Information
Tests Performed
pH -
Determined on a
scale of 0 to 14 with 7 being neutral, measures acidity. The pH of water is
affected by its age and contaminant chemicals. Acidic waters, those with a low
pH, are especially dangerous as they magnify the toxicity of certain chemicals
and metals and slowly dissolve copper pipes.
Hard Water-
Hardness keeps soap from lathering, working, and rinsing off
as it should, often leaving an invisible film. On skin, this blocks pores,
attracts and holds dirt and bacteria, and causes chapping, itching, and
dryness. Washed clothing is not as soft and clean as it should be. With
softened water, the time required for housecleaning is cut from 4 hours to
less than 2 1/2 hours and appliances consume up to 22% less energy. Hard water
clogs pipes and plumbing fixtures, leaves spots on glasses and dishware, and
discolors water and makes it taste bad. In the U.S., about 85% of the
population has hard water, resulting in numerous expenses in hot-water bills
and appliance replacements.
Copper-
Copper
concentrations in drinking water are usually extremely low and, of
consequence, not considered an immediate health hazard. However,
concentrations exceeding 1 mg/L cause bitter-tasting water. Larger doses
result in vomiting and may lead to liver damage. When coupled with low pH
levels, high levels of copper can be strong indicators of deteriorating copper
pipes, resulting in costly repairs.
Chlorine-
Chlorine is an
excellent disinfectant. In areas of the world where chlorine is not added to
drinking water, thousands die daily of waterborne diseases from typhoid to
cholera. However, chlorine gas even at low concentrations can kill or pose
long-term health threats. A recommended less than 0.5 mg/L of chlorine is
needed to kill bacteria without causing water to smell or taste unpleasant.
COD-
Chemical Oxygen Demand
(COD) is an indicator for the amount of chemicals or bacteria in water. Ground
water contamination or bacterial growth is a common problem in houses supplied
with well water. The organism responsible for Legionnaire's Disease thrives in
hot water heaters below 103°F.
Lead (Future Test)
-
Lead is toxic by
ingestion and inhalation. When ingested lead enters the blood stream, it is
stored in the body and extended exposure may lead to irreversible damage to
the nervous, reproductive, and blood forming systems. This may cause learning
disabilities, delinquent behavior, hyperactivity, kidney and heart disease,
and brain damage.
