Water is polluted throughout the entire production chain. Agriculture is one of the biggest polluters, using up to 70% of the world's freshwater and releasing over 80% of wastewater without adequate treatment. Construction is another major polluter, with 40% of freshwater pollution attributed to buildings. Industrial activity also leads to the release of pollutants to water, including total organic carbon (TOC) and compounds that contain nutrients such as nitrogen and phosphorous.

What You'll Learn
Agriculture
Water is polluted throughout the entire production chain. It starts with the runoff of fertilisers from cotton plantations into nearby lakes and rivers, continues through the dyeing of clothes with toxic chemicals and ends with the use of the product when washing releases fibres and dyes into the wastewater. In addition, the fashion industry has a huge water footprint, consuming around 79 billion cubic metres of water per year, which would be enough to fill 32 million Olympic swimming pools. When you break it down, it takes approximately 7,000 litres of water to produce one pair of jeans. The same amount a person drinks in five to six years.
Industrial activity leads to the release of pollutants to water, including total organic carbon (TOC) and compounds that contain nutrients such as nitrogen and phosphorous, which can cause eutrophication. The EPA has once again refused to change the limits for several dirty industries. Guidelines for 40 of the 59 industries that the agency regulates were updated 30 or more years ago. Several of these industries, including oil refining, plastics manufacturing, and fertilisers, have limits that are nearly 40 years old.

Construction
The construction industry is not often on the environmentalists' radar but although it is often overlooked, 40% of freshwater pollution can be attributed to buildings. Every single building has an impact on the environment from the materials we choose, to the technologies we use, and the sites we build. For example, it takes more than 5,100 litres of water just to produce a single tonne of cement, and a staggering 235,000 litres to produce a tonne of steel.

Industrial activity leads to the release of pollutants to water, including total organic carbon (TOC) and compounds that contain nutrients such as nitrogen and phosphorous, which can cause eutrophication. Globally, over 80% of wastewater is released to the environment without adequate treatment, polluting rivers, lakes and oceans. In order to gain an insight into the issue, we have summarised the industries that contribute the most to water pollution.
Agriculture uses up to 70% of the world's freshwater (20% is used by industry) and is one of its biggest polluters. The most water-intensive crops are wheat, maize, rice, cotton and sugarcane. A large share of the water is also used to grow bioenergy crops such as sugar cane and rapeseed. These are then turned into ethanol or biodiesel and used as biofuels. This is another reason to accelerate the transition to renewable energy sources like wind and solar.

Oil refining
The EPA has refused to change the limits for several dirty industries, including oil refining, plastics manufacturing, and fertilizers. Guidelines for 40 of the 59 industries that the agency regulates were updated 30 or more years ago. Oil refining has limits that are nearly 40 years old.
Water pollution is a major environmental issue that affects rivers, lakes, and oceans. Over 80% of wastewater is released into the environment without adequate treatment. Oil refining is a dirty industry that releases pollutants into water, including total organic carbon (TOC) and compounds that contain nutrients such as nitrogen and phosphorous. These pollutants can cause eutrophication, which is a process where excess nutrients cause algal blooms and oxygen depletion in water bodies.

Plastics manufacturing
The plastics manufacturing industry is one of the dirtiest and oldest industries that pollute water. Water pollution is a major issue that needs to be addressed. The EPA has refused to change the limits for several dirty industries, including plastics manufacturing, and fertilizers, which have limits that are nearly 40 years old.
The plastics manufacturing industry is a major source of water pollution because it releases pollutants to water, including total organic carbon (TOC) and compounds that contain nutrients such as nitrogen and phosphorous. These pollutants can cause eutrophication and harm aquatic life.
The plastics manufacturing industry is also a major source of water pollution because it uses a large amount of water in its production process. Water is polluted throughout the entire production chain, starting with the runoff of fertilisers from cotton plantations into nearby lakes and rivers, and ending with the use of the product when washing releases fibres and dyes into the wastewater.
The plastics manufacturing industry is also a major source of water pollution because it releases toxic chemicals into the water. These toxic chemicals can cause harm to aquatic life and human health.
The plastics manufacturing industry is also a major source of water pollution because it uses a large amount of energy in its production process. This energy use can cause water pollution through the release of pollutants and toxic chemicals.
