Water Facts
  • Water is called a UNIVERSAL SOLVENT because it dissolves part or whole of almost anything it comes in contact with
  • Even metals, rocks & gases
  • Water does not exist as “PURE WATER” naturally.
  • It always carries some dissolved substances with it, even if in extremely small quantity
  • Things we don’t want to be present in water are called CONTAMINANTS
  • What we call as a contaminant depends on how we are using the water

Types of Contaminants

  • Suspended
    • Dirt rust, sand etc.
  • Dissolved
    • Aesthetic – Smell, taste, odour, colour etc.
    • Health -Pesticides, heavy metals
  • Microbiological
    • Bacteria, viruses, cysts

The Water Cycle – Ground Water

  • Below the earth’s surface lie minerals such as iron, limestone, manganese, etc
  • When rainwater falls, it picks up carbon dioxide in the atmosphere forming CARBONIC ACID.
  • When rainwater seeps into the earth, the carbonic acid helps dissolve minerals that are present below the surface.
  • That’s why water from deep wells is generally high in dissolved impurities
  • Water that directly falls in lakes, rivers etc does not dissolve minerals. So lakes & rivers generally have low mineral content
  • Water from “run off” picks up sand, mud, silt dirt etc before flowing to lakes, ponds rivers etc.

Where do we get our water from at home

  • Municipally treated (if you get a water bill)
    • Treated at a central treatment facility
    • Pumped through pipes into homes
    • Homes on MT water will have a water meter
  • Well or lake
    • Private drilled or dug wells, cistern, lake etc.
    • Pumped into the home by a private pump
