| How Complicated is Water?
Surprisingly the water we drink from our taps may not
be good enough for our pools. Tap water can have high
or low pH levels. It can have too much or too little
calcium and carbonates. It can have high levels of iron
and other minerals that can cause stains, scale, and
corrosion. Improper levels of pH, minerals and organic
matter can and often will prevent pool chemicals from
doing their work in the water.
The suitability of water for swimming pool use depends
on its quality. Water quality is determined by the amounts
and kinds of suspended and dissolved substances; the
degree of acidity or alkalinity; temperature; color
and transparency; taste and smell; and the presence
of undesirable microorganisms.
All natural waters contain dissolved inorganic and
organic substances. The total dissolved-solids burden
of pool water may be as high as 2000 parts per million
(ppm), the majority of dissolved solids are calcium,
magnesium, sodium, potassium, sulfate, chloride, carbonate,
bicarbonate, and silica.
Many pollutants may also be found in solution. These
may be excessive amounts of substances normally present,
such as nitrates, phosphates, and certain metals, or
they may be materials not naturally found, such as pesticides,
poisons and agricultural remedies.
There are also oils from suntan lotions, humans, leaves
and car exhaust fumes.
Suspended sediment is an important constituent of
water quality, because it affects light penetration,
and makes water undesirable for swimming. Sediment is
also linked to other water-quality factors because pesticides,
phosphates, and bacteria may be attached to sediment
particles. Fecal-coliform bacteria in water are an important
index of bacteria.
Water temperature is important because it influences
the metabolic rate of aquatic organisms and the rates
of chemical reactions.
