Haridwar's environment is defined by its position where the Ganges exits the Himalayas and enters the Indo-Gangetic plains.
* **Air Quality:** Generally moderate, but it can drop to poor categories during winter months or massive vehicular influxes during festivals. SIDCUL industrial area emissions are monitored by the state pollution board. * **Water Quality (The Ganges):** The city is a major focal point for the Central Government's *Namami Gange* project. Multiple new Sewage Treatment Plants (STPs) have been installed to prevent untreated waste from flowing into the river. The water is fast-moving and heavily aerated, which aids its natural purification. * **Flora and Fauna:** Haridwar borders the **Rajaji National Park**, a crucial tiger and elephant reserve. Wildlife corridors are protected, though human-animal conflict (especially with elephants) occasionally occurs on the city fringes. * **Sustainability Bans:** The city has strict bans on single-use plastics and polythene bags, particularly enforced near the river ghats. Being a holy city, meat and alcohol are strictly prohibited, significantly influencing the local ecological and urban footprint.
