Bloomfield Township Water Quality

FAQs About Lead and Copper in Water

Per the requirements of the Lead & Copper Rule, Bloomfield Township samples the water at seven selected high-risk homes and sends it out for testing at a state certified lab. If more than 1 sample shows lead levels at above 15 micrograms per liter, we will notify all of our customers and provide instructions on what to do to limit lead exposure as required by MDEQ. Since you cannot see, taste, or smell lead dissolved in water, testing is the only sure way of telling whether there are harmful quantities of lead in your drinking water. Bloomfield Township does not offer testing of water, however if you would like to have your water tested, you can find more information at the link above for MDEQ’s Drinking Water Laboratory.

What You Can Do to Help Protect Our Water Resources

Household hazardous waste: Never dump items such as used motor oil, fuel products, cleaners, paints, and/or pesticides on the ground or down the drain. They can contaminate groundwater and surface water. Instead, bring these types of items to the Bloomfield Township household hazardous waste collection events held the first Saturday in May and October.

Prevent Cross Connections

A cross connection is a direct or potential arrangement of drinking water piping that is or can be connected to a questionable water source. An example is the common garden hose attached to a outside spigot with the end of the hose submerged in a bucket of soapy water. Cross connections may allow backsiphonage or backpressure backflow to occur. Backsiphonage is a reversal of normal flow in a system caused by negative pressure piping. This can occur during repairs or breaks in water mains or at an increase in demand due to fire fighting. To prevent the most common form of cross connection, the ordinary garden hose, check to make sure your hose is equipped with a Hose Bibb Vacuum Breaker. These are typically about $5-$10 from your hardware store. Other backflow prevention devices, such as pressure vacuum breakers commonly found on irrigation systems should be checked and tested regularly by a licensed plumber that is certified with the State.

Septic systems: If you have a septic system, have it checked every two to three years to ensure it is working properly.

Irrigation: Water every other day. Adjust sprinkling systems so that you will be watering between the hours of 11:00 PM and 5:00 AM. Remember to turn off your system when it's raining.

Pet waste: Because pet waste can be high in bacteria and nutrients, it should be disposed of in a toilet or trashcan.

Lake Huron Water Treatment Plant - 2016 Regulated Detected Contaminants*

*Information and Data supplied by GLWA Water Quality Division

2016 Regulated Detected Contaminants

Significant portions of this report contain mandatory language as required by the 1996 Federal Safe Drinking Water Act amendments. These sections are shown in italics.

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 Environmental Protection Agency’s Safe Drinking Water Hotline at (800-426-4791).

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 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, urban storm water runoff, and residential uses.
  • 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.
  • 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, EPA prescribes regulations, which limit the amount of certain contaminants in water provided by public water systems. The Food and Drug Administration (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 is 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 microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791).

Information about Lead in Drinking Water

Safe drinking water is a shared responsibility. The water that GLWA delivers to your community does not contain lead. However, lead can leach into drinking water through your home’s plumbing fixtures, and in some cases, customer service lines. Corrosion control reduces the risk of lead and copper from leaching into your water. Orthophosphates are added during the treatment process as a corrosion control method to create a protective coating in service pipes throughout the system, including in your home or business. Bloomfield Township performs required lead and copper sampling and testing in our community. Water consumers also have a responsibility to maintain the plumbing in their homes and businesses, and can take steps to limit their exposure to lead.

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. Bloomfield Township 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 or at http://www.epa.gov/safewater/lead.

Where Does My Water Come From?

Bloomfield Township purchases water from the Southeastern Oakland County Water Authority (SOCWA) and SOCWA’s source water comes from the lower Lake Huron watershed. The watershed includes numerous short, seasonal streams that drain to Lake Huron. The Michigan Department of Environmental Quality in partnership the Detroit Water and Sewerage Department and several other governmental agencies performed a source water assessment in 2004 to determine the susceptibility or relative potential of contamination. The susceptibility rating is on a seven-tiered scale ranging from “very low” to “very high” based primarily on geologic sensitivity, water chemistry, and contamination sources. The Lake Huron source water intake is categorized as having a moderately low susceptibility to potential contaminant sources. The Lake Huron water treatment plant has historically provided satisfactory treatment of this source water to meet drinking water standards.

GLWA voluntarily developed and received approval in 2016 for a source water protection program (SWIPP) for the Lake Huron Water 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 the SWIPP please, contact the Bloomfield Township DPW at 248-594-2800.

Southeastern Oakland County Water AuthorityWhy Do We Purchase Water from SOCWA?

In July of 2011, the Township began purchasing water from Southeast Oakland County Water Authority (SOCWA) instead of directly from Detroit Water and Sewerage Department (DWSD). The large water storage capacities provided by SOCWA allow them to avoid more costly peak demand charges and provide a more stable rate. Since 2011, we have been able to avoid millions of dollars in costs for purchasing water as opposed to staying directly with DWSD. For more information about SOCWA, visit their website at www.socwa.org

SOCWA Water FAQ’s

  • What is the hardness of my water?
    Depending on the manufacturer of your appliance, you need to know the ppm (parts per million) of your water or the "grains of hardness". SOCWA water runs consistently at 100 ppm or 6 grains of hardness.
  • How much sodium (Na) does my water contain?
    SOCWA water contains about 4 mg/L (milligrams per liter) of sodium year round.
  • How do I know that the water I am using is safe to drink?
    SOCWA samples 56 sites throughout the service area every week to test for possible contamination. So rest assured, your water is safe.
  • My drinking water looks cloudy when taken from the faucet. Should I be concerned?
    No. The cloudy water is caused by tiny air bubbles in the water similar to the gas bubbles in carbonated soft drinks. After a while, the bubbles rise to the top and are gone. This type of cloudiness occurs more often in the winter, when the drinking water is cold.
  • Is water with chlorine in it safe to drink?
    Yes. Many tests have shown that the amount of chlorine found in treated water is safe to drink, although some people object to the taste.
  • Should I buy bottled water?
    Remember that US bottled water is less regulated than municipal drinking water. You don't need to buy bottled water for health reasons if your drinking water meets all of the federal or state drinking water standards. (Bloomfield Township’s water meets those standards). If you want a drink with a different taste, you can buy bottled water, but it costs up to 1,000 times more than municipal drinking water.

Check for Leaks and Stop Money from Going Down the Drain!

Meter ReadingA leaky faucet or toilet can waste hundreds of gallons of water every day. One way to check for leaks is to check the low flow indicator on your water meter. Water meters are typically located in the basement, laundry room or utility closet. The low flow indicator is the red diamond or triangle-shaped indicator (shown in image to the right) equipped on most meters. Make sure all the water is turned off in and outside of the house, then if the low–flow indicator is moving or spinning at all, there is water flowing through the meter which would indicate a leak somewhere in the home.

Having a leak repaired will be less costly in the long run than the amount you will pay for wasted water. Please remember, Bloomfield Township cannot adjust your bill for water wasted through leaks!
