What percentage of rivers in America are considered polluted?

    I cannot find any specific numbers or percentages on polluted rivers, however it is safe to say that most have been either disturbed or polluted in one way or another. Any river that contains agriculture in its watershed is likely polluted with fertilizer and pesticide runoff. Any river in which is close to construction of roads and/or buildings will be disturbed due to sediment runoff. This often leads to heavy metal and nutrient buildup in streams which will eventually pollute whatever waterway it runs into.
