Iron and manganese in water can cause staining of laundry, dishes, and plumbing fixtures, as well as a buildup in pipes that reduces water pressure and quantity. While not hazardous, they become an economic problem when equipment needs replacement. These minerals are more commonly found dissolved in oxygen-poor groundwater and can precipitate out when the water is exposed to air. Bacteria can also cause the iron and manganese to precipitate out faster, concentrating stains. Testing should be done to accurately measure dissolved levels before treatment options are considered.
Quality of water :

Water has its own taste, color, smell and constituents. Not all water can be used for all purposes. Eg. Sea water can not be used by us for drinking. The suitability of water for different purposes is determined by its quality parameters. The Quality of water is equally important than quantity. Even if present in huge amounts, we can not use salt water in many life support activities. Water has its own Physical properties, Chemical composition and Biological Properties. This module highlights the water quality parameters that are essential.
Over the last decade, demand for spring management has increased as traditional spring sources have started drying up or becoming contaminated. In response, communities, NGOs and state agencies began dedicated spring protection programmes. In the Himalayas, the State of Sikkim and organizations such as Central Himalayan Action and Research Group (CHIRAG) and People Science Institute (PSI) started identifying and protecting spring recharge areas around 2007. The difference between these programmes and many other previous efforts is that they went beyond supply-side improvements to focus on the use of hydrogeology to map springsheds for targeted interventions.
The Advanced Centre for Water Resources Development and Management (ACWADAM), a research and capacity-building organization comprised of hydrogeologists and other experts began lending their expertise and building capacity of stakeholders. ACWADAM provides technical support, training and materials in hydrogeology to all network partners as well as others in India and the region. Similar programmes began independently in most of the mountain regions of India. Arghyam, a funding organization that was supporting many of these programmes, noticed that these disparate initiatives shared commonalities despite geographic diversity. They thus organized and funded a meeting of these various organizations in June 2014, and the Springs Initiative was born.
The springs initiative aims to tackle the current water crisis and to ensure safe and sustainable access to water for all, by promoting responsible and appropriate management of aquifers, springsheds, and watersheds and conserving ecosystems in partnership with communities, governments and other stakeholders.
This presentation has been developed as a part of the springs initiative to promote an understanding of springs and their role in mountainous areas.

Water treatment procedure also vary depending upon its use. However, overall picture of water treatment, irrespective of end use shall be considered. An endeavor is made to comprehend the basic chemistry involved in water treatment process. The important stages involved in treatment are as follows: coagulation or flocculation; sedimentation; filtration – slow sand, rapid sand filtration; disinfection – including chlorination and ozonolysis; removal of iron and manganese; softening by lime-soda ash process or deionization method; scale and corrosion control; taste and odor removal; prophylaxiation treatment, i.e., fluoridisation; and specialized treatment for a specific purpose.
Acid rock drainage (ARD) or acid mine drainage refers to the acidic water that is created when sulphide minerals are exposed to air and water and, through a natural chemical reaction, produce sulphuric acid.

