Environmental Working Group

Environmental Working Group - An environmental group says laboratory tests show the presence of a toxic chemical in 31 of 35 cities, with Honolulu having the second to highest level.

The nonprofit Environmental Working Group said hexavalent chromium, the same chemical that led to a $333-million legal settlement described in the movie "Erin Brockovich," is present in higher than recommended levels in Honolulu's water supply.

Drinking water from one location that was tested in Honolulu had 2 parts per billion of hexavalent chromium, compared to .06 ppb proposed as a public health goal by the California Environmental Protection Agency, the group said.

Rebecca Sutton, the group's lead investigator, said the Honolulu Board of Water Supply did not know the source of the hexavalent chromium. She said the chemical is a common industrial contaminant and can also originate from natural, geologic sources such as ground water.

"Regardless of the source of contamination, we need safe drinking water," she said.

The Honolulu Board of Water Supply said it doesn't test for hexavalent chromium because the federal Environmental Protection Agency does not require it.

Board spokesman Kurt Tsue said he was "surprised" at the Environmental Working Group's evaluation since it ranked Honolulu sixth as the best drinking water in the nation earlier this year.

Tsue said the board does test for chromium, but cannot tell how much of it is hexavalent chromium. He said the board has met the federal guidelines for chromium, with a maximum contaminant level of 100 ppb.

Sutton said the single water sample tested from Honolulu was taken from a residence in the general vicinity of Wilhemina Rise in east Oahu. She said taking more samples would have been better but her organization was constrained by the cost of testing.

She said she felt confident that sampling other residences would bear similar results.

Urban Meyer Stepping Down

Urban Meyer Stepping Down - Well, it appears as if it’s deja vu all over again.

Less than 12 months after retiring and then un-retiring, Urban Meyer is apparently stepping down as Florida’s head coach. There’s no word on if he will be stepping back up tomorrow.

Urban Meyer Stepping Down

According to Todd Wright of Sporting News radio, GatorUpdates.com and AOL Fanhouse‘s Brett McMurphy Meyer will announce at a 5 p.m. ET press conference Wednesday that he is resigning/retiring as the Gators’ head coach. There are no further details available at this time, other than GatorUpdates reporting over the weekend that Meyer checked into a hospital the week of the UGA game and has been undergoing tests since.

Obviously, we’ll have more on this story throughout the day and well into the night…

Matt Cassel Undergoes Appendectomy

Matt Cassel Undergoes Appendectomy - The mystery of Matt Cassel missing practice Wednesday coupled with the Kansas City Chiefs promoting quarterback Tyler Palko has been solved.

The team has announced that Cassel underwent an appendectomy on Wednesday morning. The Chiefs say they expect Cassel to return to work this week. Returning to work and being ready to perform well in the team’s biggest game of the season on Sunday against San Diego are two different things. ESPN’s Adam Schefter is reporting the Chiefs are viewing Cassel as being questionable to play in the game.

Clearly, this is terrible timing. The Chiefs are 8-4 and would take a major step toward the playoffs with a win over the Chargers. Cassel has played very well for the past two months. If he can’t play, the brittle Brodie Croyle would face the Chiefs in his first action of the season. Croyle last played in Week 13 of the 2009 season.

100-calorie Packs Diet

100-calorie Packs Diet - Did you know recent studies show chronic dieters tend to consume more calories when foods and packages are smaller? Consumer behavior was observed in the study regarding "mini-packs," 100-calorie food packages that are marketed to help people control calorie intake.

The study revealed that one group that over-consumes the mini-packs is chronic dieters - individuals making a conscious effort in trying to manage their weight and food intake.

This shows that the distorted perception of small packages may actually undermine dieters' attempts to limit calories.

Consider this: Consumers perceive the mini-packs to be a generous portion of food - numerous small food morsels in each pack and multiple mini-packs in each box - while on the other hand, consumers perceive the mini-packs to be diet food. For chronic dieters, this perceptual dilemma causes a tendency to overeat, due to their emotion-laden relationship with food.

In a series of focus group studi…
