Drinking Water Source

Hecla Water’s primary water source is groundwater from the Ohio River Valley Aquifer System located along side State Route 7, just south east of Athalia, Ohio. The well field contains eight wells which pump over two million gallons of water each day. The treatment process includes sand filtering, fluoridation and chlorination. The softening process was eliminated due to the increase in demand. Hecla Water has a source protection plan which is being updated to include added security measures. The Homeland Security Act protects the details of the protection plan and additional security. If you have any questions about this report or concerning your water company, contact Tim Dalton at 533-0526. If you want to learn more about your water system, attend the regularly scheduled meetings, held each month on the fourth Thursday at 11:30 AM at the office on State Route 141.

Hecla Water also uses the City of Ironton as a secondary source of water. The city treats surface water from the Ohio River through pre-sedimentation, upflow clarification, filtration, and chlorination. The Ironton Water Treatment plant was constructed in 1993 and provides approximately 1.74 million gallons of drinking water a day. Customers in the Coryville and Porter Gap areas are fed from the Ironton interconnection. Although less than 1% of the daily supply, Ironton serves as a supplementary and emergency connection for Hecla Water.

Sources of Contamination

What are sources of contamination to drinking water? The sources of drinking water (both tap water and bottled) 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 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 storm 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).

Definitions for Test Results Tables

Less Than = < ] [More Than = >] [ N/A or NA = not applicable ] [ nonreg = non regulated by EPA] [TT = treatment technique] [NTU = nephelometric turbidity units]

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

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 residual disinfectant level allowed. Maximum Residual Disinfectant Level Goal (MRDLG): The level of residual disinfectant below which there is no known or expected risk to health.

All drinking water contains a small amount of some contaminants.

Turbidity

Turbidity is a measure of the cloudiness of water and is an indication of the effectiveness of our filtration system. The turbidity limit set by the EPA is {0.3 NTU) in 95% of the daily samples and shall not exceed 1 NTU at any time. As reported above, The purchased water from the city of Ironton’s highest recorded turbidity result for 2020 was 0.19 NTU and lowest monthly percentage of samples meeting the turbidity limits was 100%.

Lead In Drinking Water

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 Hecla Water Association 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 drinking water, testing methods, and steps you can take to minimize exposure is available from the safe drinking water Hotline at www.epa.gov/safewater/lead

Initial Distribution System Evaluation

Under the Stage 2 Disinfectants/Disinfection byproducts Rule (D/DBPR), our public water system was required by USEPA to conduct an evaluation of our distribution system. This is known as an Initial Distribution System Evaluation (IDSE), and is intended to identify locations in our distribution system with elevated disinfection byproduct concentrations. The locations selected for the IDSE may be used for compliance monitoring under Stage 2 DBPR, beginning in 2012. Disinfection byproducts are the result of providing continuous disinfection of your drinking water and form when disinfectants combine with organic matter naturally occurring in the source water. Disinfection byproducts are grouped into two categories. Total Trihalomethanes (TTHM) and Haloacetic Acids (HAA5). USEPA sets standards for controlling the levels of disinfectants and disinfectant byproducts in drinking water, including both TTHMs and HAA5s.

Unregulated Contaminants

Unregulated contaminants monitoring helps the EPA to determine where certain contaminants occur and whether the EPA needs to regulate those contaminants.

Susceptibility Analysis

The aquifer that supplies drinking water to the Hecla Water Association wells is moderately susceptibility to contamination. This determination was made because of the following reasons:

-The water table of the sand and gravel aquifer begins approximately 40 feet below the ground surface.
-There is approximately 15-25 feet of sandy clay overlying the sand and gravel. This may slow the migration of contaminants into the aquifer.
-Potential significant contaminant sources exist within the protection area.

Water quality data were evaluated using the drinking water compliance database at Ohio EPA. The available data do not indicate that contamination has impacted the aquifer at Hecla Water Association’s wellfield. Because sampling requirements are for treated water, the lack of water quality impacts does not necessarily indicate a lack of contamination. This determination is limited by the sampling that is performed for the water system. Eight (8) potential sources of contamination have been identified by Hecla Water Association including SR 7, the Ohio River, home septic systems, an auto body shop, commercial facilities with fuel/fuel oil tanks, and a salvage yard. Because of these potential sources of contamination that exist within the wellhead/source water protection area and the moderate sensitivity of the aquifer, the Hecla Water Association’s wellfield is considered to be moderately susceptible to contamination. In summary, there is a moderate likelihood for contamination of the Hecla Water Association’s source water. Implementing appropriate protection strategies for the potential contaminant sources will help reduce the likelihood of contamination affecting the aquifer.

Consumer Confidence Report Deficiencies

The Ohio EPA notified the Hecla Water Association of four deficiencies in the 2019 Consumer Confidence Report. These deficiencies have been addressed, corrected, and added to the 2020 Consumer Confidence report. The deficiencies included mandatory language concerning sources of water, definitions of MCLG and MRDLG, removal of old violations, and correct units of measurement for copper (ppm).

What Should I do?

You do not need to take any actions in response to this notice. These deficiencies have been addressed, corrected, and added to the 2020 Consumer Confidence report. The deficiencies included mandatory language concerning sources of water, definitions of MCLG and MRDLG, removal of old violations, and correct units of measurement for copper (ppm).
