Ambient Surface Water Quality Monitoring Schedule

Beginning in 2004 LDEQ changed from a five-year rotating monitoring cycle to a four-year cycle. This change allows for the same level of water quality monitoring over a shorter period of time. At the same time, it allows regional field staffs responsible for the sampling to more evenly distribute their monitoring workload. The four-year cycle will also permit a more balanced schedule of water quality assessments for Integrated Reporting (305(b) and 303(d)) purposes.

Within each basin, all monitored subsegments will be sampled over the year or years specified under each cycle period. Water quality assessments for the Integrated Report will be conducted for each basin following the last year of its monitoring period. Approximately 125 water body subsegments are typically monitored each month under this program.

For more information regarding Louisiana's four-year monitoring cycle please contact the Standards, Assessment and Nonpoint Source Section.
