Surface Water Quality

Clean Water Act 303(d)/305(b) Integrated Report

The CWA §303(d)/305(b) Integrated Report (IR) is designed to satisfy the statutory requirements of Section (§) 303(d) and the reporting requirements of §§ 305(b) and 314 of the federal Water Pollution Control Act (33 U.S.C. 1251) commonly known as the Clean Water Act (CWA).  It is also designed to serve as a source of basic information on water quality and water pollution control programs in New Mexico.  Accordingly, the intended audience includes but is not limited to the general public, stakeholders, interest groups, consultants, state legislators, governmental agencies at all levels, as well as universities and other educational entities.  The Comprehensive Assessment and Listing Methodology (CALM) explains how New Mexico assesses surface water quality data against our most current water quality standards (20.6.4 NMAC) to determine attainment. 

Contact Lynette Guevara, Assessment Coordinator, with any questions or for additional details.
