Which Towns Have Faced Water Pollution Issues?

Water pollution is a pressing issue that affects towns and cities worldwide. While water is essential for life, it is also easily contaminated by toxic substances from farms, towns, factories, and other sources. In the United States, for example, agricultural pollution is the leading cause of contamination in rivers and streams, and unsafe drinking water affects millions of people annually. From Flint, Michigan, to Pensacola, Florida, and even California's picturesque Pasadena, polluted water poses a significant risk to public health and underscores the importance of addressing water quality issues.

Flint, Michigan: Lead from aging pipes poisoned the water supply

In 2014, Flint, Michigan, faced a major public health crisis when its drinking water supply was found to be contaminated with lead. The city's decision to switch its water source from Lake Huron, provided by the Detroit Water and Sewerage Department, to the Flint River was the primary cause of this disaster. This change was intended to reduce costs, but it ended up having devastating consequences for the residents of Flint.

The water from the Flint River was not adequately treated or tested, and it soon became apparent that it posed significant health and quality issues. For 18 months, residents of Flint endured foul-smelling, discoloured, and unpleasant-tasting water that was piped into their homes. Many people reported skin rashes, hair loss, and itchy skin, suspecting that their water was to blame.

The water crisis in Flint was a result of both environmental injustice and poor decision-making. Lead from aging pipes leached into the water supply due to the absence of corrosion inhibitors, putting nearly 100,000 residents at risk of lead exposure. Orthophosphate treatments were also omitted, leading to excessive pipe corrosion and high levels of lead and chloride in the water, which caused it to turn orange.

The situation was further exacerbated by the initial dismissal of residents' concerns by government officials. It wasn't until local groups and residents joined forces with the NRDC and the ACLU of Michigan to sue the city and state officials that their demands for safe drinking water were taken seriously. Even then, the EPA failed to act promptly, and it wasn't until January 2016 that Michigan Governor Rick Snyder declared a state of emergency in Genesee County, where Flint is located. President Barack Obama also declared a federal state of emergency, offering additional support from the Federal Emergency Management Agency and the Department of Homeland Security.

The crisis in Flint, Michigan, serves as a stark reminder that access to safe drinking water cannot be taken for granted. It also highlights the need for proper testing, treatment, and infrastructure maintenance to prevent similar disasters from occurring in the future.

Houston, Texas: 18 chemicals exceeded health guidelines, 3 were above the legal limit

Water pollution is a pressing issue in the United States, with many towns and cities facing contaminated water supplies. One notable example is Houston, Texas, where water pollution has been a significant concern for residents.

Houston, the fourth-largest city in the United States, sources its water from various sources, including the Trinity River, the San Jacinto Rivers, and Lake Houston. Between 2004 and 2007, Texas conducted an extensive water quality testing campaign on Houston's water supply, and the results were alarming. Out of the 22,083 water quality tests conducted, a staggering 18 chemicals were found to exceed federal and state health guidelines, far surpassing the national average of four. Even more concerning, three chemicals exceeded the legal health standards set by the Environmental Protection Agency (EPA), compared to the national average of 0.5 chemicals.

The water contamination in Houston has been attributed to various sources, including industrial pollution and natural occurrences. One of the primary concerns is the presence of "forever chemicals," a term used to describe perfluoroalkyl and polyfluoroalkyl substances (PFAS). These chemicals have been widely used in industrial and household applications since the 1940s and have been detected in Houston's tap water at levels above 40 parts per trillion. The health risks associated with PFAS exposure are significant, including cancer, low birth rates, birth defects, and damage to the liver and immune system.

The issue of water pollution in Houston has not gone unnoticed by the authorities and environmental groups. The Environmental Working Group (EWG) has been actively involved in monitoring and reporting on the city's water quality. In their latest drinking water quality report, the EWG found that while Houston's tap water met the federal health-based drinking water standards, it still fell short of the latest health guidelines. This discrepancy highlights the need for more stringent and updated legal limits for contaminants in tap water, which have not been revised in almost two decades.

