NYC’s 2024 Water Quality Changes Could Be Silently Damaging Your Marble Surfaces

New York City’s municipal water system is undergoing significant changes in 2024, and while most residents focus on drinking water safety, few realize how these updates could be affecting their valuable marble surfaces. New York City’s vast watershed system that supplies drinking water to over 9 million people sees several important updates in 2024. From infrastructure projects to emerging contaminants, these developments have critical implications for commercial property managers overseeing buildings with heating, ventilation and air conditioning (HVAC) systems.

Understanding NYC’s 2024 Water Infrastructure Updates

To combat issues like increased downpours and droughts, NYC is implementing infrastructure upgrades making water supplies and reservoirs more resilient to weather changes. These climate fluctuations require more vigilant monitoring of water quality and frequent adjustments of chemical treatment regimens in building water systems to maintain control. Additionally, New York City Mayor Eric Adams and New York City Department of Environmental Protection (DEP) Commissioner Rohit T. Aggarwala today issued a citywide drought watch amid a historic lack of precipitation, ordering city agencies to update water conservation plans and prepare to implement them, and urging the public to help conserve every drop possible. The announcement comes as New York City concludes a historically dry October, which saw the second-longest dry streak in city records dating back to 1869.

Tighter NYC regulations focused on protecting watersheds may mandate upgrades across city properties, like backflow preventers, enhanced meters, or even different chemical treatment systems. Additionally, the city’s expanded green infrastructure pushes sustainable water practices that buildings can incorporate such as rain gardens, green roofs, natural retention ponds and permeable pavements.

How Water Quality Changes Impact Marble Surfaces

The relationship between water quality and marble preservation is more critical than many property owners realize. Marble is a metamorphic rock composed mainly of calcite, which is a calcium carbonate mineral. It is this composition that makes marble particularly susceptible to damage from exposure to water and certain chemicals. When water interacts with marble, it can lead to a variety of issues, including staining, etching, and even the development of cracks and fissures. Therefore, controlling water quality parameters is crucial to preserving the integrity and appearance of marble surfaces.

The pH level of the water is one of the most critical factors to consider when using marble in fountains and showers. Ideally, the pH level should be neutral, around 7 on the pH scale. Water with a low pH (acidic) can cause etching on the marble surface, while water with a high pH (alkaline) can lead to mineral deposits and staining.

The Science Behind Water-Related Marble Damage

When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. This process is accelerated when water chemistry is not properly balanced.

While marble is often seen as durable, its slightly porous nature makes it vulnerable to water penetration, leading to potential staining, etching, and other water-related damage. Prolonged exposure to moisture can lead to efflorescence, a white residue with a powder-like consistency can develop on the surface of the marble. This residue is an accumulation of mineral salt, and it commonly occurs on marble surfaces in moist, damp areas, such as bathrooms, kitchens, or any location that has high humidity levels and is poorly ventilated.

Optimal Water Quality Parameters for Marble Protection

To protect marble surfaces effectively, specific water quality parameters must be maintained:

• pH Level: Ideally, the pH level should be neutral, around 7 on the pH scale. A pH level between 6.5 and 7.5 is generally considered safe for marble.
• Calcium and Magnesium Hardness: The hardness of water should be moderate, with calcium and magnesium levels kept in check. A general guideline is to maintain hardness levels below 100-150 ppm (parts per million).
• Chlorine and Chloramine: Chlorine and chloramine levels in the water should be minimal. You can use dechlorinated water or let tap water sit for 24 hours to allow chlorine to dissipate before using it with marble surfaces.
• Impurities and Sediments: Water should be free of impurities and sediments that could scratch the marble surface. Use filtered or purified water to prevent the presence of abrasive particles.

Preventive Measures for Property Owners

Property owners can take several steps to protect their marble surfaces from water quality-related damage:

• Sealants play a crucial role in protecting marble floors from water and stains. These protective coatings create a barrier on the surface of the marble, preventing liquids from penetrating the stone and causing damage. Sealants also help to enhance the marble’s natural luster and make it easier to clean.
• Promptly wipe up spills, especially those containing acidic liquids or harsh chemicals, to prevent etching or staining on the marble surface. Use a pH-neutral cleaner specifically formulated for marble to clean up messes safely.
• Regular water testing to monitor pH levels and mineral content
• Installation of water filtration systems where necessary

Looking Ahead: Adapting to NYC’s Water Future

With frequent supply shifts, regulations tightening, and increasing unpredictability anticipated, proactive building owners must continually adapt water management strategies. Partnering with specialized water treatment providers allows relying on experts to maximize system performance regardless of changing external conditions.

As NYC continues to modernize its water infrastructure and respond to climate challenges, property owners with marble surfaces must stay informed and proactive. It’s important to note that water quality can vary depending on your location and the source of your water supply. Regular water testing and the use of water treatment methods can help you achieve and maintain these ideal values to protect your marble surfaces effectively.

The intersection of municipal water quality changes and marble preservation represents a critical concern for NYC property owners. By understanding these connections and working with experienced professionals, you can ensure your valuable marble surfaces remain beautiful and intact despite the evolving urban water landscape.
