Quick Answer
Homeowners should be aware of local and national regulations regarding water quality, particularly if they live in areas with naturally occurring contaminants like lead, arsenic, or bacteria. Understanding these regulations can help ensure compliance and protect public health. Proper water filtration systems are a key component in achieving safe drinking water.
Understanding Local Regulations
Local water quality regulations can vary significantly depending on the area. Homeowners should contact their local health department or water utility provider to determine the specific regulations and standards in their area. For example, the Environmental Protection Agency (EPA) sets the maximum allowable limits for contaminants in drinking water under the Safe Drinking Water Act (SDWA). In the United States, the EPA has set maximum allowable levels for over 90 contaminants, including bacteria, viruses, and inorganic compounds.
Choosing the Right Water Filtration System
When selecting a whole-house water filtration system, homeowners should consider the level of purification required to meet local regulations. Systems with a minimum of 2-3 stages of filtration, including a sediment filter, activated carbon filter, and reverse osmosis (RO) or ultraviolet (UV) light, are typically effective in removing a wide range of contaminants. For example, a system that includes a sediment filter with a micron rating of 5 microns or less can remove particulate contaminants like rust and sediment, while a UV system can kill bacteria and viruses. Activated carbon filters can remove chlorine, lead, and volatile organic compounds (VOCs).
Maintenance and Testing
To ensure compliance with local regulations, homeowners should regularly maintain and test their water filtration systems. Most systems require periodic replacement of filters, which can range from every 3-12 months depending on usage and water quality. Homeowners should also have their water tested annually to ensure that it meets local safety standards. This can be done through a certified laboratory or a local health department. By staying informed about local regulations and properly maintaining their water filtration systems, homeowners can help protect themselves and their communities from waterborne contaminants.