The presence of pollutants in Houston's water supply has had a significant impact on the community. Residents have expressed concerns about the safety of their drinking water and the potential health risks associated with long-term exposure to contaminated water. The situation has also led to legal actions, with environmental groups suing the EPA for their perceived negligence in updating wastewater guidelines to prevent industrial pollution. Additionally, cities like Fort Worth and Dallas in Texas have rejected class-action settlements with chemical manufacturers, opting to file their own lawsuits to hold them accountable for polluting public drinking water.

Pensacola, Florida: 27 harmful contaminants were found, exceeding health guidelines

Towns with polluted water

• Pensacola, Florida: Ranked 12th in the US for toxic releases per square mile, Pensacola has a long history of pollution. In 2019, it was revealed that between 1997 and 2008, more than 400 households were permanently relocated from the Clarinda Triangle area due to concerns over dioxin and other pollutants. Underground plumes of toxic chemicals have contaminated Bayou Texar, leading to the closure of private irrigation wells. In 2022, EPA researchers observed visitors at Sanders Beach and Bayview Park to study coastal estuary recreational use and conducted sanitary surveys to examine water quality and identify sources of pollution. Pensacola Bay has been impacted by pollutants like heavy metals, microplastics, and toxic chemicals from sources such as roadway runoff and industrial waste. The drinking water in Pensacola has been reported to contain unhealthy levels of chemicals and contaminants, with some exceeding the limits set by the EPA.
• Flint, Michigan: Flint has faced a prolonged water crisis, with contaminated drinking water exposing thousands of children to toxic lead. In 2014, aging pipes caused lead to seep into the water system, effectively poisoning the community. In 2017, after three years of providing bottled water, officials declared the water safe, but concerns remain until all lead service pipes are replaced. The elevated lead levels have been linked to potential miscarriages, adverse infant health, and decreased reading levels among third-graders.
• Detroit, Michigan: Detroit has faced issues with unsafe levels of lead and copper in its water supply, impacting both residents and schools. In 2018, 57 out of 86 Detroit public schools had elevated levels of copper or lead, posing risks of permanent brain damage and learning disabilities in children. Additionally, thousands of Detroit residents have had their water shut off due to unpaid bills, a practice deemed "contrary to human rights" by the UN.
• Pittsburgh, Pennsylvania: Pittsburgh, an industrial town, has discovered unsafe levels of lead in its water supply, which can lead to serious health issues, especially in children.
• Houston, Texas: Texas conducted water quality tests on Houston's water supply from 2004 to 2007 and found 18 chemicals exceeding federal and state health guidelines, with three chemicals surpassing EPA legal health standards. Houston's water has also contained illegal levels of alpha particles, a form of radiation, and haloacetic acids from disinfection byproducts.
• San Diego, California: According to California's Department of Public Health, San Diego's drinking water system contained eight chemicals exceeding health guidelines and two chemicals, including trihalomethanes, that exceeded the EPA's legal limit.

Pensacola, Florida: Detailed Analysis

Pensacola, Florida, has faced significant challenges with polluted water, as evidenced by its ranking as 12th in the US for toxic releases per square mile. The issues stem from both historical and ongoing factors, with a report in 2019 revealing the relocation of hundreds of households due to concerns over dioxin and other pollutants. The contamination has impacted Bayou Texar, leading to the closure of irrigation wells and the contamination of sediments.

EPA researchers have been actively involved in studying and addressing the pollution in Pensacola. In 2022, they conducted observational surveys at Sanders Beach and Bayview Park to understand coastal estuary recreational use and water quality. Additionally, sanitary surveys were performed to investigate sources of fecal contamination and help identify and prioritize locations for water testing.

