[edit] The polemic

In 1995 high levels of MTBE were unexpectedly discovered in the water wells of Santa Monica, California. Subsequent tests found tens of thousands of contaminated sites across the country. MTBE in groundwater is a health risk, and it also ruins the taste of the water even at low concentrations. The leakage problem is attributed to the intrinsic risk of underground tank leakage or fuel spills and to the lack of effective regulations for underground storage tanks. In many states the presence of MTBE is treated much more aggressively than mere fuel contamination, and correspondingly the cleanup costs can be much higher. MBTE is an extremely mobile chemical in groundwater. The fact that the EU does not predict the same problem in Europe may be merely indicative that the EU trails the U.S. in most technology areas of water pollution. [1]. This report for the EU is severely flawed to the extent of laughable. It is self serving to placate the EU continued use of MTBE. Its level of analysis is primitive. For example, it dismisses the California experience with MTBE, saying California does not have sufficient precipitation compared to Europe to flush out the aquifers!

I reverted this to the old version, since this text adds a polemic tone to the article. This is not a discussion forum. When it's unknown, an encyclopedia states it's unknown. An encyclopedia doesn't argue for a specific point of view, possibly only mentions it. Some other changes were also made in the article, re-wording towards a political attack on MTBE, but I think that there's no reason to discuss those. Gasoline, especially reformate, contains quantitative amounts of carcinogens such as aromatics. --Vuo 14:03, 26 January 2006 (UTC)

[edit] More polemic

I added the POV tag to the section that clearly is trying to paint one political party in a negative light. Deli nk March 9, 2006

I'd like to point out that it doesn't make the text POV if you don't like it. Would it be counterfactual to say that the Republican party supports the big industry viewpoint? Nevertheless, what irks me in it is assuming MTBE is the evil. That's purely politicizing and hostile, and this problem should be solved without removing "inconvenient" facts from the article. (Namely, Big Oil funding.) Furthermore, if it's a fact that the US fuel distribution system cannot be trusted with a groundwater-polluting chemical, it may be stated in the article. --Vuo 19:41, 9 March 2006 (UTC)

[edit] lets fix it instead of tagging it and just talking about it

i didnt author any of the contentious text in this subsection, so i have no stake in the present version...why dont others assert which paragraphs need work or whether a counter point of view should be expressed. i dont like the way this subsection reads, but we owe it to the readers to get this right...im willing to help, but why dont the generators of this discussion declare the issues of clean-up..thank you sincerely Anlace 18:34, 9 March 2006 (UTC)

I replaced the article POV tag with the section POV tag. I haven't otherwise touched this section either. It contains a listing of legislative and judicial actions referenced with a half-dozen external links. The only part not referenced is the paragraph on political contributions. If no one weighs in with suggestions within a reasonable period, the tag should be removed. --Blainster 19:21, 9 March 2006 (UTC)
Sorry about adding an article POV tag instead of section POV tag. I'm not a very political person myself, but when I read this article, the section on legislation in the United States does not appear to be written from a neutral point of view. It appears to be written to lay blame on Republicans. Even if every statement is factual and referenced, that doesn't make it neutral. For example, stating that manufacturers donated to the Republican party may be true, but I would be extremely surprised if they didn't donate to both political parties. Mentioning one and not the other is done to make a political point. (The issue of political contributions seems to be somewhat trivial in any case.) I don't feel familiar enough with the topic at hand to make the changes myself, which is why I just posted the tag - to stimulate discussion among those who are knowledgable enough to do so. Anlace, can you please elaborate on what you mean by "i dont like the way this subsection reads"? Are your concerns the same as mine, or are there additional concerns? Deli nk 19:42, 9 March 2006 (UTC)
yes my concerns are pretty much the same as you have stated deli...beyond that i think the writing is poor. it seems as though a lot of good could be done just taking the factual material and making it more matter of fact...maybe the republicans are being bought off or maybe as you say both parties are on the take from the MTBE industry..who knows...but the information in this article is more suggestive than providing proof, cheers Anlace 20:21, 9 March 2006 (UTC)
i fixed some of the glaring NPOV items, but more work needs to be done. i dont think we can just delete material, since most of the material is rooted in factAnlace 03:16, 11 March 2006 (UTC)


i tried to fix all NPOV items, adding balance, removing extreme adjectives and removing speculation about future MTBE legislation. i am open to the changes others might offer and dont consider the section perfect, but good enough to remove the stigma of the tag, regards Anlace 06:04, 16 March 2006 (UTC)

[edit] "Modern computer-controlled, fuel-injected automobile engines produce negligible air pollution."

I've heard this before -- it's currently in the 'Alternatives' section -- and it seems to reference emissions on modern cars only in reference to emissions produced by older cars. As such, it's a potentially misleading claim, as alone it could be taken to mean that modern gasoline cars do not emit pollution, which is of course not true. And to be honest, for all I know it's not even remotely true, even in comparison with 'older' cars.

I marked it with citation needed but if there's a better way to note this as potentially misleading please let me know. --Andymussell 02:10, 11 March 2006 (UTC)

[edit] Correction

Shouldn't the units here be ppm? =="MTBE ruins the taste of water even at low concentrations of 5–15 mg/liter."==

units are correct at pbb Anlace 02:47, 11 May 2006 (UTC)

[edit] Gasohol carcinogenity, not ethanol

Ethanol is a carcinogen in the context of gasoline additive, since it increases the vapor pressure of the gasoline. But, the point is, that MTBE is not appreciably carcinogenic. MTBE has toxicity, but not this kind. --Vuo 01:48, 11 May 2006 (UTC)
