An chlоrinаted sоlvent hаs been releаsed in a drinking water reservоir. An environmental team measured the pollutant concentration in the water at 10.5 mg/L on day 1 and 5.7 mg/L five days later (time = 5 days). Assuming a first-order kinetics for TCA elimination, calculate the half-life of the TCA in water. Estimate how long it will take for TCA in water to reach 0.02 mg/L, a safe drinking water value.
