Sec. 141.12  Maximum contaminant levels for total trihalomethanes.

    The maximum contaminant level of 0.10 mg/L for total trihalomethanes 
(the sum of the concentrations of bromodichloromethane, 
dibromochloromethane, tribromomethane (bromoform), and trichloromethane 
(chloroform)) applies to subpart H community water systems which serve a 
population of 10,000 people or more until December 31, 2001. This level 
applies to community water systems that use only ground water not under 
the direct influence of surface water and serve a population of 10,000 
people or more until December 31, 2003. Compliance with the maximum 
contaminant level for total trihalomethanes is calculated pursuant to 
Sec. 141.30. After December 31, 2003, this section is no longer 
applicable.
