Drinking Water Source Assessment for the Village of Metamora SUMMARY Source Water Assessment and Protection. The following report for the Village of Metamora was compiled as part of the Source Water Assessment and Protection Program for Ohio. This program is intended to identify drinking water protection areas and provide information on how to reduce the risk of contamination of the waters within those areas. The goal of the program is to ensure the long term availability of abundant and safe drinking water for the present and future citizens of Ohio. The Safe Drinking Water Act Amendments of 1996 established the national Source Water Assessment and Protection Program, targeting drinking water sources for all public water systems in the United States. A public water system is a facility that provides drinking water to 15 or more service connections or that regularly serves at least 25 people a day for at least 60 days a year, whether from an underground well or spring, or from an above ground stream, lake, or reservoir. The requirement does not address residential wells or cisterns. In Ohio there are approximately 5,800 public water systems. Background. The Village of Metamora operates a community public water system that serves a population of approximately 980 people. The source is surface water taken from a tributary to Ten Mile Creek. The system’s treatment capacity is approximately 220,000 gallons per day, but current average production is about 95,000 gallons per day. Protection Areas. The drinking water source protection area for the surface water source is shown in the following figure. This report includes the results of an inventory of all known or identified potential contaminant sources within the drinking water protection area. The inventory was conducted by Ohio EPA with the assistance of Rick Meiring, Superintendent of the Village of Metamora Water Treatment Plant. Possible threats to the surface water source include agricultural runoff, transportation related spills, and discharges from failing or improper home septic systems. Protective Strategies. The ultimate goal of source water assessment is implementation of protective strategies that will better protect the drinking water source. Strategies for protecting Ten Mile Creek should include controlling runoff from agricultural areas, establishment of an early warning and emergency response plan for spills, controlling home and commercial septic system discharges from failing systems, and coordination with local emergency response agencies. Ohio EPA encourages the jurisdictions within the Village of Metamora Public Water System’s protection area to develop a local protection plan to protect the source of drinking water or to update current emergency management plans as applicable. Local watershed planning efforts may already be underway to guide stream restoration and protection activities. These efforts can also serve to benefit the protection of drinking water sources. Guidance on how to form a Drinking Water Protection Team and protection plan is available from Ohio EPA by calling (614) 644-2752. For More Information. Additional information on protective strategies and how this assessment was completed is included in the detailed Drinking Water Source Assessment Report for the Village of Metamora.

How to Use this Assessment

Clean and safe drinking water is essential to everyone. Protecting the source of drinking wateris a wise and cost effective investment. The purpose of this drinking water source assessmentis to provide information your community can use to develop a local Drinking Water ProtectionProgram. The Drinking Water Source Assessment benefits your community by providing thefollowing:

A basis for focusing limited resources within the community to protect the drinking watersource(s).

The assessment provides your community with information regarding activities within theDrinking Water Source Protection Area that directly affect your water supply sourcearea. It is within this area that a release of contaminants, from a spill or improper usage,may travel through the watershed and reach the surface water intake. By examiningwhere the source waters are most sensitive to contaminants, and where potentialcontaminants are located, the assessment identifies the potential risks that should beaddressed first.

A basis for informed decision-making regarding land use within the community.The assessment provides your community with a significant amount of informationregarding where your drinking water comes from (the source) and what the risks are tothe quality of that source. This information allows your community planning authoritiesto make informed decisions regarding proposed land uses within the protection area thatare compatible with both your drinking water resource and the vision of growthembraced by your community.

A start to a comprehensive plan for the watershed and source water area.This assessment can be the beginning of a comprehensive plan for the water resource,one that addresses all of the uses the water resource provides. An ecologically healthylake, stream and watershed will provide a stable, high quality resource for drinkingwater.

1.0 INTRODUCTION

The 1996 Amendments to the Safe Drinking Water Act established a program for states toassess the drinking water source for all public water systems. The Source Water Assessmentand Protection (SWAP) Program is designed to help Ohio’s public water systems protect theirsources of drinking water from becoming contaminated.

The purpose of this assessment is to identify where and how the Village of Metamora's sourcewaters are at risk of contamination. The report• identifies the drinking water source protection area,• examines the characteristics of the watershed and the water quality,• inventories the potential contaminant sources within that area, and discusses the

susceptibility of the system to contamination.

