The Comox Valley Regional District is encouraging residents and visitors to think about the type of sunscreen they use this summer, saying the products we choose can have an impact on local lakes, rivers, and drinking water sources.

The CVRD says while sunscreen is an important part of protecting against the sun, many common products contain chemical UV filters that can wash off during swimming and end up in freshwater ecosystems.

Several ingredients, such as oxybenzone, octinoxate, and octocrylene, can affect the growth and survival of aquatic insects, plants, and fish that play an important role in maintaining a healthy watershed.

The district is recommending mineral-based sunscreens containing non-nano zinc oxide or titanium dioxide.

People using chemical sunscreens are encouraged to apply them at least 20 minutes before swimming to allow them to absorb into the skin, and to avoid spray-on products near streams, docks, and shorelines.

The campaign is part of ongoing efforts to protect the Comox Lake watershed, which supplies drinking water to more than 50 thousand residents.

The CVRD says its watershed protection plan recognizes that small, everyday actions can play an important role in preserving water quality.

The initiative is supported by local organizations, including the Courtenay Fish and Game Protective Association, and the Lake Park Society, which are helping raise awareness about the connection between sunscreen choices and watershed health.
