UCLA doctor says low levels of perchlorate pose no health threat - Posted April 26, 2004
"Jerome Hershman, an endocrinologist from the UCLA School of Medicine, said perchlorate poses no health threat to humans at the low levels found in drinking water and leaves the body within a couple days after consumption. 'To get (hypothyroidism), you'd have to probably take in an amount that is hundreds of times higher than that in drinking water,' he said."

American Thyroid Association Issues Statement on Perchlorate - Posted February 6, 2004
"Perchlorate levels in water within the interim EPA guidelines of 4-18 ppb do not appear to be associated with any significant impairment of thyroid gland function in adults. The ATA intends to continue monitoring the thyroid related health aspects of environmental exposure to perchlorate. We await the findings of the NAS Committee and will then give further consideration to how we can best advise health professionals and the community at large on this important health issue."

(March 5-6, 2002)
Watch the clip"What we are seeing is extremely conservative risk assessment practices that result in very costly treatment and remediation actions. Far too often, these risk assessment practices and findings are distorted by various interest groups who deliberately mislead and scare the public. The result is a diversion of public and private dollars into unnecessary risk management efforts and away from more immediate, real and dangerous health related programs... As detection technology improves, more resources are devoted to removing smaller and smaller amounts of elements from our drinking water, yet at a price that takes dollars away from our communities and our ability to address very real health concerns. Let us not create phantom health threats where valuable resources provide no real reduction in risk to public health."
