The dangers of swimming in polluted water
Lake Michigan is a significant source of drinking water for millions of people, but it is also a popular destination for swimming and other recreational activities. Unfortunately, the lake faces a severe plastic pollution problem, with an estimated 11 to 22 million pounds of plastic entering it every year. This plastic does not simply disappear but instead breaks down into microplastics, which can continue to contaminate the water and pose risks to both the environment and public health.
Children, the elderly, and individuals with weakened immune systems are particularly susceptible to developing illnesses or infections after swimming in polluted water. Those who make full body contact with the water or have exposed cuts are at an even greater risk of adverse health effects. Sewage overflow during rainstorms or heavy rainfall can cause untreated water containing harmful bacteria, viruses, and parasites to contaminate beach areas. This contamination can lead to elevated levels of pathogens and bacteria, increasing the likelihood of beach closures due to health risks.
To protect yourself and your loved ones, it is essential to be vigilant about water quality and follow local advisories and notifications regarding beach closures. Checking for visible signs of pollution, such as discharge pipes or stormwater runoff, and avoiding swimming in these areas is crucial. It is also recommended to avoid submerging your head when swimming and to refrain from swimming if you have any breaks in the skin, such as cuts or open sores. By taking these precautions, you can help minimize the health risks associated with swimming in polluted water.
While beach cleanups are essential in mitigating the amount of plastic pollution in Lake Michigan, they are not enough to solve the magnitude of the problem. A more systemic solution is required, including reducing the production of single-use plastic and holding producers responsible for the environmental impact of their products. By addressing the issue at its source, we can make a more significant and long-lasting impact on protecting the lake and the health and safety of those who enjoy its waters.

Beach cleanups by volunteers
Volunteers play a crucial role in cleaning up beach pollution in Lake Michigan. One notable volunteer effort is the Adopt-a-Beach program, led by the Alliance for the Great Lakes. This program engages thousands of volunteers each year in shoreline cleanups on all five Great Lakes, including Lake Michigan. Volunteers remove trash, with a focus on plastic pollution, and collect valuable data on litter composition.
The Adopt-a-Beach cleanups are locally organized, with volunteer Team Leaders guiding groups of participants in cleaning their local beaches. The program is designed to be accessible, requiring no long-term commitment. Individuals, families, schools, and businesses can all participate and contribute to making a difference in their communities.
During the cleanups, volunteers collect and properly dispose of litter, with an emphasis on recycling. They also record the number and type of trash collected using standard forms, such as the Litter Monitoring Form. This data is then entered into the Alliance for the Great Lakes' online data entry system, contributing to a broader understanding of coastal litter in the Great Lakes region.
The data collected by volunteers is of significant value. It helps scientists study the sources of plastic pollution and informs policymakers in their decision-making processes. For instance, the data revealed that about 85% of the trash collected in the Great Lakes region is plastic. This information strengthens the case for policies that address plastic pollution and protect the lakes.
While beach cleanups by volunteers are essential, it is also recognized that they are not a standalone solution to the magnitude of the plastic pollution problem in Lake Michigan and the Great Lakes region. A more systemic approach is needed, including reducing the production of single-use plastic and holding producers responsible for the environmental impact of their products. Nevertheless, volunteer efforts remain a vital component of community engagement and contribute to the overall health of Lake Michigan and its surrounding ecosystems.

The use of technology to combat plastic pollution
Plastic pollution is a serious problem for the Great Lakes, which include Lake Michigan. The Rochester Institute of Technology estimates that more than 22 million pounds of plastic pollution end up in the Great Lakes annually, with around 11 million pounds entering Lake Michigan alone.
Beach cleanups, such as those organized by the Alliance for the Great Lakes' Adopt-a-Beach program, are a great way to keep plastic out of the lakes. However, they are not enough to solve the magnitude of the problem. A more systemic solution is needed, and technology can play a crucial role in this regard.
One technological approach to combat plastic pollution is the development of advanced recycling methods. While traditional recycling can only handle a fraction of plastic produced each year, innovative recycling technologies aim to improve the recyclability of plastics. For example, chemical recycling, or advanced recycling, uses chemical processes to break down plastics into their molecular components, allowing for the creation of new plastics with the same properties as the original. This technology has the potential to divert plastic waste from landfills and waterways, reducing the environmental impact of plastic pollution.
Another way technology helps is by providing data and insights to support legislation and policymaking. Volunteers with the Adopt-a-Beach program, for instance, collect data during shoreline cleanups that help scientists study the sources of plastic pollution. This data is invaluable in making the case for solutions and influencing decision-makers. Additionally, organizations like Environment Illinois and the Alliance for the Great Lakes work to support legislation that addresses plastic pollution on multiple fronts, including production reduction, improved reuse systems, and better data for policymaking.
Furthermore, technology can assist in the detection and monitoring of plastic pollution. For instance, researchers have employed technology to study the presence of microplastics in the Great Lakes. They found high levels of microplastics in all five Great Lakes, including Lake Michigan, which poses a risk to both the environment and public health. By using technology to detect and monitor plastic pollution, we can better understand the extent and impact of the problem and develop more targeted solutions.
Finally, technology can offer alternatives to plastic products and packaging. For example, the development of biodegradable materials and compostable alternatives can reduce the reliance on single-use plastics. Additionally, businesses are becoming more aware of the issue, with some restaurants in Chicago voluntarily phasing out straws and single-use plastics. These technological alternatives and behavioral changes work together to combat plastic pollution.

