Does a PWS have to collect unregulated contaminant monitoring samples from all the facilities listed in SDWARS/UCMR?
Only EPTDS monitoring locations are required for unregulated chemical contaminant monitoring. Additional inventory data are displayed in SDWARS/UCMR because it was populated with data from SDWIS-Fed. (SDWIS-Fed should include all facilities at the PWS.) This should ensure that any potential monitoring location is captured by SDWARS/UCMR. All of the identified facilities are not necessarily expected to be monitored. Many PWSs have Sampling Point IDs that have been defined by their State as the unregulated contaminant monitoring locations. When facilities or sampling points are omitted or incorrectly listed in SDWARS/UCMR, the PWS will need to add or correct the information in SDWARS/UCMR. Your State Drinking Water Administrator may be able to help you with this process. (See H.2 for more information.
