Executive Summary The purpose of this report is to provide information to several stakeholders and to satisfy the regulatory requirements of the Safe Drinking Water Act (SDWA) including the Drinking Water Quality Management Standard (DWQMS), and regulatory reporting required under O.Reg. 170/03 (Section 11 and Schedule 22) described in Appendix F and G. The Summary Report must be presented and accepted by Council by March 31st of each year. This Regulation also requires the owner to produce an Annual Report by February 28th of each year, as set out in Section 11. This report must include the following: -

Description of the system Summary of any adverse water quality reports and corrective actions Summary of all required testing results Description of any major expenses incurred to install, repair or replace required equipment

Prior to amendments made to O.Reg. 170/03 in 2006, the Annual Report had to be submitted to the Ministry of the Environment; this is no longer a requirement. As a result, the Summary and Annual Reports have been combined by Town staff into one document, which is submitted to Council for acceptance. The report is a compilation of information that helps to demonstrate the ongoing provision of a safe, consistent supply of high quality drinking water to customers located within the Town of Midland. The Town of Midland Water Services is a municipally-owned and operated water utility. The Midland Drinking Water System is a Class 3 Water Distribution and Supply Subsystem and a Class 1 Water Treatment System. The Midland Drinking Water System is required to comply with the Safe Drinking Water Act (SDWA) and Regulations as well as requirements contained in Permits to Take Water (PTTW), Municipal Drinking Water Licenses (MDWL), and Drinking Water Works Permits (DWWP). Having met the quality management system requirements of the SDWA, Midland Water Operations is an accredited Operating Authority with an up-to-date Operational Plan (OP). The OP is available upon request from the Town of Midland Water Operations office, located at 200 Bay St.

The source of Midland‘s drinking water is a series of 10 operational groundwater wells with some groundwater under the direct influence of surface water (GUDI) sources (i.e. Highway #12 Treatment System, Vindin Treatment System). The Town of Midland has approximately 5,900 fully metered water service connections, 120 kilometers of underground watermains, and a population of approximately 17,000. As the Operating Authority, the Town of Midland Water Services is annually inspected by the Ontario Ministry of the Environment and Climate Change (MOECC) for compliance with regulatory requirements. The MOECC has not yet conducted their inspection at the time of this report. From January 1 to December 31, 2017, Midland Water Services reported two Adverse Water Quality Incidents (AWQI) in the Midland Drinking Water System: the first incident involved a chemical sample collected from Hanly Treatment System. The sample was found to contain the chemical compound 2,6 dibromo-4-fluorphenol. Re-samples were collected by a Midland Water Services Operator and a MOECC Inspector and sent to their respective laboratories. The re-sample results from both laboratories did not detect 2,6 dibromo-4-flurophenol. In conjunction with the Simcoe Muskoka District Health Unit and the MOECC, all appropriate corrective actions and reporting were completed. The second incident involved Dominion Treatment System. Treated water with a free available chlorine residual below .10mg/L was produced. The problem was corrected by reprogramming the SCADA and alarms setpoints. In conjunction with the Simcoe Muskoka District Health Unit and the MOECC, all appropriate corrective actions and reporting were completed. The system is operated to meet daily, seasonal, and other operational demands (fire demands) with various combinations of supplies in operation at any given time. From January 1 to December 31, 2017, a total of 2,022,913.0 cubic metres of water was treated and pumped to the system. The average daily water demand was 5,541 cubic metres. All water was treated with sodium hypochlorite (for chlorine disinfection) and ultraviolet disinfection (UV). All water was tested and met all regulatory standards. The Town of Midland Water System is in a fit state of repair and followed best industry practices during the repair and maintenance of the system. Infrastructure review occurs regularly between Engineering and Water Services to optimize priority projects and minimize common costs. The Town of Midland maintains a robust backflow prevention program overseeing 471 facilities with 999 backflow prevention devices installed. There were no reported backflow incidents. The Town of Midland has completed this Annual & Summary Report to satisfy the regulatory requirements of the Safe Drinking Water Act, O.Reg. 170/03 (Section 11 and Schedule 22).

