contact the us food and drug administration (fda)
contact the centers for disease control and prevention (cdc)
contact your local red cross
contact the local community water system

Explanation:

The FDA regulates food and drugs but not specifically water fluoridation. The CDC focuses on disease - related issues and may have information. The Red Cross is mainly for disaster relief and not a source for water - fluoridation information. The local community water system is directly involved in water supply and can provide the most relevant information about fluoride levels in local drinking water.

Answer:

Contact the local community water system.
