Summary
Microplastic Menace: Threats to Drinking Water
- Microplastics, <5mm particles, contaminate water sources from various sources like wastewater treatment plants and stormwater runoff.
- They pose potential health risks as they can contain toxic chemicals that leach into water.
- Microplastics harm marine life, with ingestion and entanglement leading to serious consequences.
The world is living with an environmental disaster: microplastics. These little plastic specks (less than 5mm) have entered our water supply and are seriously harming our health and the environment. But while the plastic pollution problem has been widely talked about, the toxicity of microplastics has been generally neglected, even though they are found in tap water, bottled water and even in the air we inhale.
What are Microplastics?
Microplastics are microscopic pieces of plastic formed when large plastic pieces are broken down. They’re smaller than 5mm — small enough to swarm around and pollute the land. They are present in everything from cosmetics to household cleaners to clothing. These particulates get into our water from many different sources, from sewage discharge, stormwater runoff and the decomposition of larger plastic objects. The prevalence of microplastics has raised significant concerns about their impact on human health and the environment. Recent studies have detected microplastics in drinking water, indicating that these tiny particles could easily make their way into our daily lives. As awareness grows, researchers are urging for stricter regulations on plastic waste and better filtration systems to mitigate the entry of microplastics into our water supplies.
How Do Microplastics End Up in Our Drinking Water?
We have many ways in which microplastics can end up in our water. One way is by means of sewage treatment facilities, which flush treated effluent into rivers and lakes. This wastewater might also be high in microplastics that weren’t removed in treatment. Microplastics can get into our drinking water too, in the form of stormwater runoff, which funnels plastic particles from the streets and parking lots into rivers. Microplastics can also, last but not least, be generated by large plastics, like plastic bottles, which disintegrate to ever smaller pieces as they age and ultimately end up in our drinking water.
Effects of Microplastics on Our Health and the Environment
Microplastics have yet to be fully appreciated how harmful they are to human health and the environment, but there’s a clear sign that they can. The microplastics are actually full of harmful chemicals (such as bisphenol A (BPA)) that can escape into the water supply and cause health issues. Also, microplastics can hold and concentrate other toxic chemicals like pesticides and heavy metals to make them more toxic in their body when ingested.
And the presence of microplastics is destroying wildlife as well. Fish and seabirds will feed on microplastics, eating them and suffering health effects and death from them. It’s even possible for microplastics to actually injure wildlife by getting caught in their intestines or in their noses.
What Can We Do to Reduce the Presence of Microplastics in Our Drinking Water?
We as individuals and communities can do a number of things to help keep our water less polluted by microplastics. These include:
Reduce plastics used in one use, like plastic water bottles and straws. For instance, you can do this by using reusable water bottles and skipping disposable plastics where you can.
Helping wc’s flush microplastics out of wc’s. This can be done by demanding that such treatment facilities be better regulated and funded.
Helping to build new products that do not have microplastics in them. This can be done by opting for products that are free of microplastics and lobbying for new products.
Getting involved in beach clean-ups and other projects to get plastic out of the environment. This is by volunteering at cleanups or running your own cleanups locally.
Also governments need to step up to the plate to reduce microplastics. Such measures can be regulations regulating products using microplastics, investments in research and development of alternative products, and incentive schemes that motivate companies to use fewer disposable plastic products. Governments could also regulate wastewater treatment plants more strictly and encourage alternatives to plastic that are greener.
The Importance of Monitoring Microplastics in Our Drinking Water
You have to monitor them if we’re going to do anything about the microplastics that are in our water. That’s achievable by regular water testing and the creation of new technologies for removing microplastics from water. Water testing on a regular basis will identify the microplastics in our water and measure how much has been done to mitigate them. The new technologies for microplastics removal from water can, too, make sure that our water supply is clean and untainted by harmful contaminants.
The Role of Plastic Manufacturers
It isn’t just the plastic manufacturers that need to stop microplastics in our water supply. They could be more likely to ban microplastics from their products and develop alternative materials. They can also do their bit to see that their products are properly disposed of and not leaked into the environment and into our waterways. If plastic manufacturers own their own manufacturing, microplastics in our drinking water could be minimized and the planet saved by doing so.
Microplastics in Bottled Water
This issue of microplastics in our water goes the same way with bottled water. In time, plastic bottles degrade and let out microplastics into the water. And microplastics may cling to the water from the bottle plastic. That’s why you should stop using disposable plastic bottles and use reusable glass or stainless steel water bottles instead.
The Need for More Research
As we become more and more aware of microplastics in our drinking water, we’re not quite sure what they do to human health and the natural world. It is important to research more in order to learn how deep this hole goes and how to come up with solutions. This is in the form of examining microplastic sources, environmental and human health impacts, and the evolution of new technologies to clean our water supply of microplastics. If we invest in research, then this can be understood and addressed.
