Water filtering is a very important process because it is very hard to determine the quality of Tap water. Most of the times tap water is filtered in a facility before it reaches the user. but the problem with this s that they never test the water wen it goes though the municipal feed lines which most of the times pollute the water even more. The water while it is being distributed it can encounter microorganisms bacteria and viruses that is why it is important to filter your water before drinking. Studies also say that the contaminants of the water can accumulate in the body which in theory could lead humans to suffer form a weaker immune system, cancer, and thyroid hormone disruption.

Sanitation is one of the most important factors to living a healthy life. Unicef states "Two Billion people still do not have basic sanitation services. while 673 million people practice'Open Defection'." Not having santitation put everyine in risk of deaseases specialy young kids. Faecal Matter contaminate food and make the general place smell and attract insects that could have deseases. Even with public toilet water contamination still exits, these don't stop that.

Poor sanitation puts children at risk of childhood diseases and malnutrition that can impact their overall development, learning and, later in life, economic opportunities. While some parts of the world have improved access to sanitation, millions of children in poor and rural areas have been left behind.

Lack of sanitation can be a barrier to individual prosperity and sustainable development. When children, especially girls, cannot access private and decent sanitation facilities in their schools and learning environments, the right to education is threatened. As adults, wage earners who miss work due to illness may find themselves in financial peril. And when health systems become overwhelmed and productivity levels fall, entire economies suffer.

Without basic sanitation services, people have no choice but to use inadequate communal latrines or to practise open defecation, posing a risk to health and livelihoods.

Even in communities with toilets, waste containment may not be adequate. If they are difficult to clean or not designed or maintained to safely contain, transport and treat excreta, for example, waste might come into contact with people and the environment. These factors make sustainable development nearly impossible.

Open defecation

The practice of defecating in the open (such as in fields, bushes, or by bodies of water) can be devastating for public health.

Exposed faecal matter contaminates food, water and the environment, and can spread serious diseases, such as cholera. Coupled with poor hygiene practices, exposure to faecal matter remains a leading cause of child mortality, morbidity, undernutrition and stunting, and can negatively impact a child's cognitive development.

Harmful to community health and well-being, open defecation can also undermine individual dignity and safety - especially for girls and women. When forced to travel greater distances from home to reach adequate hygiene facilities, girls are women are put at greater risk of violence.

Water filtering is a method used to filter out toxic chemicals or harmful bacteria from water. the purpose of this process is to provide us with clean water that can be consumed. The process reduces the risk of consuming harmful things for the human body. the water then can be used directly in households or industrial applications.

What is SDG 6, Sdg s6 knows as Clean water and sanitation is one ove first global goal created by the United Nations. THe worlds progress in this specific goal is not sufficent. More change needs to happen to make water reach parts that aren't develeped. According to The un website water has reached to twice the rate of human population. They state the one third of the population still lack of washing their hands with soap.

# data[].attributes.attachment_link.readable_text
Billions of people still lack access to safe water, sanitation, and hygiene, despite improvement in the provision of these basic services. Water scarcity is a growing problem in many parts of the world, and conflicts and climate change are exacerbating the issue. In addition, water pollution is a significant challenge which affects both human health and the environment in many countries. Achieving universal coverage by 2030 will require a 6-fold increase in current global rates of progress on drinking water, a 5-fold increase for sanitation, and an 8-fold increase for hygiene. Boosting infrastructure investment, improving cross-sectoral coordination, and addressing climate change is key to getting SDG6 back on track.

Targets 6.1 and 6.2: Despite progress, 2.2 billion people still lacked safely managed drinking water services, 3.4 billion lacked safely managed sanitation services, and 1.9 billion lacked basic hygiene services in 2022. While the majority live in rural areas, the unserved population is decreasing in rural areas and stagnating or increasing in urban areas. Achieving universal coverage by 2030 will require an increase of 5 to 8 times the current rate.

Target 6.3: An estimated 58% of wastewater generated by households was safely treated in 2022, based on data from 140 countries and territories. Trends for domestic wastewater suggest that little, if any, progress is being made towards the target of halving the proportion of unsafe discharges by 2030.

Target 6.4: Water use efficiency rose from $17.4/m3 in 2015 to $18.9/m3 worldwide in 2020, which represents a 9% efficiency increase. Around 57% of countries presented a water use efficiency equivalent to $20/m3 or less in 2020, compared to 58% in 2015.

