentration is due to the combined effects of fossil fuel burning and large scale deforestation. World-wide large scale reforestation could provide, within 15–20 years, an additional biospheric sink of the order of magnitude of the present input. Its capacity would be limited to a time span of several decades, but this time could be used to develop and deploy altenative energy sources (solar, geothermal and others) which presently are unavailable for immediate large scale use.
