Water pollution is one of the most pressing issues facing humanity–and one that affects everyone on Earth. Water surrounds us and makes the world livable. We rely on water for drinking, hygiene, agriculture, and transportation. Known as a “universal solvent,” water can dissolve more substances than any other liquid on earth. Three-quarters of the fluid in humans is made up of water, and it is the primary medium in which biochemical reactions in the human body occur.
The importance of water to humanity cannot be overstated.
But there is an under-acknowledged and under-reported global water crisis today. According to UNESCO, “Globally, 2 billion people (26% of the population) do not have safe drinking water and 3.6 billion (46%) lack access to safely managed sanitation.” That lack of clean, potable water is largely a result of pollution and water degradation that damages our global water supply, including lakes, rivers, streams, and oceans worldwide. The world needs to address this problem with urgency, and it’s necessary to understand some basics about the underlying causes of water pollution.
Aquatic pollution results when harmful substances contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment. These substances could be chemicals from agricultural runoff, pathogens in stormwater runoff and sewage, or oil spills from tankers, factories, farms, cars, and trucks.
The pollution is categorized as either “point source” or “non-point source” pollution:
Point source pollution of water resources is contamination that originates from identifiable sources, for example, industrial discharges, sewage treatment plants, and other facilities that pour pollutants onto the land or into a water body. Point-source aquatic pollution is easier to monitor and regulate than non-point-source aquatic pollution because its origins are easily identifiable, and it is often subject to federal laws and regulations that govern its management.
Non-point source pollution of water resources comes from diffuse sources, such as agricultural runoff, precipitation, drainage, or seepage. When rain or melted snow moves over and through the ground, the water absorbs and assimilates any pollutants it comes into contact with, like pesticides, fertilizers, sediment, and oil, and deposits them into a stream which eventually deposits them into a lake. There are numerous aquatic pollutants in the runoff, so it is difficult to point to a single origin and more complex to manage.
Whether point source or non-point source, the effects of aquatic pollution are dire and ripple out from the locally affected area to large ecosystems and human communities.
If we do not take drastic action to change the trajectory of the water degradation and pollution problem, it will radically affect the quality of life on Earth. There will be diminishing sources of potable water, with those in less wealthy countries suffering the most. There will be permanent loss of species and habitats. For those who do survive as water becomes scarcer, there will be an increased prevalence of water-borne diseases.
As dire as the problem is, the development of new technologies provides hope that with concerted effort we can tackle the water degradation and pollution problem. A sustainable solution is nanobubble technology, which has been shown to help restore waterbody health in diverse environments. Not only does this technology provide efficient oxygenation and enhance natural oxidation to combat aquatic pollution problems like algae build-up, muck, and nutrients, but it also does so without chemicals or harmful side effects.
Moleaer’s nanobubble systems also have been proven to significantly increase oxygen and improve water quality in lakes and other water bodies. While conventional aeration technologies achieve less than 3% oxygen transfer efficiency at standard conditions (SOTE) per foot of water, third-party testing confirms that Moleaer’s nanobubble technology achieves >85% SOTE in just 2 feet of water, enabling dissolved oxygen (DO) levels to increase while using far less oxygen than any other aeration technology.
Introducing high concentrations of nanobubbles into water increases the dissolved oxygen levels throughout the water column and into the sediment layer promoting the growth of beneficial bacteria that naturally break down muck and manage nutrients. More beneficial bacteria help immobilize and convert excess nutrients such as nitrogen and phosphorus into less harmful forms, which reduces algae proliferation.

In addition to technologies, there is the real work of educating the public, the vast majority of whom do not know about the existence of this problem or its severity. Many organizations are working on water-related problems advocating for change with elected officials, working to implement policies that do get enacted and providing resources and education where needed most.
They often fund research projects as well as support lobbying and advocacy programs on the factors that cause water pollution. This is not an exhaustive list but is meant to direct interested people who want to create change to organizations that are working to alleviate the water pollution problem.
Water pollution is an urgent problem facing the global community and we must understand the factors that cause water pollution and degradation. It will take the implementation of effective technological advancements, hard work by dedicated organizations, and strong government policies to make meaningful change. The effort requires global collaboration across diverse local, state, and national governments.
