Boise's "Healthy" Water: The Hidden Arsenic Threat
By Franklin Everett ShawIs your tap water safe? It’s a question many Boise residents are starting to ask, and for good reason. Arsenic, a naturally occurring element, can sometimes find its way into our drinking water, posing a potential health risk. This isn’t about fear-mongering; it’s about informed action.
Boise’s water supply, primarily sourced from groundwater aquifers, faces a unique challenge. The geological composition of the Treasure Valley, particularly the volcanic rock formations, can naturally leach arsenic into the groundwater. This means that even if Boise’s water treatment facilities are operating optimally, trace amounts of arsenic might still be present in your tap water.
Understanding your water quality report is the first step. The City of Boise publishes an annual Consumer Confidence Report (CCR), often available online. Don’t just skim it; really read it. Look for the section on “Inorganic Contaminants” and specifically the listing for arsenic. The report will show the detected level of arsenic in parts per billion (ppb) and compare it to the EPA’s Maximum Contaminant Level (MCL) of 10 ppb.
If the arsenic level is below 10 ppb, the water is considered safe according to federal standards. However, remember that the MCL is a maximum level, not necessarily a safe level for everyone. Some studies suggest that even lower levels of arsenic exposure over long periods could pose health risks, especially for children and pregnant women.
So, what can you do? If you’re concerned about arsenic levels in your Boise tap water, consider investing in a water filtration system. But not just any filter will do. You need one specifically certified to remove arsenic. Look for filters certified to NSF/ANSI Standard 53 for arsenic reduction. This certification ensures that the filter has been independently tested and proven to effectively remove arsenic from water.
Finding the right filter can be overwhelming. Reverse osmosis (RO) systems are generally considered the most effective for arsenic removal. These systems use a semi-permeable membrane to filter out contaminants, including arsenic. However, RO systems can be more expensive and require professional installation. They also remove beneficial minerals from the water, which some people find undesirable.
Another option is an activated alumina filter. These filters use a special type of aluminum oxide to adsorb arsenic from the water. Activated alumina filters are generally less expensive than RO systems, but they may not be as effective at removing all types of arsenic. They also require regular replacement to maintain their effectiveness.
Before you buy, check the filter’s certification. Look for the NSF/ANSI Standard 53 mark on the packaging or product description. This is your guarantee that the filter has been tested and certified to remove arsenic. Don’t rely on marketing claims alone.
Consider the specific type of arsenic present in Boise’s water. Arsenic can exist in two forms: Arsenic III and Arsenic V. Arsenic V is generally easier to remove with filtration. Contact the City of Boise Water Quality Department to inquire about the predominant form of arsenic in your water supply. This information can help you choose the most effective filtration system.
Installation is crucial. Even the best filter won’t work properly if it’s not installed correctly. Follow the manufacturer’s instructions carefully, or hire a qualified plumber to install the filter for you. Improper installation can lead to leaks, reduced filter performance, and even contamination of your water supply.
Regular maintenance is also essential. Filters need to be replaced regularly to maintain their effectiveness. Check the manufacturer’s instructions for recommended replacement intervals. Ignoring maintenance can lead to a buildup of contaminants in the filter, which can then leach back into your water.
Beyond individual action, consider advocating for improved municipal water management practices. Attend Boise City Council meetings and voice your concerns about arsenic levels in the water supply. Support initiatives to upgrade Boise’s water treatment facilities to better remove arsenic.
One specific challenge Boise faces is the aging infrastructure. Many of the city’s water pipes are old and corroded, which can contribute to arsenic leaching into the water. Advocate for infrastructure improvements to replace these old pipes with newer, more durable materials.
Another challenge is the lack of comprehensive monitoring data. While the City of Boise publishes an annual CCR, it may not provide a complete picture of arsenic levels throughout the city. Advocate for more frequent and comprehensive water quality testing, with results made publicly available.
Consider supporting local organizations that are working to protect Boise’s water resources. Groups like the Idaho Conservation League and the Boise River Enhancement Network are actively involved in advocating for clean water policies and protecting our water supply.
Don’t fall for common misconceptions. Some people believe that boiling water will remove arsenic. This is false. Boiling water will only concentrate the arsenic, making it even more dangerous.
Another misconception is that bottled water is always safer than tap water. While some bottled water is indeed pure, others may contain contaminants, including arsenic. Check the label carefully and choose bottled water from reputable brands that have been tested for arsenic.
Remember, protecting your family’s health is paramount. By understanding the risks of arsenic in Boise’s water supply, choosing the right filtration system, and advocating for improved municipal water management practices, you can take control of your water quality and ensure that your tap water is safe to drink. This isn’t just about you; it’s about creating a healthier Boise for everyone.
