Annual Drinking Water Quality Report for 2000

The Villages of Carthage and West Carthage

61 High Street , West Carthage NY 13619

(Public Water Supply ID #2202334 and 2202349 )

Introduction

To comply with State and Federal regulations, we will be annually issuing a report describing the quality of your drinking water. The purpose of this report is to raise your understanding of drinking water and awareness of the need to protect our drinking water sources. This report provides an overview of last year’s water quality. Included are details about where your water comes from, what it contains, and how it compares to State standards. If you have any questions about this report or concerning your drinking water, please contact Ernie Prievo at (315) 493-2210 or Tim Turck at (315) 493-1718. We want you to be informed about your drinking water. If you want to learn more, please attend any of our regularly scheduled monthly Joint Water meetings held at the West Carthage Municipal Building at 5:00 p.m. on the second Wednesday of each month.

Where does our water come from?

In general, 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 can pick up substances resulting from the presence of animals or from human activities. Contaminants that may be present in source water include: microbial contaminants; inorganic contaminants; pesticides and herbicides; organic chemical contaminants; and radioactive contaminants. In order to ensure that tap water is safe to drink, the State and the EPA prescribe regulations which limit the amount of certain contaminants in water provided by public water systems. The State Health Department’s and the FDA’s regulations establish limits for contaminants in bottled water which must provide the same protection for public health.

Our water source is a clean and plentiful spring fed source known as the Indian River located in Belfort , New York. The Village’s own 1,500 acres of uninhabited forest land that surrounds the drinking water source. The water from this source flows into a man made reservoir approximately two miles downstream. Once the water enters the reservoir a process of settling occurs before it enters the screen house. In the screen house the water passes through a fine screen prior to entering the 15 miles of transmission line. The water travels through the transmission pipe via gravity to the Village’s Slow Sand Filtration Plant located on West Street Road. The filter plant is operated 365 days a year by employees from Carthage and West Carthage who are New York State Licensed Operators. The operators conduct water quality testing , routine plant maintenance , as well as record daily water consumption. It should be noted that the reservoir is drained and cleaned once a year and the screens in the screen house are cleaned weekly. During 2000, our system did not experience any restriction of our water source.

At the water filtration plant the water flows into three filter beds and passes through a sand aggregate prior to being treated. Once the water is filtered , it is disinfected with sodium hypo-chlorite ( chlorine ). Sodium hypo-chlorite kills bacteria that may be present in the water . The amount of sodium hypo-chlorite added to the water is continuously monitored at the plant to achieve the desired 1.0 mg/L concentration. The chlorine residual in the distribution system is measured at various locations at least four times each week.

Turbidity is a measure of the water’s clarity and both the raw and filtered water turbidity is continuously monitored at the plant. Turbidity measurements are also collected throughout the distribution system at least four times each week.

Before entering the distribution system hydrofluosilic acid and zinc orthophosphate are added to the water. Hydrofluosilic acid adds fluoride to the water at a concentration of 1.0 mg/L and is monitored at the filter plant. Fluoride has been shown to reduce tooth decay and dental cavities. The New York State Department of Health also analyzes the fluoride concentration once per month. Zinc orthophosphate works to make the water less corrosive, thus , reducing the solubility of lead and copper that may be present in the distribution plumbing. This is continuously monitored at the filter plant. The target zinc orthophosphate concentration is 1.0 mg/L.

Facts and Figures

 

Our water system serves approximately 7,000 individuals through an estimated 1,800 service connections. This number includes the entire population of the two Villages as well as a small number of customers in the Towns of Wilna, Champion and Denmark. The total amount of water treated at the filter plant in 2000 totaled 194,700,324 gallons. The daily average of water treated and pumped into the distribution system was 534,891 gallons. This was an increase of 1,545,908 gallons of water from last year. Our highest single day was May 25th , the day of the fire at the Carthage Bowling Alleys, when we pumped 752,000 gallons.

Carthage billed a daily average of 287,338 gallons while pumping 349,429 gallons. This represents a difference of 62,091 gallons of water per day not billed or 17.77 %. West Carthage billed a daily average of 169,117 gallons while pumping 185,462 gallons. This represents a difference of 16,345 gallons of water a day not billed or 8.81%. Some of this unaccounted for water loss was used to fight fires, clean streets, flush hydrants and other community provided services that require the use of water where metering or calculating this usage would be very difficult. The water rates for residents in the Village of Carthage are $1.70 per 100 cubic feet (748 gallons) , Town of Wilna residents pay $3.00 per 100 cubic feet , residents of the Village of West Carthage pay $2.40 per 100 cubic feet and the Towns of Champion and Denmark are charged $4.80 for 100 cubic feet of water used.

 

 

Are there contaminants in our drinking water?

As the State regulations require, we routinely test your drinking water for numerous contaminants. These contaminants include: total coliform, turbidity, inorganic compounds, nitrate, nitrite, lead and copper, volatile organic compounds, total trihalomethanes, and synthetic organic compounds. The table presented below depicts which compounds were detected in your drinking water. The State allows us to test for some contaminants less than once per year because the concentrations of these contaminants do not change frequently. Some of our data, though representative, are more than one year old.

Notes:

1 – Turbidity is a measure of the cloudiness of the water. We test it because it is a good indicator of the effectiveness of our filtration system. Our highest single turbidity measurement for the year occurred on 5/18/00. State regulations require that turbidity must always be below 5 NTU. The regulations require that 95% of the turbidity samples collected have measure less than or equal to 1.0 NTU. All of the measurements collected in 2000 were less than or equal to 1.0 NTU. Our daily average measurement for this year was 0.24 NTU.

