2019 Water Quality Report for  Charter Township of Genesee

This report provides a snapshot of the drinking water quality for Charter Township of Genesee for the calendar year 2019. Genesee County Drain Commissioner-Division of Water and Waste Services (GCDC-WWS) Water Treatment Plant are committed to meeting the state and federal water quality standards including the Lead and Copper Rule.  With the Great Lakes as our water source and proven treatment technologies,  GCDC-WWS Treatment Plant consistently delivers safe drinking water to our community.  Included are details about where our water comes from, what it contains, and how it compares to Environmental Protection Agency (EPA) and state standards.

About our system:

Your source water comes from Lake Huron. The watershed includes numerous short, seasonal streams that drain to Lake Huron. GCDC-WWS voluntarily developed and received approval in 2017 for a source water protection program (SWIPP) for the Lake Huron Water Treatment Plant and GCDC-WWS Treatment Plant intake.  The program includes seven elements that include the following: roles and duties of government units and water supply agencies, delineation of a source water protection area, identification of potential of source water protection area, management approaches for protection, contingency plans, siting of new sources and public participation and education.  If you would like to know more information about the Source Water Assessment or SWIPP, please contact the Public Works at (810) 640-2000.

Special information available:

 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 systems 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 microbial contaminants are available from the Safe Drinking Water Hotline 800-426-4791.

Health and safety information:

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 EPA’s Safe Drinking Water Hotline (800-426-4791).

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 result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining or farming.
  • Pesticides and herbicides, which may come from a variety of sources such as agriculture and residential uses.
  • Radioactive contaminants, which are naturally occurring or be the result of oil and gas production and mining activities.
  • 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.

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

Unregulated Contaminants

Unregulated contaminants are those for which EPA has not established drinking water standards. The purpose of

Unregulated monitoring is to assist EPA in determining the occurrence of unregulated contaminants in drinking water and

Whether future regulation is warranted. Before EPA regulates a contaminant, it considers adverse health effects, the

Occurrence of the contaminant in drinking water, and whether the regulation would reduce health risk. GCDC-WWS

Began monitoring for Unregulated contaminants in 2013 and willcontinue additional sampling in 2019 and 2020. The Charter Township of Genesee began Monitoring for Unregulated Contaminates in 2018 and continued sampling into 2019. The following tables list the Unregulated substances detected during the 2019 calendar year.

Information about lead:

If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. The water that the GCDC-

WWS Water Treatment plant delivers to our community does not contain lead. Lead in drinking water is primarily from materials and components

associated with service lines and home plumbing. The Charter Township of Genesee 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 want 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 (800-426-4791) or at http;//www.epa.gov/safewater/lead.

                                     

 

 

 

 

 

 

How do I read this Chart?

Our water is tested to assure that it is safe and healthy. These Tables are based on tests conducted by Genesee Township within the last five (5) calendar years. We conduct many tests throughout the year, however , only tests that show the presence of a contaminant are shown here. The table on this page is a key to the terms used in the table. Sources of Contaminants show where this substance usually originates.

 

  Key to Detected Contaminants Table

 

AL

 

Action Level

The concentration of a contaminant, which, if exceeded, triggers treatment

Or other requirements which a water system must follow.

 

HAA5

 

Halo Acetic Acids

HAA5 is the total of bromoacetic, chloroacetic, dibromo acetic, dichloroacetic,

and trichloroacetic acids. Compliance is based on the total.

 

 

LRAA

 

Locational Running Annual Average

The average of  analytical results for samples at a particular monitoring location during