Finally, the report suggests actions that the public water supplier and local community may taketo reduce the risk of contaminating their source of drinking water and ensure the long termavailability of abundant and safe drinking water resources.

Results and recommendations presented in this report are based on the information available atthe time of publication. Ohio EPA recognizes that additional information may become availablein the future that could be used to more accurately determine the drinking water sourceprotection area. Also, changes in land use may occur after Ohio EPA completes the potentialcontaminant source inventory. This report should be used as a starting point to develop a planto protect drinking water resources.

This report was prepared by Dana Martin-Hayden and Janet Hageman, Ohio EPA, Division ofSurface Water, Northwest District Office, and Amy Klei, Ohio EPA, Division of Drinking andGround Waters, Central Office.

2.0 PUBLIC WATER SYSTEM DESCRIPTION

The Village of Metamora operates a community public water system that serves a population ofapproximately 980 people through 361 service connections. A community public water systemis a system that regularly supplies drinking water from its own sources to at least 15 serviceconnections used by year-round residents of the area or regularly serves 25 or more peoplethroughout the entire year. The water treatment system obtains its water from a Ten Mile Creektributary. The system's treatment capacity is approximately 220,000 gallons per day, butcurrent average production is 95,000 gallons per day. Water is pumped from a Ten Mile Creektributary into two above-ground reservoirs. The Village's water treatment system consists ofcoagulation, lime softening, flocculation, sedimentation, filtration, and disinfection.

3.0 DRINKING WATER SOURCE PROTECTION AREA

The Drinking Water Source Protection Area (protection area) for an inland stream is definedas the drainage area upstream of the point where the water is withdrawn from a surface sourcesuch as a stream, lake or reservoir. The protection area is subdivided into corridor andemergency management zones. An illustration of the protection area and corridor managementzone for the Village of Metamora Public Water System is shown in Figure 1. Note that a smallportion of the protection area extends over state boundaries into Michigan. The emergencymanagement zone is shown in Figure 2.

Page 6: Drinking Water Source Assessment for the Village of Metamora · Drinking Water Source Assessment for the Village of Metamora SUMMARY Source Water Assessment and Protection. The following

The Corridor Management Zone, (CMZ), is an area along streams and tributaries within thesource water assessment area that warrants delineation, inventory, and management. Typically, this zone runs a total of ten miles upstream from the intake, and includes thetributaries that drain into it. The zone is 1,000 feet wide on each side of the Ten Mile Creektributary.

The Emergency Management Zone, (EMZ), is defined as an area in the immediate vicinity ofthe surface water intake in which the public water system operator has little or no time torespond to a spill. The boundary of the emergency management zone is delineated incooperation with the water supplier. Figure 2 shows the boundary of the emergencymanagement zone for the Village of Metamora Public Water System. The Village ofMetamora’s Emergency Management Zone (EMZ) is an area in the immediate vicinity of theTen Mile Creek tributary intake structure and the upland reservoir. This zone is defined as asemi-circle that extends 500 feet upstream and 100 feet downstream of the intake.

The corridor and emergency management zones were the focus of field and windshield surveysto inventory potential contaminant sources. Information was also collected during interviewswith water treatment plant personnel.

4.0 HYDROLOGIC SETTING

A Ten Mile Creek tributary serves as the surface water source for the Village of Metamora. TenMile Creek is approximately 34.8 miles in length with a drainage area of 113.74 square milesand flows into the Ottawa River. The water system intake is located about 1.3 miles from themainstem of Ten Mile Creek. The protection area comprises approximately 5.4 square miles. The average fall of Ten Mile Creek is 4.7 feet per mile. Annual average precipitation in theprotection area is approximately 32 to 33 inches, of which approximately 10 inches becomesurface runoff.

Figure 3 shows the land use for the protection area. The predominant land uses are row cropsat 91.1% and pasture/hay at 7% of the total protection area. The percentage cover for otherland uses include: 1.0% forest, 0.8% wetlands, 0.2% open water, and 0.1% commercial/industrial/transportation.

Drinking Water Quality Monitoring SummaryAvailable chemical and biological water quality data collected from the streams in the protectionarea, and sampling results from finished water reported to Ohio EPA by the public watersupplier were evaluated to characterize water quality. A review of the Village of Metamoracompliance monitoring data (for treated surface water) from 1991-2002 revealed that the systemhad no health based or maximum contaminant level (MCL) violations. Table 1 listscontaminants where at least one result was above the level of detection, and does not includeall contaminants tested for by the public water system. The table also includes data from theVillage of Metamora's participation in Ohio EPA’s Pesticide Special Study (1995-1999). Severalpesticides (alachlor, atrazine, simazine, metolachlor, metribuzin, cyanazine) and nitrate havebeen detected at low levels, indicating an impact from land use activities within the watershed.

