| Q:
Why is tap water cloudy?
A: A major source of turbidity or cloudy water is
sediment that finds its way into the water system.
This is noticeable during periods of heavy, sustained
rainfall when the forces of erosion are at a maximum
in the watersheds. Also if water is very soft corrosion
occurs within the water distribution system. Corrosion
products (such as rust) can also discolor the water.
There are a number of conditions which can result
in local turbidity upset including construction or
pipes being changed, high flows due to a fire or a
flusher truck filling, or high flows due to hot weather.
In general, anything that may change the flow of water
and cause it to sweep particles into the water current
may result in cloudy/colored water. Unless there is
a general problem with cloudy water, flush the tap
to clear up the problem. If this does not work, contact
your municipality to flush the main(s) feeding the
residence in question.
Q:
I don't like the taste/smell/appearance of my tap
water. What's wrong with it?
A: Even when water meets EPA's standards, you may
still object to its taste, smell, or appearance. EPA
sets secondary standards based on these aesthetic
characteristics (not health effects) which water systems
and states can choose to adopt. Common complaints
about water aesthetics include temporary cloudiness
(typically caused by air bubbles) or chlorine taste
(which can be improved by letting the water stand
exposed to the air).
Q:
Why does my water taste and smell like chlorine?
A: All public drinking water supplies are required
federal and state "Safe Drinking Water Regulations"
to disinfect drinking water for health and safety
reasons. Chlorine is a common disinfectant. For this
reason some drinking water supplies my have a slight
chlorine taste and odor present. Most over the counter
filters should help to eliminate the smell and taste
of the chlorine. Occasionally, (most commonly during
the late summer/early fall or during the winter when
the lakes are covered with ice) low levels of ammonia
arising from natural processes can be found in the
water. The ammonia combines with chlorine to produce
chloramines which have a very chlorinous taste and
odor. This is not harmful but can be very displeasing.
The problem dissipates once sustained rainfall or
spring snow-melt occurs which results in a good exchange
of water through the lake. Recently concerns regarding
the presence of chlorinated compounds in drinking
water have become an issue.
Q:
Why does my drinking water taste or smell "funny"?
Will this smelly water make me sick?
A: The four most common reasons for bad tasting water
or smelling water are;
a).
A noticeable taste can come from the chlorine that
is added to the water to kill germs. Heavily chlorinated
water may contain "reaction products." These
products cause no taste and odor and are limited by
the US Environmental Protection Agency's rules.
b).
A rotten-egg odor in some groundwater is caused by
a non-toxic (in small amounts), smelly chemical- hydrogen
sulfide - dissolved in the water.
c).
As some algae, bacteria, and tiny fungi grow in surface
water sources, they give off nontoxic, smelly chemicals
that can cause unpleasant tastes in drinking water.
Different algae cause different tastes and odors -
grassy, swampy, and pigpen, as examples - and the
little fungi can cause an earthy-musty taste.
d).
Metallic tastes can come from copper that has dissolved
from copper pipe and from iron from rusting on iron
pipes. Copper can cause short-term health problems
like diarrhea and cramping. Iron has no effect on
health.
