Since the Clean Water Act, 2006 was adopted within the province the original recommendations of the [http://www.archives.gov.on.ca/en/e_records/walkerton/index.html "Walkerton Inquiry"] were able to begin to be implemented. The legislation required municipalities protect their drinking water sources and supplies through prevention by developing collaborative large-scale watershed-based source protection plans or source water protection (SWPP) based on monitoring results and the latest science. When the Clean Water Act was first established the province paid for the cost of developing the preliminary SWPPs.


{{textbox|Under the Clean Water Act the legislation describes newly developed source water protection ''areas'' and source water protection ''regions''.
{{textbox|The Clean Water Act defines source water protection ''areas'' and source water protection ''regions'' as follows:

Under the Clean Water Act, local multi-stakeholder source water protection committees have been established for each source water protection area or region. Each committee is comprised of the region's leading researchers, professionals and technical experts that work together to identify current and potential future threats to municipal drinking water sources. Organizations typically represented on source water protection committees include, but are not limited to the following:
 
* Conservation authorities;
Under the Clean Water Act local multi-stakeholder source protection committees were developed for each region. Each committee is comprised on the region's leading researchers, professionals and technical personnel that help identify significant current and potential future threats to their local municipal drinking water sources. Their job is to regularly meet and develop preventative plans to address identified and theorized threats (Lake Erie Source Protection Region, 2022)<ref>Lake Erie Source Protection Region. 2022.

Under the Clean Water Act, 2006 a total of 19 SPRs and SPA's have been established across the province. Each of these 19 SPRs/SPAs contain their own local multi-stakeholder source protection committees across the province which have developed 38 local source protection plans. These specialized plans identify various actions to protect over 450 affected municipal drinking water systems (covering 95% of Ontario's population) (Government of Ontario, 2021)<ref name="example1" />.

These plans identify various actions to protect over 450 municipal drinking water systems, servicing 95% of Ontario's population. (Government of Ontario, 2021)<ref name="example1" />.  
 
===Source Protection Plans===
A source protection plan (SPP) contains policies developed by the source water protection committee aimed at protecting existing and future sources of municipal drinking water from significant threats to both quality and quantity of the resources. Land use activities that represent threats to drinking water sources have been identified and categorized as significant when located within highly vulnerable areas or zones, such as wellhead protection areas (WHPAs) for municipal groundwater wells, intake protection zones (IPZs) for surface water sources, and significant groundwater recharge areas (SGRAs).
 
An important first step for designers and approvers of all stormwater management systems in Ontario is to determine if land use activities associated with the proposed development represent significant threats to municipal drinking water sources, and what source water protection plan and associated policies apply to the site. The Province of Ontario's [https://swpip.ca/ Source Water Protection Information Portal] provides a convenient means of screening proposals based on threat subcategory and geographic location, and identifying the source protection plan to consult for further guidance and specific policies. 
 
Based on the most current [https://threats.swpip.ca/  Drinking Water Threats and Circumstances database tool], development of stormwater treatment and infiltration facilities, outfalls and associated infrastructure, whether servicing an industrial/commercial, residential/institutional or rural development, may represent significant threats to drinking water sources when proposed within certain WHPA and IPZ areas and may need to be located outside of highly vulnerable areas or zones.  Proposed developments that include creation of paved areas that will receive road salt applications during winter may also represent a significant threat to drinking water quality in highly vulnerable areas or where source water quality issues already exist (i.e., issue-contributing areas).  Furthermore, if the proposed development involves creation of impermeable surfaces to the extent that it will significantly reduce recharge to an aquifer, stormwater infiltration facilities may need to be included. 