One of the significant concerns in Pensacola is the presence of toxic chemicals and pollutants in the water. This includes heavy metals, microplastics, and chemicals like 6-PPD quinone, which is highly toxic to game fish. These pollutants can enter the water through various sources, such as roadway runoff, industrial waste, and sewage.

The drinking water in Pensacola has also been a cause for concern. Reports indicate that the water contains unhealthy levels of chemicals and contaminants, with some even exceeding the limits set by the EPA. This has led to recommendations for residents to invest in water purifiers.

To address these issues, government officials and environmental regulators have implemented various measures. These include the development of air scrubbers, water filtration systems, monitoring and sampling programs, and restoration projects. However, there have been criticisms of a lack of transparency and effective regulation, with groups calling for stricter standards and increased protection of natural resources.

Modesto, California: Home to 212,000 people, the city has issues with uranium runoff

Modesto, California is home to 212,000 people and has experienced longstanding issues with uranium runoff, as well as other water contaminants. The city's water issues are closely related to its status as a large agricultural producer, with pesticides, fertilizers, and agricultural runoff adding contaminants such as nitrates to the water supply.

Uranium is a known human carcinogen, and while Modesto's water meets federal water safety standards, the presence of any uranium in drinking water is concerning. The federal legal limit for uranium is set at 30 micrograms per liter, which corresponds to 20 picocuries per liter (pCi/L) - a measure of radioactivity in water. Drinking water with this level of uranium would cause more than 4.6 cancer cases per 100,000 people. California has set a more stringent public health goal of 0.43 pCi/L for uranium, recognising that even small amounts can pose risks.

To address water contamination, Modesto has implemented treatments such as reverse osmosis and ion exchange to remove nitrates and PFAS chemicals. PFAS (per- and polyfluoroalkyl substances) are of particular concern due to their persistence in the environment and potential health effects, including cancer and thyroid disease. The Environmental Protection Agency (EPA) has designated certain areas around Modesto as superfund sites, indicating the need for extensive cleanup due to hazardous pollution.

The city's motto, "Water Wealth Contentment Health," reflects the importance of water in Modesto's agricultural legacy. However, in recent years, concerns about water safety have grown due to pesticide use, industrial runoff, spills, and pollutants. These issues are not unique to Modesto, as many towns across the western US struggle with similar challenges related to water quality and accessibility.

Puerto Rico: Residents turned to polluted streams after Hurricane Maria

In September 2017, Puerto Rico was struck by two major hurricanes, Irma and Maria, in quick succession. Hurricane Maria left the island's residents without power, with damaged homes, and without running water. In the aftermath of the storms, some residents lacked electricity, fresh food, and clean water for a prolonged period, and many had limited access to medical care.

In the immediate aftermath of Hurricane Maria, storm survivors collected spring water from the mountains for cooking and bathing, despite the threat of disease. With no running water in their homes, many people resorted to collecting supplies from mountain springs and streams.

The Federal Emergency Management Agency (FEMA) supplied 20,000 pallets of bottled water to Puerto Rico in the aftermath of Hurricane Maria. However, the water sat unused on an abandoned runway in Ceiba, leading to criticism of the government's disaster relief efforts.

The hurricane also exacerbated existing distrust in the municipal water supply. In Arecibo, a city on the northern coast of Puerto Rico, residents' distrust of the water supply stems from its proximity to a former battery processing facility. The site became a Superfund site in 2017, allowing for federal intervention to clean it up. However, shortly afterward, Hurricane Maria swept over it, raising concerns about water contamination. An Environmental Protection Agency (EPA) spokesman denied that the drinking water supply was contaminated during the storm, but local residents remain skeptical and continue to rely on alternative water sources.

Water quality expert Ben Bostick traveled to Puerto Rico to test water quality near three Superfund sites, including the battery plant. He collected over 100 samples from residents and waterways, testing for metals such as lead, arsenic, and uranium. Bostick found that, while pollution levels were surprisingly low, there was widespread distrust of the water supply and chronic problems with supply reliability.
