Final answer:
To reduce lead in tap water, letting the water run may not be enough. It's recommended to consult a professional, as different plumbing systems may require different actions. Taking multiple preventative measures is important for managing lead exposure.
The correct option is C) It depends on the plumbing system; consult a professional.
Step-by-step explanation:
If you are concerned about reducing lead in your tap water, letting the water run in the kitchen downstairs may not be sufficient to reduce lead in the water at other locations within the household, such as the bathroom sink upstairs. This is because if the plumbing system has been connected in a way that the water lies stagnant in pipes for a period, lead can leach from the pipes into the water. A professional can assess your home's plumbing and give you personalized advice on how to reduce lead levels in water used for drinking and cooking.
Lead poisoning is a serious health concern, particularly in older homes where lead pipes or lead-based paint may be present. Exposure to lead through drinking water can be managed by replacing lead pipes with alternative materials like iron or copper, as noted in the given exercises. However, it's important to also take preventative measures such as regularly cleaning and using water filters to minimize any potential lead exposure.
Therefore, the correct option is C) It depends on the plumbing system; consult a professional.