Target 6.4: At the global level, water stress remains at a safe level of 18.2% in 2020, but this figure masks vast regional variations and indicates a 1.2% increase from 2015 to 2020. In 2020, water stress levels ranged from high in Southern Asia and Central Asia to critical in Northern Africa. The situation in Western Asia and Northern Africa is particularly concerning since it registered an 18% increase in water stress levels from 2015 to 2020.

Target 6.5: One in two countries still lacks effective frameworks for sustainable water management. A lack of cross-sector coordination over water use, between agriculture, industry, energy production, and household supply, threatens the achievement of several SDGs, including those on food, energy, and life on land. While progress has been made globally since 2015-from 49/100 in 2017 to 54/100 in 2020-the rate of implementation needs to double to achieve the target.

Target 6.5: Data from 2017 and 2020 show that only 32 out of 153 countries that share transboundary rivers, lakes, and aquifers have 90% or more of those waters covered by operational arrangements.

Target 6.6: The extent of surface water bodies, including lakes, rivers, and reservoirs, is rapidly changing across the entire planet, with one in five river basins experiencing high (i.e. above natural) fluctuations in surface water during the last 5 years.

Target 6.a: ODA disbursements to the water sector decreased between 2015 and 2021 from $9.1 billion to $7.8 billion, a decrease of 15%. Total ODA commitments to the water sector have also reduced by 13% from $10.8 billion in 2015 to $9.4 billion in 2021. Commitments peaked at $13 billion in 2017 and have decreased every year since.

Target 6.b: Since 2016, the percentage of countries having procedures for local community participation defined in law or policy has remained high (over 70%) for both rural drinking water and for water resources management. However, the percentage of countries with high levels of participation remains consistently low (under 40%).

What do we consider to be potable water?

# data[].attributes.body
Potable water refers to water that is adequate for human consumption in the long term. Any water that causes health issues or is polluted is non-potable. There are four recognised levels of water purity within potable water. Feed water is what a large part of the developing world relies on, water that is barely clean enough to be consumed with no lasting detriments, but may often be contaminated with visible impurities or not be fully colourless. Carbon filtration and reverse osmosis make up primary grade water, and the other two types are ultra pure waters that are non plausible as a widespread solution. The world has to focus on universal access of barely potable water for everyone before we concern ourselves with mineral concentrations or purity levels

# data[].attributes.attachment_link.readable_text
There are four levels of water purity recognised in the water purification industry, each of which are used for specific applications in laboratories.

The quality of water is defined through a series of measurements of conductivity (µS/cm) or resistivity MΩ-cm), Total Organic Carbon (TOC) in parts per billion (ppb), and bacterial count (CFU/ml).

Here we explain the four types of water used in laboratories, as well as the processes and properties of each type.

Types of Laboratory Water

1. Feed Water

Feed water is also referred to as raw or potable water, and the quality of it is dependent on its source. Whilst deep water is naturally filtered by layers of rock and soil, water from surface sources like lakes and reservoirs is at risk of environmental contamination.

Raw or feed water is typically identified by measuring its colour, odour and turbidity. You can also look for chemical characteristics like pH and hardness, as well as bacteriological characteristics.

Some of the most significant contaminants of feed water include dissolved ions, minerals, microorganisms and organic compounds.

Feed water should always be tested, and have appropriate pre-treatment measures conducted, to ensure that the quality is sufficient enough to not damage the downstream purification technology.

The most common type of pre-treatment are depth-filters. This process consists of raw water passing through a series of winding fibres, which attract and trap impurities. Carbon is also used to bind chlorine ions, because if they're not removed, they will cause rapid deterioration of reverse osmosis (RO) membranes.

Another step commonly taken is the installation of a water softener, reducing the hardness level of water before it reaches the RO membrane; hard water causing scaling of the RO membrane and reduces its lifespan.

2. Primary Grade Water (Type 3)

Primary grade pure water (Type 3) uses carbon filtration and RO technology, and is the most cost-effective way to reduce water contaminants.

Removing up to 99% of feed water contaminants, RO sees water flow from a less concentrated solution through a semipermeable membrane to a more concentrated solution. By applying external pressure to the more concentrated side, the osmotic flow is reversed, which forces the water through the membrane, and deposits the impurities on the surface.

