Consequences Of Consuming Polluted Water: A Health Hazard

Water is an essential resource for all life on Earth. However, water pollution is a serious issue that is endangering the health of humans and the environment. If a water source becomes contaminated, it can lead to various health issues in humans, such as gastrointestinal illnesses, nervous system damage, reproductive issues, and chronic diseases such as cancer. Polluted water can also cause waterborne diseases such as typhoid fever, cholera, hepatitis, and diarrhea, which can be life-threatening. The contamination of drinking water can occur due to natural sources, such as high levels of arsenic or other heavy metals in groundwater, or human activities, like industrial waste and agricultural runoff. With increasing water scarcity, population growth, and the finite nature of our drinkable water sources, addressing water pollution and ensuring access to safe drinking water is becoming an increasingly critical challenge.

Characteristics and Values of Drinking Polluted Water

Waterborne diseases

Some of the most common waterborne diseases include:

• Cholera: Spread through contaminated water, cholera causes severe dehydration and diarrhea. It can be fatal within days or even hours of exposure to the bacteria.
• Typhoid: While rare in industrialized countries, typhoid fever is common in extremely poor parts of the world, with an estimated 20 million people suffering from the illness each year. It is spread through contaminated food, unsafe water, and poor sanitation.
• Diarrhea: Diarrhea is a central symptom of many waterborne diseases and is the second-leading cause of death for children under five years old.
• Hepatitis: Hepatitis can be severe in people with weakened immune systems, such as infants and the elderly, and can sometimes be fatal in people with severely compromised immune systems.
• Giardia: Caused by a parasite, giardia is often found in ponds and streams but can also contaminate a town's water supply. It typically clears up within a few weeks, but those exposed may experience intestinal problems for years.

To prevent waterborne diseases, it is important to practice safe sanitation and hygiene and have access to clean water. Vaccines are also available for some waterborne diseases, such as typhoid.

Cancer and cardiovascular issues

Drinking polluted water can have severe health consequences, including cancer and cardiovascular issues. Water pollution is a widespread problem, with nearly half of rivers and streams and over one-third of lakes being contaminated and unfit for human use. This contamination can occur due to various sources, including industrial waste, agricultural runoff, and sewage.

One of the most pressing concerns regarding polluted drinking water is its potential to cause cancer. Certain contaminants, such as heavy metals, arsenic, uranium, radium, and disinfection byproducts, are known carcinogens. For example, a 2020 study linked pesticides in Nebraska groundwater to estrogen-related cancers. Similarly, high levels of toxic byproducts, such as trihalomethanes (TTHMs), resulting from the interaction between disinfectants and organic pollutants, have been associated with increased risks of bladder and colorectal cancer.

Moreover, polluted drinking water can also contribute to cardiovascular conditions. Arsenic exposure, even at low to moderate levels, has been linked to cardiovascular diseases, as evidenced by studies in Bangladesh. Additionally, uranium in drinking water poses a significant threat to human health, potentially leading to cardiovascular issues, as well as other health problems.

The consumption of polluted water can also lead to gastrointestinal illnesses, nervous system disorders, reproductive issues, and chronic diseases. It is worth noting that the effects of some drinking water contaminants are not yet fully understood, and further research is needed to comprehend the full scope of the health risks associated with drinking polluted water.

With the finite availability of clean drinking water and the increasing demand for freshwater, it is crucial to address water pollution and its impact on human health. The contamination of water sources poses a severe threat to public health, and immediate action is necessary to curb this crisis.

Gastrointestinal illnesses

One of the leading causes of gastrointestinal illnesses in polluted water is sewage contamination. Sewage-contaminated water can contain harmful bacteria, viruses, and parasites that can cause infections and gastrointestinal problems. For example, Campylobacteriosis, caused by the bacterium Campylobacter, is the most common diarrhoeal illness in the United States. It can lead to bloody diarrhoea, cramping, abdominal pain, nausea, vomiting, and fever. Another example is Giardiasis, caused by the parasite Giardia intestinalis, which is one of the most common waterborne diseases in the United States. It can cause diarrhoea, loose stools, stomach cramps, and an upset stomach.

Viral gastroenteritis, also known as the "stomach flu," is another common gastrointestinal illness caused by drinking polluted water. It is an infection caused by viruses such as rotaviruses, adenoviruses, and caliciviruses. Symptoms of viral gastroenteritis include watery diarrhoea, vomiting, headache, fever, and abdominal cramps. These symptoms can last for 1 to 10 days, depending on the virus involved, and can be particularly severe for infants, young children, the elderly, and those with compromised immune systems.

In addition to bacteria and viruses, parasites can also cause gastrointestinal illnesses in polluted water. For example, Cryptosporidium parvum is a microscopic parasite that can cause diarrhoea and abdominal pain. Salmonella is another common bacterial contaminant found in polluted water, leading to diarrhoea, fever, and abdominal cramps.

Furthermore, chemical pollutants in water, such as pesticides, fertilizers, and heavy metals, can also contribute to gastrointestinal illnesses. While the impact of ingesting these chemicals may not be immediately apparent, long-term exposure can lead to serious health issues, including gastrointestinal problems.

Nervous system damage

Drinking polluted water can have severe health consequences. It can lead to waterborne diseases, gastrointestinal illnesses, nervous system damage, and reproductive issues. It can also cause chronic diseases, such as cancer, and increase the risk of cardiovascular conditions.

The nervous system, including the central nervous system (CNS) and the peripheral nervous system, is responsible for transmitting signals between different parts of the body and plays a crucial role in various bodily functions. When pollutants are ingested through drinking water, they can interfere with the normal functioning of the nervous system, leading to a range of issues.

One of the critical aspects of nervous system damage is the potential for neurotoxicity. Certain contaminants, such as arsenic and cadmium, are known to have neurotoxic effects. These substances can accumulate in the body over time, leading to long-term damage to the nervous system. This damage can manifest in various ways, including cognitive impairments, behavioral changes, and even neurodegenerative disorders later in life.

Additionally, drinking polluted water can also impact the developing nervous system, especially in children. Exposure to contaminants during critical stages of growth and development can have detrimental effects on brain function and increase the risk of neurological disorders. Regulatory guidelines play a vital role in safeguarding drinking water quality, but they may not always capture the health hazards of chronic low-dose exposure to certain contaminants.

Reproductive issues

Drinking polluted water can have detrimental effects on reproductive health. The United Nations (UN) estimates that 2.2 billion people lacked access to safely managed drinking water services in 2022. This lack of access to clean water is harming the reproductive health of many people in the US, particularly in Flint, Michigan, and California.

Water pollution can occur when contaminants such as pesticides, fertilizers, heavy metals, and waste from landfills and septic systems make their way into water sources, including groundwater and surface water. These contaminants can have harmful effects on reproductive health. For example, exposure to high doses of chemicals found in polluted water can lead to reproductive issues such as organ damage and developmental problems.

Additionally, certain chemicals commonly found in polluted water, such as atrazine, disinfection byproducts, arsenic, and perchlorate, are known to adversely affect reproduction, fertility, and pregnancy outcomes. The effects of drinking water contaminants on reproductive health can vary depending on factors such as the type of contaminant, its concentration in the water, individual susceptibility, and the duration of exposure.

It is important to note that the full scope of the effects of drinking water contaminants on reproductive health may not yet be fully understood. However, it is clear that access to clean, potable water is critical for maintaining reproductive health and overall well-being. Providing access to safe drinking water is an essential government service and a basic public health necessity.
