Contact:

Mike Mallonee

Data is currently being collected under the following grants: CB98361804, CB98385303, CB98382503, CB97315902, CB97322001, CB97301002

The CBP Water Quality Database is rebuilt from 5:00 AM to 6:00 AM eastern standard time. Data downloaded between these times will be incomplete.

Alert: Latitude/longitude and UTM coordinates for water quality monitoring stations were corrected July 23, 2000, 10:00 am EDT. The error occurred during the conversion to NAD83 and involved almost every station. We apologize for the inconvenience.
