The Summary of survey after stopping of TRWKR (the 8th Stage)■ Impression of clearness
・The impression of clearness worsened between Asahi Bridge and Matsushige Bridge.
In this result it was confirmed that water quality was improved by TRWKR ．
■ Transparency
・The transparency decreased by 4cm ～10cm during the 8th stage (after stopping of
TRWKR) compared with the 2,4,6th stage (during TRWKR) between Sanage Bridge andJouhoku Bridge, between Asahi Bridge and Oseko Bridge.
In this result it was confirmed that the transparency was improved during TRWKR ．
■ COD
・COD increased by 2mg/l ～4mg/l during the 8th stage (after stopping of TRWKR)
compared with the 2,4,6th stage (during TRWKR) between Sanage Bridge and Jouhoku
Bridge, and between Asahi Bridge and Matsushige Bridge.
In this result it was confirmed that COD improved during TRWKR .
COD
Chemical Oxygen Demand。
: This is an index of water contamination used for sea, lakes and marshes. It is an oxygen consumption,required for oxidation of organic matter dissolved in ample water.
The higher COD, the more it is contaminated.

BubblesA frequency of bubbles increased during the
8th stage compared with the 6th stage(during TRWKR) between Sanage Bridge
and Johoku Bridge, and between Asahi
Bridge and Matsushige Bridge. It is
expected that, the sludge of bottom of ariver, one of the cause of bubbles, wasdecreased during TRWKR.

Smell•On the 8th stage, smell between Asahi
Bridge and Matsushige Bridge was
improved:, and smell between Matsushige
Bridge and Oseko Bridge was deteriorated,compared with the 6th stage (during
TRWKR).
• It is impossible to analyze the reason why
smell between Asahi Bridge and Matsushige
Bridge was improved during the 8th stage,
with current data.

Water Colors• The water colors of “pale brown yellow
green”, “brown yellow green”, and “browngreen” frequently appeared.
• A distinct difference compared with theterms of TRWKR (between the terms of
TRWKR and no TRWKR) was not confirmed.

Garbage•Floating garbage (artificial garbage)
Plastic garbage was a lot. The ratio was
50%. Also paper garbage tends to be
increased.
•Street garbage (artificial garbage)
Plastic garbage and cigarette butts were alot. However, plastics was decreased andbutts was increased.

Living things•Many sesame (crab) appeared around
Nayabashi Bridge this year from April to
November.
•Japanese mitten crab appeared around
Nayabashi Bridge from the middle of
October to the middle of December. It is
expected that they come for laying eggs.
•After the 8th stage, Indian porpoise cameto Horikawa River.
