When it comes to ensuring the water we drink is safe, there are powerful entities that oversee the entire process. However, most people never stop to think about where their drinking water comes from or how it’s regulated. Who is responsible for making sure the water you drink every day is clean and safe? While the obvious answer might be yourself, a network of local, state, and federal agencies plays a critical role in maintaining water quality.
Today, Office H2O will explore who regulates US drinking water and how they do it. From setting strict limits on contaminants to enforcing these regulations, this article will walk you through the full process of how water is monitored and controlled in the United States. Understanding this system ensures you can always trust the quality of your home's drinking water. Let’s dive in!
**The Safe Drinking Water Act (SDWA)**
The Safe Drinking Water Act is the main law that gives the federal government authority over public water systems. Passed by Congress in 1974, this act was created during a time when growing evidence showed that industrial chemicals were contaminating public water supplies and causing serious health issues, including cancer. The SDWA empowered the Environmental Protection Agency (EPA) to establish national standards for contaminants found in drinking water.
Since its enactment, the EPA has set standards for 90 different contaminants, ranging from lead and arsenic to nitrates and other harmful substances. In 1996, the act was updated with amendments that improved the process of developing new standards and strengthened regulations on certain contaminants. Despite these improvements, some critics argue that the SDWA still falls short in protecting public health, leading to ongoing calls for further reforms.
**How Are Limits Set on Contaminants in Drinking Water?**
This section will explain how the EPA sets limits on the levels of contaminants in drinking water under the SDWA. It's important to note that this process isn’t quick—it involves several detailed steps to ensure that the water we drink is safe for everyone.
First, the EPA identifies a list of unregulated microbial and chemical contaminants that could harm human health. Water utilities then test their treated water to see if any of these contaminants are present. This testing happens every five years. Based on the results, the EPA decides whether new regulations are needed. Three key factors influence this decision:
1. Is the contaminant harmful?
2. Is it present at high levels?
3. Would regulation significantly reduce the risk?
If all three answers are "yes," a national standard is required. This process can take many years to complete. In recent decades, the EPA hasn't added many new contaminants to the list, but it has strengthened rules around arsenic, disinfection byproducts, and microbes.
**Making the Necessary Calculations**
Once a need for a standard is identified, the EPA must consider several factors. First, they evaluate the health risks associated with the contaminant. Then, they calculate the cost of treating the water to remove the contaminant. Finally, they assess whether the necessary treatment technology is widely available.
**Setting a Maximum Contaminant Level Goal (MCLG)**
After considering all these factors, the EPA establishes a Maximum Contaminant Level Goal (MCLG). This is the level at which no one is expected to become ill from long-term exposure to the contaminant. A national standard is then set as close to this goal as possible, taking into account the cost of treatment. Additionally, the EPA has 15 secondary standards that relate to the taste, color, and odor of water, though these are not mandatory for water utilities unless required by states.
**Meeting the National Standard**
As the final step, once a standard is set, all 50,000 community water systems in the U.S. must test for the contaminant. If the contaminant is found above the limit, water operators are required to treat the water to bring it back below the standard. That’s the full process of how drinking water is regulated in the United States!
