The City of Columbiana has prepared the following report to provide information to you, the consumer, on the quality of our drinking water. Included within this report is general health information, water quality test results, how to participate in decisions concerning your drinking water and water system contacts.


The City of Columbiana’s original water treatment plant (WTP) and raw water field were constructed in 1934. The WTP and well field underwent major modifications in 1954 and 1977, as well as several other modifications over the years, to accommodate increased system demands and to improve finished water quality. As of the last improvements, the existing facilities had a peak treatment capacity of 1.0 mgd and included nine raw water wells. The WTP and wells, along with the finished water distribution system, served the City’s service area of approximately 6.5 square miles, including approximately 6,400 residents and businesses.

In 2006, the City recognized the existing WTP was well beyond its useful life and could not be effectively modified or expanded to serve projected increases to system demands, nor meet current standards and regulations, which was supported by OEPA reviews and several engineering studies. Based on these studies, an entirely new WTP was authorized by the City to be designed and constructed, and funding sources were subsequently sought to support this endeavor.

Over a two-year period beginning in 2016, the all new WTP, with peak capacity of 2.25 mgd, was constructed just north of the existing WTP site. Additionally, two new raw water wells and approximately 19,100 lineal feet of raw water main improvements were constructed at various locations within the City’s system, and the existing WTP was demolished. The overall cost for the improvements was $20,493,000. The United States Department of Agriculture-Rural Development (USDA-RD) agency provided funding in the amount of $8,090,000 (Grant) and $11,224,000 (Loan), with the balance provided by Ohio Public Works (OPWC) and other City direct contributions.

The City of Columbiana Water Department has prepared the following report to provide information to you, the consumer, on the quality of our drinking water. Included within this report is general health information, water quality test results, how to participate in decisions concerning your drinking water and water system contacts.

What’s the source of your drinking water?

The City of Columbiana receives its drinking water from 9 wells in the aquifer assigned to the Allegheny Formation, Pennsylvania Age. A source water assessment recently indicated a high susceptibility to contamination. This rating does not imply that the well fields will become contaminated. This only means that the existing/know aquifers could become impacted if the potential contaminant sources are not properly managed. The Drinking Water Source Assessment for Columbiana prepared by the Ohio Environmental Protection Agency is available at: http//wwwapp.epa.ohio.gov/gis/swpa/OH1500312.pdf. The City of Columbiana has a current, 2018, unconditioned license to operate as Public Water System ID OH1500312.

What are sources of contamination to drinking water?

The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity.

Contaminants that may be present in source water include: (A) Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations and wildlife; (B) Inorganic contaminants, such as salts and metals, which can be naturally occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming; (C) Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm water runoff, and residential uses; (D) Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban Strom water runoff, and septic systems; (E) Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining activities.

In order to ensure that tap water is safe to drink, USEPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. FDA regulations establish limits for contaminants in bottled water which must provide the same protection for public health.

Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Federal Environmental Protection Agency’s Safe Drinking Water Hotline (1-800-426-4791).

Who needs to take special precautions?

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons, such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infection. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791).

About your drinking water.

The EPA establishes a regular monitoring schedule for each public water system. The City of Columbiana is regulated to routinely monitor for the following contaminants: Total Coliform Bacteria, E-coli Bacteria, Total Trihalomethanes (TTHM’s), Haloacetic Acids (HAA5), Fluoride, Nitrates, Nitrites, Radiological, Inorganic Chemicals, Synthetic Organic Chemicals (SOC’s), Volatile Organic Chemicals (VOC’s), Lead & Copper , Mercury, Radon and Total Chlorine. Samples were collected for a total of 46 different contaminants most of which were not detected in the Columbiana water supply. The Ohio EPA requires us to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently. Other testing includes 88 coliform bacteria tests and over 2000 water quality tests conducted at our water treatment facility during this year.

Listed below is information on those contaminants that were found in the City of Columbiana drinking water.

Lead Educational Information

If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. The City of Columbiana is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline at 800-426-4791or at http://www.epa.gov/safewater/lead.

Infants and young children are typically more vulnerable to lead in drinking water than the general population. It is possible that lead levels at your home may be higher than at other homes in the community as a result of materials used in your home’s plumbing. If you are concerned about elevated lead levels in your home’s water, you may wish to have your water tested and flush your tap for 30 seconds to 2 minutes before using tap water. Additional information is available from the Safe Drinking Water Hotline (1-800-426-4791).

How do I participate in decisions concerning my drinking water?
Public participation and comment are encouraged at regular meetings of the city council. Meeting times and dates can be obtained from the City Manager’s office. For more information on your drinking water contact Lance Willard.

Storage

Columbiana presently has two storage tanks. Capacities are 1 million and 500,000 gallons

Treatment Information

Columbiana water supply utilizes conventional lime softening, aeration, coagulation, sedimentation, stabilization, chlorination and fluoridation to produce the quality water Columbiana has enjoyed for over 80 years.

Backflow and Cross Connection Program

An active Backflow and Cross Connection Program further protects your water. This program serves to help protect the consumer against the entrance of any potential contaminant from entering the distribution system. Backflow Prevention Devices are required throughout the distribution system. The devices are tested annually by State Certified Backflow Testers.

Bacterial Protection

As a disinfectant, the OEPA requires that a minimum chlorine residual of .2mg/l free chlorine be maintained in all parts of the distribution system. To insure our compliance with this requirement, we collect daily samples from over 100 sampling points around the city. At no time in 2018 was there any indication of water quality problems affecting the drinking water. Also we conducted 88 bacterial tests on the water from the list of sampling points. All tests indicated the water was safe.

Boil Advisory

If a boil advisory is issued, this does not mean the water is unsafe to drink. It means, according to EPA guidelines, the designated area in the distribution system experienced conditions that may produce a situation for contamination. Because of this, it is advisable to boil the water prior to drinking it. During each advisory we collect samples for lab analysis to check for contamination. Once the results are received, if there is no contamination, the boil advisory is lifted.

Distribution Data

There are 1215 valves, 458 fire hydrants, 2583 service connections, and 213 backflow devices.

Definitions of some terms contained within this report.

• Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.

• Maximum Contaminant level (MCL): The highest level of contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.

• Maximum Residual Disinfectant Level (MRDL): The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.

• Maximum Residual Disinfectant Level Goal (MRDLG): The level of drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.

• Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.

• Parts per Million (ppm) or Milligrams per Liter (mg/L) are units of measure for concentration of a contaminant. A part per million corresponds to one second in a little over 11.5 days.

• Parts per Billion (ppb) or Micrograms per Liter (μg/L) are units of measure for concentration of a contaminant. A part per billion corresponds to one second in 31.7 years.

• The “<” symbol: A symbol which means less than. A result of <5 means that the lowest level that
could be detected was 5 and the contaminant in that sample was not detected.

• Picocuries per liter (pCi/L): A common measure of radioactivity.
