The Division of Environmental Analysis includes the state environmental reference laboratory and the state principal drinking water laboratory. The division's primary mission is to provide technical and laboratory support to all DEP programs. Environmental monitoring data generated by the division is used for all DEP programs to: 1) make operational and programmatic decisions; 2) directly support major criminal and civil enforcement actions; 3) support investigations which result in the identification of pollution sources that then become the subject of enforcement; and 4) measure the success and environmental impact of protection efforts. The division's Laboratory Certification Program certifies commercial and municipal environmental laboratories in Massachusetts and other states for chemical and microbiological analyses of potable and non-potable water.
