Depending on the specific design and materials, floating covers can potentially impact wildlife in and around water bodies. While floating covers can discourage or prevent wildlife access to the contained water, additional measures are often required to minimize effects on local wildlife.
Tanks and lagoons that store wastewater should be carefully secured within fences to block wildlife access and prevent them from damaging the floating covers and drinking from unsafe water. Floating covers should be designed or colored to discourage migratory birds from investigating covered water bodies as potential rest stops.
