Types of Wells Addressed
Old 903 Requirements:
Amended 903 Requirements:
• Did not address non-water
wells (e.g. test holes &
dewatering wells)
• Covers all wells included in OWRA
definition of “well”
• Did not address sand point
wells constructed by
homeowners

and high production wells
• Clarification of rules and exemptions
for test holes & dewatering wells
• Allows certain test holes and dewatering wells less than 3m deep to
be “shallow works” and exempt from
most requirements
• Clear requirements for jetted and
driven (i.e. sand point) wells

well must record general
information about the well
on a form supplied by MOE
• Person constructing or abandoning
a well must provide an accurate
description of the well, including:
• Location of well recorded
on only general terms, eg
lot and concession, sketch
• No tag or other identifying
markings on wells

• exact geographic co-ordinates
from GPS unit
• prepare a log of the geological
materials using simplified standard
materials list
• Placement of well tags to improve
tracking, compliance, monitoring

Categories of Drinking-Water Systems
• Municipal
– large residential (>100 private residences)
– small residential (6 to 100 private residences)
– large non-residential (e.g. airport, industrial park)
– small non-residential (e.g. community centre)
• Non-Municipal
– year-round residential (e.g. subdivision, mobile home pk)
– seasonal residential (e.g. trailer park, cottage system)
– large non-residential (e.g. industry, large school/hospital)

Treatment - Equipment
• Groundwater
–
primary disinfection capable of 99 percent removal/
inactivation (R/I) of viruses.
• Surface Water
–
chemically-assisted filtration and primary disinfection
(or equivalent) capable of 99, 99.9, 99.99 percent R/I
of crypto, giardia, viruses respectively.
• Distribution System
–
chlorination or chloramination capable of achieving
chlorine residuals of 0.2 mg/l (free) or 1.0 mg/l
(combined) throughout the system, as case may be.
All equipment to be designed/certified in accordance with “Procedure
for Disinfection of Drinking Water in Ontario”

Groundwater Under Direct Influence Of
Surface Water (GUDI)
• A GUDI system is deemed to be a surface water system
for purposes of the regulation.
• The regulation deems certain types of systems to be
GUDI based on well characteristics, type of aquifer,
distance from surface water etc.
• A deemed GUDI system can be “undeemed” if valid
reasons are presented a report written by a professional
engineer or hydrogeologist (for municipal residential
systems which require approval, Ministry must agree)
• Above report must be retained by owner for 15 years
19
19
Deemed GUDI Systems
1) Systems that obtain water from a well:
–
that is not a drilled well;
–
that does not have a watertight casing extending to a depth of 6 m;
–
for a system not capable of 0.58 l/s (50,000 l/d):
•
–
is within 15 m of surface water
for a system capable of at least 0.58 l/s (50,000 l/d):
•
•
within 100 m of surface water (overburden)
within 500 m of surface water (bedrock)
2) Systems that obtain water from an infiltration gallery
3) Systems showing evidence of surface contamination
4) Systems with report concluding that raw water is GUDI
20
20
Application for Relief from Treatment
• Only available for groundwater-based systems
• Accomplished through a condition in a Ministry approval
• System owner must conduct public consultation and
document proceedings
• Municipal residential systems require an assessment by
a Professional Hydrogeologist and Council resolution
• Systems other than municipal residential require an
assessment by a Professional Engineer (P. Eng.)
• Ministry must agree with assessment before approving
• System owner must re-apply for relief every five years
21

Source Water Protection Framework
What is Driving This?
• Part 2 Report of Walkerton Inquiry made 22 recommendations relating
to source water protection.
• SDWA regulates 4 of the 5 components of a multi-barrier approach to
drinking water protection (treatment, distribution, monitoring, response)
• Source water protection is the fifth component.
• Recognition that supply is not unlimited (climate change, growth in
southern Ontario)
• Recognition that water is undervalued (charges levied on timber or
minerals on Crown land)
25
25
Source Water Protection Framework
White Paper Consultation on source water
protection held for public and stakeholders across
Ontario in March, 2004 to consult on:
• proposed legislative approach
• enhanced management of water taking
• charging for water
26
26
Proposed Source Protection Legislation
• Key components of legislation may include:
–
–
–
–
27
watershed-based source protection plans (terms of
reference, public/stakeholder input, responsibility and
oversight, approval of plans, appeals);
establishment of/amendments to watershed boundaries;
organization of watersheds into “watershed regions” to
gain efficiencies;
governance (e.g. establishment of necessary local
boards and committees).
27
Management of Water Takings
• Potential Direction:
–
–
28
enhanced notification by permit applicant to potentially
affected parties and the public;
commit to improving the science behind the assessment
of proposed water takings;
–
monitoring and reporting of water use;
–
better guidance for permit applicants.
28
Water Taking Charges
Ontario committed to charging for commercial use
• Issues:
–
–
–
–
29
trade implications?
charge variability by volume thresholds, type of
source, consumptive uses, geographic location?
exempted uses (e.g. fire protection, drinking,
livestock)?
frequency of payment?