It should be recognized that sampling results presented in this report can only provideinformation on the quality of the water at the time the sample was collected. Water quality maychange over time due to a number of reasons. Therefore, it is recommended that the readeralso consult the most recent Consumer Confidence Report (CCR) for the Village of Metamorapublic water system. All public water systems are required to annually prepare and distribute

the CCR to their customers. The report is a good source of information on health effectsassociated with detected contaminants and contains information on the community's drinkingwater, including the source of the water, contaminants detected, the likely sources of detectedcontaminants, and the potential health effects of contaminants at levels above the drinkingwater standards. Biological and Chemical Monitoring in Ten Mile Creek and its TributariesThere are no existing water quality data for streams within the Metamora protection area. However, two water samples were collected in 1985-86 at the mouth of an unnamed tributary toTen Mile Creek, downstream from the water intake and Metamora’s protection area. Results ofthese samples are summarized in Table 2.

Samples were also collected from Metamora Reservoir #1 in 1992-93 as part of the InlandClean Lakes Program. Reservoir sample results are summarized in Table 3. Levels of copperexceeded Water Quality Standards in all reservoir samples.

5.0 POTENTIAL CONTAMINANT SOURCES

A review of available regulated facility data bases and a field survey of the corridor managementzone indicate that two potential contaminant sources are present in the drinking water sourceprotection area. The Village of Metamora Water Treatment Plant and a farm are located withinthe corridor management zone, but outside of the emergency management zone. Also,throughout the protection area are private residences which have onsite septic systems. Thelocations of the potential contaminant sources are shown in Figure 4 and listed in Table 4.

It is important to note that this inventory represents potential contaminant sources, and includesany source that has the potential to release a contaminant to surface or ground waters in theprotection area. It is beyond the scope of this study to determine whether any specific potentialsource is actually releasing a contaminant, or to what extent any potential source(s) may becontributing to the overall pollutant load.

The transportation network is a potential source of contamination through vehicular accidentsthat release hazardous materials. Approximately 10.8 miles of roads and 0.6 miles of rail linestraverse the protection area, creating a total of 10 road and one rail crossings of Ten Mile Creekor its tributaries. Approximately 0.54 miles of roads and 0.12 miles of rail are within 100 feet ofa stream. Ten of the road crossings and one of the rail crossings occur within the corridormanagement zone.

6.0 SUSCEPTIBILITY ANALYSIS

For the purposes of source water assessments, all surface waters are considered to besusceptible to contamination. By their nature surface waters are accessible and can be readilycontaminated by chemicals and pathogens, with relatively short travel times from source to theintake. Based on the information compiled for this assessment, the Village of Metamoradrinking water source protection area is susceptible to agricultural runoff, transportation relatedspills, and discharges from failing or improperly maintained home septic systems.

It is important to note that this assessment is based on available data, and therefore may notreflect current conditions in all cases. Water quality, land uses and other activities that arepotential sources of contamination may change with time. While the source water for the Villageof Metamora Public Water System is considered susceptible to contamination, historically, the

Village of Metamora Public Water System has effectively treated this source water to meetdrinking water quality standards.

7.0 PROTECTIVE STRATEGIES

Source water protection efforts for the Village of Metamora should focus on controllingagricultural runoff and runoff from cattle grazing pastures, with particular attention to sources ofpesticides, nitrates, phosphorus, and microorganisms such as fecal coliform bacteria. This canbe accomplished via educational efforts. County Extension agents are an excellent resource forassisting the agricultural community with controlling agricultural runoff, and staff from local andCounty health offices can instruct homeowners in proper maintenance of their septic systems.

Other source water protection efforts may include:

Education and Outreach: Informing people who live, work, or own property within theprotection area about the benefits of drinking water protection is very important. Although somecommunities develop their own educational outreach resources, assistance is available at nocost from various agencies. For example, staff from Ohio EPA’s Office of Pollution Preventioncan visit businesses (free of charge) and provide recommendations on how they can modifytheir processes, materials and practices to generate less pollution in a cost-effective andtechnically feasible manner. An effort should be made to educate homeowners and businessesof the potential threat their activities can pose to the water supply. Education could also focuson increasing public awareness of illegal dumping and drinking water protection.

