In general, when water is polluted it is called, surprisingly enough, water pollution. Specifically, livestock waste and agricultural chemicals would be chemical water pollution (since there are chemicals dissolved in the water), to differentiate these from particulate pollution (soot, silt, and clay suspended in the water).Excess Nitrates from organic or inorganic fertilisers can also cause severe algal blooms. this process is called Eutrification.
