The Current State of Water Quality: A Sobering Reality
Before we dive into the depths of water filtration systems, let’s take a moment to understand the current state of our water supply. According to the Environmental Protection Agency (EPA), more than 90% of water systems in the United States meet all applicable health-based drinking water standards. While this statistic may seem reassuring, it’s important to note that “meeting standards” doesn’t necessarily mean the water is free from all contaminants or optimal for consumption.
In fact, a 2017 report by the Natural Resources Defense Council found that nearly 77 million Americans were served by water systems that violated federal protections that year. These violations ranged from failure to properly test water to exceeding limits on contaminants like arsenic, lead, and copper. This sobering reality underscores the importance of taking control of your home’s water quality through effective filtration.
The Vital Importance of Water Filtration Systems
Water filtration systems play a crucial role in ensuring the health, safety, and enjoyment of your household water supply. These systems offer several key benefits that make them an essential consideration for any homeowner:
