Question 2 - 'MCL' stands for maximum contaminant level in water quality terms. Which mineral has the highest measured average result that is still well below that mineral's MCL? (1 point) Responses Fluoride Fluoride Sodium Sodium Sulfate Sulfate Chloride Chloride Question 5 Question 3 - The pH of a substance measures the dissolved hydronium ion (H3O+) or hydrogen ion (H+) concentration. Recall these ions are comparable in that hydronium is water with an additional proton attached. From the data table for water testing, the MCL indicates an acceptable range between 6.5-8.5 for this factor. The measured average result is 7.17. Why do you think the range for the Tawas City Water Treatment Plant is different from the MCL? (1 point) Responses The measured pH falls outside of the MCL in this case. The measured pH falls outside of the MCL in this case. The Range of 6.97-7.35 is much closer to the acceptable, neutral range of consumable (or potable) water. The Range of 6.97-7.35 is much closer to the acceptable, neutral range of consumable (or potable) water. The Range of 6.5-8.5 allows the water to be only more alkaline in nature. The Range of 6.5-8.5 allows the water to be only more alkaline in nature. The Range allows the water to be only more acidic in nature.

For Question 2, without the specific data from the water quality results or MCLs for the minerals listed, I can't provide a definitive answer. Typically, however, fluoride is often found in higher average concentrations in water systems while still being below its MCL.

For Question 3, the most appropriate response would be: "The Range of 6.97-7.35 is much closer to the acceptable, neutral range of consumable (or potable) water." This indicates that the Tawas City Water Treatment Plant aims for a pH that is optimal for consumption, taking into account the specific conditions of their water source.