RO technology applies diffusion as opposed to separation, rejecting particles with a higher molecular weight. Feed water temperature, pressure, and the physical condition of the RO membrane are all parameters that affect rejection rates. Therefore, whilst rejection rates are variable, they tend to increase as the ionic charge and size of the molecule increases. For this reason, RO water can't be specifically classified.

RO water is most commonly used at the starting point for many applications in laboratories, including feeding glassware washing machines and autoclaves. It can also be used as a pre-treatment for ultrapure water systems, or anything that's considered non-critical.

3. General Laboratory Grade Water (Type 2)

Also known as general laboratory grade water, Type 2 water is produced through a combination of reverse osmosis, and an additional technology such as ion exchange or electrical ion exchange (EDI).

Deionisation, or ion exchange, removes ions from RO water by using synthetic resins. Chemical reactions occur as the water passes through the ion exchange beads, resulting in the removal of ions. This process is continued until all unwanted ions are replaced by hydrogen and hydroxyl ions, which form pure water once combined.

EDI is an active purification technology that combines electrodialysis with ion exchange. Water is passed between an anion permeable membrane and a cation permeable membrane within an EDI cell. The cell chamber contains loosely packed ion exchange resin. Ions are then attracted to the oppositely charged electrode, but they're flushed away before they're able to reach it, which means they're removed from the water.

Together, these two processes create Type 2 water, which has a resistivity of 1-15MΩ-cm, making it suitable for general applications such as buffer and media production, general chemistry and spectrophotometry.

4. Ultrapure Water (Type 1)

With a resistivity of 18.2 MΩ-cm at 25°C, ultrapure (Type 1) water is a requirement for analytical laboratories. Flow cytometry, pyrogen sensitive applications, and cell and tissue culture are all typical applications for Type 1 water.

Water with this type of resistivity can still contain organic contaminants, endotoxins and nucleases which don't impact on resistivity values, so other technologies are required to eliminate them.

Equipment that produces Type 1 water is often referred to as a "polisher", and can be fed from a localised reverse osmosis system, or a centralised ring main.

Bacteria and organic levels are maintained lowly, through a dual wavelength ultraviolet (UV) light (185nm and 254nm). The water flows through a vessel containing a UV light, and as it passes through, the light damages any genetic molecules that are needed for reproductive functions. This damage prevents the microorganism from multiplying or replicating, which means no infection can occur.

An ultrafilter (UF) can also be used to produce DNase/RNase free water. By using size exclusion, ultrafiltration removes particles and macromolecules, and is sometimes charged to attract contaminants. This technology is employed at the end of the system, to ensure the near-total removal of macromolecular impurities.
Each type of water must go through various processes and technologies to achieve a certain standard of purity. The level of purity then reflects what they can be used for in laboratories. For that reason, it's important to be able to distinguish between the four types of water, so you can understand how they are utilised in laboratories.

Again, our SDG needs the most progress in Africa, because many of these communities have no way to purify their water and also pollute it themselves. However more common than death by thirst is death by disease due to not having a continuous source of water to sanitise. The environments without sanitation allow diseases to thrive and take many lives, especially children and elders. In Chad, there is a 1 in 10 chance that a certain death was caused by polluted drinking water

# data[].attributes.attachment_link.readable_text
One in four people does not have access to safe water. In low-income countries, unsafe water accounts for six out of every 100 deaths.

People across the globe observe March 22 as World Water Day - designated by the United Nations to raise awareness of the two billion people living without access to safe water. The theme this year is "Groundwater: making the invisible visible".

Groundwater is the water found below the Earth's surface and is the largest source of fresh water on earth.

Safe and readily available water is important for public health. Polluted water is linked to the transmission of many diseases including cholera, diarrhoea, dysentery, hepatitis A, typhoid and polio.

According to the World Health Organization (WHO), diarrhoeal diseases resulted in the deaths of some 1.5 million people in 2019, making this the eighth-highest cause of death globally, particularly among lower-income groups.

Higher death rates in low-income countries

Globally, at least two billion people use a drinking water source contaminated with faeces.

In 2019, the share of annual deaths attributed to unsafe water across the world ranged from a high of 10.1 percent in Chad - about 100 in 1,000 - to about 0.3 percent on average in the Americas to less than 0.02 percent across most of Europe, according to the Global Burden of Disease Collaborative Network.

In low-income countries, unsafe water sources account for the deaths of six out of every 100 people.