Coordination with Existing Activities: Many local groups are engaged in programs thatcomplement a public water system’s drinking water source protection efforts. Working withgroups such as the Natural Resources Conservation Service, the Soil and Water ConservationDistrict, the Ohio Farm Bureau, or a local watershed planning organization ensures coordinationof their respective programs.

Agricultural Activities: Provide education to local farmers on the use of best managementpractices to reduce agricultural and animal feedlot runoff, use of proper manure handlingfacilities, proper handling and road safety with agricultural chemicals, and other methods tocontrol or reduce impacts to surface waters.

Transportation Routes: There is a potential for spills along roads within the protection area.The Village of Metamora may want to consider contacting the local fire department and localemergency planning agency about the location of the drinking water source protection area, sothat strategies can be developed to prevent spilled materials from impacting Ten Mile Creek.

Emergency Response Planning: The Village of Metamora should prepare a plan that includesearly warning of spills and coordination of response and remediation activities for spills that mayenter Ten Mile Creek. This plan should include emergency response actions for Ten MileCreek, such as the placement of absorbent booms to control oil spills, or the ability tomechanically add oxygen to oxidize chemicals with a high oxygen demand. Different responseplans could be developed for different types of contamination. The emergency response planmay also contain strategies for dealing with unexpected levels of runoff containing chemicalssuch as fertilizers and pesticides from adjacent land uses. Though it may be less catastrophicthan a major spill, this kind of contamination is more prevalent and is harder to detect andcontain.

Page 9: Drinking Water Source Assessment for the Village of Metamora · Drinking Water Source Assessment for the Village of Metamora SUMMARY Source Water Assessment and Protection. The following

Water Quality Monitoring: Monitoring does not directly prevent contamination, but theprotection plan will be more effective if the Village of Metamora conducts periodic monitoring ofraw water quality and quantity from Ten Mile Creek. For example, monitoring data can be usedto (1) determine optimal conditions or seasons for pumping water to the reservoirs; (2) estimatetime-of-travel for a chemical to reach the water treatment intake from various locations in TenMile Creek; (3) track water quality trends; and (4) evaluate the effectiveness of selectedprotective strategies. Sampling locations and schedules could be modified on an emergencybasis to monitor spills or the runoff of contaminants that may enter the reservoirs.

Zoning Ordinances: A water protection zoning ordinance is a regulatory control that typicallyplaces some restrictions or standards on activities conducted within a specified zone (such asthe corridor management zone and/or the emergency management zone). Such ordinancesenable the municipality to require people who live or work in this area to avoid contaminating thesource of the municipality’s drinking water. Ordinances can help ensure best managementpractices are being employed at local businesses and can help reduce the volume ofcontaminants stored within the protection area. The Village of Metamora may want to considerworking with Fulton County and the townships in the protection area to develop zoning overlaysthat require specific standards for chemical storage, handling of waste materials, and othersource control strategies. Several communities in Ohio have enacted very successful drinkingwater source protection ordinances. Copies can be obtained by contacting Craig Smith at (614)644-2752.

Regulatory Compliance: Where possible, the Village of Metamora can monitor thecompliance of potential contaminant sources with existing regulations through inspectionsand/or contact with regulatory agencies. If routine inspections are a regulatory requirement,they provide an excellent opportunity to educate an important segment of the community aboutthe importance of drinking water source protection. Inspections also provide an opportunity toencourage improved materials handling procedures, hazardous materials training, waste anddisposal assessments, facility spill/contingency planning, and pollution prevention initiatives.

Ohio EPA encourages the Village of Metamora to incorporate the types of protective strategieslisted above into a written drinking water source protection plan. It is also highly recommendedthat the Village form a “Protection Team” to develop the plan. Two guidance documents areavailable from Ohio EPA to assist with development of a Drinking Water Source Protection Plan. “A Guide to Developing Local Watershed Action Plans in Ohio” is available on the internet atwww.epa.state.oh.us/dsw/hps/wsguide.pdf and “Developing Local Drinking Water SourceProtection Plans” in Ohio is available at www.epa.state.oh.us/ddagw/pdu/ swap_psdoc.pdf.
