Get to Know Your Water Source

Your Health

Some people may be more vulnerable to contaminants in drinking water than others. People with weakened immune systems have a higher risk of infection, including but not limited to the following groups:

• People receiving chemotherapy

• Organ transplant recipients

• People with HIV/AIDS or other immune systems disorders

• Some elderly individuals

• Infants 

These groups should seek advice from their health care providers about drinking water. U.S. EPA and the Center for Disease Control also have guidelines to lessen your risk of infection by microbial contaminants.

Contaminants

Drinking water, including bottled water, may contain at least small amounts of some contaminants. The presence of contaminants does not necessarily mean that water poses a health risk.

You can get more information about contaminants and potential health effects by calling the U.S. EPA’s Safe Drinking Water hotline (800-426-4791) or visiting epa.gov/safewater.

Source Water Protections

In 2003, the State of Michigan performed an assessment on our source water. This assessment looked at Lake Michigan’s susceptibility or the relative potential of contamination. The susceptibility rating is given on a scale from “very-low” to “very-high,” with seven possible ratings. Ratings are based on geologic sensitivity, water chemistry and contamination sources. The State rated the Holland BPW’s water intake as “moderately sensitive.” It rated the water source itself as having a “moderately high” susceptibility to contamination.

The State identified 364 potential sources of contamination in the 175 square miles of watershed that could impact our water source. Their report further states, “Historically, the Holland Board of Public Works Water Treatment Plant has effectively treated this water source to meet drinking water standards. There have been no detections of synthetic or volatile organic contaminants in the system’s raw water.” You can get a copy of Holland BPW’s full Source Water Assessment by calling 616.355.1500.

To continue these efforts, Holland BPW has an award-winning Surface Water Intake Protection Plan (SWIPP) in place. The EPA and EGLE encourage this voluntary effort that outlines community-wide actions and efforts to protect drinking water sources. For more information about Holland BPW’s SWIPP, please call the Water Treatment Plant at 616.355.1589.

Sources of Drinking Water

Drinking water (both from the tap and bottled water) can come from rivers, lakes, streams, ponds, reservoirs, springs or wells. Holland BPW’s drinking water comes from Lake Michigan. 

As water travels across land or underground, it dissolves naturally-occurring minerals and sometimes radioactive material. Water can also pick up contaminants that come from animal or human activity.

Contaminants that may be present in source water include:

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

• Inorganic contaminants, such as salts and metals. Some of these occur naturally. Salts and metals can also come from urban storm water runoff, industrial or domestic wastewater, oil and gas production, mining or farming.

• Pesticides and herbicides. These may come from a variety of sources including agriculture and residential uses.

• Radioactive contaminants. These can be naturally-occurring or the result of oil and gas production and mining activities.

• Organic chemical contaminants. These include synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production. Organic chemical contaminants can also come from gas stations, urban storm water runoff and septic systems.

To ensure that tap water is safe to drink, the U.S. EPA limits the levels of certain contaminants in public water systems. Similarly, Federal Food and Drug Administration regulations limit contaminants in bottled water to protect public health.

Lead & Copper

Pipes can be made of a variety of materials such as iron or plastic. In the past, some may have been made from galvanized metals or lead. Holland BPW completed an inventory of water service lines in 2024. This inventory did not identify any service lines made completely out of lead pipe. This inventory was based on information provided in construction records and plumbing inspections required when service lines were installed or replaced and was verified through visual inspection of a statistically significant number of randomly selected service lines. The inventory is updated any time new records and inspections are obtained.

Most metals disintegrate as they corrode. However, corroding galvanized pipes pick up deposits that the water carries from other pipes in the system. Because these galvanized pipes were once connected to lead goosenecks, lead deposits may have built up inside the galvanized pipe.

For this reason, Holland BPW has a program in place to replace all remaining galvanized lines in the system by the end of 2038. This time frame aligns with State of Michigan regulations and Holland BPW’s asset management plan. This replacement program includes:

1. The public section of the galvanized service lines from the water main to the property line.
2. The private section between the property line and the home, which is usually the responsibility of the homeowner.

Any galvanized piping inside the home is still the responsibility of the homeowner to replace as desired.

Lead

Lead can cause serious health effects in people of all ages, especially pregnant people, infants (both formula-fed and breastfed), and young children. Lead in drinking water is primarily from materials and parts used in service lines and in home plumbing. Holland Board of Public Works is responsible for providing high quality drinking water and removing lead pipes but cannot control the variety of materials used in the plumbing in your home. Because lead levels may vary over time, lead exposure is possible even when your tap sampling results do not detect lead at one point in time.

You can help protect yourself and your family by identifying and removing lead materials within your home plumbing and taking steps to reduce your family’s risk. Using a filter, certified by an American National Standards Institute accredited certifier to reduce lead, is effective in reducing lead exposures. Follow the instructions provided with the filter to ensure the filter is used properly.

Use only cold water for drinking, cooking, and making baby formula. Boiling water does not remove lead from water. Before using tap water for drinking, cooking, or making baby formula, flush your pipes for several minutes. You can do this by running your tap, taking a shower, doing laundry or a load of dishes. If you have a lead service line or galvanized requiring replacement service line, you may need to flush your pipes for at least 5 minutes to flush water from both your home plumbing and the lead service line.