Reducing single-use plastic production
Plastic pollution is a serious problem for the Great Lakes, which provide drinking water for 40 million people. It is estimated that about 11 million pounds of plastic enter Lake Michigan alone each year. Single-use plastics are a major contributor to this pollution, with items like plastic forks, straws, and broken bits of foam commonly found on beaches.
To reduce single-use plastic production and protect Lake Michigan, here are some key strategies:
Policy and Regulatory Approaches:
- Governments at the federal, state, and local levels should reduce the production and use of single-use plastics, phasing out the most toxic and harmful products. This includes implementing bans on specific single-use plastic items, such as plastic bags, straws, and takeout containers.
- Hold producers responsible: Shift the burden of managing plastic pollution from consumers to producers. Encourage or mandate the use of sustainable production practices, such as using renewable energy and recycled materials.
- Extend producer responsibility: Ensure that manufacturers are responsible for the entire life cycle of their plastic products, including disposal and recycling. This can be achieved through extended producer responsibility (EPR) policies.
Corporate Initiatives:
- Companies should reduce the use of single-use plastics in their packaging and products. They can pilot reuse and refill systems and design products with reusability and recyclability in mind.
- Large corporations, such as Coca-Cola, Nestlé, and Unilever, should take responsibility for their significant plastic production and actively work to reduce it. They can also invest in and promote reusable alternatives.
Individual Actions:
- Individuals can reduce their single-use plastic consumption by choosing reusable alternatives whenever possible. This includes using reusable bags, bottles, cups, and cutlery.
- Avoid individually packaged goods and support zero-waste shops that encourage the use of refillable containers.
- Compost food waste and store leftovers in reusable containers to reduce the use of plastic takeout containers.
- Support local plastic bans and advocate for policies that reduce single-use plastic production. Contact companies to express your concerns about their packaging choices.
By combining these approaches, we can significantly reduce single-use plastic production and protect Lake Michigan from plastic pollution.

The health risks of contaminated water
Contaminated water poses a serious threat to human health. It is estimated that unsafe water causes 1.8 million deaths each year, with a further 1 billion people falling ill annually due to contaminated water. The health risks of contaminated water are varied and depend on factors such as the type of contaminant, its concentration in the water, individual susceptibility, the amount of water consumed, and the duration of exposure.
Water contamination can cause gastrointestinal illnesses, nervous system or reproductive issues, and chronic diseases such as cancer. Exposure to high doses of chemicals can lead to skin discolouration, nervous system or organ damage, and developmental problems. Even exposure to low doses of contaminants over a long period can have serious health consequences, such as cancer. Waterborne pathogens, in the form of bacteria and viruses from human and animal waste, are a major cause of illness from contaminated drinking water. Diseases spread by unsafe water include cholera, giardia, typhoid, hepatitis, and gastroenteritis.
Children, the elderly, and those with weakened immune systems are particularly vulnerable to the health risks of contaminated water. People who make full-body contact with the water or those with exposed cuts are at greater risk of infection. It is important to check for alerts and signage about potential health risks at beaches and swimming areas, and to avoid swimming at beaches with visible discharge pipes or after heavy rainfall.
Water pollution also has a significant impact on marine life and ecosystems. Marine animals can suffer health problems, reduced lifespans, and reproductive issues due to water contamination. Contamination can reduce biodiversity and endanger the food supply for various marine animals. When water pollution causes an algal bloom, it can reduce oxygen levels in the water, creating "dead zones" where plants and animals cannot survive. Chemicals and heavy metals from industrial and municipal wastewater contaminate waterways, reducing the lifespan and reproductive ability of aquatic organisms.
The Great Lakes region, including Lake Michigan, is particularly affected by plastic pollution. It is estimated that about 11 million pounds of plastic enter Lake Michigan each year, breaking down into microplastics that can continue to contaminate waterways and pose a threat to public health. While beach cleanups can help remove litter and plastic pollution from shorelines, a more systemic solution is needed to address the magnitude of the plastic pollution problem in the Great Lakes.
