Explanation:

The text talks about Westford's drinking water source (Cooper River, its watershed details) and its content (naturally occurring fluoride level, how water is made safe). The first option matches this. The second option is wrong as there's no encouragement to drink more. The third is wrong as it's not just about fluoride safety but also source. The fourth is wrong as there's no mention of protecting the watershed.

Answer:

to inform residents about the source and content of Westford's drinking water
