Metal contaminants in our drinking water

It is a known fact that metals naturally occur on any natural freshwater source. Our bodies through ages of adaptation had evolved to naturally render them harmless and some are even considered as micronutrients in small amounts like copper.

The body could absorb about 1,000 ug(micrograms) of copper a day. However any amount beyond that may cause vomiting, diarrhea, stomach aches, and nausea. Unless contamination is caused by pollution, any naturally occurring amounts of copper on our water source is acceptable.

Certain heavy metals like Mercury are considered toxic even at small amounts. Health effects are usually related to brain damage resulting to memory loss and hallucinations. It could also result to other diseases like, Acrodynia (pink disease), Hunter-Russell syndrome, and Minamata disease. Mercury contamination of natural water sources in central California caused by abandoned mercury mines has affected at least 100,000 residents. These abandoned mercury mines had been closed for more than two decades now. Only recently that studies have confirmed the higher body levels of mercury on local Indians who rely on natural water sources.

Like mercury, lead also damages the nervous system. Earliest evidence of lead artifacts date back 6400 B.C. Lead has a long list of industrial use, notably for car batteries and semiconductor applications. Its wide use makes it a potential pollutant once these items are discarded improperly. Water pollution through solid and industrial wastes is the main cause of lead contamination. Indications of lead poisoning may vary but has been observed to be related to stunted growth, learning disabilities, and anti-social behaviors of children. In general, lead poisoning effects tend to be long term and irreversible.

Another notorious metalloid found in drinking water is the arsenic. First studied in 1250 by Albertus Magnus, it is widely used for wood treatment due to its toxicity to wood insects. Its poisonous reputation had made it a favorite tool for murder mystery tales. Throughout history, a lot of famous victims including Napoleon himself allegedly died of arsenic poisoning. Although naturally occurring on 200 types of mineral species, most groundwater contaminations are caused by mining, smelting of non-ferrous metals and burning of fossil fuels. When ingested through drinking water and depending on the dosage, symptoms may vary from skin disease, hearing loss, diabetes and cancer.

These are just some of the metals that are naturally present on ground water. As long as the acceptable levels are achieved, none of the harmful symptoms would occur. Protecting our drinking water at home should be a primary objective for all.

Reverse Osmosis For Your Home is Expensive

Reverse Osmosis systems are known to be used best for desalinating water. It is a trusted process employed by a lot of industries to treat their cooling systems. Since the advent of home based filters, the reverse osmosis system had also been used to filter water even for our drinking consumption.

The process of reverse osmosis is pretty simple. A semi permeable membrane acts as a filter to choose only what type of substance it would let pass through and water is constantly forced through it by pumps. Bacteria and other contaminants are left out and only clean water is allowed to pass. Anything the semi permeable membrane would reject would be discarded as waste water.

Osmosis was likened to it as reversed because in natural osmosis the less salty water separated by a semi permeable membrane is pushed by the osmotic pressure to go to the saltier water to attempt to even out their concentrations.

This osmotic force is duplicated by pumps and instead of less concentration to more concentration; the reverse osmosis does it the other way. The more concentrated water is assumed to be the untreated or contaminated water and pushed to the semi permeable membrane to become less concentrated or free of impurities.

The process of reverse osmosis is efficient and effective if the natural way of the process is duplicated to perfection.

This is where the problem arises. All the process involved with reverse osmosis including the electric pumps and constant flowing untreated water requires power and resources. The artificial semi permeable membrane needs to be replaced on regular basis. The filtering capability is only as good as how the semi permeable membrane was made for. In many cases, reverse osmosis would even block out healthy minerals needed by our bodies.

Reverse osmosis also wastes water. On the average, only about 15%-25% of the processed water could be consumed. The remaining are discarded as waste water.

Your house pipelines could also be compromised. Since reverse osmosis produces acidic water and acid eats up metal, it may aid in pipeline corrosion.

After considering the inefficiency in operating power, the water wastage, the expensive maintenance, tasteless water stripped of all minerals, and the disintegration of your house pipeline structure, one should have careful consideration before using reverse osmosis as a house filter.
