Maine Surface Waters Ambient Toxics Monitoring Program SWAT 1999 to 2022

Since  the 1990s the state of Maine has compiled information on the heavy metals, organochlorines and other wastes in our state's surface waters, fresh, brackish and salt. This is the Surface Waters Ambient Toxics Monitoring Program  or SWAT.   Below are the reports from most recent 2021-2022 back to 1999 

Note: SWAT reports 2009-1999 are internet archived. DEP has chosen to remove  its early SWAT records 1999 to 2009. Those are presented below in their entirety  in their Internet Archive  "reincarnation"

While these were presented to the agency  several years ago and received with acclamations of relief  by  Swatfolk , they have not  returned these reports back onto the state's website - even though every

1999 Surface Water Ambient Toxics (SWAT) Monitoring Program Report. 1999 SWAT Report.  This report contains the results of Maine’s 1999 Surface Water Ambient Toxic (SWAT) monitoring program. Much of the data was previously summarized in a progress report published in June 2000. That report was used by the SWAT Technical Advisory Group and the DEP in review and development of the 2000 SWAT workplan. All of the data have been used as soon as received in DEP’s water quality management activities wherever appropriate.

Important Note 6/11/01: The 1999 SWAT mussels for nickel and copper are being reanalyzed. The correct data will be added when the analysis is completed.

The report is organized into 4 parts, 1 Coastal, 2 Lakes, 3 Rivers and Streams, and 4 Special Studies. Within each part, results are presented in the order of the 1999 workplan.

Questions may be directed to authors of each study or to Barry Mower, DEP, SHS 17, Augusta, Maine 04333, tel: 207-287-7777.
