Short Answer 
Rust is formed when iron undergoes oxidation in the presence of moisture and oxygen, and its presence was observed in Westfield’s water supply, giving it a reddish-brown color due to leaching from iron pipes. This can pose health risks, damage plumbing infrastructure, and affect the aesthetic quality of water, highlighting the importance of addressing rust in water supplies.
Step 1: Understanding Rust Formation
Rust is a chemical compound known as iron oxide, which is created through an oxidation reaction. This occurs when iron reacts with oxygen, typically in the presence of moisture. The process can accelerate when other compounds, such as those found in fertilizers, are present in water.
Step 2: Observing Rust in Westfield
The residents of Westfield noticed a reddish-brown substance in their water supply. This discoloration is a clear indication of rust formation. The presence of iron pipes in conjunction with the elements in the water can lead to the leaching of iron oxide, creating the reddish hue.
Step 3: Implications of Rust
Rust can have various implications, both for health and infrastructure. It is essential to address its presence in water supplies to ensure safety and maintain plumbing systems. Some potential consequences include:
- Potential health risks from contaminated water.
- Corrosion of plumbing systems, leading to costly repairs.
- Negative impact on aesthetic quality of water.
