Boise's Bottled Water: Plastic Chemicals Brewing?
By Franklin Everett ShawImagine reaching for a refreshing bottle of water after a long hike in the foothills surrounding Boise, only to wonder if that sip is doing more harm than good. The plastic bottle, baking in the Idaho sun, might be leaching chemicals into your drink. It’s a valid concern, and one that deserves a closer look, especially for those of us who call Boise home.
Let’s dive into the murky waters of bottled water safety, specifically focusing on what’s happening with brands sold right here in Boise.
The core issue is plastic. Many water bottles are made from polyethylene terephthalate (PET), which can leach chemicals like antimony and phthalates, especially when exposed to heat or prolonged storage. While PET is generally considered safe for single use, repeated exposure to heat, like in a car during a Boise summer, can accelerate this leaching process.
So, which brands are potentially problematic in Boise? Unfortunately, there’s no single, definitive list based on independent lab tests conducted specifically on water bottles sold in Boise. However, we can extrapolate from broader studies and apply them to what’s available locally.
For example, a 2010 study published in Environmental Science and Pollution Research found that antimony levels in bottled water increased when stored at high temperatures. This is particularly relevant in Boise, where summer temperatures can easily soar, turning car interiors into ovens. Common brands like Dasani (owned by Coca-Cola) and Aquafina (owned by PepsiCo), both widely available in Boise grocery stores like Albertsons and WinCo, use PET bottles. While these companies adhere to FDA regulations, which set limits on chemical migration, the potential for leaching under extreme conditions remains.
A significant challenge is the lack of transparency. Bottled water companies aren’t required to disclose the specific additives used in their plastic, making it difficult to assess the full risk. Furthermore, independent testing is expensive and time-consuming, which is why localized data is scarce.
However, there are steps you can take to mitigate the risk.
How to Minimize Chemical Leaching: A Boise Resident’s Guide
Choose BPA-Free Bottles: Look for bottles explicitly labeled “BPA-free.” While PET itself doesn’t contain BPA, some manufacturers use BPA in the lining of bottle caps or in other types of plastic bottles. Check brands like Evian, often found at Boise Co-op, which uses PET but emphasizes its commitment to BPA-free packaging.
Avoid Heat Exposure: This is crucial in Boise’s climate. Never leave bottled water in your car, especially during the summer. Store water bottles in a cool, dark place at home. A common mistake is leaving cases of water in the garage, which can reach extremely high temperatures.
Check the Recycling Code: Look for the recycling code on the bottom of the bottle. Codes 1 (PET), 2 (HDPE), 4 (LDPE), and 5 (PP) are generally considered safer than 3 (PVC) or 6 (PS).
Consider Alternatives: Explore alternatives to single-use plastic bottles.
- Refillable Bottles: Invest in a high-quality, reusable water bottle made from stainless steel or glass. Many local Boise stores, like REI and Whole Foods, offer a wide selection.
- Water Filtration Systems: Boise’s tap water is generally safe and meets EPA standards. Investing in a water filter, such as a Brita pitcher or a whole-house filtration system, can further improve its taste and remove any potential contaminants. You can find these at most hardware stores in Boise, like Lowe’s or Home Depot.
- Filtered Water Dispensers: Some grocery stores in Boise, like Whole Foods, offer filtered water dispensers where you can refill your own containers.
Be Wary of Old Bottles: Avoid using bottled water that has been sitting on store shelves for an extended period, especially if it’s been exposed to sunlight. Check the expiration date, although this primarily indicates the water’s taste, not necessarily its safety regarding chemical leaching.
Let’s talk about Boise’s tap water. The City of Boise Water Renewal Services provides detailed annual water quality reports, readily available online. These reports show that Boise’s tap water consistently meets or exceeds all federal and state drinking water standards. While some residents might prefer the taste of bottled water, the city’s tap water is a safe and cost-effective alternative.
One pitfall to avoid is relying solely on marketing claims. Terms like “spring water” or “purified water” don’t necessarily guarantee the absence of chemical leaching. Focus on the type of plastic used and how you store the water.
Another common mistake is assuming that all bottled water is the same. The source of the water, the type of plastic used, and the storage conditions all play a role in its safety.
For example, some smaller, local brands in Boise might source their water from natural springs in the surrounding mountains. While this doesn’t automatically make them safer, it’s worth investigating their bottling practices and the type of plastic they use.
Ultimately, the decision of whether to drink bottled water is a personal one. However, by understanding the potential risks and taking proactive steps to minimize chemical leaching, you can make informed choices that protect your health and the environment. Remember, staying hydrated in Boise’s climate is essential, but it doesn’t have to come at the expense of your well-being. Consider the alternatives, store your water properly, and stay informed.
