What can Anaheim do to remove perchlorate?
A. Perchlorate can be removed from groundwater by advanced treatment systems. Staff from Anaheim has met with consultants to estimate what this type of treatment would cost. Treatment of perchlorate could cost up to $50 million and lead to an increase in water rates by 15 to 25 percent. Given that Anaheim’s perchlorate levels are below the PHG that protect the most sensitive persons, we do not believe that it is prudent to invest in treatment systems to remove the low levels of perchlorate from our water supply. However, if perchlorate levels were to unexpectedly increase, your Water Utility has already worked with an engineering consultant to identify the treatment systems needed to remove perchlorate. Anaheim is committed to protecting water quality and stands ready to implement additional treatment if needed.
