What may be in your water

Clean water is essential to good health

Water makes up between 55% and 60% of our body. As a result the quality and amount of water we drink is critical to our individual long term health

Water from the tap

The central water suppliers do their best to make safe the water that is delivered to your home. They are, however, processing millions of litres per day and delivering this water through miles of pipes of various ages The following is a brief description of each of these contaminants and their possible effects. Click on the headings to go to a description of each contaminant:

1. Rust and other particles: Found in water from old pipes

2. Chlorine: Gas used to kill bacteria and viruses and causes sensitivity in people who drink it.

3. Plastics

4. Coliform Bacteria: These include E-coli and salmonella resulting from water contaminated by human and animal waste.

5. Giardia: a parasitefound in the intestines of humans and animals.

6. Cryptosporidium: contamination from faecal material.

7.Oestrogen, Synthetic Oestrogen and other organics: contamination frompesticides, herbicides and the residue from the birth control pill.

8. Lead and Mercury: heavy metals that leach form old lead pipes and metals that are found in ground water

9. Iodine: from ground water

10.Fluorine and Fluoride: fluoride that is either naturally in your water or synthetic fluoride that is added to reduce tooth decay

Quality standards of our water filter products: our filtration products are independently tested

1. Rust and other particles

The source of rust particles in water is usually old iron pipework which is common where mains supplies date back many years. Our filters have an absolute filtration rating of 99.99% of microns 0.9 or larger.

2. Chlorine

Chlorine is, by itself, a yellow-green poisonous gas. It is an inorganic element that cannot exist by itself in nature but needs to bond to another element. The most common element being sodium, hence, sodium-chloride, or salt. Chlorine has a corrosive effect on organic matter. Many scientific studies report that chlorinated water can destroy polyunsaturated fatty acids and vitamin E. It can also destroy intestinal flora in the gut that help digestion of food and protect the body from harmful pathogens. It is not uncommon for chronic skin conditions to clear up or greatly improve by removing it. These skin conditions include acne, psoriasis, seborrhea and eczema. In the chlorination process, chlorine combines with natural organic matter such as decaying vegetation to form trihalomethanes (THM’s) and haloforms. These are known cancer causing substances. Chlorine is removed by the activated carbon in either the whole house systems or the drinking water units.

3. Plastics in your water

Scientists conducted a study of tap water which was reported by The Guardian in 2017.  This highlighted the fact that billions of people worldwide are drinking water contaminated by plastic particles.  Overall 83% of the samples were contaminated with plastic fibres.  If we drill down further, the US had the highest contamination rate with 94% of the samples containing plastic fibres. The UK, Germany and France had the lowest; however this was still 72% of samples which is not insignificant. Fibres are shed via the everyday wear and tear of clothes and carpets and the common use of tumble driers, venting out into the open air may add to the concentration of fibres in the atmosphere.  

The WHO have announced a health review into the potential risks of plastic in drinking water after a controversial new study of popular bottled water brands revealed that more than 90% contained tiny pieces of plastic.  The most common type of plastic fragment found was polypropylene, which is the same type of plastic used to make bottle caps.  There are a range of aspects to consider including how this is happening, measures that need be introduced going forward and the overall impact on health. It has been suggested that plastic microfibres are easily airborne and could be present both within and outside the factories, circulating via fans and on clothing.  

4. Coliform Bacteria

Coliform bacteria include E-coli, Salmonella, Legionella, Cholera, and Salmonella Typhi (typhoid). They live in soil or vegetation and in the gastrointestinal tract of animals. The majority of coliform bacteria are harmless but if E-coli is found it is likely that the water supply has been contaminated. Contamination sources include human or animal waste. If pipes become contaminated or are not adequately chlorinated there is a chance that coliform bacteria may be present. Because of their size bacteria are removed by the ceramic outer shell of the UltraCarb and Super Stericile filters used in our drinking water systems. 