https://bit.ly/BabeSideDoll4u Babeside is a company that specializes in creating handcrafted reborn dolls. These dolls are designed to be incredibly lifelike, with realistic skin tones and hair, and they have become increasingly popular among collectors and those who use them for therapeutic purposes. At Babeside, we believe that our reborn dolls can provide comfort and healing to anyone who needs it.
The Healing Power of Babeside's Handcrafted Creations
Our reborn dolls are more than just beautiful pieces of art - they can also help alleviate stress, anxiety, depression, and other mental health conditions. Studies have shown that holding or cuddling a soft object like a stuffed animal or a reborn doll can release oxytocin, which is often referred to as the "love hormone." This hormone helps us feel calm and relaxed, reducing feelings of stress and anxiety.
In addition to their physical benefits, reborn dolls can also offer emotional support. For many people, having something to care for and nurture can bring a sense of purpose and fulfillment. Reborn dolls can also serve as a reminder of happy memories or loved ones who have passed away.
Welcome to the Program Your Destiny course. In this course, we will be learning the technology of personal transformation, neuroassociative conditioning (NAC) as pioneered by Tony Robbins. NAC is used to deprogram negative neuroassociations that are causing approach avoidance and instead reprogram yourself with positive neuroassociations that lead to being approach automatic. In doing so, you change your destiny, moving towards unlocking the hypersocial self within, the true self free from fear and operating from a place of personal power and love.
2. Neither iron nor manganese in water present a health hazard. However, their presence in water may cause taste, staining, and accumulation problems. Because iron and manganese are chemically similar, they cause similar problems. Iron will cause reddish-brown staining of laundry, porcelain, dishes, utensils, and even glassware. Manganese acts in a similar way but causes a brownish-black stain. Soaps and detergents do not remove these stains, and the use of chlorine bleach and alkaline builders (such as sodium carbonate) can actually intensify the stains.
3. Iron and manganese deposits will build up in pipelines, pressure tanks, water heaters, and water softeners. This reduces the available quantity and pressure of the water supply. Iron and manganese accumulations become an economic problem when water supply or softening equipment must be replaced. There are also associated increased energy costs, like pumping water through constricted pipes or heating water with heating rods coated with iron or manganese minerals.
5. Iron and manganese are concentrated in water by contact with rocks and minerals, and occasionally man-made materials like iron and steel pipes. It is usually groundwater supplies that may require treatment for high levels of iron and manganese. Generally speaking, few surface water supplies have high enough levels of either to cause problems. Occasionally discharge of acid industrial wastes or mine drainage may increase iron or manganese to problem levels in surface water.
7. Iron and manganese exist in many different chemical forms. The presence of a given form of iron or manganese in geologic materials or water depends on many different environmental factors. We can often anticipate iron and manganese problems in water by observing a few general principles that affect water chemistry. An important principle to remember about chemical reactions is that, if allowed enough time, they will reach an equilibrium with the surrounding environment. When the conditions of that environment are changed, such as pumping water from an underground aquifer, the chemical equilibrium is upset. This will lead to either solution of certain elements such as iron and manganese or their precipitation.
8. A general rule of thumb is that oxygenated water will have only low levels of iron and manganese. The reason is that both iron and manganese react with oxygen to form compounds that do not stay dissolved in water. Surface water and shallow groundwater (Figure 1) usually have enough dissolved oxygen to maintain iron and manganese in an undissolved state. In surface water, iron and manganese are most likely to be trapped within suspended organic matter particles.
9. Waters that do not have regular contact with the atmosphere tend to be low in oxygen (oxygen poor). Iron and manganese carbonates in an oxygen poor environment are relatively soluble and can cause high levels of dissolved iron and manganese. However, if iron is associated with sulfur as iron sulfide rather than iron carbonate, dissolved iron remains low. Dissolved oxygen generally decreases with depth, so these types of conditions are more likely to occur in deep wells. Sometimes oxygen poor conditions can also occur in relatively shallow wells that have stagnant water with very slow turnover.
10. Iron and manganese problems are most likely to develop in water from wells with high carbonate and low oxygen as shown in the middle well in Figure 1. Problems occur when this type of water is pumped to the surface. The chemical equilibrium is changed upon exposure to the atmosphere. The end result is precipitation of iron and manganese compounds in plumbing, on fixtures, and on clothing, dishes, and utensils.
11. Figure 1. The amount of iron and manganese dissolved in water often follows a trend of low to high back to low again as depth of the well increases.
13. Some types of bacteria derive their energy by reacting with soluble forms of iron and manganese. These organisms are usually found in waters that have high levels of iron and manganese in solution. The reaction changes the iron and manganese from a soluble form into a less soluble form, thus causing precipitation and accumulation of black or reddish brown gelatinous material (slime). Masses of mucous, iron, and/or manganese can clog plumbing and water treatment equipment. They also slough off in globs that become iron or manganese stains on laundry. Bacterial reactions with iron and manganese do not cause any additional precipitation compared to normal exposure to oxygen. However, precipitation caused by bacteria occurs faster and tends to concentrate staining, thus making it more apparent.
15. An additional source for dissolved iron may be the pipelines through which water flows. Water with high salinity or acidity from dissolved carbon dioxide or other acids will be corrosive to metal pipes. In order to establish equilibrium, iron and other metals will be dissolved from the pipelines. If household pipes are being attacked by corrosive water and cause problem levels of metals such as iron, copper, and lead, the water can be treated to reduce corrosivity and level of dissolved metals.
16. Acidity can be reduced by either adding alkaline materials such as sodium carbonate or passing water through filters made of alkaline material. Salinity can be treated by either distillation or reverse osmosis. Because different metals are more or less corrodible, a solution to the problem may be to use a more resistant metal. A Certified Water Specialist should be consulted regarding materials that are best suited to the water conditions.
18. How much iron or manganese in the water is needed to cause these sorts of problems? There is no pat answer to this question, because it varies with each household situation. Standards for iron and manganese are based on levels that cause taste and staining problems and are set under EPA Secondary Drinking Water Standards. For most individuals 0.3 parts per million (ppm) of iron and 0.05 ppm of manganese is objectionable. Usually iron and manganese do not exceed 10 ppm and 2 ppm, respectively, in natural waters. Iron and manganese are found at higher concentrations; however, that condition is rare.
20. The need to test for iron and manganese in water is not as critical as it is for other types of contaminants that can cause health problems. Iron and manganese are not a problem in household water until they become detectable by the senses. Consequently, elaborate laboratory analyses are not required to determine if iron or manganese are a problem. Laboratory analyses for iron and manganese are needed to quantify the problem.
21. Exposure of the sample to air will cause precipitation of iron and manganese. To get an estimate of the amount of iron and manganese originally dissolved in the well water, precipitation must be prevented or the precipitated material must be redissolved. Before sampling for iron and manganese, a Certified Water Specialist should be consulted. They will recommend a sampling procedure that will provide an accurate estimate of dissolved iron and manganese in the source water.
