The Federal Water Pollution Control Act of 1948 was the first major U.S. law to address water pollution. Growing public awareness and concern for controlling water pollution led to sweeping amendments in 1972. As amended in 1972, the law became commonly known as the Clean Water Act (CWA).
How has the Clean Water Act changed over the years?
Over the years, many other laws have changed parts of the Clean Water Act. Title I of the Great Lakes Critical Programs Act of 1990, for example, put into place parts of the Great Lakes Water Quality Agreement of 1978, signed by the U.S. and Canada, where the two nations agreed to reduce certain toxic pollutants in the Great Lakes.
What is the purpose of the Clean Water Act?
Maintained existing requirements to set water quality standards for all contaminants in surface waters. Made it unlawful for any person to discharge any pollutant from a point source into navigable waters, unless a permit was obtained under its provisions.
What is the history of water treatment?
Turbidity was the main driving force between the earliest water treatments. Not much was known about micro organisms, or chemical contaminants. After 1500 BC, the Egyptians first discovered the principle of coagulation.
What was the first government regulation of public water?
This discovery led to governments starting to install municipal water filters (sand filters and chlorination), and hence the first government regulation of public water. In the 1890s America started building large sand filters to protect public health.

When did water treatment start?
The first water treatment facility was built in Scotland in 1804, and another in 1806 in Paris. These facilities purified water using a settling process first, to remove large sediments, and then passed the water through sand and charcoal filters.
Who was the first person to purify water?
As far back as 500 BC it's believed that the famous Greek scientist, Hippocrates invented the first early water filter… in the form of a cloth bag! This simple device was known as the 'Hippocratic sleeve'. The cloth acted like a sieve to filter out the impurities from the Greek aqueducts.

What are the steps of water treatment?
Today, the most common steps in water treatment used by community water systems (mainly surface water treatment) include: Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water.
Why is chlorine added to water?
After the water has been filtered, a disinfectant (for example, chlorine, chloramine) may be added in order to kill any remaining parasites, bacteria, and viruses, and to protect the water from germs when it is piped to homes and businesses.
What happens when chemicals are added to water?
Chemicals with a positive charge are added to the water. The positive charge of these chemicals neutralizes the negative charge of dirt and other dissolved particles in the water. When this occurs, the particles bind with the chemicals and form larger particles, called floc. Sedimentation.
What was the main driving force between the earliest water treatments?
Turbidity was the main driving force between the earliest water treatments. Not much was known about micro organisms, or chemical contaminants. After 1500 BC, the Egyptians first discovered the principle of coagulation. They applied the chemical alum for suspended particle settlement.
Why was water purified?
The major motive for water purification was better tasting drinking water, because people could not yet distinguish between foul and clean water. Turbidity was the main driving force between the earliest water treatments. Not much was known about micro organisms, or chemical contaminants.
Why did the 1890s use sand filters?
In the 1890s America started building large sand filters to protect public health. These turned out to be a success. Instead of slow sand filtration, rapid sand filtration was now applied. Filter capacity was improved by cleaning it with powerful jet steam. Subsequently, Dr. Fuller found that rapid sand filtration worked much better when it was preceded by coagulation and sedimentation techniques. Meanwhile, such waterborne illnesses as cholera and typhoid became less and less common as water chlorination won terrain throughout the world.
How did the Romans get water?
The Assyrians built the first structure that could carry water from one place to another in the 7th century BC. It was 10 meters high and 300 meters long, and carried the water 80 kilometres across a valley to Nineveh. Later, the Romans started building many of these structures. They named them aqueducts. In Latin, aqua means ‘water’, and ducere means ‘to lead’. Roman aqueducts were very sophisticated pieces of engineering that were powered entirely by gravity, and carried water over extremely large distances. They were applied specifically to supply water to the big cities and industrial areas of the Roman Empire. In the city of Rome alone more than 400 km of aqueduct were present, and it took over 500 years to complete all eleven of them. Most of the aqueducts were underground structures, to protect them in times of was and to prevent pollution. Together, they supplied Rome with over one million cubic meters of water on a daily basis. Today, aqueducts can still be found on some locations in France, Germany, Spain and Turkey. The United States have even taken up building aqueducts to supply the big cities with water again. Many of the techniques the Romans used in their aqueducts can be seen in modern-day sewers and water transport systems.
What was Archimedes' first water filter?
He invented the practice of sieving water, and obtained the first bag filter, which was called the ‘Hippocratic sleeve’. The main purpose of the bag was to trap sediments that caused bad tastes or odours. In 300-200 BC, Rome built its first aqueducts. Archimedes invented his water screw. Aqueducts.

What was the Flint water crisis?
One of the few bright spots of the Flint water crisis was the response of everyday citizens who, faced with the failure of city, state, and federal agencies to protect them, united to force the government to do its job. On the heels of the release of test results in the fall of 2015 showing elevated lead levels in Flint’s water—and its children— local residents joined with NRDC and other groups to petition the U.S. Environmental Protection Agency (EPA) to launch an immediate emergency federal response to the disaster. The EPA failed to act, which only spurred residents on.
