The Methods and Data Comparability Board is a partnership of water-quality experts whose mission is to develop water-quality monitoring approaches that facilitate collaboration and comparability amongst all data-gathering organizations. The Board develops products that enhance our ability to achieve real environmental gains while making the best use of the limited resources available for water-quality monitoring.

The IP address is used as the default gateway for many routers. The IP addresses used to access the management interface of the modems are specific, and the most common one is and is especially used in Xfinity comcast routers.



Sensor QA (ACRR) Matrix

The Sensor QA (ACRR) Matrix is, essentially, a list of actions you can do to Affect, Check, Record, and Report the quality of your Sensors' measurements. A number of data quality aspects are addressed. The Matrix reflects the Sensors QA Workgroup’s consensus on recommendations for a minimal list of actions which will still ensure delivery of data of known and documented quality. These actions are packaged in a series of spreadsheets (tabs), each containing a dedicated Matrix, for temperature, specific conductance, dissolved oxygen (DO), pH, turbidity, depth, and oxidation-reduction potential (ORP).  We also added a generic Matrix with ACRR actions which pertain to all sensors.  Monitoring Tips are added, linked to specific actions, as part of each Matrix; the same tips are also compiled on a separate tab. Please keep in mind that the Matrix is meant to be used by field operators in conjunction with the User's Manual (for instrument-specific instructions) and with the Program's SOP.