Ultimately, SPPs are plans to help reduce or eliminate significant drinking water threats within its associated zone/area. These drinking water threats are listed in the following and the SPPS have policies place which must also be enforced. These policies when implemented help to both manage and/or prohibit significant threats as a result of various activities to ensure that they cannot pollute or deplete necessary sources of municipal drinking water within the zone/area.
The Province of Ontario's on-line [https://www.lioapplications.lrc.gov.on.ca/SourceWaterProtection/index.html?viewer=SourceWaterProtection.SWPViewer&locale=en-CA Source Protection Information Atlas] can be used to determine what source water protection area or region a proposed development site is located within, and if it falls within a vulnerable area where source water protection policies would apply. If the proposed development site is located in a vulnerable area or zone, the current source water protection plan in place for the location should be checked and source water protection committee representative should be consulted to determine what policies apply or what protective measures will be required.

A Wellhead Protection Area (WHPA) is an area located on the ground surface that denotes a specific zone within a known aquifer where fresh groundwater flows to a pumping well. Any detrimental activities/actions that take place in this zone may contribute to pollutions that can infiltrate into the underlying soil below and in turn contaminate said groundwater source for private and municipal wells alike - hence  undertaken in this area may release pollutants that could seep into the soil and contaminate the groundwater used by both domestic and municipals wells. As a result, these areas require high levels of monitoring, protection and enforcement. Accordingly, this area warrants greater protection.

An Intake Protection Zone (IPZ) is an area that includes both land and surface water around municipalities' intake pipes that lead to a water treatment plant (WTP) and contributes to the municipalities drinking water system and sources. An IPZ on a map delineates where surface water is originating from and how it end up in the municipal water supply. These zones are determined by how far away they are from the intake location and the time it would take to reach it. The resulting size and shape of each of the three (3) zones of a typical IPZ represents either this set distance around the intake or simply the length of time it would take water and potential contaminants from overland flow to reach the intake.

==Pretreatment Features==
==BMP Selection & Pretreatment for SWP==
 
With respect to potential contaminants or pollutants in stormwater surface runoff the types and levels of these contaminants varies widely depending on the associated activities, characteristics and makeup of the local source water area.
 
[[File:Pollution hot spots.jpg|thumb|600px| Examples of activities that can lead to a source area being deemed a "Pollution hot spot" when it comes to surface runoff pollution (Photo Source: Müller et al. 2020<ref>Müller, A., Österlund, H., Marsalek, J. and Viklander, M. 2020. The pollution conveyed by urban runoff: A review of sources. Science of the Total Environment, 709, p.136125. https://www.sciencedirect.com/science/article/pii/S0048969719361212#f0010</ref>).]]
 
An area, for example that contains a high density of roads and industrial areas that require large amounts of de-icing [[salt| road salt]] in the winter and experiences heavy traffic daily, make it a significant source of sodium, chloride, petroleum based hydrocarbons and [[heavy metals]]. On the other hand a source area such as a roof is only subject to atmospheric deposition of contaminants and isn't typically subjected to vehicular traffic, sand, [[salt]] nor other de-icing agents. As a result, roof runoff typically contains significantly lower levels of [[heavy metals]], petroleum hydrocarbons, salt.
 
Certain source areas known as "pollution hot spots" have a higher chance to create contaminated surface level runoff due to given activities occurring and associated contaminant types present on site (i.e. vehicle fueling stations, landfills, certain agricultural practices, manufacturing and construction sites, etc. As a result of this different runoff contamination levels also limit the types of treatment opportunities and practices that can be implemented in varying source water areas. It is important that stormwater management plans be developed with consideration of the different types of runoff source areas that will be present, and recognition of source
areas with low to moderate contamination potential that represent opportunities for [[Rainwater Harvesting| rainwater harvesting]], [[permeable pavements]] and other stormwater infiltration practices. Furthermore, it is important to ensure that relatively clean runoff is not mixed with lesser quality runoff from surfaces that are subject to higher levels of contamination, rendering it less suitable for infiltration or harvesting.
 
