What is a common consequence of inadequate chlorination contact time?

• A. Lower energy costs
• B. Increased water clarity
• C. Improper disinfection of water
• D. Decreased pH levels

Answer: (C)

Inadequate chlorination contact time can lead to improper disinfection of water because chlorine needs a specific amount of time to effectively kill pathogens and microorganisms present in the water. When the contact time is insufficient, the chlorine may not have the opportunity to react with and destroy harmful bacteria, viruses, and protozoa. This failure to achieve adequate disinfection can pose serious health risks to consumers, as untreated or poorly treated water may lead to the spread of waterborne diseases. Ensuring the proper contact time is crucial for the effectiveness of chlorination in water treatment processes. Regarding the other options, lower energy costs are not directly related to chlorination contact time, as energy consumption is influenced by various factors. Increased water clarity is often a result of effective treatment processes, but inadequate chlorination could actually lead to turbid water if contaminants are not properly managed. Lastly, decreased pH levels can occur for other reasons in water treatment but are not a direct consequence of insufficient contact time for chlorination.
