The
Upper Segment consists of Chartiers Creek above
Wingfield Pines and from Wingfield Pines to the Millers
Run inflow. The Coal Run discharges, although visible,
are low priority because of the small impact on
Chartiers Creek, because of difficulty collecting
discharges and moving to system location, and because
the funded Wingfield project will substantially improve
the Upper Segment. |

The
Millers Run Segment consists of Chartiers Creek from the
Millers Run inflow to the backchannel inflow and Millers
Run from the Gladden discharge to its confluence with
the Chartiers (mouth of Millers Run). Impacts to
Chartiers Creek in this segment are the inflow of two
large loads of pollution. The stream is always out
of compliance with in-stream targets for Fe and Al (iron
and aluminum). There is a conspicuous change
in aesthetics in this segment.
This
priority segment is the focus of several remediation
plans. A treatment plan for the Gladden discharge
is being proposed as a deliverable for this study. The Fishing
Run project, funded by a $329,250 Growing Greener
grant, will also significantly reduce the Gladden
discharge by sealing a mine and restoring the stream
that now flows into that mine. A plan is being
developed by Stream Restoration Inc. to treat the Presto
Sygan discharge, with a $48,069 Growing Greener grant to
South Fayette Township, using the Beazer property for
the system design. |

The
Backchannel Segment consists of the Chartiers Creek
Backchannel and McLaughlin Run below the Bridgeville
Mine inflow. The Bridgeville mine discharge is a
medium priority because the discharge is highly visible
and opportunities exist for reasonably cost-effective
treatment. The Woodville treatment options also
have a medium priority because of visibility and
treatibility. |

The
Scrub/Hope Segment consists of Chartiers Creek from
Scrubgrass Run to Robinson Run. The Scrubgrass
discharge is medium priority because of existing
investment in the system, educational use of the system,
and potential to make the system more effective through
cost-effective measures. The Hope Hollow discharge
is low priority because the cost will be very high while
the impact on Chartiers Creek is currently low because
the stream is already so degraded. |

During
autumn 2004 and winter 2005, more Fe and Al (iron and
aluminum) was discharging from Robinson Run than all
discharges upstream. A Growing Greener grant was awarded
to Wanashee
Conservancy to assess these problems |
