The main sources of nitrogen pollution are surpluses of mineral fertilisers and manure which are washed out of agricultural soil to groundwater, rivers and seas by the rain. Most phosphorus pollution comes from households and industry. If appropriate mitigation measures are not in place, higher concentration of nutrients can be measured at bathing waters situated downstream of pollution sources, potentially leading to problems with public and environmental health. The consequences of such eutrophication can also include blooms of blue-green algae, which reduce water clarity and quality. Decomposing algae can also cause depletion of oxygen and induce fish kills (CSIRO, 2019).