Introduction Purpose The purpose of this Annual Water Summary Report is to provide information to our consumers and stakeholders as well as to satisfy the regulatory requirements of the Safe Drinking Water Act, 2002 including the Drinking Water Quality Management System (DWQMS), reports to Owner, and regulatory reporting required under O. Reg. 170/03. This report is a compilation of information that helps to illustrate the ongoing delivery of safe drinking water to our customers in the Town of Midland. Scope This Annual Water Summary Report includes information pertaining to the Town of Midland’s Drinking Water System for the period of 1 January, 2017 to 31 December 2017. We are bound by provincial law to report this information to the following; - The Drinking Water System Owners (The Corporation of the Town of Midland –Mayor and Council) - Top Management (Director – Engineering/Water and Wastewater Services) - The public Drinking Water System Overview The Town of Midland distribution system consists of approximately 120 km of water mains including 5,900 customer connections serving a population of approximately 17,000. There are approximately 29 sampling stations, 561 fire hydrants and 1,046 valves and other appurtenances within the distribution system. The distribution consists of four pressure zones (four main pressure zones, East, West, Lescaut, and Harbourview areas), four Booster Pumping Stations (Dominion, Everton, Montreal, and Penetanguishene) as well as five above ground storage facilities (Hanly Tower, Dominion Tower, Montreal Tank, Everton Tank, and Wilson Tank) with a total finished water storage capacity of approximately 14,834 cubic metres. No storage exists within the Lescaut Pressure Zone which relies upon pumped storage supplied from the Hanly Tower. Treated water is also supplied across the Wye River in two places to non-residential consumers in Tay Township - namely Martyrs' Shrine and Sainte-Marie among the Hurons, which in turn supplies the Wye Marsh Wildlife Centre. Legislation Since the issuance of the Walkerton Reports I and II in 2002, many legislative and regulatory changes have occurred for those supplying drinking water in Ontario. The following are the primary pieces of legislation that have directly affected the operation of the Town of Midland water distribution and treatment system.

4|Town of Midland

Safe Drinking Water Act As recommended by Commissioner O’Connor, the government passed the Safe Drinking Water Act in 2002, which expands on existing policy and practice and introduced new features to protect drinking water in Ontario. The Act's purpose is to protect human health through the control and regulation of drinking-water systems and drinking-water testing. The Act also provides legislative authority to implement the recommendations made in Commissioner O’Connor’s Walkerton Part I and II Reports. As of August 2007, all 28 recommendations made in Part I, and all 93 in Part II have been implemented. The Act also has the benefit of gathering in one place all legislation and regulations relating to the treatment and distribution of drinking water. Parts of the Act address: -

Accreditation of operating authorities Municipal drinking water systems Drinking water testing Inspections Compliance and Enforcement

Ontario Regulation 170/03: Drinking Water Systems Regulation The Drinking Water Systems Regulation (O. Reg. 170/03) regulates municipal and private water systems that provide water to year-round residential developments. This regulation stipulates treatment equipment usage, operational checks and sampling, chemical and microbiological testing requirements, corrective actions, and reporting requirements. Amendments to O. Reg. 170/03 came into effect on June 5, 2006. The amendments are risk-based and are designed to safeguard the quality of Ontario’s drinking water, while making the regulation more workable and affordable for residential drinking water systems and systems serving designated facilities. They add clarity and flexibility to the testing and operational regimes set out in O. Reg. 170/03 and in some cases has reduced the cost of regulatory compliance. On July 26, 2007, further amendments were made requiring additional lead sampling for water distribution systems. The purpose of the new lead testing requirements is to determine whether communities have a problem with lead in drinking water at the tap. Random testing throughout the Town would provide the basis on which to initiate actions to reduce lead levels through control of lead corrosion and would provide evidence of any changes in lead levels over time. Ontario Watermain Disinfection Procedure This procedure applies to watermains that form part of the distribution system, Drinking Water Works Permit (DWWP) Schedule B, Condition 2.3 (“DWWP Condition 2.3”) requires that all parts in contact with drinking water which are: -

Added, modified, replaced, extended; or Taken out of service for inspection, repair or other activities that may lead to Contamination, shall be disinfected before being put into service in accordance with the provisions of AWWA C651 – Standard for Disinfecting Water Mains or an equivalent procedure.

