When drafting regulations for a wastewater system, an REHS should consult with which organization?

The most appropriate organization to consult when drafting regulations for a wastewater system is the National Ground Water Association (NGWA). The NGWA is dedicated to the promotion of sustainable groundwater practices and the use and protection of groundwater resources, which is highly relevant to the context of wastewater management. Their expertise encompasses the interaction between wastewater systems and groundwater quality, making them an essential resource for establishing sound regulations that safeguard both human health and the environment.

When developing wastewater regulations, it is crucial to consider the impact on groundwater, as improper wastewater management can lead to contamination of groundwater supplies, which are vital sources of drinking water. Consulting with the NGWA ensures that regulations are informed by the latest research and best practices in groundwater protection, thereby enhancing public health and environmental outcomes.

While the other organizations like the EPA, CDC, and OSHA have important roles in environmental health and safety, they focus on broader aspects such as air quality, public health, and occupational safety. Their involvement is relevant but not as directly tied to the specifics of wastewater systems and their interaction with ground and surface water. The NGWA's specialized knowledge in groundwater issues makes them the most relevant choice for wastewater regulation drafting.
