When it comes to ensuring the water we drink is safe, there are several important entities that play a key role in overseeing this critical process. While you may not have given much thought to where your drinking water comes from or how it's regulated, it's essential to understand who is responsible for maintaining its quality and safety. From local governments to federal agencies, a network of organizations works together to protect public health through strict water regulations.
Today, Office H2O will take you through the key players involved in regulating US drinking water and explain how they ensure the water you consume daily meets high safety standards. Understanding this system helps you feel more confident about the quality of the water coming into your home. Let’s dive in!
**The Safe Drinking Water Act (SDWA)**
Enacted by Congress in 1974, the Safe Drinking Water Act was created in response to growing concerns over the presence of harmful chemicals in public water supplies. This act gave the Environmental Protection Agency (EPA) the authority to set national standards for contaminants found in drinking water. Over the years, the SDWA has been updated to strengthen these protections, with major amendments in 1996 that expanded the EPA's regulatory power.
Under the SDWA, the EPA has established standards for over 90 different contaminants, including lead, arsenic, nitrates, and other potentially harmful substances. These standards help ensure that public water systems provide clean, safe water to millions of Americans every day.
**How Are Contaminant Limits Set?**
Setting limits on contaminants in drinking water is a detailed and time-consuming process. The EPA follows a multi-step approach to determine which contaminants need regulation. First, they identify potential harmful substances that could be present in water sources. Then, water utilities test their treated water to see if these contaminants are present.
Every five years, the EPA reviews these results to decide whether new regulations are necessary. Three main factors guide this decision:
1. Is the contaminant harmful to human health?
2. Is it found in high concentrations?
3. Will regulating it significantly reduce health risks?
If all three answers are “yes,†the EPA moves forward with establishing a national standard. However, this process can take many years, and in recent decades, the EPA has only added a few new contaminants to its list.
**Calculations and Standards**
Once a contaminant is identified as needing regulation, the EPA conducts extensive calculations. They consider the health risks associated with the contaminant, the cost of removing it from water, and whether the technology to do so is widely available.
From these evaluations, the EPA sets a Maximum Contaminant Level Goal (MCLG), which represents the level at which no one should get sick from long-term exposure. A stricter standard, called a Maximum Contaminant Level (MCL), is then set based on what is achievable through treatment.
In addition to these primary standards, the EPA also sets 15 secondary standards related to the taste, odor, and appearance of water. These are not mandatory but are often used by water utilities to improve the overall quality of the water supply.
**Meeting the National Standard**
After a standard is set, thousands of community water systems across the U.S. must test for the contaminant and ensure it stays below the limit. If levels exceed the standard, water operators must treat the water to bring it back to acceptable levels.
This entire process ensures that the water you drink is continuously monitored and protected, giving you peace of mind about its safety.
