# Choose Your Field Investigation

Part of the Public Health Merit Badge Digital Resource Guide: [Introduction & Overview](https://merit-badge.university/merit-badges/public-health/guide/index.md)

*5. Field Investigations*

> **5.** With your parent or guardian's and counselor's approval, do ONE of the following:

You must choose exactly one option from this requirement. Both options show public health at work in the real world, but they focus on different systems and different risks.

## Your Options

- **[Req 5a — Waste and Wastewater Systems](https://merit-badge.university/merit-badges/public-health/guide/req5a/)**: Visit a wastewater treatment plant or solid-waste operation and learn how a community handles sewage or trash safely. You will see how public health protects water, soil, and people by controlling waste before it spreads disease.
- **[Req 5b — Food Safety in Action](https://merit-badge.university/merit-badges/public-health/guide/req5b/)**: Visit a restaurant, cafeteria, or similar food service facility and study how food is stored, handled, cooked, and monitored. You will learn how public health prevents contamination before a meal reaches a plate.

## How to Choose

**Choosing your investigation** — Think about what you want to observe and discuss

- [ ] **Best fit if you like systems and infrastructure**: Choose **5a**. You will see large-scale public health work that most people never notice.
- [ ] **Best fit if you like kitchens, practical routines, and daily habits**: Choose **5b**. You will study contamination control in a setting most people use every day.
- [ ] **Time and access**: A cafeteria or restaurant visit may be easier to arrange locally, while a treatment plant tour may need more planning.
- [ ] **What you will gain**: **5a** teaches how communities manage waste and protect shared resources. **5b** teaches how food safety depends on temperature, storage, sanitation, and attention to detail.

| Option | Main focus | What you observe | What you gain |
|---|---|---|---|
| **5a** | Waste systems | Disposal, treatment, sanitation, environmental protection | A bigger-picture view of how cities prevent contamination |
| **5b** | Food safety | Kitchen workflow, storage, temperatures, contamination prevention | A practical understanding of how public health protects meals every day |

> **Tip**
>
> If you have already done a lot of cooking and food handling in Scouting, 5b may feel familiar and immediately useful. If you want to see the hidden infrastructure that keeps a whole community healthy, 5a is the more eye-opening option.

You only choose one path, but both lead to the same public health lesson: prevention depends on systems people follow consistently.
