Ohio EPA Recommendations
Ongoing
Issue 8 - Contaminated Stream Sediments
Description:
Lead Organization:
The Ohio EPA has made multiple recommendations and has developed solutions to
problems involving contaminated stream sediments. For example, the NPDES permit
requires Whole Effluent Toxicity Testing for major dischargers. Others require testing
for toxic organics but not Whole Effluent Toxicity Testing unless the WWTP show that
the effluent toxicity is due to the industry. Also, the Ohio EPA requires a method of
monitoring stream networks prior to NPDES permit renewal including discharger
samples in the stream network. The results are shown in a Water Quality study. Due
to the Water Quality Study, several dischargers are examined for quality to determine
the quality of the overall stream system. This is also done in the TMDL process. The
Ohio EPA uses the water quality criteria of the US EPA to control discharges and
pollutants. Finally, the Ohio EPA enforces permits limitations and penalizes those
who do not comply.

Duck and Otter Creeks Sediment Quality Assessment Report
1999
Description:
Lead Organization:
McLaren/Hart completed an ecological evaluation of sediment chemistry data for
Duck and Otter Creeks. Ohio EPA Division of Emergency and Remedial Response
and Division of Surface Water provided sediment data collected during multiple
sampling events between 1992 and 1998. Analytical results were compiled for a total
of 189 surface and subsurface samples from 121 sample locations. Analytical
methods and the selection of chemicals for analysis differed among the various
sampling programs.

Ottawa River Hot Spot Mapping
1997
Description:
Members of the Maumee RAP Ottawa River Action Group, in particular Lee Pfouts,
mapped the hot spots of the Ottawa River based on Ohio EPA's preliminary screening
data from the Ottawa River sampling that was conducted as part of the MAOC project.
This map was published in the Toledo Blade and served as a pre-cursor to the more
formal Ottawa River Hot Spot Delineation and Risk Assessment project (also
described in this report). This map helped raise the public's awareness of local water
and sediment quality issues and helped the Ottawa River Action Group identify
potential contaminant sources.
