While fireworks are a tradition on the Fourth of July, they contain a number of chemicals that can impact the lake, wildlife and human health. Lead and aluminum are among the many toxic chemicals and heavy metals that are present in fireworks. These chemicals are release into the atmosphere and fall into the lake, where they can accumulate in wildlife. Older fireworks contain phosphorus, which can also negatively impact lake health. Please help to protect Squam and celebrate its quiet beauty this Fourth of July without fireworks. Learn more from the NH Department of Environmental Services fact sheet on fireworks, available here.
