MS4 Program –  Monitoring

The objective of the Monitoring Program is to quantify the physical, biological and chemical characteristics of water quality in Jefferson County, identify wet weather impacts, characterize stormwater/non-point source runoff quality from discrete land uses, and support local volunteer monitoring programs.

Per interlocal agreements, the Cities of Anchorage, Jeffersontown, Prospect, Shively, St. Matthews, and KyTC pay MSD to perform the components of the Illicit Discharge Program. The City of Louisville and Jefferson County give MSD the authority to perform the Illicit Discharge Program on their behalf.

The Monitoring Program is comprised of the following program elements:

• M-1 Wet Weather Data Collection
• M-2 Land Use Characterization
• M-3 Ambient Stream Data Collection
• M-4 Volunteer Monitoring Collection
