Link to this table.
| General Category | Source | Action |
|---|---|---|
| Municipal Sanitary Infrastructure | Combined Sewer Overflows | Replace infrastructure, if possible |
| Sanitary Sewer Bypasses/Overflows | Line sanitary sewer pipes | |
| Inflow and Infiltration | Minimize and eliminate through repairing damaged sewers | |
| Illicit discharges from unsewered communities | Detect and eliminate illicit discharges | |
| Human Sanitary Sources | Leaky/failing septics | Update and enforce SSTS ordinances |
| Educate homeowners on septic system maintenance and opportunities for replacement | ||
| Implement higher standards for setbacks for installing septics near waterbodies | ||
| Porta-potties | Ensure construction site temporary toiles have appropriate pollution prevention BMPs | |
| Domestic pets | Dogs, cats, dog parks, walking trails, residential yard and sidewalk runoff (spring runoff after winter accumulation) | Pet waste disposal stations along trails, in dog parks, etc. |
| Pass and enforce pet waste ordinances and educate pet owners about them | ||
| Add infiltration BMPs downstream of parks/residential areas and upstream of stormwater pipes (i.e., somewhere between the park/residential area and the stormwater outfall so as to intercept and infiltrate some or all of the flow from these areas) | ||
| Reduce transport from parks, residential, and other areas by the use of buffers and other disconnection of flow pathways (e.g. impervious surface, disconnection, downspout disconnection) | ||
