Keeping water sources free from contamination serves as the primary barrier against potential supply risks and rising treatment costs. According to Laura Runkle, president of Virginia American Water, protecting reservoirs and aquifers remains the foundational step in delivering reliable utility services. The utility currently utilizes a structured assessment program, supported by nearly one million annual tests across its research laboratories, to monitor for emerging contaminants and ensure compliance with federal standards.

Beyond technical filtration and monitoring, the company is urging residents to adopt specific habits that reduce runoff. These include utilizing permeable landscaping, opting for non-toxic household cleaning agents, and properly disposing of pharmaceuticals and hazardous materials like motor oil. Thalika Hollingsworth, the utility's program manager, noted that safeguarding water supplies requires active cooperation between private citizens and local infrastructure managers. The company, a subsidiary of the national utility giant American Water, continues to coordinate with the U.S. Environmental Protection Agency to mitigate environmental impacts across its service areas.
