Understanding BPA in Bottled Water
Cracking the Plastic Code
A Glimpse into Plastic Types and Their Health Impacts
- PETE or PET: Common in soft drinks and water bottles, PET is ideal for one-time use. But reusing can invite bacterial growth, and microwaving it? Definitely off-limits.
- HDPE: Found in items from milk jugs to toys, HDPE is among the safest plastics with minimal chemical release.
- PVC or 3V: Recognizable as a soft, pliable plastic, PVC releases two harmful chemicals. Best to find an alternative when possible.
- LDPE: While it doesn’t release chemicals into water, LDPE-packaged foods could potentially leach chemicals.
- PP: Polypropylene, a resilient plastic, is used in products like yogurt cups. Given its heat-resistant properties, it remains relatively safe.
- PS: Think disposable styrofoam cups. Heating PS releases harmful substances, making it unfit for extended food or drink storage.
- PC or ‘Other’: As a catch-all category for unmarked plastics, PC is among the riskiest. Typically containing BPA, they’re best avoided, especially in food or drink containers.
The Bottled Water Buying Guide
Check for the RIC: Located at the bottle’s bottom, this number gives insight into the plastic type.
Brand Matters: Different brands use different plastics. Research helps.
Legislation is Your Friend: Stringent laws ensure plastics are labeled accurately, aiding informed decisions.
Spotting BPA in Bottled Water
Decoding Plastic Types
1. PETE or PET:
2. HDPE (Hint: Think AquaTru):
A sturdy plastic, HDPE is found in toys, oil bottles, and your everyday milk jug. Here’s the kicker: it releases nearly zero chemicals. When shopping for bottled water, HDPE should be your first pick – it’s possibly the safest bet.
3. PVC or 3V:
7. PC or 'Other Plastics':
