2018 ANNUAL DRINKING WATER QUALITY REPORT

IRA TOWNSHIP WATER DEPARTMENT

2018 ANNUAL DRINKING WATER QUALITY REPORT

We are pleased to present to you this year’s Annual Water Quality Report. This report is designed to inform you about the water quality and services we deliver to you every day. Our constant goal is to provide you with a safe and dependable supply of drinking water. We want you to understand the efforts we make to continually improve the water treatment process and protect our water resources. We are committed to ensuring the quality of your water. 

Our water source is Anchor Bay, Lake St. Clair, this is surface water fed by the St. Clair River. We are pleased to report that our drinking water is safe and meets Federal and State requirements. The State preformed an assessment of our source water in 2003 to determine the susceptibility or the potential for contamination. The source water report has been completed and Ira Township source water rating is highly susceptible. If you have any questions about this report or concerning your water utility, please contact Ira Township Water Department at 586-725-7231. Office hours are between 7:00 a.m. and 5:00 p.m. Monday through Friday. The water plant is located at 7069 Meldrum Rd., Fair Haven Michigan. Regularly scheduled Township Board meetings are held the first Monday of every month at 7:00 p.m. in the Township hall located at 7085 Meldrum Rd.

Ira Township Water department routinely monitors for contaminants in your drinking water according to Federal and State laws. Ira Township has conducted testing for more than 230 different possible drinking water contaminants. The water department also tests for the presence of coliform bacteria and E.coli in the plant tap and in the distribution system. This table shows the results of our monitoring for the period of January 1st to December 31, 2018. Some testing is done less often than once a year, as will be noted in the chart below. Drinking water, including bottled drinking water, may reasonably be expected to contain at least small amounts of some contaminants. It is important to remember that the presence of these contaminants does not necessarily pose a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA's Safe drinking Water Hotline (800-426-4791). The Ira Township Water Department does not monitor any bottled drinking water sold or used in Ira Township.

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:

Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations and wildlife.

Inorganic contaminants such as salts and metals, which can be naturally-occurring or results from urban storm water runoff, industrial or domestic discharges, oil and gas production, mining, or farming.

Organic chemical contaminants, including synthetic and volatile organics, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff and septic systems. Pesticides and Herbicides, which may come from a variety of sources such as agriculture, urban storm water run-off, and residential uses.

Radioactive, 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, EPA 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. 

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 infections. 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 microbiological contaminants are available from the Safe Drinking Water Hotline (800-426-4791).

Thank you for allowing us to continue providing your family with clean, quality water this year. We will make every effort to provide a safe, dependable water supply to our customers. If you have any questions about this report or your water supply, please call the Ira Water Department 586-725-7231 or email us at waterplant@iratownship.org

In the following tables you will find many terms and abbreviations you might not be familiar with. To help you better understand these terms, we’ve provided the following definitions:


Parts per million (ppm) or Milligrams per liter (mg/l) – one part per million corresponds to one minute in two years or a single penny in $10,000.

Parts per billion (ppb) or Micrograms per liter – one part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000.

Nephelometric Turbidity Unit (NTU) – nephelometric turbidity unit is a measure of the clarity of water. Turbidity in excess of 5 NTU is just barely noticeable to the average person.

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

Maximum Contaminant Level – The “Maximum Allowed” (MCL) is the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.

Maximum Contaminant Level Goal – The “Goal” (MCLG) is 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 Residual Disinfectant Level – or MRDL, means 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 - or MRDLG, means the level of a drinking water disinfectant below which there is no known or expected risk to health. MRLDGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.

Treatment Technique – A required process intended to reduce the level of a contaminant in drinking water.


Note: Some tests are not preformed every year. ”The State allows us to monitor for certain contaminants less than once a year because the concentrations of these contaminants are not expected to vary significantly from year to year. All of the data is representative of the water quality, but some are more than one year old” Results from the most recent test dating back no further than 5 years are reported in the tables below.

*The 90th percentile value means 90 percent of the homes tested have lead and copper levels below the given 90th percentile value. If the 90th percentile value is above the AL additional requirements must be met. Infants and children who drink water containing lead in excess of the AL could experience delays in their physical or mental development. Children could show slight deficits in attention span and learning abilities. Adults who drink this water over many years could develop kidney problems or high blood pressure.


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. There are no known lead service lines in Ira Township. Ira Township Water Department 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 1-800-426-4791 or at. http://water.epa.gov/drink/info/lead

Regulated Contaminant Treatment Technique - Running annual average - Monthly Ratio Range - Violation Yes/No Typical Source of Contaminant
Total Organic Carbon (ppm) The Total Organic Carbon (TOC) removal ratio is calculated as the ratio between the actual TOC removal and the TOC removal requirements. The TOC was measured each month and because the level was low, there is no requirement for TOC removal. Erosion of natural deposits

2018 Special Monitoring

Contaminant MCLG MCL Level Detected Source of Contamination
Sodium (ppm) n/a n/a 5.5 Erosion of natural deposits

Unregulated contaminants are those for which EPA has not established drinking water standards. Monitoring helps EPA to determine where certain contaminants occur and whether it needs to regulate those contaminants. The Township took a sample for PFAS on October 25th and the results came back as a non-detect.

We are required to monitor your drinking water for specific contaminants on a regular basis. Results of regular monitoring are an indicator of whether or not our drinking water meets health standards. During January 1, 2018, to September 30, 2018 we did not complete all monitoring for partial chemistry. Therefore, we cannot be sure of the quality of your drinking water during that time. This violation does not pose a threat to the quality of the supply’s water.


What should I do? There is nothing you need to do at this time. This is not an emergency. You do not need to boil water or use an alternative source of water at this time. Even though this is not any emergency, as our customers, you have a right to know what happened and what we are doing to correct the situation.

The table below lists the contaminants that were not properly tested for, how often we are supposed to sample for these contaminants, how may samples we are supposed to take, how many samples we took, when samples should have been taken, and the date we collected follow-up samples.

Contaminants Required sampling frequency Number of samples taken When samples should have been collected Date additional samples were collected
Partial Chemistry* 1 sample per year 0 January 1, 2018- September 30, 2018 November 8,2018

What happened? What is being done? The lab we use for these samples inadvertently failed to include these sample containers in with the other samples collected during the sampling period. Our staff is making every effort to assure this does not happen again.

Please share this information with all other people who drink this water, especially those who may not have received this notice directly. You can do this by posting this notice in a public place or distributing copies by hand or by mail. This notice is being sent by Ira Township.


*Partial Chemistry compounds are tested by collecting one sample and testing that sample for nitrate, possibly nitrite, fluoride, sodium and other parameters, depending on the laboratory used. Sampling for nitrite, fluoride, and sodium may be required less frequently than for nitrate, but all these compounds may be tested during a Partial Chemistry analysis.