5|Town of Midland

For the purpose of DWWP Condition 2.3, this document is considered by the Ministry of the Environment and Climate Change as the equivalent procedure which replaces ANSI/AWWA C651 – Standard for Disinfecting Water Mains with respect to cleaning, tapping, maintenance and repair of watermains, appurtenances and fittings. Authorization Documents The Town of Midland owns and operates a “large municipal residential drinking water system” which has been provided the drinking water system number of 220001156 by the Ministry of the Environment. The Ministry has issued the following authorization documents for the Midland Drinking Water System; -

Drinking Water System License #122-101 Drinking Water System Permit #122-201 Drinking Water System Operational Plan #122-401

Ontario Regulation 128/04: Certification of Drinking-Water Operators and Water The Water Operator Certification Program was initiated for drinking water operators in 1987 as a voluntary program. On May 14, 2004, O. Reg. 128/04 was issued, increasing the requirements for drinking water operator’s certification. The regulation also establishes ongoing training requirements for these operators. Details note the different types of licenses, reissuance and transferability, overall and operator in charge responsibilities, record keeping, and operations/maintenance manuals. Of special note, this regulation stipulates that all new water operators must complete an Entry-Level Course of Study within the first 16 months of obtaining their operator-in-training (OIT) certificate. As of August 1, 2005, these operators must complete a 40 hour at-home study manual and successfully pass a written test based on this manual. After this, they must attend a five day in-class training seminar and examination facilitated by the Walkerton Clean Water Centre. Once these requirements have been met, the new operator’s license is valid for three years, allowing them time to meet the requirements needed for a Level One License. Drinking Water Quality Management Standard (DWQMS) On November 28, 2005, The Ontario Ministry of the Environment posted the Drinking Water Quality Management Standard (DWQMS) on the Environmental Registry for comment until January 27, 2006. On October 30, 2006, the finalized standard was issued on the Environmental Bill of Rights Registry. The purpose of this Standard is to assist owners and operating authorities in the effective management and operation of their municipal residential drinking water systems. This Standard outlines requirements for a Quality Management System (QMS) to ensure high quality drinking water. In the development of a QMS, the Operating Authority must create an Operational Plan; this document will define the QMS and will be subject to external audits for accreditation. As referenced in the Standard, the QMS must be embraced by all those with active rolls in the water system, from front line staff to the highest level of management. Town Staff have developed and implemented a QMS specific to the Town of Midland. The developed Operational Plan was submitted to the Ministry of the Environment by the imposed deadline with external auditing and final accreditation by NSF for full-scope DWQMS certification. Recertification occurred on December 16, 2016. 6|Town of Midland

Ontario Regulation 435/07: Financial Plans In 2007, the Ministry of the Environment (MOE) developed the Financial Plans Regulation (O. Reg. 453/07) under the Safe Drinking Water Act (SDWA) that prescribes the requirements for Financial Plans. The Financial Plans Regulation requires all owners of municipal residential drinking water systems to prepare Financial Plans that detail the system’s financial information projected forward for at least six years. The Financial Plans must include income statements (which set out revenues and expenses), as well as balance sheets (which include financial assets, non-financial assets, total liabilities, cash flow, etc.). The Financial Plans must then be formally approved by the Owner of the municipal system through a resolution of the Municipal Council. The Financial Plan requires regular updates before every license renewal application (every 5 years). This report formed the foundation for the Financial Plan that was then submitted to the Ministry of the Environment prior to the July 2010 deadline. This is a legal requirement under O. Reg. 453/07 and is to be resubmitted to the Ministry as a part of the Operator License Renewal Program under the DWQMS.