2 – During 1999, six samples were collected from the West Carthage Distribution System and analyzed for lead and copper. The number presented represents the average of the two highest levels detected.

3 – The level presented represents the range of the six samples collected from the West Carthage Distribution System in 1999. Neither lead nor copper was detected above the action level at any of the sites tested.

4 – The level presented represents the 90th percentile of the 14 sites tested for lead and copper in the Carthage Distribution System. A percentile is a value on a scale of 100 that indicates the percent of a distribution that is equal to or below it. The 90th percentile is equal to or greater than 90% of the copper values detected at your water system. In this case, 14 samples were collected at your water system and the 90th percentile value was the second highest value. The action levels for lead and copper were not exceeded in any of the samples collected.

5 - Water containing more than 20 mg/L of sodium should not be used for drinking by people on very restricted sodium diets. Water containing more than 270 mg/L of sodium should not be used for drinking by people on moderately restricted sodium diets.

Definitions:

Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible.

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.

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

Treatment Technique(TT): A required process intended to reduce the level of a contaminant in drinking water.

Non - Detects (ND): Laboratory analysis indicates that the constituent is not present.

Nephelometric Turbidity Unit (NTU): a measure of the clarity of water. Turbidity in excess of 5 NTU is just noticeable to the average person.

Milligrams per liter (mg/L): Corresponds to one part of liquid in one million parts of liquid (parts per million -ppm).

Micrgrams per liter (ug/L): Corresponds to one part of liquid in one billion parts of liquid (parts per billion - ppb).

What does this information mean?

As you can see by the table, our system had no violations. We have learned through our testing that some contaminants have been detected; however, these contaminants were detected below the level allowed by the State.

Is our water system meeting other rules that govern operations?

Yes, During 2000, our system was in compliance with all applicable State drinking water requirements.

Do I Need to Take Special Precautions?

Although our drinking water met or exceeded state and federal regulations, some people may be more vulnerable to disease causing microorganisms or pathogens 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 infections. These people should seek advice from their health care provider about their drinking water. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium, Giardia and other microbial pathogens are available from the Safe Drinking Water Hotline (800-426-4791).

Why Save Water and How to Avoid Wasting It?

Although our system has an adequate amount of water to meet present and future demands, there are a number of reasons why it is important to conserve water:

You can play a role in conserving water by becoming conscious of the amount of water your household is using, and by looking for ways to use less whenever you can. It is not hard to conserve water. Conservation tips include:

System Improvements

Reservoir ImprovementsVillage employees from both Carthage and West Carthage spent six weeks this summer rebuilding 310 feet of containment wall on the south and north side of the third pond at the Belfort Reservoir. This was the second phase of the project. Phase one consisted of rebuilding 300 feet of containment wall on the south side of the first and second ponds. This project was engineered and estimated to cost $140,00.00 using a licensed contractor. We completed phase one at a cost of $15,000.00 and this year we completed phase two at a cost of $23,000.00 for a total expense to date of $38,000.00. To date we have saved over 40% of the original cost estimate. We also installed new intake piping and raised them to draw water from 18 inches above the reservoir floor , greatly reducing the amount of sedimentation that was once entering the screen house. This improvement has reduced our raw water Turbidity levels to 0.19NTU and will increase the run times from our filter beds.

Water System Maintenance

Along with servicing the 26 Air/Vacuum valves on the transmission line from Belfort, employees from both village’s spent one week cleaning the reservoir as part of their annual program. Employees also inspect the two miles of springs that supply the reservoir periodically to check for signs of disturbance that may pose a potential risk to the quality of our water system. This year the 100 foot water storage tanks in Carthage and the 20 foot storage tank in West Carthage were inspected by Liquid Engineering . This inspection consisted of a crew of three men who actually dove into the tanks with underwater camera equipment and inspected the inside of the tanks for excess corrosion. Their inspection was recorded on VHS tape and a copy of the report was sent to the New York State Department of Health for their review. This inspection indicated that all three tanks were in excellent structural condition for their age , however , their recommendation included having all three tanks re-coated in the near future.

The filter plant is operated by licensed operators everyday of the year including Holidays. These operators are always attending training seminars and required class room studies to learn ways to improve the quality of water they deliver to you, the consumer. Routine maintenance at the filter plant and Booster Pump Station is conducted by these same employees. The water dept. employees from both villages spend a great deal of time conducting leak detection throughout the distribution system as well as replacing old fire hydrants, valves and water lines. A summary of our work can be obtained from the Clerk’s Office of each Village.

Closing

The business of providing the public with water of excellent quality is a full time task. The next time you pour a glass of water , wash a load of clothes , or just water your garden take a minute and consider what it takes to receive this service. Every home on every street has a water line which is connected to a water main which delivers water from the filter plant that receives water through a 12 inch main that is 15 miles long that receives its water from a spring fed source that is protected by 1500 acres of uninhabited forest. Every part of this system needs constant attention to keep it operating. Systems of this magnitude do not operate without problems and these problems don’t always occur during normal working hours. Many times the water dept. employees are working late at night in less than favorable conditions repairing a problem so that the service to you , the customer , is maintained. All to often we take for granted the little things in life. Our abundant water source is the life blood of our community and needs to be protected and appreciated .

Thank you for allowing us to continue to provide your family with quality drinking water this year. We ask that all our customers help us protect our water sources. Should you have any questions about the information in this report or want to learn more about the service we provide please feel free to contact Ernie Prievo at ( 315) 493-2210 , Tim Turck at (315) 493-1718, or the New York State Department of Health at (315) 785-2277.
