Florida Drinking Water Operator "B" Practice Test

Which of the following is a consequence of elevated TDS levels in water?

1. Corrosion of pipes

2. Reduced water clarity

3. Improved taste

4. Increased vegetation growth

The correct answer is: Corrosion of pipes

Elevated Total Dissolved Solids (TDS) levels in water can have several consequences, and one significant concern is the corrosion of pipes. When TDS levels rise, the ionic concentration in the water increases, which can lead to an imbalance in the water chemistry. This heightened ionic presence can cause water to become more corrosive, especially when it contains aggressive ions like chlorides and sulfates. Corrosion occurs because the dissolved solids can react with the metal pipes, leading to deterioration and the leaching of metals into the water supply. This not only poses a risk to the integrity of the infrastructure but can also affect water quality and safety for consumption. In contrast, the other options do not directly stem from increased TDS levels in the same way. Reduced water clarity is typically associated with suspended solids and other particulate matter rather than dissolved solids. Improved taste is subjective and not a guaranteed outcome, as high TDS often results in a brackish or salty taste that many people find undesirable. Regarding increased vegetation growth, while some dissolved solids like nutrients can promote growth, high TDS generally indicates salinity levels that can actually inhibit plant growth rather than enhance it. Overall, the corrosion of pipes is a direct and relevant consequence of elevated TDS
