Nearly half of tap water in the United States contains at least one type of toxic synthetic organic fluoride, according to a survey released this week by the US Geological Survey.

The report mentioned that the United States Geological Survey collected samples from 716 locations, 45% of which had excessive levels of synthetic organic fluoride, and the pollution problem in urban areas was more serious than in rural areas. There are currently more than 12,000 synthetic organic fluorides, many of which cannot be detected by existing means, so the problem may be worse than the reports suggest, the agency said.

Synthetic organic fluorides have extraordinary persistence, accumulate in the human body and the environment, and cannot be broken down. They are called “permanent chemicals”. Exposure levels exceeding a certain level can cause negative health and environmental impacts, and may cause children’s Developmental problems, cancer, liver and kidney disease. Synthetic organic fluorides are widely used in the manufacture of products with anti-fouling, water-repellent, and oil-repellent properties, including fire extinguishing agents, non-stick pans, cleaning sprays, waterproof sporting goods, etc.

U.S. drinking water safety issues are frequent, the government is slow to act

In recent years, drinking water in the United States has frequently been exposed to safety issues. The problem of drinking water directly affects the lives of residents. Even so, the relevant government departments in the United States are still slow to act, and the problem of drinking water in many areas has not yet been resolved. In addition, there have been many water pollution incidents near US military bases.

In Benton Harbor, Michigan, USA, as early as 2018, the tap water of many residents’ homes was found to exceed the standard. However, the Michigan government will not issue a warning to residents until 2021. In Michigan, Flint, Detroit and other places also discovered the problem of excessive lead in tap water a few years ago. Lead poisoning can cause slow thinking in people, weakened learning ability in children, kidney damage, and insufficient brain development.

In April this year, the US Natural Resources Defense Council said that nearly 60 million people across the United States may be drinking lead-containing water without knowing it. Although the United States passed a law in 1986 prohibiting the installation of new lead pipes, there is no requirement to replace existing pipes. According to a survey released by the US Environmental Protection Agency, there are still 6 million to 10 million lead-containing water pipes in the United States.In order to effectively reduce the harm caused by water pollution, the following water filters can be installed at home.

water filter

A water filter is a device used to filter and purify tap water or other water sources. Its purpose is to remove suspended solids, particles, odors, odors, chemicals and microorganisms in water to provide cleaner and safer drinking water.

Water filters can use different filtration technologies and materials, including:

– Carbon Filter: Activated carbon filter effectively removes odors, tastes and organic compounds from water.

– Particle filter: The particle filter uses a fine pore size to filter out suspended solids and particles in the water, such as sediment, rust and particle pollutants.

– Fiber Filters: Fiber filters filter tiny particles and microorganisms such as bacteria, viruses and parasites through the pores of the fiber material.

– Reverse osmosis filter element: The reverse osmosis filter element is filtered through a semi-permeable membrane, which can effectively remove dissolved salts, heavy metals and harmful substances in water.

– UV Sterilizers: UV sterilizers use ultraviolet radiation to kill bacteria and viruses in water, thereby eliminating the risk of microbes.

The choice of water filter depends on the desired filtration effect and the characteristics of the water source. Household water filters can be installed on the faucet, and also come in a variety of designs such as jug style, inverted style and table style. Water filters for commercial and industrial use may require more complex systems and higher filtration capacity.

The use of water filters can provide cleaner, safer drinking water, reducing reliance on bottled water, while also being more environmentally friendly. However, water filters also require regular maintenance and filter replacement to ensure proper functioning and filtration.


Water Purification Filters

A water filter is a device used to remove impurities and pollutants from water to provide cleaner and safer drinking water. Water purification filters use different filtration technologies and filter materials to meet different water quality and filtration needs.

Common water purification filters include the following types:

– Activated Carbon Filter: Activated carbon has adsorption properties, which can effectively remove odors, tastes, chlorine, and organics from water.

– Particle filter: The particle filter removes suspended solids, particles, sediment and rust in the water through the pores in the filter medium.

– Reverse Osmosis Filters: Reverse osmosis filters utilize semi-permeable membranes to filter ions, dissolved substances, bacteria and viruses from water, providing highly pure water quality.

– UV sterilizers: UV sterilizers use ultraviolet radiation to kill bacteria, viruses, and other microorganisms in water to provide a germicidal effect.

– Ion exchanger: The ion exchanger removes ions in water, such as calcium, magnesium, iron and lead, etc., through exchange resins.

– Nano-filter: Nano-filter has a small pore size, which can filter tiny particles and microorganisms, providing high-efficiency filtration.

The choice of water purification filter should be based on water quality, filtration needs and budget. Some water purification filters use a combination of multiple filtration technologies to provide a more comprehensive water purification effect. Regular filter replacement is the key to maintaining filtration efficiency and water quality, and the frequency of filter replacement depends on water quality and usage.

Water purification filters are an effective way to improve the quality of drinking water by removing harmful substances and impurities.


Various pollution incidents occurred one after another near the US military base

In addition to historical problems caused by outdated equipment, some new pollution incidents have occurred one after another in recent years, especially near US military bases. In 2021, a water pollution incident occurred at a US Air Force base in Arizona, USA. The fire-fighting foam materials used in the base contained excessive levels of synthetic organic fluorides, causing about 1,600 households and some nearby businesses to pollute the water. One resident suffered from severe kidney disease.

According to data released by the U.S. Department of Defense in 2022, the levels of synthetic organic fluoride in drinking water near several U.S. military bases in Washington, Pennsylvania, Florida, and Michigan exceeded the standard. For far too long, service members and those living near military installations have been victims of Pentagon inaction, according to staffers at the Environmental Working Group, a U.S. nonprofit.
