Acidity (pH Balance)
Source: Chemistry.about.comAlthough the pH of pure water is 7, drinking water and natural water exhibits a pH range because it contains dissolved minerals and gases. Surface waters typically range from pH 6.5 to 8.5 while groundwater ranges from pH 6 to 8.5. Water with a pH less than 6.5 is considered acidic. This water typically is corrosive and soft. It may contain metal ions, such as copper, iron, lead, manganese and zinc. The metal ions may be toxic, may produce a metallic taste, and can stain fixtures and fabrics. The low pH can damage metal pipes and fixtures.
Water with a pH higher than 8.5 is considered basic or alkaline. This water often is hard water, containing ions that can form scale deposits in pipes and contribute an alkali taste.

NSF/ANSI Standard 53: Drinking Water Treatment Units – Health Effects
Overview: Standard 53 addresses point-of-use (POU) and point-of-entry (POE) systems designed to reduce specific health-related contaminants, such as Cryptosporidium, Giardia, lead, volatile organic chemicals (VOCs), MTBE (methyl tertiary-butyl ether), that may be present in public or private drinking water.
NSF/ANSI Standard 58: Reverse Osmosis Drinking Water Treatment Systems
Overview: This standard was developed for point-of-use (POU) reverse osmosis (RO) treatment systems. These systems typically consist of a pre-filter, RO membrane, and post-filter. Standard 58 includes contaminant reduction claims commonly treated using RO, including fluoride, hexavalent and trivalent chromium, total dissolved solids, nitrates, etc. that may be present in public or private drinking water.
NSF/ANSI Standard 62: Drinking Water Distillation Systems
Overview: Standard 62 covers distillation systems designed to reduce specific contaminants, including total arsenic, chromium, mercury, nitrate/nitrite, and microorganisms from public and private water supplies.

Water suppliers use disinfectants, like chlorine, to destroy pathogens (disease-causing organisms) from drinking water. However some pathogens are highly resistant to standard disinfection methods (such as Cryptosporidium).
Filtration has a high effectiveness in removing Cryptosporidium when using an absolute less than or equal to 1 micron filter (NSF Standard 53 or 58 rated “cyst reduction / removal” filter).

Reverse Osmosis is the best way to remove fluoride from drinking water. Thin Film Composite Reverse Osmosis Membranes remove between 85-92% of Fluoride.
Aries Filter Works Fluoride reduction cartridges contain Resintech SIR-900, in which fluoride is removed by a chemical reaction with the media. The process is flow and pH sensitive. The best results are obtained when the flow is limited to about l GPM/cu.ft. and the pH is held at 5.5. Higher flows and higher or lower pH causes a significant loss of capacity. The best capacity obtainable is approximately 0.2 lbs. per cu.ft. Leakage of fluoride is generally less than 0.1 mg./L to breakthrough.

Iron poses no health hazards but can but can cause water to have an unaesthetic, reddish brown color and can cause staining. Well water systems using Filox and Polyphosphate cartridges can remove excess amounts of iron from water. Water softener systems can reduce iron (excluding dissolved organic-iron compounds) to low levels by ion exchange. Aries Filter Works also has cartridges specifically for the removal of heavy metals and also cartrides containing KDF85, which is used for the reomval of iron and sulfur from water.

Lead has been mined and used by humans for thousands of years and was only recently discovered in the last few decades. Lead can accumulate in the body’s soft tissue and bones and cause poisoning, disrupt body processes, and is toxic to many internal organs. Symptoms of lead poisoning are irritability, confusion, headaches, abdominal pain and comas, seizures & even death in extreme cases.
“ There is no known safe level of exposure to lead.”
Infants and small children are at greater risk due to being constantly developing and higher absorption from a smaller body mass. Lead is particularly damaging to the nervous system, which can cause learning and behavior disorders. Pregnant mothers with high blood lead content may cause poisoning in infants, and are more likely to have a low birth weight or premature birth.

Boiling your water will not remove mercury from it. Most systems with thin film composite membranes or filters containing KDF media will reduce mercury levels in drinking water, like reverse osmosis, under sink, and most Everpure systems. There is also specialty cartridges and filters made to complete remove mercury from drinking water, the types we carry are listed below.

Sediment is the most common problem in water filtration, so almost all of the water filtration systems we offer has a filter or stage to deal with it. Sediment cartridges come in several types (pleated, melt blown, string wound and high temperature) and, like their name suggests, remove sediment from water.

The Hydrologic Cycle (also called the Water Cycle) is the continuous movement of water in the air, on the surface of and below the Earth.
This cycle is the exchange of energy which influences climate. When water condenses, it releases energy and warms the environment.
90% of the garbage floating in the Earth’s oceans is plastic and less than 5% of all plastic is recycled.
The patch mostly consists of pelagic plastics, formed from plastic bags, plastic water bottles, bottle caps and styrofoam.
Hydraulic fracturing (sometimes referred to as fracking or hydrofracking) is a relatively new form of natural gas extraction.
The fluids used in the fracking process flow back to the surface, often entering the water table or polluting the drilling area, and sometimes improper disposal of waste water from the wells.
As our technology advances, so do new forms of pollution and contaminants that effect our environment and our health.

Chlorine has long been recognized as an oxidative agent, meaning that it not only kills the germs in the water supply; it will damage any living tissue with which it comes in contact. And your skin, like the rest of your organs, is living tissue. But that’s not the only problem.
Since the discovery of its health benefits in the mid-1940’s, fluoride is often added to the public water supplies of industrialized countries in order to reduce the populations tooth decay, which is especially effective in low income communities, where good dental hygiene may be too costly.
Chromium-6 was found in the drinking water supply of the southern California town of Hinkley and brought to national attention by Erin Brockovich.
The EPA is reviewing effects of Chromium-6 after a recent report brought to light dangerous levels in a number of major US cities.
Giardia is a flagellated protozoan parasite that colonizes and reproduces in the small intestines of humans and other animals, which can cause giardiasis.
Symptoms of Giardiasis usually show after 3 to 4 days, and include gastrointestinal and constitutional problems.
Cryptosporidiosis is a disease caused by the parasite Cryptosporidium parvum.
Since a outbreak in 1993 in Wisconson, new attention has been focused on determining and reducing the risk for Cryptosporidiosis from community and municipal water supplies.
