Monitoring & Assessments
Available Results and Reports
The City's stormwater program produces a variety of monitoring results and reports. They are categorized as follows:
- Annual reports to the State Department of Environment and Conservation - uses a form provided by TDEC to be submitted by September 30 for the previous reporting year (July – June)
- Illicit discharge screening - results of annual investigations to find non-stormwater discharges entering the city’s storm sewer system
- Special studies - such as bacteria sampling and dye tracing
- Status of water quality - the state’s online assessments and any local water quality reports
- Stream monitoring - results of local visual assessments and chemical and biological sampling
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:
- Air conditioning condensation
- Firefighting activities
- Groundwater infiltration to storm drains
- Landscape irrigation or lawn watering with potable water or re-purified water
- Non-commercial washing of vehicles
- Other uncontaminated water sources
- Swimming pools (if dechlorinated)
- Water line flushing or other potable water sources
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.

Special Studies
Dye tracing studies are performed in order for city staff, planners and engineers better to understand the interconnections between surface waters and groundwater.
- Maney, VA Hospital, Bushman, Lufkin Springs
- York, Garrison, Bushman, Black Fox Springs
- Three Rivers, Barfield, Tuma Springs
- Watersheds, Murfreesboro Urban Growth Boundary
- Dry Weather E. Coli Spring Sampling
- Professional Biological Samping (SQSH Samping)
- 2015 Murfreesboro Dye Trace Report
Other special studies will include watershed characterizations – including hydrologic modeling, stream determinations, and assessments.
Resources
- 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.
