GIS Mapping Completed in 2000

Outfall Inspection Techniques

• Visual Inspection

• Sampling

Outfall Inspections

• Odors

• Stains

• Color

• Foam

• Oily Sheen

• Floatables

• Impacted Vegetation

• Dry Weather Flows

Follow the Water !!!

Visual inspection can

be an efficient method

Once an outfall is identified as having a high priority

through visual inspection there are a few easy chemical

tests that may help find the source of the problem.

• Chlorine Residual

• E. Coli

• Optical Brightener Trap

• Ammonia

• Fluoride ?

Sampling

Sampling a Manhole

Ex-filtration:

Sanitary Waste Leaking into Storm

• High Ecoli levels, no floatables/solids

•May or may not have staining, odor

• Sanitary pipe above the storm

• Broken main or lateral

• Use Optical Brightener Traps

Broken Pipe Leading

to Exfiltration

Eliminating the Discharge

• Identify the source

• Notify property owner

• Investigation crew determine exact cause

• Notice of Violation

• Pursue contractor/builder if possible

• DES perform residential repair

Urban Hotspots…Source Control

Implications of an

Illicit Discharge Ordinance

• Enforcement by MS4

• Specific language prohibiting illicit

connections and illegal discharges

• Ensures access to private property

• BMP’s

•May require septic system inspections?

• Possible penalties for non-compliance

Illicit Discharge Task Group

• Coalition members….. meet monthly

• Target Priority Pollutants

• Develop Strategies, BMP’s

• Small Business Pollution Prevention

Illicit Discharges…...

…..They’re Out There
