Which of the following can be a consequence of improper wastewater management?

1. Clogged sewage pipes

2. Reduced water quality

3. Both A and B

4. Improved aquatic life

The correct answer is: Both A and B

Improper wastewater management can lead to a variety of negative consequences, two of which are highlighted in this question. First, clogged sewage pipes occur when solid waste, grease, or other debris accumulate in the plumbing systems, leading to blockages. This not only hampers the efficient flow of wastewater but can also result in overflows or backups, posing health risks and environmental hazards. Secondly, improper handling of wastewater can significantly reduce water quality. When treatment processes are inadequate, pollutants can be released into water bodies, leading to contamination. This degradation of water quality affects not only aquatic ecosystems but also human health, as it can render water unsafe for drinking, recreation, or even agricultural use. In contrast, improved aquatic life would not stem from poor wastewater management; rather, healthy aquatic ecosystems depend on clean water sources, which are jeopardized by inefficiencies and contamination associated with improper wastewater handling. Thus, both clogged sewage pipes and reduced water quality are direct and significant consequences of inadequate wastewater management practices.
