Monitoring Assessment and Standards Section

The Monitoring, Assessment and Standards Section (MASS) consists of three teams-

The Monitoring Team is responsible for the collection of water quality data for all lakes, streams, and rivers in the State of New Mexico as well as the development of Standard Operating Procedures (SOP) for data collection.  

The Standards, Planning and Reporting Team is responsible for developing water quality standards for the surface waters of New Mexico, including conducting the Triennial Review process and the development of Use Attainability Analysis (UAA) documents.  The team is also responsible for the development of the SWQB QAPP and WQMP-CPP documents.

The TMDL and Assessment Team is responsible for the development of the Comprehensive Listing and Assessment Methodology (CALM) document for determining whether the state’s waterbodies are attaining water quality standards and supporting designated uses. The results of this assessment are used for reporting through the 303(d)/305(b) Integrated List and the development of  total maximum daily load (TMDL) documents for each waterbody not meeting standards.  
Contact Kris Barrios, Program Manager, with any questions about MASS activities.
