Answer

To solve the question regarding the high amount of E. coli in water, we can follow these steps:

### Step 1: Understand what E. coli is
E. coli, or Escherichia coli, is a type of bacteria that is commonly found in the intestines of humans and animals. It is important to recognize that while most strains of E. coli are harmless, some can cause serious food poisoning and other illnesses.

**Hint:** E. coli is primarily associated with the intestines of warm-blooded organisms.

### Step 2: Identify the source of E. coli in water
E. coli is released into the environment through fecal matter. When there is a high amount of E. coli in water, it often indicates that the water has been contaminated with fecal material from humans or animals.

**Hint:** Think about how waste products can enter water sources.

### Step 3: Link E. coli presence to water quality issues
The presence of E. coli in water is a strong indicator of sewage contamination. This means that the water may have been mixed with sewage, which can contain various pathogens and harmful substances.

**Hint:** Consider what sewage contains and how it affects water quality.

### Step 4: Conclude the implications of E. coli presence
When E. coli is detected in water, it suggests that the water is not safe for consumption and indicates pollution, specifically sewage pollution. This can lead to various health risks due to the potential presence of disease-causing germs.

**Hint:** Reflect on the health risks associated with contaminated water.

### Final Answer
