**Vegas Valves: Desert Heat Breeding Copper Guts?**
By Franklin Everett ShawThe desert heat beats down, the sun glares off the Strip, and another glass of water is poured. But what if that seemingly harmless tap water is carrying a hidden risk, especially for those living in older Las Vegas homes? It’s a question worth asking, and one that could impact your health.
Las Vegas, Nevada, a city known for its dazzling lights and vibrant energy, faces a unique challenge when it comes to its water supply: aging infrastructure coupled with extreme environmental conditions. This combination can lead to elevated levels of copper in the tap water, particularly in older homes that still utilize copper plumbing. The problem isn’t just theoretical; it’s a potential health concern that deserves serious attention.
Copper leaching occurs when water corrodes copper pipes, releasing copper ions into the water supply. Several factors exacerbate this process in Las Vegas. First, the desert heat significantly increases the rate of chemical reactions, including corrosion. Second, the water chemistry in Las Vegas, often characterized by high mineral content and fluctuating pH levels, can further accelerate copper leaching. This is because the water source, primarily the Colorado River, is naturally hard and can become more corrosive depending on treatment processes and seasonal variations.
The health effects of elevated copper levels can range from gastrointestinal distress (nausea, vomiting, diarrhea) to more serious long-term issues like liver and kidney damage, especially in vulnerable populations like children and individuals with pre-existing health conditions. The Environmental Protection Agency (EPA) has established a Maximum Contaminant Level Goal (MCLG) for copper at 1.3 parts per million (ppm). While this isn’t a legally enforceable standard, exceeding this level triggers requirements for water systems to take action to control corrosion.
So, what can a concerned Las Vegas resident do? The first step is to test your tap water. Here’s a step-by-step guide:
Choose a Testing Method: You have two primary options: a DIY testing kit or a professional laboratory analysis. DIY kits are readily available at most hardware stores in the Las Vegas area, such as Lowe’s or Home Depot, and online retailers like Amazon. These kits are relatively inexpensive and provide a quick, albeit less precise, estimate of copper levels. For a more accurate and comprehensive analysis, consider sending a water sample to a certified laboratory. The Nevada State Public Health Laboratory offers testing services, as do private labs like Basic Water Company in Las Vegas.
Collect Your Sample: The accuracy of your test depends on proper sample collection. Use a clean, unused container. The best practice is to use the container provided in the testing kit or by the lab. Let the water run for at least 30 seconds to flush out any stagnant water in the pipes. Collect the sample first thing in the morning, after the water has been sitting in the pipes overnight. This will give you the highest potential reading for copper.
Follow Instructions Carefully: Each testing kit or lab will have specific instructions for sample collection and submission. Read and follow these instructions meticulously to ensure accurate results. Pay close attention to details like filling the container to the correct level and properly labeling the sample.
Interpret Your Results: Compare your test results to the EPA’s MCLG of 1.3 ppm. If your copper levels exceed this threshold, it’s time to take action. Even if your levels are below 1.3 ppm but you are experiencing symptoms that could be related to copper exposure, it’s worth investigating further.
If your water test reveals elevated copper levels, don’t panic. Several filtration options are available to address the problem.
Point-of-Use (POU) Filters: These filters are installed at specific taps, such as your kitchen sink, and provide filtered water on demand. Options include faucet filters, pitcher filters, and under-sink filters. Look for filters certified to NSF/ANSI Standard 53 for copper reduction. Brands like Brita, PUR, and Aquasana offer certified filters readily available in Las Vegas stores.
Whole-House Filters: These filters are installed on the main water line entering your home and filter all the water used in your house. While more expensive than POU filters, they provide comprehensive protection. Consider a whole-house filter with a copper reduction component, such as those offered by Culligan or Pentair.
Reverse Osmosis (RO) Systems: RO systems are highly effective at removing a wide range of contaminants, including copper. These systems typically involve multiple stages of filtration and are installed under the sink. RO systems are a good option if you are concerned about other contaminants in addition to copper.
DIY Solutions: While not as effective as dedicated filtration systems, some DIY solutions can help reduce copper levels. Flushing your pipes regularly by running the water for a few minutes each morning can help remove stagnant water that has been in contact with the copper pipes for extended periods. Using cold water for drinking and cooking can also help, as hot water tends to leach more copper.
When choosing a filtration system, consider the following factors:
Certification: Look for filters certified to NSF/ANSI Standard 53 for copper reduction. This certification ensures that the filter has been independently tested and verified to remove copper effectively.
Capacity: Consider the filter’s capacity and how often it needs to be replaced. Choose a filter with a capacity that meets your household’s water usage needs.
Cost: Compare the initial cost of the filter and the ongoing cost of replacement cartridges.
Installation: Some filters are easy to install yourself, while others require professional installation.
Beyond filtration, addressing the root cause of copper leaching is crucial. This may involve adjusting the water chemistry to reduce its corrosivity. Contact the Las Vegas Valley Water District to inquire about their water treatment processes and whether they are taking steps to control corrosion. You can also consult with a plumbing professional to assess the condition of your copper pipes and determine if any repairs or replacements are necessary. In some cases, replacing older copper pipes with PEX (cross-linked polyethylene) pipes can eliminate the source of copper contamination.
One common mistake homeowners make is neglecting to replace filter cartridges regularly. An expired filter cartridge can actually release contaminants back into the water, negating its benefits. Set a reminder to replace your filter cartridges according to the manufacturer’s instructions. Another pitfall is assuming that all water filters are created equal. Not all filters are certified to remove copper, so it’s essential to choose one specifically designed for this purpose.
Living in Las Vegas presents unique challenges when it comes to water quality. The combination of aging infrastructure, extreme heat, and unique water chemistry can contribute to elevated copper levels in tap water. By taking proactive steps to test your water, understand the risks, and implement appropriate filtration solutions, you can protect your health and ensure that the water you drink is safe and clean. Don’t wait until you experience symptoms; take control of your water quality today.
