Summary
Chlorine and chloramine, common water disinfectants, pose health risks and environmental concerns. Here’s what you need to know:
- Chlorine basics: Used to kill pathogens in water, but can cause respiratory, skin, eye, and gastrointestinal issues.
- Chloramine introduction: Formed when ammonia is added to chlorinated water, offering stability but also health risks.
- Historical context: Chlorine’s use dates back to the early 20th century, with chloramine introduced as a more stable alternative.
Water is the most fundamental living thing on earth, but what people don’t realise is that the water they consume may be contaminated with contaminants like chlorine and chloramine that are unhealthy for them.
What is Chlorine?
The chemical compound chlorine is a very reactive compound that is used in water treatment to kill bacteria, viruses, and other pathogens. In water we add chlorine to make it safe for drinking, but in high doses the contaminant can have toxic consequences for humans as well.
The water treatment system was first pumped with chlorine at the beginning of the 20th century and became quickly the main disinfectant in water-treatment plants. Chlorine is effective as a disinfectant, but it’s also been linked to some health risks, including respiratory problems, skin irritation, eye irritation and gastrointestinal disorders.
What is Chloramine?

Chloramine is a chemical created when ammonia is mixed with chlorine-treated water. Chloramine is an auxiliary disinfectant for water treatment that is often preferred to chlorine as it is stable and does not evaporate as quickly as chlorine.
Chloramine was added to water treatment as a second disinfectant to counter some of the issues with chlorine. Chloramine is more permanent and effective than chlorine as a disinfectant, but has also been shown to be harmful to the health: respiratory symptoms, skin irritation, eye irritation and gastrointestinal disorders.
The History of Chlorine and Chloramine in Water Treatment
Chlorine and chloramine in water treatment have a long history – chlorine was first used to treat water, so it could be drank. Originally chlorine was the primary disinfectant of water treatment but as the stability and health hazards of chloramine became a problem, it was developed as a secondary disinfectant. Chloramine is now in many water treatment plants as a more durable alternative to chlorine and a safer, more efficient disinfectant.
The Health Risks of Chlorine and Chloramine in Our Water
The presence of chlorine and chloramine in our water can have adverse effects on human health, especially when consumed in large amounts. Some of the potential health risks associated with consuming water contaminated with chlorine and chloramine include:
- Respiratory problems: Chlorine and chloramine can cause respiratory problems, such as coughing, wheezing, and shortness of breath, especially in people with pre-existing respiratory conditions, such as asthma.
- Skin irritation: Chlorine and chloramine can cause skin irritation, itching, and rashes, especially in people with sensitive skin.
- Eye irritation: Chlorine and chloramine can cause eye irritation, redness, and itching, especially in people who are sensitive to these chemicals.
- Gastrointestinal problems: Chlorine and chloramine can cause gastrointestinal problems, such as nausea, vomiting, and diarrhea, especially in people who are sensitive to these chemicals.
Consuming water contaminated with high levels of chlorine or chloramine can also increase the risk of more serious health problems, such as cancer, reproductive problems, and developmental problems in children.
The Importance of Regular Water Testing
Regular water testing is essential to ensure that the levels of chlorine and chloramine in our water are safe and within acceptable limits. Water testing can be performed by water treatment plants, or by independent laboratories, and can help to identify any potential problems with the water supply, such as elevated levels of chlorine or chloramine. Regular water testing can help to ensure that the water we drink is safe and of high quality, and can help to prevent potential health problems associated with exposure to these chemicals.
The Impact of Chlorine and Chloramine on the Environment
The presence of chlorine and chloramine in our water can also have adverse effects on the environment, especially when large amounts of these chemicals are released into the environment through wastewater discharge. Some of the potential impacts of chlorine and chloramine on the environment include:
- Harm to aquatic life: Chlorine and chloramine can harm aquatic life, such as fish, frogs, and other aquatic animals, especially in high concentrations.
- Water pollution: Chlorine and chloramine can contribute to water pollution, especially when released into the environment through wastewater discharge.
- Soil contamination: Chlorine and chloramine can contaminate soil, leading to reduced soil quality and harm to plants and other vegetation.
The Benefits of Clean and Safe Water
Clean and safe water is essential for human health and well-being. Consuming water that is free of harmful chemicals, such as chlorine and chloramine, can help to reduce the risk of health problems and improve overall health and well-being. Clean and safe water can also benefit the environment by reducing water pollution and protecting aquatic life.
The Role of Water Treatment Plants in Regulating Chlorine and Chloramine Levels
Water treatment plants play a crucial role in regulating the levels of chlorine and chloramine in our water. These plants are responsible for monitoring and controlling the levels of these chemicals in the water supply, and for ensuring that the water is safe for drinking. They use sophisticated equipment and techniques to measure the levels of chlorine and chloramine in the water, and to adjust the levels as needed to maintain the safety and quality of the water.
Reducing Exposure to Chlorine and Chloramine in Our Water
There are several steps that can be taken to reduce exposure to chlorine and chloramine in our water, including:
- Installing a water filtration system: Installing a water filtration system, such as a reverse osmosis system or activated carbon filter, can help to reduce the levels of chlorine and chloramine in your water. These systems work by removing harmful chemicals, such as chlorine and chloramine, from your water supply.
- Using alternative sources of water: Using alternative sources of water, such as spring water or purified water, can help to reduce exposure to chlorine and chloramine in your water.
- Advocating for change: Advocate for change by contacting your local government officials and expressing your concerns about the presence of chlorine and chloramine in your water supply. You can also support organizations that work to improve water quality and reduce the presence of harmful chemicals in our water.
What are the Alternatives in Water Disinfection Methods?
While chlorine and chloramine are widely used in water treatment, there are alternative water disinfection methods that can be used to make water safe for drinking. These methods include ultraviolet (UV) light disinfection, ozone disinfection, and ceramic filtration. These alternative disinfection methods can help to reduce the presence of harmful chemicals in our water, and can provide a more natural and environmentally friendly approach to water treatment.
