A photo in the Pasadena Star News shoes city officials and representatives of JPL toasting with “perchlorate free water” to the opening of the $8.5 million Monk Hill Water Treatment Plant in the Upper Arroyo Seco.
What wasn’t shown is that the standard used to measure whether the perchlorate in groundwater supplies is harmful is based on a fallacious assumption that groundwater is undiluted and not mixed with imported water supplies from the MWD or other well water that is uncontaminated. Once properly diluted, perchlorate at 6 parts per billion is not considered harmul to the unborn, small children and pregnant mothers who may not get enough iodine in the diet for normal intellectual development. The solution to pollution is dilution.
Perchlorate is an endocrine blocker that can block the body’s absorption of iodine. Nor are photos shown of a box of iodized salt. Iodine as a supplement in table salt makes up for any iodine deficiency in the human diet or drinking water and costs way less than $8.5 million.
Perchorate cleanup treatment plants are mostly technological symbolism used by two-faced politicians to stay elected and provide useless jobs that do not improve the health of the community. There never has been a study of the health improvements from removing perchlorate from drinking water – because there probably aren’t any health benefits from doing so in most cases.
