The water department of Philadelphia draws half its water from the Schuylkill River, and half from the Delaware River. The city has three drinking water treatment plants: Baxter, Belmont, and Queen Lane. Baxter Water Treatment Plant is the largest, treating an average of 200 million gallons a day. It provides water for almost 60% of Philadelphia's population. The Belmont and Queen Lane Water Treatment plants use water from the Schuyikill River, which has a higher mineral content and is slightly harder than the Delaware River. In recent years, radioactive elements and potentially carcinogenic disinfectant byproducts have exceeded health guidelines.