Wells 7A & 7B Raw Water Source Groundwater Supply | GUDI | In-Situ Filtration | Well 7A Raw Water Well #7A is located at the southern boundary of the Town of Midland along Highway #12 (Heritage Drive). This well, constructed in 1972 (Well Record #5707896), is drilled to a depth of 64.9 meters, and has a 300 mm diameter steel casing. The well is screened from 56.7 to 64.9 meters and is located within the pump house equipped with a submersible pump. Groundwater is directed to treatment equipment at the Highway 12 Treatment System pump house. According to the 2002 GUDI Hydrogeological Report, Wells 7A and 7B are located within the 50 day horizontal travel time from a pond and drainage ditches which collect runoff from Highway #12. The report further states that given the "absence of aquitards, the location of the well field in a major recharge area, and the gradual increase of sodium and chloride, suggests potential susceptibility of the aquifer to contamination and provides enough evidence to suggest that wells 7A and 7B are potentially GUDI wells as per the MOE Terms of Reference”.

Well 7B Raw Water Well #7B, located at the southern boundary of the Town of Midland along Highway #12 (Heritage Drive), was constructed in 1989 (Well Record #5709697), approximately 9 meters north of the pump house and 30 meters south of Highway #12. The well is drilled to a depth of 64.9 meters, has a 300 mm diameter steel casing and is screened from 56.7 to 64.9 meters. The well is equipped with a deep well submersible pump having an approximate capacity of 49 L/s at 105.5 metres TDH, and has a pitless adaptor directing groundwater to the Highway 12 Treatment System pump house. According to the 2002 GUDI Hydrogeological Report, Wells 7A and 7B are located within the 50-day horizontal travel time from a pond and drainage ditches which collect run off from Highway #12. The report further states that given the "absence of aquitards, the location of the well field in a major recharge area, and the gradual increase of sodium and chloride, suggests potential susceptibility of the aquifer to contamination and provides enough evidence to suggest that wells 7A and 7B are potentially GUDI wells as per the MOE Terms of Reference."

| Sodium Hypochlorite | Ultraviolet Disinfection | GUDI | In-situ Filtration | Backup Generator | 12 Treatment System The Highway 12 Treatment System pump house, situated at the corner of Highway 12 and Beamish Road, is a direct pumping type system consisting of two (2) GUDI supply wells, 7A and 7B, and treatment works. Both pumps operate independently of each other in response to the water level in the Hanly Street elevated water tower. Water is discharged following treatment into the distribution system at system pressure. Inlet piping from each well pump consists of isolation valves, air relief valves, flow measuring devices (installed on each header) and pressure sustaining valves and discharge to waste piping. Prior to treatment, the raw water Ultraviolet Light Transmittance (UVT) is measured by a continuous on-line meter; with measurements used in determining Ultralight (UV) dosage and trended on Midland's SCADA system. The chlorine contact time necessary to complete the process of primary disinfection is provided by a dedicated section of the piping upstream of the first consumer connection. To ensure proper disinfection, continuous monitoring equipment is installed for the purposes of measuring free available chlorine residual for primary disinfection. The online analyzers are supplied with a continuous sample adequately simulating contact time. The Owner has installed a 1.2 metre length of 100 mm diameter chlorine contact simulation piping. One free chlorine residual is provided with continuous samples taken off this chlorine contact simulation pipe and measures free available chlorine residual concentration in mg/L. Treatment is also comprised of: • two (2) UV irradiation units for primary disinfection purposes • a chemical disinfection system utilizing sodium hypochlorite solution for Secondary Disinfection • one continuous, on-line turbidimeter • one standby diesel generator with a nameplate indicating a rating of 330 kW is installed within a separate room in the pump house and designed to power key components of the facility during power interruptions.