If you are concerned about lead in your water and wish to have your water tested, contact Holland Board of Public Works, Water and Wastewater Service Department, at

(616) 355 – 1643 for available resources. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available at https://www.epa.gov/safewater/lead.

Copper

Copper is an essential nutrient. However, drinking water with copper levels higher than the action level in a short amount of time could cause gastrointestinal distress. Some people who drink water with copper levels higher than the action level over many years could suffer liver or kidney damage. People with Wilson’s Disease or other conditions that limit the body’s ability to remove excess copper should talk to their health care provider.

PFAS

Per- and polyfluoroalkyl substances (PFAS), sometimes called PFCs, are a group of chemicals that are resistant to heat, water, and oil. The U.S. EPA has named PFAS as an emerging contaminant. For decades, PFAS have been used in industrial applications and consumer products and are still used today. Products with PFAS include carpeting, waterproof clothing, upholstery, food paper wrappings, fire-fighting foams, and metal plating. PFAS have also been found at low levels in both the environment and blood samples from the general U.S. population.

These chemicals are persistent, which means they do not break down in the environment. PFAS chemicals also bioaccumulate, meaning the amount of the chemical in a person’s body builds up over time in their blood and organs. 

Why was Holland BPW’s Source Water Tested for PFAS?

Holland BPW follows the EGLE standard compliance monitoring schedule for PFAS Maximum Contaminant Levels (MCLs). In 2020, EGLE developed MCLs for seven PFAS compounds in Michigan. Even before EGLE developed PFAS MCLs, Holland BPW participated in EGLE-coordinated voluntary sampling in 2019. With health and safety at the core of our values, we saw this initiative as a chance to learn about our source water.

How Can PFAS Affect People’s Health?

Although our understanding of these emerging contaminants constantly changes, higher levels of PFAS have the potential to cause negative health effects. These include increased cholesterol, changes in hormones and the immune system, decreased fertility, and increased risk of some cancers. Epidemiological and laboratory studies in animal models support these links to health effects in humans. 

If you are concerned about exposure to PFAS in your drinking water, please contact

• Michigan Department of Health and Human Services Toxicology hotline at 800-648-6942

• Center for Disease Control and Prevention/ATSDR at www.cdc.gov/cdc-info or 800-232-4636.

Scientists are still learning about the health effects of exposure to PFAS, including exposure to mixtures.

What Other Ways Could I Be Exposed to PFOA, PFOS and Other PFAS Compounds?

PFAS are used in many consumer products, including:

• Food packaging such as fast-food wrappers and microwave popcorn bags 

• Waterproof and stain-resistant fabrics such as outdoor clothing, upholstery, and carpeting

• Nonstick coatings on cookware

• Cleaning supplies including some soaps and shampoos.

Exposure to PFAS can come from house dust, indoor and outdoor air, food, and drinking water. More research is needed to understand how people can be exposed to PFAS.

Who Can I Call if I Have Questions about PFAS in my Drinking Water?

If any resident has additional questions regarding this issue, the State of Michigan Environmental Assistance Center can be contacted at 800-662-9278.

Unregulated Contaminants

The 1996 Safe Drinking Water Act (SDWA) amendments require that once every five years the EPA must issue a new list of no more than 30 unregulated contaminants to be monitored by public water systems.

The fourth Unregulated Contaminant Monitoring Rule (UCMR 4) was published in the Federal Register on December 20, 2016. UCMR 4 required monitoring for 30 chemical contaminants between 2018 and 2020 using analytical methods developed by EPA and consensus organizations. This monitoring provides a basis for future regulatory actions to protect public health.

Water Conservation

Lake Michigan is a precious resource. We share this great resource with plants, animals, fish, and each other. Just as we share in the benefits of this Great Lake, we share in the responsibility of protecting and conserving our water source.

Protecting Our Water Resources

The greatest increase that our water utility sees in demand is the result of lawn irrigation in the summer months. Grass lawns often have shallow roots and need greater amounts of water to keep them from going brown and dormant in the hot summer. One of the best ways to save water and money on your utility bill is to reduce your summer lawn sprinkling.

Holland BPW has worked to reap the benefits of converting traditional lawns to native landscapes at three of our main facilities: the Service Center, Holland Energy Park, and the Water Treatment Plant.

Holland Energy Park has about 11 acres of sustainable landscaping. Outdoor Discovery Center (ODC) Network maintains this acreage, pulling invasive species where necessary and overplanting to keep the landscaping maintained. ODC Network has installed several rain gardens and native landscape beds around the property along with deep-rooted native plants. Native plants can include swamp milkweed, blazing star, purple coneflower, butterfly milkweed, and more.

The Water Treatment Plant has 5 acres of dry native prairie plantings, similar to those at Holland Energy Park. The mix of plants includes deep-rooted species that were purposely chosen to withstand dry conditions without the need for watering while beautifying the landscape with a variety of blooms to last the entire growing season.

The Service Center on Hastings Ave has a 1.5- acre lawn-to-native prairie conversion. This year, we will add another 2.5-acre meadow near the retention pond as well.
