Drinking
Water Problems Chemical
contaminants and other impurities may be harmful to your health.
The
most important water in your home is the water that you drink and
cook with. Having the highest quality drinking water will insure
that aesthetic concerns (taste and odor), and health concerns (making
sure that the water is free from harmful contaminants) are avoided.
Reverse
Osmosis water filtration treats two major drinking water problems:
Reduces
contaminents that are harmful to your health
Improves
the taste and smell of your drinking water.
REDUCES
CONTAMINENTS
CYSTS
A Cyst is a closed pocket or pouch of tissue; a cyst can be filled
with air, fluid, pus, or other material. Common water-borne microbiological
cysts are Cryptosporidium or Giardia cysts.
CRYPTOSPORIDIUM
Cryptosporidium is a parasite that enters lakes and rivers through
sewage and animal waste. It causes cryptosporidiosis, a mild
gastrointestinal disease. However, the disease can be severe
or fatal for people with severely weakened immune systems.
GIARDIA
Giardia lamblia is a parasite that enters lakes and rivers through
sewage and animal waste. It causes gastrointestinal illness (e.g.
diarrhea, vomiting, cramps). Giardia outbreaks can occur in communities
where water supplies become contaminated with raw sewage. It can
be contracted by drinking water from lakes or streams where water-dwelling
animals such as beavers and muskrats, or where domestic animals
such as sheep, have caused contamination.
SODIUM
Need
TOTAL
DISOLVED SOLIDS (TDS)
Dissolved solids (atoms) are extremely small, usually less than
8 ten thousandths of one micron in size. Some dissolved solids
(e.g. hardness minerals, alkalinity, sulfate, etc.) are harmless
but may cause objectionable taste and scale problems. Others,
such as lead, nitrate, sodium, fluoride, arsenic, mercury, etc.,
can be harmful. The amount of these contaminants allowed in drinking
water is limited by government standards. Total Dissolved Solids
(TDS) refers to the overall amount of all dissolved solids found
in any one tap water sample.
CHROMIUM
VI
Chromium is ubiquitous in the environment, occurring naturally
in the air, water, rocks and soil. It is used in stainless steel,
electroplating of chrome, dyes, leather tanning and wood preservatives.
It occurs in several forms, depending on pH, the most common being
chromium VI. Natural sources of water contain very low concentrations
of chromium. It is a micronutrient. High doses of chromium VI
have been associated with birth defects and cancer. Plants and
animals do not bioaccumulate chromium; therefore, the potential
impact of high chromium levels in the environment is acute toxicity
to plants and animals. In animals and humans this toxicity may
be expressed as skin lesions or rashes and kidney and liver damage
IMPROVES
TASTE AND ODOR
CHLORINE
TASTE AND ODOR
Chlorine is a disinfectant that many water suppliers add to drinking
water to kill germs such as giardia and e coli. Especially after
heavy rainstorms, your water system may add more chlorine to guarantee
that these germs are killed. Chlorine can contribute some adverse
effects, such as bad taste and odor. Some people who use drinking
water containing chlorine well in excess of EPA's standard could
experience irritating effects to their eyes and nose or stomach
discomfort.
HYDROGEN
SULFIDE TASTE AND ODOR
Hydrogen Sulfide is a form of sulfur commonly found in drinking
water. It is a common nuisance contaminants that does not usually
pose a health risk at the concentrations found in domestic water
supplies. Hydrogen sulfide gas produces an offensive "rotten
egg" or "sulfur water" odor and taste in the water.
In some cases, the odor may be noticeable only when the water
is initially turned on or when hot water is run. Heat forces the
gas into the air which may cause the odor to be especially offensive
in a shower. The offensive odor of hydrogen sulfide gas generally
makes testing unnecessary. Most people recognize the "rotten
egg" or "sulfur" odor and proceed to correct the
problem. Hydrogen sulfide is one of a few water contaminants that
can be detected at low concentrations by the human senses. A nuisance
associated with hydrogen sulfide includes its corrosiveness to
metals such as iron, steel, copper and brass. It can tarnish silverware
and discolor copper and brass utensils. Hydrogen sulfide also
can cause yellow or black stains on kitchen and bathroom fixtures.
Coffee, tea and other beverages made with water containing hydrogen
sulfide may be discolored and the appearance and taste of cooked
foods can be affected
Sediment
And Rust
Sediments include dirt, rust, and particles of plant or animal
matter that are suspended in water.
Sediments
are the largest water-borne impurity, although most are too small
to be seen. Colloidal sediments can be 1/100 of a micron while
large particles can be 200 microns or more in size. Sediment problems
include cloudy, unappealing water and clogging of water passages
in appliances.