Which countries have the safest drinking water?

In 2020, about three-quarters (74 percent) of the world's population had access to clean drinking water. One in four people does not have access to a safely managed water source.

In the least-developed countries, 22 percent of healthcare facilities have no water service, 21 percent have no sanitation service, and 22 percent have no waste management service. Most are in sub-Saharan Africa.

Ten countries - eight in Africa and two in Asia - have less than a 20 percent share of the population with access to safely managed drinking water. The lowest in share percentages are Chad (5.6 percent), the Central African Republic (6.2 percent), Sierra Leone (10.6 percent), Rwanda (12.1 percent) and Ethiopia (12.6 percent).

The countries with 100 percent access to safe drinking water include Greece, Iceland, Kuwait, Lichtenstein, Malta, Monaco, New Zealand, San Marino and Singapore.

How to protect yourself from waterborne diseases

Some main precautions that can be taken to protect yourself and your family from waterborne diseases are recommended by the United States Centers for Disease Control and Prevention (CDC), including:

Practice good personal hygiene. Make sure to always wash your hands before preparing or eating food and after visiting the toilet, cleaning a child, or handling animals.

Maintain and clean water facilities. Clean, disinfect, and maintain all devices that use water. Water from private water supplies should be routinely tested twice a year.

Drink properly treated water. Treat drinking water before using it by boiling, adding disinfectants, or filtering.

Take food safety precautions. Eat thoroughly cooked food that is served piping hot, fruits that you can peel yourself and pasteurised dairy products.

" By 2030, expand international cooperation and capacity-building support to developing countries in water- and sanitation-related activities and programmes, including water harvesting, desalination, water efficiency, wastewater treatment, recycling and reuse technologies "

- 2030 Agenda for Sustainable Development

What and why?

Although the implementation of SDG 6 is expected to generate benefits that widely exceed the costs of doing so, some hundreds of billions of dollars still need to be raised for the purpose. Needs are greatest in developing countries, calling for an increased mobilization of domestic funds, but also a significant scaling-up of external support. In this regard, target 6.a seeks to expand international cooperation and capacity-building support to developing countries. International cooperation refers to external aid in the form of grants or loans, including official development assistance (ODA). Capacity-building includes strengthening the skills, competencies and abilities in developing countries in regard to water governance and management.

Creating an enabling environment is an essential first step for succeeding with the implementation of any management response. The "means of implementation" targets 6.a and 6.b are complementary to the dedicated means of implementation goal (SDG 17) and its 19 targets, which focus on finance, technology, capacity-building, trade and systemic issues.

Access to safe drinking water. There are currently more than 1000 million people in the world that lacks access to an easily accessible and safe water source, such as a connection to water mains or a protected well. Instead, water access is limited or available through unprotected sources. The target, under the Millennium Development Goals, is to halve, by 2015, the proportion of people without sustainable access to safe drinking water and sanitation.

Percentages are a very important form of statistic that is used to measure our SDG, as the objective is universal or 100% access to clean water sources. Statistics like percentage of people who have access to sanitation systems or potable water are important in quantifying the progress we make toward this goal. Also, figures such as number of hospitals with water and soap sanitation and number of pollution related deaths are important. Our SDG can be measured by region, because some areas of the world such as Europe and parts of Asia don’t have issues with universal access to water. The website called SDG6data.org is a great display of the progress we have made thus far.

What are the current best methods for water filtration and how do they work?

# data[].attributes.body
Some of the most known methods of water purification are boiling, desalination, distillation, and reverse osmosis. Boiling works exactly like it sounds, and is a method that is used to make water slightly safer to drink. Essentially getting the water as hot as possible while keeping most of it liquid may kill bacteria in the water, however most impurities and chemical pollution will remain in the water. Desalination is the full evaporation and condensation of salt water. Collecting the steam of ocean water does make for safe to drink distilled water, or at least a water with a lower lethal dose than ocean water. Distillation is similar to desalination but it separates water from anything, not salt exclusively. The only downside to these methods that yield 100% pure water is that humans should drink mineral water, not distilled. Mineral water is slightly hypertonic and therefore safe to drink in large amounts, however repeated consumption of hypotonic pure water causes cells to swell, disturbs electrolyte levels and can cause brain damage. Finally, reverse osmosis requires a lab to chemically make water from scratch and is not viable as a solution to quench world thirst.
