Microplastics, tiny plastic particles (many of which are so small they can’t be seen by the naked eye)—have become a pervasive contaminant in water sources worldwide. You may have heard of them and, yes, researchers have identified microplastic “hotspots” in various Long Island water bodies too. Beyond the obvious concerns about potential health risks and environmental impacts, understanding this issue is crucial for Long Island residents, especially when considering water filtration solutions like reverse osmosis systems.
Understanding Microplastics
- Definition: Microplastics are small plastic fragments resulting from the breakdown of larger plastic debris or manufactured as microbeads used in products.
- Sources:
- Degradation of larger plastic waste
- Synthetic fibers from clothing
- Microbeads in personal care products
- Industrial processes
- Health Implications: Early research suggests that microplastics may harm human health by causing inflammation, oxidative stress, and disrupting cellular functions, based on findings from lab studies. Additionally, many microplastics carry harmful chemical additives like BPA and phthalates, which are known to interfere with hormone regulation and may affect reproductive and developmental health.
How Bad Is the Microplastics Problem in Long Island
Long Island draws its drinking water from underground aquifers. And, unfortunately, microplastics have been identified in groundwater samples, with concentrations ranging from 1 to 23 particles per liter. However, the concentrations are generally lower than those found in surface water like Long Island Sound, where 5,000 microfibers per cubic meter have been estimated.
The problem: Saltwater from Long Island Sound can and does seep into the underground aquifers on Long Island. This phenomenon, known as saltwater intrusion, is a significant concern, particularly in coastal areas where the aquifer is underlain by the ocean.
Limitations of Conventional Water Treatment
Standard municipal water treatment processes may not effectively remove microplastics:
- Filtration Limitations: Traditional filters may not capture particles as small as microplastics.
- Lack of Regulation: As of now, the U.S. Environmental Protection Agency (EPA) has not established enforceable standards mandating the removal of microplastics from drinking water.
Reverse Osmosis: An Effective Solution
Reverse osmosis (RO) systems offer a reliable method to reduce microplastic content in drinking water:
- Filtration Efficiency: RO systems can remove particles as small as 0.0001 microns, effectively filtering out microplastics.
- Additional Benefits:
- Removal of other contaminants like heavy metals and chemicals
- Improved taste and odor of water
- Reduced reliance on bottled water
Protecting Yourself with Simply PURE
Microplastics are an emerging concern in Long Island’s water sources, with potential health implications for residents. While municipal treatments may not fully address this issue, installing a reverse osmosis (RO) filtration system can significantly reduce microplastic content in your drinking water. At Simply PURE, we offer customized water purification solutions designed to address Long Island’s specific water quality challenges. Our systems ensure clean, safe water for drinking, cooking, and everyday use, giving you peace of mind.
