Related QuestionsWhat is Perchlorate?
Frequently Asked Questions: PerchlorateAmmonium perchlorate (NH4ClO4) is an inorganic chemical widely used as an oxidizer in solid propellants for rockets, missiles, fireworks and explosives. Perchlorate may thus be found in surface and ground waters around military operations, defense contracting, manufacturing facilities, and areas where blasting agents have been used. Perchlorate may also be generated in small amounts within existing water treatment processes.

What Are The Health Effects Of Perchlorate?
Frequently Asked Questions: Perchloratesufficient doses, perchlorate disrupts normal function of the thyroid gland. It interferes with iodide transport into the thyroid gland, decreasing the availability of iodide needed for the synthesis of thyroid hormones, which are essential for metabolism and normal growth and development. The impacts of disrupting thyroid hormone synthesis are greatest on pregnant women and their developing fetuses, infants, children, and individuals who have low levels of thyroid hormones.
Related QuestionsWhat Perchlorate Standards Are Being Set By MassDEP?
Frequently Asked Questions: PerchlorateMassDEP is promulgating a drinking water standard or Maximum Contaminant Level (MCL) of 2 ppb. This is the first drinking water standard for perchlorate in the nation. Perchlorate soil and groundwater standards for hazardous waste site cleanup under the Massachusetts Contingency Plan or MCP (MGL Chapter 21E) are also being established, along with the adoption of a reference dose (RfD) of 7 x 10-5 mg/kg-day to be used for site-specific risk assessments.
Related QuestionsWhat is the Basis of MassDEP's Perchlorate Standards?
Frequently Asked Questions: PerchlorateMassDEP's perchlorate MCL is based on an assessment of the health risks of perchlorate using a thorough analysis of perchlorate's toxicity, including review of the NAS perchlorate report, by MassDEP toxicologists with extensive input from a science advisory committee comprised of academic scientists and public health professionals from other agencies. Other factors were then taken into account in selecting the final drinking water standard.
Related QuestionsWhy Did MassDEP Choose To Address Perchlorate Risk?

Frequently Asked Questions: PerchlorateIt is important to note that the US EPA has not yet set a standard for perchlorate and will likely not do so for several years. US EPA's 24.5 ppb Drinking Water Equivalent Level (DWEL) value is not a final standard but is an intermediate value used to set a final standard. It does not account for any other source of exposure. Final drinking water standards, including our own, consider other sources of exposure, including those from foods, which have been documented to occur.
Related QuestionsWhy Did MassDEP Select a Lower Reference Dose for Perchlorate than US EPA?
Frequently Asked Questions: PerchlorateThe reference dose is the total daily dose of a chemical, from all sources, that is anticipated to be without risk of adverse effect.
