Answer:
Sewage may be enter entering the water.
Explanation:
- People and warm-blooded animals' intestines contain the harmless E. coli bacteria. But some strains can make you sick. In most cases, the presence of E. coli in a sample of drinking water denotes recent faecal contamination.
- It is necessary to offer potable, pure, healthy, and wholesome drinking water. Water that is safe to drink may contain some contaminants. Salts like magnesium, calcium, carbonates, bicarbonates, and other minerals can be found in small amounts in it. Purity and safety levels are relative and up for debate.
- Water that can be provided to a user and is suitable for drinking, food preparation, personal hygiene, and washing is known as safe drinking (potable) water. The required standards for water quality (chemical, biological, and physical) must be met.
