Coleman, South Dakota goes for the gold (free money)

$2,195,256 in state funding, includes:

  • $1,574,248 Clean Water State Revolving Fund loan for sewer line replacement, with $356,500 of the loan in principal forgiveness (read, free money)
  • $182,000 Drinking Water State Revolving Fund loan for water meter replacement
  • 439,008 Drinking Water State Revolving Fund loan for water main replacement.

California to go after hydraulic fracturing….

The State of California is asking oil companies to tell the state where fracturing is being done….in the name of protecting drinking water, of course.

Existing laws protect California’s drinking water. The state environmental activists need something to create more worry and attention?

High serum fluoride affects children’s IQ?

Xiang, Q., Liang, Y., Chen, B., and L. Chen. Research report: Analysis of Children’s Serum Fluoride Levels in Relation to Intelligence Scores in a High and Low Fluoride Water Village in China. Fluoride 44(4)191–194, October-December 2011.

SUMMARY: As part of a 2002-2003 investigation on the effects of high fluoride drinking water on IQ scores of children, serum fluoride (F) levels in the children were subjected to further study. Among the new findings, although IQ scores of boys and girls differed in the seven IQ level categories, there were no overall gender differences (boy/girl ratio 1.220 vs. 1.214 in the high and low F villages, respectively). However, the mean IQ was significantly higher and there were fewer children with an IQ less than 80 in the two quartiles with a serum fluoride level of less than 0.05 mg F/L. Analysis of the overall relationship between IQ scores and serum F levels indicates there may be no serum F level below which adverse effects on IQ might not be present.

Multi-state salmonella outbreak caused by contaminated food

Drinking water is typically blamed falsely for illness, but contaminated food causes millions of illnesses each year…….Salmonella in particular.

Are carbonate ions more easily dissolved in human tooth enamel if fluoride present?

Enamel was analyzed using micro-Raman spectroscopy….

Zavala-Alonso, V., Loyola-Rodriquez, J.P., Terrones, H., Patino-Marin, N., Martinez-Castanon, G.A., and K. Anusavice. Analysis of the molecular structure of human enamel with fluorosis using micro-Raman spectroscopy. J Oral Sci. 2012;54(1):93-8.

The aim of this study was to analyze the molecular structure of enamel with fluorosis using micro-Raman spectroscopy and compare it with that of healthy enamel. Eighty extracted human molars were classified into four fluorosis groups according to the Thylstrup-Fejerskov Index (TFI) [TFI: 0, Healthy enamel; 1-3, mild; 4-5, moderate; 6-9, severe fluorosis]. All samples were analyzed by micro-Raman spectroscopy. The integral areas of ν(1) (960 cm(-1)) phosphate peak as well as B-type carbonate peak (1070 cm(-1)) were obtained to analyze structural differences among the specimens. Although the differences were not statistically significant (P > 0.05), the mean of integral areas of ν(1) phosphate peak among groups indicated greater mineralization in the severe fluorosis group. However, there were statistically significant differences in the intensities, and the integral areas of B-type carbonate peak among groups (P < 0.05). Therefore, mineralization of the carbonate peak at 1070 cm(-1) decreased significantly in fluorotic groups, suggesting that carbonate ions are easily dissolved in the presence of fluoride. Although structurally fluorotic teeth are not more susceptible to dental caries, serious alteration in its surface topography may cause retention of bacterial plaque and formation of enamel caries. Micro-Raman spectroscopy is a useful tool for analyzing the molecular structure of healthy and fluorotic human enamel.

 

Lake Erie blue-green algae plume persists

Cyanobacteria in algae blooms can release toxins that can cause liver problems, gastrointestinal illness and headaches…Swimmers could become ill if they swim in an algae bloom and accidentally swallow some of the water.
