Florida Wastewater Practice Test

What type of material is recommended for transporting samples in wastewater management?

1. Polyethylene

2. Glass

3. Metal

4. Cardboard

The correct answer is: Polyethylene

Polyethylene is recommended for transporting samples in wastewater management due to its chemical resistance and durability. This plastic material is non-reactive, meaning it will not interact negatively with the samples being transported, which is critical for maintaining the integrity of wastewater samples. Polyethylene containers also provide a lightweight and leak-proof solution, ensuring that samples can be safely moved without risk of contamination or spillage. In contrast, glass is more prone to breakage, which poses risks during transportation, especially in field conditions. While glass has good chemical resistance, it is heavier and less practical for frequent handling. Metal containers can also react with certain substances found in wastewater, which can lead to inaccurate results. Cardboard, on the other hand, is not suitable for liquid samples as it is absorbent and can deteriorate when exposed to moisture, compromising the condition of the samples. Overall, polyethylene stands out as the best option due to its practicality and effectiveness in preserving the quality of wastewater samples during transport.
