Bench-scale survival studies with Cryptosporidium parvum were conducted in representative aquifer and reservoir waters of Florida. C. parvum inactivation rates ranged from 0.0088 log₁₀/day at 5°C to -0.20 log₁₀/day at 30°C. Temperature, surface or ground water type, and the interaction of these factors had statistically significant effects on C. parvum survival.
