        <description><![CDATA[The quote from the press release, &quot;septic tanks, such as those used at the state parks, may be less effective at containing pollution,&quot; is significant. Oregon's coast has more than 80 State Parks. Most of these are day use only, but that's still a lot of public toilets. And you're as likely to find regular colas involved as coffee, a potentially potent combination. There are also a number of well-used campgrounds including both Carl Washburne and Cape Lookout State Parks, among the highest concentration areas mentioned in the article.]]></description>

        <description><![CDATA[Readers comments about Astoria s warmer waters caused by the warmer Columbia river are indeed correct. The west coasts cool waters are due to upwelling and the flow of colder North Pacific waters moving south. There is no Alaskan Current moving south however. It is the California Current which flows south. The Alaska current flows north. I pay attention to these sort of things as a former N Pacific and Alaskan commercial  fisherman.]]></description>

        <title><![CDATA[What removes caffeine from sewage?]]></title>
        <link><![CDATA[http://www.smartplanet.com/forum/discussions/1-11279-75716]]></link>
        <description><![CDATA[The article implies that sewage treatment plants remove caffeine, but septic tanks do not. Since most sewage treatment plants don't do much more than let natural bacteria &quot;process&quot; the sewage (i.e., they do no chemical processing), it seems the caffeine can't be that hard to get rid of. On the other hand, it does does survive the trip from the septic tank through the ground to the ocean, so it must be somewhat persistent. I wonder if it naturally dissipates in the ocean, and if so, how long that would take?]]></description>

        <title><![CDATA[They've been testing streams and lakes for a long time]]></title>
        <link><![CDATA[http://www.smartplanet.com/forum/discussions/1-11279-75711]]></link>
        <description><![CDATA[Scientists for a long time have been testing for chemicals and drugs that humans, um, process and release into streams, rivers, and lakes. This is a big issue in the inland US, where one town processes its sewage, releases it into a stream, and then the next town downstream draws from the same stream for its drinking water.Most people don't realize it, but if their drinking water is taken from a lake or stream, they're literally drinking someone else's urine and wastewater. Modern sewage treatment plants are very good at taking out solids (garbage, feces, etc.) and killing bacteria, but they can do absolutely nothing with dissolved chemicals. In most inland cities, the runoff from streets following storms or snow melts also goes directly into streams or rivers without any treatment at all (which is why you shouldn't dump your used motor oil down the storm drain). What modern water systems rely on is that these chemicals are so diluted by the rest of the stream or lake water that it isn't an issue. Even so, excreted hormones are suspected of triggering earlier than normal puberty in children.Of course, in Chicago the issue of the Chicago river dumping wastewater into Lake Michigan (where the city gets its drinking water) was so bad that they reversed the flow of the river so it dumped its water eventually into the Mississippi instead.Anyway, given the issue with dissolved chemicals in inland waters, it's not so strange that scientists would wonder about the situation near coastal cities.]]></description>

        <description><![CDATA[You both make valid points, Ddugger and Omb, which brings me back to wondering why the scientists embarked on this research in the first place. Of all the things to test for, I'd like to have been there (or maybe not!) when some PhD said &quot;I know, let's analyze the Pacific for caffeine.&quot; Huh? What's next, dredging the Mississippi for saccharin?But now that they've done it, and to address your main point: The researchers seem to regard beverage and food as the main source of the caffeine. They also say that pharmaceuticals released some of the stuff. They RULE OUT natural sources. From the press release (link in the story): &quot;Caffeine is found in many food and beverage products as well as some pharmaceuticals, and caffeine in waterways is directly related to human activity. Although many plant species produce caffeine, there are no natural sources of the substance in the Pacific Northwest. The presence of caffeine in ocean water may also signal additional pollution such as pesticides and pharmaceuticals.&quot;After all this, I'm still sticking with 3 morning cups of strong, black and preferably Italian roast. I'll do my best to leave it out of the ocean. Might be tough,  as I live on an Atlantic island.]]></description>

        <description><![CDATA[My first thought also was what natural sources of caffeine there might be.Of all the substances consumed by humans, it seems caffeine would be low down on the scale.  Seems like you might find even higher concentrations of antibiotics and other medications, ammonia and who knows what else?I, too, have to wonder if someone in the lab didn't spill a spot of coffee!]]></description>

        <description><![CDATA[I challenge the analyzers to look at the volumeteric dilution of caffeine in solution at the points studied that weren't immediately adjacent to a sewage outfall - and then analytically demonstrate their analytical equipment's ability to detect at levels that low. It doesn't take much of an area volume and the resulting dilution to get specific molecules like caffeine down below detectable levels - parts per trillion and even lower. In fact, if the analyst were heavy coffee drinkers, contamination from aerosols in the associated testing atmosphere might be more plausible.I'm all for eliminating coastal septic tanks, but this isn't a plausible way to demonstrate the need. Measuring phosphates and nitrates would be a lot more convincing that there is a local sewage problem. Anyone tested the local macro alga for caffeine-like molecule production? Lots of plants produce caffeine.]]></description>
