The tables included in the Assessment Reports in the
Thames-Sydenham and Region are intended to explore the
types of activities which are or would be significant
moderate or low threats and the circumstances which
would result in the activity being a significant,
moderate or low threat. Other resources are available
to aid in exploring those activities and the risks
associated with the activities. The table below
summarizes the tools to explore activities, the
circumstances associated with the activities and the
risks associated with activities.

| Provincial
Tables of Drinking Water Threats |
The province developed tables
of drinking water threats which are posted on
the MOE website. These tables include:
- the prescribed activities that can be
identified as threats,
- the vulnerable areas where those activities
can be identified as threats,
· the circumstances which make them threats, and
the level of risk that the threat poses based on
the above details. |

| Activities
which are threats by vulnerable area |
The rules require that the
assessment reports identify the activities which
would be threats and the areas where they would
be considered significant, moderate or low
threats. These should be used in conjunction
with the maps related to Section 7 – Threats and
Risk Assessment and the tables included on those
maps. Those maps identify the areas where
activities are or would be significant moderate
or low threats. The tables are created for a
specific vulnerable area and vulnerability and
indicate whether the activity would pose a
significant, moderate or low risk. The tables
are numbered based on the appendix that they are
contained in (A10), the series (1), the
vulnerable area (I2 for IPZ-2, WB for WHPA-B),
and the vulnerability score (4.6) (eg.
A10-1-I2-4.6 would indicate the activities which
would be threats in and IPZ-2 with a
vulnerability score of 4.6). The tables are
included in the pdf file in alpha-numeric
order. Separate files have been created for
each Source Protection Area (and its Assessment
Report). |

Circumstance Tables |
To determine the circumstances which would
result in an activity being significant,
moderate or low, one can refer to the provincial
tables of drinking water threats discussed
above. The province has also developed
individual tables which list the activities and
the circumstances which result in a significant,
moderate or low risk for a specific type of
vulnerable area and with a specific
vulnerability score. There are 76 tables many
of which are close to or more than 50 pages. As
such they have not been included in the
Assessment Reports, but are available on this
web site. |

Interactive Threats Tool |
An interactive threats tool has been
developed to search, query and filter the
threats tables. This tool is based on the
lookup tables which the province utilized to
develop to the tables of drinking water
threats. This tool continues to be refined and
updated as the province issues updated versions
of the lookup tables. It is provided “as is-
with no warranty as to its accuracy or
completeness” to allow the user to explore the
activities and the circumstances around those
activities and determine the potential level of
risk that would result in that area. As the
work is continually being updated and improved
it is important to refer to the official version
of the tables of drinking water threats to
confirm the results from the threats tool. |