5. Giardia Lamblia

Giardia are flagellated protozoa that are parasitic in the intestines of humans and animals. Giardia infections can occur through the ingestion of dormant microbial cysts in contaminated water, food or fecal-oral route. Once the cyst enters the stomach, the organism is released into the gastrointestinal tract. Here it will adhere to the intestinal wall. Giardia causes a disease called giardiasis. Symptoms include diarrhoea, abdominal cramps, nausea, weight loss and general gastrointestinal distress. Giardia Lambia are removed by the ceramic outer shell of the UltraCarb and Super Stericile filters used in our drinking water systems. 

6. Cryptosporidium

Cryptosporidium is spread by transmission of oocysts via drinking water which has been contaminated. This contamination comes from faecal material. Once inside its host, the oocyst breaks into four moveable spores that attach to the walls of the gastrointestinal tract. They eventually form oocysts again that can be excreted. Symptoms include diarrhoea, headache, abdominal cramps, nausea, vomiting and a low fever. For people with a compromised immune system cryptosporidiosis may become life threatening. Individuals such as infants, the elderly or those with AIDS are particularly at risk. Water treatment processes that utilise coagulation, sedimentation, filtration and chlorination may remove it. However due to its resistance to chlorination and its small size, these centralised treatments may not work.  Cryptosporidium are removed by the ceramic outer shell of the UltraCarb and Super Stericile filters used in our drinking water systems. 

7. Oestrogen, Synthetic Oestrogen and other organics

There is increasing concern over the effects of oestrogen and synthetic oestrogen residues in the water supply. The activated carbon in our filters is known to remove both oestrogen and synthetic oestrogen. Because quantitative tests have not been carried out, we cannot state how much of these chemicals will be removed. The only way to remove 100% is either distillation or reverse osmosis.

8. Lead and mercury

Lead can cause physical and mental issues. These include behavioral problems and learning difficulties, high blood pressure, strokes and heart disease. It can also lower sperm count. The lead removal of the Ultracarb filter candle is 98.3%. Heavy metal filters for the Gravity Water Filter will also remove other heavy metals. These include aluminium, copper, cadmium and mercury.

9. Iodine

Iodine plays an important role in the production of thyroid hormones. The human body usually contains about 10-15 mg of this substance. The larger part can be found in the thyroid gland. The recommended daily intake for iodine is between 150 and 200 μg. Generally this dose is achieved by eating kitchen salt, to which iodine is added.

Worldwide iodine uptake differs greatly between different peoples. People that eat large amounts of fish take up higher amounts of iodine. Iodine may also negatively influence the thyroid gland. This is usually associated with hyperactivity. After long term exposure sensitive people may develop symptoms such as itching, bronchitis, sleeping disorders and rashes. Skin contact with concentrated iodine may lead to pigmentation. Iodine fumes cause eye and lung irritation.

Iodine is removed from water by means of activated carbon.

10. Fluorine and Fluoride

Fluorine has a high electron affinity and actively forms stable compounds called fluorides. These have strong oxidizing properties. Fluoride occurs naturally in some waters, but is frequently added to municipal water supplies. This is due to a widely held belief that it prevents dental decay.

Fluoride is more difficult to remove than most water contaminants. For practical purposes, there are three choices for removing fluoride from drinking water. These are distillationreverse osmosis, and filtration. Filtration occurs through a special fluoride/arsenic reduction medium called activated alumina.

Each system is effective at removing fluoride. Reverse Osmosis (RO) systems have a high cost in waste water that is used in the filtration process. Distillers use electricity to boil the water so have a high energy cost. Activated alumina filters have the lowest cost since the fluoride is removed by a chemical process.

Steam distillers remove a high percentage of fluoride. Any good reverse osmosis unit will provide fluoride reduction of 95% or better. Activated alumina, called AAL, removes fluoride well, but requires a relatively large bed and slow flow rates. As it requires such slow flow rates, AAL is not practical for whole house filtration.
