Excess nitrates and phosphates in rivers primarily originate from agricultural runoff, where fertilizers containing these nutrients are applied to crops and subsequently washed away by rainwater. Other significant sources include wastewater discharges from sewage treatment plants and industrial facilities, as well as urban runoff containing fertilizers from lawns and gardens. Additionally, livestock waste can contribute to nutrient loading in nearby water bodies. Together, these sources lead to nutrient pollution, which can cause harmful algal blooms and degrade water quality.
What else can I help you with?
What types of salts dissolve in rivers?
Examples are soluble salts as: sodium chloride and other chlorides, nitrates, sulfates, phosphates etc.
A waste product that gets into rivers and helps algae grow?
anything that contains either nitrates or phosphates. Manure, sewage, plant debris.
What may not be good for rivers?
Phosphates are bad for rivers, lakes, and oceans.
What is a waste product that gets into rivers and helps algae to grow?
nitrates
How do nitrates get into H2O?
Fertilizers used in agriculture are partially drained in lakes an rivers.
Are the sources of rivers found in oceans?
No, rivers flow into oceans, and "source" implies "from." Sources of rivers are found in the mountains.
How do nitrates used in fertilizer make their way into bodies of water like lakes and streams?
rain water and water used to irrigate crops can carry these nitrates to rivers and lakes
How phosphate cause pollution?
Phosphates are fertilizers. When excess amounts of phosphates enter bodies of water (rivers, lakes, etc.) there will be a tremendous growth of algae as a result of the fertilization. This algae will eventually form large masses of rotting vegetable matter which will deplete the oxygen in the water which kills all the fish. Then you have dead rotting fish along with the dead rotting vegetable matter, and the whole thing is very nasty.
Excess heat in rivers is caused by what pollution?
Thermal pollution causes a rise in the ambient water temperature in rivers. Excess heat often causes algal blooms and increased metabolism in aquatic animals. This results in a shorter life span for both the plants and animals.
Are ice rivers lakes and groundwater sources of salt water?
Ice, rivers, lakes, and groundwater are all sources of freshwater
Where do rivers start or have their sources?
oceans
Do rivers in Western Australia have their sources in eastern rainforests?
No, they do not. Their sources are in the west.
