EPA Testing Standards & Health Guidelines

---

The EPA sets legally enforceable standards for drinking water contaminants known as Maximum Contaminant Levels (MCLs) under the National Primary Drinking Water Regulations (NPDWRs). These standards are designed to protect public health by limiting the levels of contaminants in drinking water. 

The EPA not only sets these standards but also enforces them, determining what constitutes a “safe” level of contaminants.

However, it’s important to note that these MCLs are often higher than the levels recommended by other health organizations and guidelines. This discrepancy can occur for several reasons:

• Balancing Health and Feasibility: The EPA considers both health risks and the feasibility of achieving certain contaminant levels with current technology and economic constraints. This means that while lower levels might be ideal for health, they may not be practical or affordable for all water systems to achieve.

• Health-Based Goals: The EPA also sets Maximum Contaminant Level Goals (MCLGs), which are non-enforceable public health goals set at levels where no known or anticipated adverse health effects occur. These goals are often lower than the MCLs because they do not take into account the limitations of detection and treatment technologies.

• Comparative Standards: Other health organizations, such as the World Health Organization (WHO) and the Environmental Working Group (EWG), may set stricter guidelines based solely on health considerations without factoring in the feasibility of implementation. These guidelines can be more stringent than the EPA’s MCLs.

• Evolving Science: As scientific understanding of contaminants and their health effects evolves, some organizations may update their guidelines more frequently than the EPA, leading to differences in recommended levels.

In summary, while the EPA’s standards aim to protect public health within practical and economic limits, other health guidelines may recommend lower contaminant levels based purely on health considerations, leading to the observed differences. 

This means that even when water systems comply with EPA standards, the levels of certain contaminants can still pose health risks. 

What Can you do?

1. Stay Informed: Regularly check your local water quality reports.
2. Use Water Filters: Invest in high-quality water filtration systems to reduce contaminants.
3. Get Your Water Tested: Have your home’s water tested by professionals to identify any specific issues.
4. Contact Eco: Call to schedule an appointment for water quality testing, filter installation or have your city report sent to you.
