Flint's Water Crisis: Pollution's Source Revealed

The Flint water crisis was a public health disaster that began in April 2014 when the city of Flint , Michigan, changed its water source from Lake Huron to the Flint River. This switch caused water distribution pipes to corrode, allowing lead and other contaminants to leach into the drinking water. Almost immediately, residents of Flint—a majority-black city where 40% of people live in poverty—started complaining about the quality of the water. Despite assurances from officials, the water remained unsafe, leading to a range of health issues for residents, including skin rashes, hair loss, and elevated blood lead levels, particularly in children. The crisis was the result of a series of decisions made by state-appointed officials aimed at reducing costs, as well as inadequate treatment and testing of the water.

The switch to the Flint River

The Flint water crisis began on April 25, 2014, when the city changed its water supply source from Detroit's Lake Huron to the Flint River. This decision was made by a state-appointed emergency manager, Darnell Earley, during a financial crisis in the city, with the aim of reducing costs. The Flint River had been the city's main water source until the 1960s, and the switch was intended to be temporary until a new pipeline from Lake Huron could be built.

The Flint River has a long history of being an unofficial waste disposal site for local industries, as well as receiving sewage, agricultural runoff, and toxins from landfills. Despite this, the city of Flint claimed that the river water was safe and that the switch was temporary. However, almost immediately after the switch, residents began complaining about the taste, smell, colour, and appearance of the water. Many reported skin rashes, hair loss, and itchy skin.

The water from the Flint River was highly corrosive, and officials failed to treat it properly, which caused the water distribution pipes to corrode and leach lead and other contaminants into the drinking water. Lead exposure can have serious health consequences, especially for children, and can impact brain development, growth, learning, behaviour, hearing, and speech. Studies found that the percentage of children with elevated blood lead levels increased after the switch to the Flint River water.

In addition to lead contamination, there were also concerns about bacterial contamination in the water. E. coli and total coliform bacteria were detected, leading to multiple boil water advisories and increased chlorine levels. The water was also found to have high levels of chloride, which led to corrosion issues in industrial settings, such as the General Motors engine plant.

Inadequate water treatment

On April 25, 2014, the city of Flint, Michigan, changed its water source from Detroit's water system to the Flint River. This decision was made by state-appointed emergency managers to save costs and provide a temporary water source until a new pipeline to Lake Huron could be built.

The Flint River has historically been an unofficial waste disposal site for local industries, receiving untreated refuse, raw sewage, agricultural and urban runoff, and toxic leachate. Despite this, the city of Flint had previously used the river as its main water source until the 1960s, when it switched to Detroit's water system.

When Flint switched back to the Flint River in 2014, the water was not properly treated, leading to inadequate water treatment and testing. This resulted in a series of major water quality and health issues for residents. The highly corrosive river water caused lead to leach out from aging pipes, exposing around 100,000 residents to elevated lead levels. E. coli and total coliform bacteria were also detected in the water, prompting boil water advisories.

The inadequate treatment of the Flint River water was due to a lack of preparation and proper equipment at the water treatment plant. Emails sent before the switch indicated concerns about staffing and monitoring plans, and it was later revealed that the plant lacked the necessary equipment for full-time operation.

The poor water quality had significant health impacts on Flint residents, especially children. Studies found elevated blood lead levels in children after the switch to Flint River water, which can cause reduced intellectual functioning, increased mental and physical health issues, and a higher risk of Alzheimer's disease later in life. Other reported health issues included skin rashes, hair loss, and itchy skin.

Governmental neglect

The Flint water crisis was a result of governmental neglect at the city, state, and federal levels. In 2011, the city of Flint was facing a financial crisis, with a $25 million deficit, and fell under state control. Michigan Governor Rick Snyder appointed an emergency manager to oversee and cut city costs. This led to the decision in 2013 to end the city's practice of piping treated water from Detroit and instead pump water from the Flint River, despite the river water being highly corrosive.

In April 2014, the switch to the Flint River was completed, marking the start of the water crisis. Almost immediately, residents began complaining about the taste, smell, and appearance of the water. The water was foul-smelling, discolored, and off-tasting, and caused skin rashes, hair loss, and itchy skin. Officials failed to properly treat the water, and as a result, lead leached from aging pipes into thousands of homes, exposing residents to elevated lead levels. Despite these complaints, government officials ignored, overlooked, and dismissed the claims, even as studies confirmed the presence of lead contamination in the water supply.

