Why Is It Necessary For MassDEP To Set Perchlorate Standards?

Frequently Asked Questions: Perchlorate
MassDEP is establishing perchlorate standards to ensure that public health is protected and to facilitate the cleanup of perchlorate sources.

What Perchlorate Standards Are Being Set By MassDEP?

Frequently Asked Questions: Perchlorate
MassDEP 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.

What is the Basis of MassDEP's Perchlorate Standards?

Frequently Asked Questions: Perchlorate
MassDEP'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.

Will MassDEP Update its Perchlorate Standards as New Information Becomes Available in the Future?

Frequently Asked Questions: Perchlorate
It 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.

Why Did MassDEP Choose To Address Perchlorate Risk?

Frequently Asked Questions: Perchlorate
In April 2002, the Bourne Water District (BWD) asked MassDEP for guidance on perchlorate, after the compound was detected in their wells. At that time, no drinking water standard had been set by the either the U.S. Environmental Protection Agency (USEPA) or the state.

Why Did MassDEP Select a Lower Reference Dose for Perchlorate than US EPA?

Frequently Asked Questions: Perchlorate
The reference dose is the total daily dose of a chemical, from all sources, that is anticipated to be without risk of adverse effect. The US EPA adopted the reference dose value cited in the NAS perchlorate report that was supported by the majority of the NAS committee. It is important to note that the NAS committee was not unanimous in their views on this matter.

What is Perchlorate?

Frequently Asked Questions: Perchlorate
Ammonium 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.

How Might I be Exposed to Perchlorate?

Frequently Asked Questions: Perchlorate
Human exposure to perchlorate can occur if contaminated water is consumed directly, is used to make beverages such as tea, coffee or formula, or is used to cook foods that absorb a significant amount of water. Perchlorate has also been detected in several types of foods and beverages (e.g. some lettuces and milk, depending on where they are from), possibly from use of perchlorate contaminated irrigation water or feeds.

Why are standards are necessary?

Gigateway - Opening the door to geographic Information
Metadata standards and consistency are necessary to ensure that comparisons can be made by users about the suitability of data from different sources. This means, for example, when comparing metadata about property or hazardous waste there is an indication of the dates to which the information refers, or if comparing metadata about different map sources the relevant scales are shown. Without standards validated metadata meaningful comparisons cannot be made.

Have any states set their own standards?

Apyron Technologies | air and water treatment solutions | FA...
a result of the continued delays by the U.S. Environmental Protection Agency (EPA) on this issue, several states initiated their own legislation to implement a more stringent standard prior to the EPA's final ruling on November 1. State government agencies in New Hampshire, New Jersey and Vermont have drafted new laws that will bring the MCL from 50 to 10 parts per billion (ppb). These proposals are currently under review by the states' respective legislative committees.

What Are The Health Effects Of Perchlorate?

Frequently Asked Questions: Perchlorate
sufficient 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.

What is the best way to remove a set when a soak-off is necessary?

Polished Nail Systems is very easy to soak off. Properly done, it should take only 10-15 minutes. Since this is only done once every 6-8 weeks, this is actually much less salon time spent than drying polish weekly or bi-weekly. Put client's hands in acetone for 10 full minutes without removing them and cover with a towel to retain body heat

What are screening standards and how do I set them?

Quality Tenant Screening FAQs
Screening standards are nothing more than decisions you have made in advance about the minimum qualifications a tenant who wants to live in your property must have. They generally cover financial capacity, rental history, credit history, family size, and, sometimes, criminal background. These standards should be realistic. Making them too lax invites problems in the future, but making them too stringent could take you right out of the market.
