Monitoring & Assessments
Available Results and Reports
The City's stormwater program produces a variety of monitoring results and reports. They are categorized as follows:
Goal & Purpose
One of the six minimum measures of an MS4 program is Illicit Discharge Detection and Elimination (IDDE).
The goal of IDDE is to locate non-stormwater discharges – particularly chronic discharges – entering the storm drain system and to eliminate them. It is not uncommon to find that older buildings plumbed wash waters and such to a storm drain, which from there entered a stream. It’s also not uncommon to find regular washing outdoors that drains the wash water to storm drains.
Types of Innocuous Waters
There are a number of innocuous, non-stormwater discharges that may be discharged to the storm drain, but otherwise non-stormwater discharges are restricted from entering storm drains. Some of the innocuous waters are:
Our screening activities are periodic only, and so we must rely on reports from you – citizens – and from other city staff to find non-stormwater discharges. Call us if you see wash waters being discharged into or toward storm drains at 615-848-3200.

Dye tracing studies are performed in order for city staff, planners and engineers better to understand the interconnections between surface waters and groundwater.
Other special studies will include watershed characterizations – including hydrologic modeling, stream determinations, and assessments.
- The Tennessee Department of Environment and Conservation maintains an interactive map showing results of recent stream assessments and related surface water quality information.
- The United States Geological Survey maintains stream flow data and stream chemistry.
- The City of Murfreesboro collects stream quality information. A map of stream impairments in the Murfreesboro area is available.
