Question

what are Canal colonies ​

Answer 1

Explanation:

Bacteriological water analysis is a method of analysing water to estimate the numbers of bacteria present and, if needed, to find out what sort of bacteria they are. It represents one aspect of water quality. It is a microbiological analytical procedure which uses samples of water and from these samples determines the concentration of bacteria. It is then possible to draw inferences about the suitability of the water for use from these concentrations. This process is used, for example, to routinely confirm that water is safe for human consumption or that bathing and recreational waters are safe to use.

The interpretation and the action trigger levels for different waters vary depending on the use made of the water. Whilst very stringent levels apply to drinking water, more relaxed levels apply to marine bathing waters, where much lower volumes of water are expected to be ingested by users.

Answer 2

Explanation :

built a network of irrigation canals to transform semi-desert wastes into fertile agricultural lands that could grow wheat and cotton for export.

The Canal Colonies, as the areas irrigated by the new canals were called, were settled by peasants from other parts of Punjab.
