Local Stream Contamination

Local Stream Contamination

• The quality of ones water is important.
• Airports say it is their primary concern.
• Deicing chemicals are used on aircrafts, then
  runoff into nearby streams causing contamination.
• They contaminate both ground and surface water.

Deicing Chemical

• These chemicals are biodegradable and threatening
  to aquatic life. It breaks down in water and
  consumes oxygen.
• Deicers work to break up snow or ice so that it
  can be removed more easily. The chemicals work by
  dissolving slowly on contact, while some
  chemicals help to melt the ice or snow.
• Chemical deicers typically are various chloride
  salts calcium, magnesium, potassium, or sodium.
  These five chemicals and combinations of them
  account for essentially all roadway deicers, with
  CaCl2 being the most effective and most popular.

• Cumulative exposures to deicing fluids and their
  chemical components present a major concern to
  human health, animal welfare, and the
  environment.
• These chemicals if used should be contained and
  kept in a contained area away from streams and
  runoffs.
• The lethal dose in adults is 1.4 ml or 3.3 fl. No
  studies have been done on its effects on humans.
  However, each winter large amounts of fish and
  wildlife are poisoned to death by aircraft
  deicing chemicals.

• The sweet taste of the deicers fools animals of
  its toxicity , and occasionally it has led to the
  death of animals that have licked up deicers that
  has leaked onto the ground.
• When ingested, it depresses the central nervous
  system and can be fatal to humans even in small
  quantities.
• The aquatic life in the streams is effected along
  with the animals which drink from the streams.
• As this chemical runs into local areas and sinks
  into the ground these chemicals work their way
  into the near by wells and water holds.

7

• Lawsuits across the nation have been made to stop
  the runoff of deicers from airports.
• Airports have standards they are supposed to
  follow and must have a agreement in order to let
  chemicals run off into streams.
• But, who is to stop them and who is to know of
  the runoff into nearby streams. No one if one
  complains or becomes ill or dies.

8

• I feel deicers should be contained better then
  they say they are being contained.
• The water we drink and live around in
  contaminated by the chemicals of the airport.
• I am against the deicing method of aircrafts and
  if something must be used it should be a non
  toxic chemical or controlled better.
