The Surface Water Quality Bureau - Monitoring, Assessment, and Standards Section (MASS) consists of the following three teams -
- The Monitoring Team is responsible for the collection of water quality data for all New Mexico lakes, streams, and rivers.
- The Standards, Planning and Reporting Team is responsible for developing planning documents in addition to water quality standards for the surface waters of New Mexico.
- The TMDL and Assessment Team is responsible for the development of the Comprehensive Assessment and Listing 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 Report and the development of total maximum daily load (TMDL) documents for each waterbody not meeting standards.
