Fig. 2. Survival of enterococci in sterile beach sand and water (colony-forming units [CFU] kg^–1 sand or CFU L^–1 water) at different temperatures (°C) at 32 practical salinity units. Solid symbols represent sand; open symbols represent water. Shapes correspond to temperature: diamonds, 20°C; squares, 30°C; triangles, 40°C. Error bars represent 1 SE (n = 3).