Well 15/Hanly Treatment Raw Water Source and Water Treatment Facility Groundwater Supply | Sodium Hypochlorite | Ultraviolet Disinfection | In-situ Filtration | Well 15 Raw Water Well #15 is located within a removable structure directly adjacent and attached to the Hanly treatment system pump house approximately 160 meters east of Lakeview Cemetery. The well was constructed in 1985 (Well Record #5717683) to a depth of 46.6 meters with a 200 mm diameter steel casing. The municipal groundwater source is located in a primarily residential area. A cemetery is located approximately 100 metres southwest of the well. According to the Hydrogeological reports, approximately half of the cemetery is located within the 2-year Well Head Protection Area (WHPA), with the remainder located within the 25-year WHPA. The 2002 MacViro GUDI Hydrogeological report stated that the cemetery is likely "the most significant risk to the well field" and further states that contaminants released from the cemetery could be drawn to the well field due to the continuous and long-term pumping of the well. Well 15 is not considered to be Groundwater Under the Direct Influence (GUDI) of surface water.

Percentage of Production

Hanly Treatment System The Hanly pump house is located at the southwest corner of Hanly Street and Russell Street. It houses treatment and control facilities, inlet piping and flow meter, electrical panel with motor starter, electrical heater, ventilation and associated appurtenances. Well 15 conveys water to and through the treatment works into the distribution system via a 150 mm water main based on pressures and water levels in Sector 5 and the Hanly Tower. Pressures in Sector 5 are maintained by VFD driven booster pumps. The 150 mm diameter water main reportedly has no service connections from the pump house to Hanly Street, and provides some chlorine contact time prior to the first user. Treatment and monitoring consists of: • an Ultraviolet (UV) disinfection system, • a chemical system utilizing sodium hypochlorite addition for secondary disinfection purposes, • one continuous on-line chlorine residual analyzer measuring free available chlorine residual • one continuous, on-line turbidimeter measuring in NTU's,

Distribution System Treated Water Distribution

| Class 3 Distribution System | 4 Pressure Zones | Distribution The Town of Midland distribution system consists of approximately 120 km of water mains including 5,900 customer connections serving a population of approximately 17,000 persons. There are approximately 29 sampling stations, 564 fire hydrants and 1,040 valves and other appurtenances within the distribution system. The distribution consists of four pressure zones (four main pressure zones, East, West, Lescaut, and Harbourview areas), four Booster Pumping Stations (Dominion, Everton, Montreal, and Penetanguishene) as well as five above ground storage facilities (Hanly Tower, Dominion Tower, Montreal Tank, Everton Tank and Wilson Tank) with a totally finished water storage capacity of approximately 14,834 cubic metres. No storage exists within the Lescaut Pressure Zone, which relies upon pumped storage supplied from the Hanly Tower. Treated water is also supplied across the Wye River in two places to nonresidential consumers in Tay Township - namely Martyrs' Shrine and SainteMarie among the Hurons, which in turn supplies the Wye Marsh Wildlife Centre.

Apparent Cause

Replacement/Reconstruction Replacement and reconstructions are an integral part of annual infrastructure maintenance and effective asset management. An infrastructure review is conducted annually by the appointed QMS Representatives, the Water and Wastewater Services Manager, and the Director of Engineering/Water and Wastewater Services as part of the Management Review held October 31, 2017. Methods of determining infrastructure condition include: - Previous infrastructure review reports - Staff input - MOECC compliance inspection reports - Water quality - Maintenance records - Break frequency - Infrastructure age - Customer Complaints Replacement of aging or deteriorating infrastructure is coordinated with road reconstruction projects. In 2017, some of the most significant replacements/reconstructions included: Hannah Street, College, Fourth Street. In addition to the infrastructure review, the Water Services staff provided Management with a list, comprised of items needing repair or replacement. This deficiency list was specific to the Water Services operations. A number of those items have been completed or moved to the capital budget plan. Well and Storage Tanks In 2017, two robust schedules were created to outline inspections, maintenance and rehabilitation of production wells and water storage tanks. These schedules will serve as a tool to ensure water quality and longer asset lives. Inspection schedule is built into the Operating Budget and funding has been set aside in the Capital Budget for asset rehabilitation. Water and Energy Conservation Initiatives Water is a resource we have become accustomed too. Quality water is plentiful in our area of the province. The idea of running out of water is an unimaginable idea, to most. Yet, as growing trends in climate change research suggest, this abundant resource may not always readily available. Greenhouse gases emitted as a result of energy consumption used in the treatment of water is also a concern. Energy use, water conservation and greenhouse gas emissions are all directly correlated. It is with this idea in mind; Water Services carries out water conservation methods and or best practices. Below is a list of best practice methods and programs Water Services is currently using to conserve water and reduce greenhouse gas emissions. -