The inadequate treatment and testing of the water resulted in a series of major water quality and health issues for Flint residents. The Michigan Civil Rights Commission concluded that the poor governmental response was a "result of systemic racism." It was only due to the relentless efforts of the Flint community, supported by doctors, scientists, journalists, and activists, that the issue gained attention. In 2015, test results showing elevated lead levels in the water and in children led to a petition to the U.S. Environmental Protection Agency (EPA) to launch an emergency federal response, but the EPA failed to act.

In early 2016, residents and groups sued the city and state officials to secure safe drinking water. The Michigan Attorney General also announced an independent review to determine if any laws were violated during the crisis. In 2021, nine people, including Governor Snyder, were charged with various crimes related to the water crisis, including willful neglect of duty. Despite these charges and civil lawsuit settlements, none of the individuals in power have faced criminal penalties for their actions.

Health effects of lead exposure

The water crisis in Flint, Michigan, began on April 25, 2014, when the city switched its drinking water supply from Detroit's system to the Flint River in a cost-saving move. The river water was highly corrosive, and officials failed to treat it properly, leading to lead leaching out from aging pipes into thousands of homes. This resulted in a series of major water quality and health issues for Flint residents, including skin rashes, hair loss, and itchy skin.

Lead exposure can have serious health effects, particularly in children. Young children are more vulnerable to the toxic effects of lead as they are more likely to be exposed due to their tendency to put their hands or other objects, which may be contaminated with lead dust, into their mouths. Lead can be absorbed into the body through touching, swallowing, or breathing it in. Once ingested, lead quickly enters the bloodstream and can harm a child's health. Lead exposure can cause a range of health issues in children, including behavioural problems, learning disabilities, seizures, and in some cases, even death. It can also lead to long-term harm, including reduced intellectual functioning and IQ, increased issues with mental and physical health, and a higher chance of developing Alzheimer's disease later in life.

In adults, lead exposure can cause increased risks of high blood pressure, cardiovascular problems, and kidney damage. Additionally, lead exposure during pregnancy can result in reduced fetal growth and preterm birth. Lead is stored in the bones and can take decades to decrease, meaning that even low levels of lead in the blood can have negative health effects.

The health effects of lead exposure are entirely preventable, and it is important to take steps to reduce lead contamination in the environment, particularly in sources such as water, soil, and food. The CDC's Childhood Lead Poisoning Prevention program works to educate healthcare providers, parents, and educators about the risks of lead exposure and how to track developmental milestones in children to catch any issues early on.

Public health emergency response

The Flint water crisis was a public health emergency that began on April 25, 2014, when the city switched its water supply from Detroit's system to the Flint River, resulting in lead contamination of the water supply. This crisis highlighted the need for improved risk communication strategies, enhanced surveillance, and primary prevention to identify and address environmental threats to public health. Here is an overview of the public health emergency response:

Identification of the Issue

Residents of Flint quickly noticed issues with their water supply after the switch. They complained about the taste, smell, and appearance of the water, which was foul-smelling, discolored, and off-tasting. These complaints were chronically ignored by government officials, who failed to address the issue for 18 months.

Health Impact

The inadequate treatment and testing of Flint River water resulted in a range of health issues for residents, including skin rashes, hair loss, and itchy skin. The more severe consequence was lead poisoning, with elevated blood lead levels detected in both adults and children. Lead exposure is particularly harmful to children, causing damage to their brains and nervous systems, leading to slow growth and development, and resulting in learning, behavior, hearing, and speech problems.

Public Response and Advocacy

The residents of Flint, supported by doctors, scientists, journalists, and citizen activists, played a crucial role in bringing the water crisis to light. They advocated for their rights and pushed for a resolution, even in the face of government inaction. This united response from the community forced the government to acknowledge the issue and take steps to address it.

Official Recognition and Action

In January 2016, a federal emergency was declared by President Obama, and the US Department of Health & Human Services (HHS) was designated as the lead federal agency for response and recovery efforts. The Centers for Disease Control and Prevention (CDC) played a crucial role in providing assistance and support. They coordinated effective health messaging, assessed lead exposure, provided guidance on blood lead screening, and linked community members to appropriate follow-up services. The CDC also established a federal advisory committee and enhanced the Childhood Lead Poisoning Prevention Program to address the crisis.

Long-Term Impact and Recovery

The Flint water crisis had a lasting impact on the community, with residents losing trust in their water supply even after improvements. As of April 2019, there were still an estimated 2,500 lead service pipes in place. However, through state and federal spending, Flint has secured a clean water source, distributed filters, and installed modern, safe copper pipes to most homes. The crisis also led to legal consequences, with several officials facing charges and civil lawsuits.
