弗莱水源污染（警报）

2008年10月28日17年前

由于城市北部发生化学品泄露，环境官员纷纷该地区的地下水系统是否已经全部被污染。泄露事故发生在星期一，地点是位于Melissa Steet的Custom Machine和Hardchrome Inc。
环境官员说，超过2700公升（600加仑）的铬酸没能被遏制住，其中一些流入化粪池系统，被水所稀释。环境部督察Jeff Williams说：“当地居民不应当饮用当地的水源，而是应该购买饮用水。”Jeff Williams担心这些铬酸会随着地下水向四周扩善。同时NB省卫生部门也警告弗莱居民不要饮用当地的水源。泄漏事故发生原因仍在继续调查中，以确定受污染的面积。

看来大家只好买饮用水来饮用了

楼主

[SIZE="3"]发生泄漏地点在Melissa Steet，而Melissa Steet距离Saint John River仅有3公里的距离。如果连Saint John River都受污染，那么污染面可就广了，弄不好半个NB省都会受影响。[/SIZE]

A northside chemical spill has environment officials scrambling to determine if and how bad the groundwater system in the area may have been contaminated. The incident occurred early Monday morning or overnight Sunday at Custom Machine and Hardchrome Inc., located at 85 Melissa St. in Pepper Creek.

CHEMICAL SPILL INVESTIGATED: Provincial environment inspector Jeff Williams goes through his paperwork outside a business on Melissa Street. The department is investigating a chemical spill at a business in Pepper Creek. It’s unclear how far the chemical, chromium acid, has spread.

TESTING AT business LOCATION: Workers stand outside Custom Machine and Hardchrome Inc. on Melissa Street on Monday where a chemical spill occurred.

Officials said more than 2,700 litres (600 gallons) of chromium acid escaped containment, some of which leaked into the facility's septic system. It was in a flake form but was diluted with water.

The Fredericton Fire Department along with the Department of Environment responded to the incident and were at the scene most of the day.

A consulting firm has been hired and will be giving officials a briefing as soon as possible as to how far it believes the product may have travelled.

Jeff Williams, an inspector with the Environment Department, said some people should take precautions.

"Right now, I have told the immediate area - of this property ownership anyway - that they shouldn't be drawing water," Williams said late Monday afternoon. "They should be buying drinking water."

Williams said he's still waiting for the results of the assessment to determine how far an advisory should go.

"I am not saying there is a danger; I am just saying we don't know," he said. "In groundwater, it does spread quickly. At this point, we don't know how far it's gone.

"We don't know if it's in fast aquifer, where it would run fast, or is it sitting in stable groundwater?"

Because of the dilution factor, Williams said a plan is being devised to determine how far out of the affected area any advisory should go.

Pepper Creek is outside city limits and the lots aren't serviced.

The affected business is one of four contained in the same shopping-centre type structure. At least one other business was impacted by the spill.

"We know that on this particular (location) the well has been impacted," Williams said. "What I have advised is that we do not draw water at this point until we do further assessment. I told the responsible party for this spill to call their insurance (company)."

Bob Martin, assistant deputy chief of operations with the Fredericton Fire Department, said a large part of the cleanup has already been accomplished. Six barrels of the product have been contained in a liquid form and about 40 bags of used absorbent have been reclaimed.

"It's a dangerous product; we're treating it very seriously," Martin said. "The big thing to us is that if it gets in the waterway, it's a danger to fish and things like that. (But) we're pretty comfortable that it actually hasn't left that area yet."

Glen Allen, who operates Custom Machine and Hardchrome Inc., said he expects his business will be shut down for a while, at least until testing is completed at that location.

An investigation into what caused the spill is continuing.

做了点RESEARCH

这次泄漏的主要物质为Chromic acid 这是它的通俗叫法，化学专业名称为 chromium trioxide，一般和硫酸混合，用作工业上的涂层保护物质，不过这是以前。

后来由于越来越多的处于环境和健康方面的考虑，很多工业都停止使用这一物质。

其被氧化后形成的Hexavalent chromium有很强的毒性。

就我浅薄的化工知识来讲，chromium有4个电子层，其最外层只有1个电子（chromium 极性(dipole)比较特殊，按照理论上来讲其24个电子，最外层因该有6个才对。）。也就是说其化合物非常的稳定。很难通过沸煮开水等方式将其分解，而于活性有机物反应后生成六价的chromium将比三价的chromium的更危险。

唉～～～家里没水了，只有酒一大堆，难道要我今天一醉方休不成？？？？？？？？