A summary of stormwater source area types, associated runoff characteristics and stormwater BMP opportunities and pretreatment requirements is provided in the table below:
 
 
{| class="wikitable" style="width: 1275px;"
|+'''Types of Stormwater Source Areas, Runoff Characteristics & Opportunities for Treatment'''
|-
!<br>'''Stormwater Source Area'''
!<br>'''Runoff Characteristics'''
!<br>'''Opportunities'''
!<br>'''Principles'''
|-
|Foundation drains, slab [[underdrains]], road or parking lot [[underdrains]]
|
Relatively cool, clean water
|
Suitable for [[infiltration]] or direct discharge to receiving watercourses in the area
|
Should not be directed to stormwater management facility that receives road or parking lot runoff, so as not to mix relatively clean and contaminated runoff waters
|-
|Roof drains, roof terrace area drains, [[overflow]] from green roofs
|
Moderately clean water, contaminants may include asphalt granules, low levels of hydrocarbons and [[Heavy metals|metals]] from decomposition of roofing materials, animal droppings, natural organic matter and fall out from airborne pollutants, potentially warm water.
|
*Infiltration ([[Bioretention]], [[Enhanced swales]], [[Infiltration trenches]], [[Permeable pavements]], [[Stormwater Tree Trenches| Stormwater tree trenches]], etc.);
*Filtration ([[Bioretention]], [[Stormwater planters]], etc.);
*Harvesting with [[rain barrels]] or [[Rainwater harvesting|cisterns]] and use for both indoor and outdoor non-potable purposes (e.g., irrigation, toilet flushing) after [[Pretreatment]];
*Attenuation and treatment in [[SWM ponds|wet pond]] or [[wetland]] detention facility.
|
Runoff should be treated with a [[Pretreatment|sedimentation and/or filtration practice]] prior to infiltration. Where possible, runoff should not be directed to end-of-pipe facilities to capitalize on potential for infiltration or harvesting. Flow moderation (quantity control) prior to discharge to receiving watercourse is required.
|-
|Low and medium traffic roads and parking lots, driveways, pedestrian plazas, walkways
|
Moderately clean water, contaminants may include low levels of sediment, de-icing salt constituents, hydrocarbons, [[Heavy metals|metals]] and natural organic matter. Typically warm water.
|
*Infiltration ([[Bioretention]], [[Enhanced swales]], [[Infiltration trenches]], [[Permeable pavements]], [[Stormwater Tree Trenches| Stormwater tree trenches]], etc.);
*Filtration ([[Bioretention]], [[Stormwater planters]], etc.);
*Harvesting with [[Rainwater harvesting| cisterns]] or [[Permeable pavement]] reservoirs and use for only outdoor non-potable purposes (e.g., vehicle washing, irrigation) after pretreatment;
*Attenuation and treatment in [[SWM ponds|wet pond]] or [[wetland]] detention facility.
|
Runoff should be treated with a sedimentation and/or filtration practice prior to infiltration. Flow moderation (quantity control) prior to discharge to receiving watercourse is required. Harvested stormwater quality should be tested prior to use for non-potable purposes.
|-
|High traffic roads and parking lots
|
Potential for high levels of contamination with sediment, deicing [[salt]] constituents hydrocarbons and [[Heavy metals|metals]]. Typically warm water.
|
*Filtration after sedimentation [[Pretreatment| pretreatment]];
*Attenuation and treatment in  [[SWM ponds|wet pond]] or [[wetland]] detention facility;
*Infiltration after [[Pretreatment| pretreatment]] only where [[groundwater]] uses are limited.
|
Runoff should be treated with a sedimentation and/or filtration pretreatment practice prior to infiltration.
|-
|"Pollution hot spots" such as vehicle fueling, servicing or demolition areas, outdoor storage and handling areas for hazardous materials, some heavy industry/construction sites
|
Potential for high levels of contamination with sediment, deicing [[salt]] constituents, hydrocarbons, [[Heavy metals|metals]], and other toxins.
|
*Attenuation and treatment in  [[SWM ponds|wet pond]], [[wetland]] or hybrid detention facility;
*Potential requirement for sedimentation [[Pretreatment| pretreatment]];
*Infiltration and harvesting practices not recommended.
|
Runoff from these sources should not be infiltrated or used for irrigation. Spill containment or mitigation devices recommended contingent on size of storage facilities.
