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.

MassDEP is establishing perchlorate standards to ensure that public health is protected and to facilitate the cleanup of perchlorate sources.

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.

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.

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.

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.

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.

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.

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.

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.

Alaskan educators, political leaders, parents, business people, and others have joined together to create a vision of excellence for all children in Alaska. As a result, the State Board of Education & Early Development has adopted, and recommends that all school districts adopt, a number of standards to guide students' educational experiences.

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.

As noted in the answer to Question No. 16, drinking water suppliers have taken action to address contaminated sources. Some suppliers have removed sources from service, while others are using wellhead treatment technologies to remove perchlorate from the drinking water sources. In addition, some systems are using blending to reduce perchlorate levels in water prior to delivery to the public.

Yes. The Macuscope™ is registered with the FDA as a class 1 exempt device and is manufactured in an FDA-approved facility to standards set by the FDA. There are currently no other medical instruments that measure macular protective pigment density that can make these claims. The MacuScope™ will meet comparable medical and safety guidelines world-wide by years end.

No. The ACR only takes the information it is given by each individual and makes it available alongside that supplied by many other people. The checkboxes are supplied as a convenience for users to find the named morphs that are extremely common. If anyone wishes to register their corn as a "super flim flam spam" corn they can. If anyone wishes to register an amelanistic corn as an anerythristic, they can do so. It will be up to the users to decide whether or not the data is useful or accurate.

All examiners go through an intense calibration exercise before the exam to be sure that they grade as reliably as possible.

Select any section heading and a Compliance % box pops-up. Enter your required section compliance here. This allows you to set your own standards in your assessment and is also used to graph performance against compliance requirements. Note - if you enter a Compliance % for a section, you must enter compliance for all sections. Sub-sections roll-up to Section totals (see reports above).

There are no specific POST Board psychological standards. The basic standard for most "industrial psychological exams" includes a recognized instrument such as the MMPI or CPI. A licensed psychologist can interpret these instruments, and in conjunction with a comprehensive personal interview, may predict how individuals will handle themselves; work within a given community; and interact with their peers and supervisors.

Sample if the policy allows (current policy requires a source of perchlorate and a human exposure pathway). Follow perchlorate business process established by Headquarters, U.S. Army Corps of Engineers (HQUSACE) (as administred by Hazardous, Toxic, and Radioactive Waste (HTRW CX)) and submit request for sampling to the HTRW CX for review and recommendation to the appropriate Division Commander regarding approval.
