Lanham benefits from Prince George's County's initiatives to preserve green spaces and improve sustainability amidst dense suburban development.
* **Air Quality:** Air quality is generally moderate to good but can be impacted by vehicular emissions due to its proximity to the Capital Beltway (I-495) and Route 50. Ozone action days occasionally occur in the peak of summer. * **Water Quality:** Tap water, sourced from the Patuxent and Potomac rivers and treated by WSSC, consistently meets or exceeds federal Safe Drinking Water Act standards. * **Parks and Protected Areas:** The Maryland-National Capital Park and Planning Commission (M-NCPPC) maintains numerous local parks and community centers in Lanham. Greenbelt Park, a national park offering camping and trails, is located just to the northwest. * **Sustainability & Recycling:** Prince George's County mandates recycling and has banned single-use plastic bags in retail stores to reduce litter. The county also operates a robust composting facility.
