tbhurst discovered 5 months ago- From the page: "So naturally when scientists found upwards of 2.0 ppm of ammonia in major Iowa streams this spring, they were concerned. The extremely high levels were caused by a combination of agricultural chemicals and heavy ice cover. Apparently, much of the ammonia that would have ended up in the atmosphere was trapped by the ice and became runoff during spring thaw. In and around Des Moines, water officials had to turn to alternative sources to supply the city's water."
