Tap water
* All tap water contains chlorine and possibly even chloramine.

  - low conductivity
  - salt
  - is safe for healthy adults and children
  - provides aquatic habitats
* Most tap water uses for irrigation
  - nasal irrigation
  - waters contain heavy minerals and chemical purifiers, with a pH in the alkaline range
* Some tap water contains chemicals
  - concentration
  - lead, cadmium, and arsenic at levels that are of public health concern
  - has minerals
* can add unwanted mineral deposits

  - chemicals that affect the taste of the tea
* contains chlorine which can damage the bio filter
  - is used to kill bacteria and it is soluble in water
  - chlorine, fluoride and other potentially allergenic chemicals
  - less oxygen than rain water and probably contains chlorine
* contains many chemicals
  - impurities such as iron, sulphur, phosphorus, even chlorine
  - soluble chlorine which is constantly escaping as chlorine gas
  - too many minerals for the ferret to handle, which can cause health problems
  - trace amounts of chemicals such as radon and chlorine
* good conductor of electricity.
  - chlorine that kills bacteria, good or bad
  - far too many contaminants to be used in laboratories or for scientific purposes
  - minerals and ions in it as well as bacteria
  - thousands of particles in it
  - very little oxygen in it
* is O-K to use but it causes salts to accumulate in the soil
  - acceptable for watering most plants
  - almost always safe to drink
* is considered safe in Nairobi and Mombasa
  - Nevada and throughout the United States
  - Oregon and throughout the United States
  - desalinated
  - drinkable everywhere
  - filled with all sorts of materials which are toxic to humans and to aquarium fish
* is filtered by activated charcoal
  - to remove chlorine and other substances that are harmful to aquatic organisms
  - fluoridated to help prevent tooth decay
* is from desalination plants and is safe to drink
  - rainwater caught on the roof
  - generally a very good conductor because it has plenty of ions
* is generally safe to drink although some take the precaution of boiling it
* is potable, and dairy products pure
  - except for occasional winter floods
  - purified and has a very low bacterial count
  - recommended for babies because it contains fluoride which bottled water lacks
* is safe for drinking
  - to drink although it can often be salty in taste
* is safe to drink in all cities and resorts
  - any Australian cities or towns
  - nationwide
  - theoretically safe to drink in all places
  - treated to kill bacteria, and fluoridated, which is important for teeth
  - un-safe to drink
  - unsafe for drinking
  - used only for doing dishes
  - usually brown and contains sediment
* presents a variety of inorganic minerals which our body has difficulty absorbing.
* runs only one or two days a month, and it is often filthy when it comes.
* smaller source of radon in air.

Tidal water
* Most tidal water provides habitats.
* Some tidal water contains very little salt
  - passes through holes
* are also abundant in smelt and mackerel.
* floods the land surface less often than daily.
* makes swimming in the warmest cove.

Tropical water
* Most tropical water has concentration.
* acts as a cyan filter and quickly removes color from a scene, beginning with red.
