   Aldicarb Sulfoxide	Methomyl
   Aldrin	Metolachlor
   Butachlor	Metribuzin
   Carbaryl	Propachlor
   Dicamba

   Unregulated VOCs

   Bromobenzene	Dichlorodifluoromethane
   Bromochloromethane	1,3-Dichloropropane
   Bromodichloromethane	2,2-Dichloropropane
   Bromoform	1,1-Dichloropropene
   Bromomethane	1,3-Dichloropropene
   n-Butylbenzene	Fluorotrichloromethane
   sec-Butylbenzene	Hexachlorobutadiene
   tert-Butylbenzene	Isopropylbenzene
   Chlorodibromomethane	p-Isopropyltoluene
   Chloroethane	Methyl Tertiary Butyl Ether (MTBE)
   Chloroform	Naphthalene
   Chloromethane	n-Propylbenzene
   o-Chlorotoluene	1,1,2,2-Tetrachloroethane
   p-Chlorotoluene	1,2,3-Trichlorobenzene
   Dibromomethane	1,2,4-Trichlorobenzene
   m-Dichlorobenzene	1,2,3-Trichloropropane
   1,1-Dichloroethane	1,2,4-Trimethylbenzene
   	1,3,5-Trimethylbenzene

2. (2) The following are the monitoring requirements for the unregulated contaminants:

   1. (a) All community and NTNC water systems shall sample for unregulated SOCs at the same sampling point and at the same time as the initial samples are collected for the analysis of the regulated SOCs.
   2. (b) All community and NTNC water systems shall collect one sample at each sampling point for the unregulated inorganic chemicals at the same time as samples are collected for the analysis of the regulated inorganic chemicals.
   3. (c) The monitoring frequency and analytical requirements for the unregulated and regulated VOCs shall be the same.
   4. (d) Any water system required to monitor by this rule shall notify persons served by the system of the availability of the results of sampling. Results of such monitoring and notice shall be provided to the Department within 30 days of completion.
   5. (e) The Department may increase monitoring where necessary to detect variations within a water system.
   6. (f) In addition to the contaminants listed at paragraph (1) of this rule, the Department may require monitoring for other contaminants of concern in drinking water for which health advisories or toxicity values have been issued, at locations and frequencies as determined by the Department.
