What type of regulation is typically mandated by the EPA in response to high levels of lead in water?

The requirement for corrosion control treatment is based on understanding how lead can leach into drinking water from plumbing systems. When water flows through lead pipes or leads solder in plumbing, it can pick up lead particles, leading to elevated levels of lead in the water that reach consumers.

The EPA mandates corrosion control treatment as a way to mitigate this issue. This approach involves adjusting the chemistry of the water to reduce its ability to corrode pipes and thus decrease the leaching of lead into the water supply. This regulation is crucial because it proactively addresses the source of lead contamination rather than just treating the symptoms or consequences.

By focusing specifically on corrosion control, the EPA aims to protect public health by ensuring that the water supply is safe for consumption, thereby reducing the risk of lead exposure. This type of regulation is a critical component of safe drinking water practices, particularly in areas with known lead contamination risks.
