Which agency is represented by DNR in Milwaukee?

The correct answer is the Department of Natural Resources. This agency plays a crucial role in overseeing the management and protection of Wisconsin's natural resources, including air, water, and land, which are all integral to environmental health and public safety. The DNR's responsibilities extend to enforcing regulations related to lead abatement, ensuring that practices align with state environmental guidelines and promoting public awareness about lead hazards. This is particularly important in the context of lead abatement, as the DNR oversees the standards for safely managing lead-contaminated sites and protecting communities from lead exposure.

The other options either do not represent established state agencies or mischaracterize the function of the DNR, which is specifically dedicated to environmental protection and natural resource management. Therefore, the option identifying the Department of Natural Resources is absolutely appropriate in context, considering its mandate in lead abatement and overall environmental stewardship in Wisconsin.
