1. WATER BASICS
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
