# Changed the following (10/02/1997) because of previous errors and a decision to use
# an MCL where it exists:
#  Chloroethene (vinyl chloride) from a RSD5 of 1.5 ug/L to a MCL of
#  2.0 ug/L 1,2-Dibromoethane (EDB) from a RSD5 of 0.04 ug/L to a MCL
#  of 0.05 ug/L 1,2,3-Trichloropropane from a RSD5 of 50 ug/L to a HA
#  of 40 ug/L Tribromomethane from a RSD5 of 40 ug/L to a MCL of 100
#  ug/L Bromodichloromethane from a RSD5 of 6 ug/L to a MCL of 100
#  ug/L 1,1,1,2-Tetrachloroethane from a HAL of 70 ug/L to a RSD5 of
#  10 ug/L 
#  Changed the following (12/12/1997) because of USEPA
#  released the Health Advisory for MTBE.  Methyl tert-butyl
#  ether (MTBE) COMMENTS Range is now 20 - 40 ug/L.  Documentation for
#  this change is USEPA, 1997, Drinking water advisory: Consumer
#  Acceptabilty advice and health effects analysis on methyl
#  tertiary-butyl ether (MtBE): U.S. Environmental Protection Agency,
#  Office of Water, EPA-822-F-97-009, 34 pp.
#  Changed the following (01/09/1998) to reflect the MCL for total
#  trihalomethanes Added a row for the total trihalomethanes
#  (THM). Comments were added to the four trihalomethanes
#  (Bromodichloromethane, Dibromochloromethane, Trichloromethane
#  (Chloroform), and Tribromomethane (Bromoform)) to refer the user to
#  the trihalomethanes.
#  Updated 2/01/2000 to include the 33 additional analytes on Schedule 2020.
#  Updated 10/05/2000 to reflect changes in Summer 2000 Drinking Water
#     Standards and Health Advisories.
#      See updated References:
#     All THMs (bromodichloromethane, dibromochloromethane, trichloromethane, and tribromomethane) updated to 80 ug/L.
#     Updated 1,1,2,2-tetrachloroethane HAL of 0.3 ug/L
#     Updated cis- and trans-1,3-dichloropropene to reflect change in RSD5 value
#         from 2 ug/L to 4 ug/L.