Toilet Replacement Program

The program involves consumers installing a low flow toilet, completing an application, and submitting proof of purchase. Installation of low flow toilet can reduce the water consumption of an average residential home by 30%. 24 | T o w n o f M i d l a n d

-

Rain Barrel Program

One of the biggest impacts to the Town of Midland’s Water Supply during the summer months is lawn and garden watering. Rain Barrels allow the residents to store rain water for watering purposes, placing less strain on the water supply. -

Courtesy Leak Status Reporting

Modern water meters have the ability to detect leaks within a consumer’s home. Often a small consistent leak goes unnoticed. The water meter provides the meter reader with this information. The meter reader then informs the consumer. This ultimately helps reduce the amount of water used, but also reduces the consumers billing total. 145 leak status reports were generated in 2017 alone. -

Operational Best Practices

Water Operators are constantly looking for methods to reduce the amount of energy used to treat water. Below are three simple operational examples; -

Avoid peak periods – this is expensive and generates more greenhouse gas; that is when gas plants are on for electricity generation.

-

Peak demand periods coincide with the hottest days of the year. Operators are always trying to forecast filling water storage ahead of schedule

-

The inactivation process (Ultra Violet) can consume significant amounts of electricity. Monitoring proper dosage levels are key to this method of energy conservation.

Regulatory Lead Sampling Program In 2017, lead sampling program were conducted in compliance with Schedule 15.1 of Reg. 170/03 of the Safe Drinking Water Act. 37 samples were taken and submitted to Caduceon Laboratories for analysis. -

Average concentration of the 30 samples collected from residential plumbing is 0.000671667 mg/L (1st Bottle) and 0.000624667 mg/L (2nd Bottle).

-

Average concentration of the 3 samples collected from non-residential plumbing is 0.00083667 mg/L (1st Bottle) and 0.000723333 mg/L (2nd Bottle)

-

Average concentration of the 4 samples collected from distribution system sampling points is 0.0006 mg/L

Currently maximum concentration of lead expressed in milligrams per liter is 0.01mg/L, as listed in O. Reg. 169/03, Schedule 2. This limit is set to change in the near future to meet the new regulatory limits being set forth by Health Canada. The new maximum concentration is likely to be 0.005 mg/L. Results of these samples serves as sufficient evidence to indicate lead is not leaching from the existing infrastructure. 25 | T o w n o f M i d l a n d

HAAs-Haloacetic Acid Sampling On January 1 2020, Schedule 2 of O. Reg. 169/03 will include Haloacetic Acids (HAAs). Haloacetic Acids are a group of chlorinated disinfection by-products that are formed when the chlorine used to disinfect drinking water reacts with naturally occurring organic matter (NOM) in water. Some people who drink water containing haloacetic acids in excess of the maximum concentration over many years may have an increased risk of cancer. -

Monochloroacetic acid Dichloroacetic acid Trichloroacetic acid Monobromoacetic acid Dibromoacetic acid

The maximum concentration of HAAs will be 0.08 in milligrams per litre, expressed as a running annual average of quarterly results. In order to be well ahead of the regulatory changes and allow us time to make changes if necessary, preliminary samples have been collected. The results of which show we are far below the maximum concentration of 0.08mg/l. In fact tested results were 5.3 micrograms per liter or 0.0053mg/l. Future Additional Sampling More sampling for Manganese is likely going to be required. This health based standard for manganese would be a major development. The proposed federal change is due to studies, which indicate that manganese may have negative effects on cognitive abilities in children. When the Federal Guidelines for Canadian Drinking Water Quality are changed or when new guidelines are developed, the changes are normally adopted at the provincial level. In Ontario, manganese has already been established as an aesthetic objective because of taste and colour. This additional sampling will likely add cost to the already robust sampling plan.
