City wastewater treatment achieves chemical-free status but faces challenges in water treatment

The Nashville Metro Council's recent budget hearings highlighted significant advancements in the city's water treatment processes, particularly in the move towards reducing chemical usage. During the discussions, officials confirmed that while the wastewater treatment facilities have successfully eliminated chlorine gas, achieving a completely chemical-free water treatment system remains unattainable.

City representatives explained that certain chemicals are essential for effective water treatment. For instance, coagulants are necessary to help dirt particles clump together, and powdered activated carbon is crucial for maintaining water quality. Without these treatments, residents could face unpleasant tastes and odors in their drinking water, which would likely lead to public dissatisfaction.

The council emphasized that while the water treatment plants cannot eliminate all chemicals, they have made strides in safety and efficiency. Instead of chlorine gas, the facilities now utilize sodium hypochlorite, produced on-site from restaurant-quality salt, to disinfect the water. This method not only enhances safety but also aligns with the city's long-term goals of improving water quality.

The discussions underscored the importance of balancing public health needs with environmental considerations. As Nashville continues to invest in its water services, the focus remains on ensuring safe, clean drinking water while exploring innovative treatment methods. The council's commitment to these improvements reflects a proactive approach to addressing community concerns about water quality and safety.
