Apart from man, climate changed caused harmful effects on the water quality.

Increase in rainfall from a changing atmosphere is probably going to affect water quality negatively. It will bring about more toxic and harmful algal blooms researchers. This is according to researchers and their studies.


A consortium of science researchers declared the results of their studies in Science on Thursday. The study details how they utilized advanced computer models in gauging how water quality will be change. These changes are caused by rising temperatures as well as increased precipitation.

One of the co-authors and researchers is Anna Michalak from the Carnegie Institute of Science. According to her interview with The Court House News, the findings demonstrate that it’s imperative that the quality management strategies of water are accountable. It impacts the future precipitation changes when it comes to nitrogen loading.

Two scientists also have the same findings. Eva Sinha from Carnegie and Venkatramani Balaji from Princeton University concentrate on this topic. They find that the increase in rainfall affects the presence of nitrogen when it comes to the water system.


Nitrogen is a typical fixing in compost. It is also found a lot as a leftover from fossil-fuel combustion. This means an increase in rainfall could wash an abundance of this element into waterways, streams, lakes and even in the sea.

According to the National Science Foundation, it’s additionally a food for algae. That is why the dangerous algal blooms that have distressed Lake Erie the other bodies of water all throughout the Midwest have been more frequent and more dangerous.

There are a lot of dead zones in the coastal region all over the United States. This includes Florida, the Gulf of Mexico, and in the Chesapeake Bay. These areas garner the attention of regulators, journalists, and even ordinary citizens of the United States.


According to the study’s result, the nitrogen-loading issue will be particularly pronounced in the Midwest and the Northeast. These areas have an abundant source of fertilizer. These areas produce the agricultural products of the country.

The expansion in dangerous algal blooms is only a part of the problem. Nitrogen-loading in lakes is also a part of the issue.

Nitrogen-loading in lakes leads to eutrophication. Lakes turned into muddy brown and lost clarity. This is not only an insightful incident, but it can also cause harm to the health of people.

According to the study, the frequency of storms and heavy precipitation in the areas are one of the reasons. Although there are already laws governing the nutrients that farmers and factory use, climate plays a significant role. Climate change determines the health of the bodies of water.

The researchers also found out that there are different climate models. There are 21 different climate models that predict the runoff under different climate scenarios.

There are lots of things to do and to consider in decreasing the effect of these scenarios. Regions need to reduce the use of products that have nitrogen. This includes the use of fertilizers.

Although the researchers conducted the study in the United States, it is not only the country facing this problem. China, India, and Southeast Asian countries face this problem too.
