A couple of years ago, I attended a Groundwater Seminar in Zanesville, Ohio. You allway's learn new words, things to do, and not to do. I learned a new word from that seminar called "Percholate". And it is found in groundwater, and at high levels can become dangerous to ones health. Tonight while watching our local TV Channel 8 from Cleveland, Ohio, it is now been found in the milk supply, dairy, organic & soy. I will post the web-site so you can watch the Video showing the results for yourself. Percholate at high levels mess's with the Hormone in women that affects the thyroid gland. And we know we give our little ones milk to ***** to be strong and healthy. And I wonder at what levels it can hurt them? For that watch the Video please! Also it has been found in food, remember the plants take in nutriants from the ground there planted in, from Apples & Oranges to Tomatoes & Lettuce and all in between, we could be at risk. I believe it gets into the groundwater from factories, construction, ******* dumping of the product. It might be something you might want to check into. I hope you find it at least informative.

Update on the Question of Perchlorate Exposure and Potential Effects on the Thyroid: Response to CDC Report of Environmental Perchlorate Exposure
December 13, 2006
The Centers for Disease Control and Prevention (CDC) has just published data on urinary perchlorate, nitrate, and thiocyanate levels that they have measured from a nationwide health survey conducted in 2001-2002 [NHANES 01-02](1). Their analysis has now been published in the journal Environmental Health Perspectives. The authors report that women with low urinary iodine spot measurement (< 100 ug/L) had lower levels of serum thyroxine and higher levels of TSH associated with higher levels of perchlorate in the *****, although these values remained within the normal range. Among the women with urinary iodine values > 100 ug/L, serum TSH, but not serum T4 values, were associated with ***** perchlorate values. In contrast, there was no association between urinary perchlorate concentration and thyroid function tests in men, irrespective of iodine excretion. We understand that further analyses of these data will be conducted and that CDC intends to replicate it in a subsequent population study.
These findings are intriguing, although several features of the study may limit the immediate application to guidelines for perchlorate exposure standards. These additional factors need to be considered in order to interpret these analyses. Serum thyroxine was measured as total thyroxine rather than as free thyroxine, the most frequently used clinical measurement and the physiologically available form of thyroxine. Thyroid autoantibodies, an important confounder in thyroid physiology, have not yet been measured. These have an especially high prevalence in women and may have contributed to the reported correlations. The presence of potentially confounding pharmaceutical and medical factors, such as estrogen use or autoimmune thyroid disease, was not used as a basis for exclusion from the analysis. Inclusion of laboratory results from multiple laboratories may need to be more carefully considered. The reason that perchlorate, but no other measured goitrogen studied, influenced thyroid function at low urinary levels of iodine is not explained. The development of further laboratory information is necessary before the implications of the findings can be understood. The issues raised are important and additional study to resolve them should be pursued.
