Using synthetic pond liners in a natural swimming pond can have some environmental impact, but it depends on the type of liner you choose. Materials like EPDM rubber or RPE are considered more environmentally friendly because they are durable, long-lasting, and less likely to release harmful chemicals into the water. These liners are also UV-resistant, which helps them last longer without breaking down.
However, the production of synthetic liners does use energy and resources, and they can take a long time to break down if disposed of improperly. On the plus side, choosing a high-quality liner can reduce the need for frequent replacements, making it a more sustainable option in the long run. To minimize the environmental impact, look for liners made from recycled materials or those that are recyclable at the end of their life.
