Evanston’s Hidden Crisis: How Lake Michigan Algae Blooms Are Turning Your Home’s Plumbing Into a Battleground

As 2025 unfolds, Evanston homeowners are facing an unprecedented challenge that’s been quietly building beneath the surface. The Agency’s 2025 Algal Bloom Monitoring Program consists of two parts: Routine Monitoring and Event Response. Routine Monitoring is conducted at public-water-supply intakes, lake beaches, and public-water-supply intakes in Lake Michigan. What this means for residents is that local water meets state and federal safety standards but often smells earthy or musty due to seasonal algae blooms, and the problem is getting worse.

The Growing Algae Problem in Lake Michigan

Blue-green algae can reproduce very quickly in warm, shallow, undisturbed-surface water that receives a lot of sunlight. This rapid growth of algae is referred to as a “bloom.” Algal blooms can discolor the water or produce floating scums on the surface of the water, especially along shorelines. For Evanston residents, this natural phenomenon has evolved into a serious infrastructure challenge.

The Illinois EPA has been monitoring this issue closely. Illinois EPA intends to collect microcystin, cylindrospermopsin, anatoxin-a, and saxitoxin samples at four Lake Michigan intakes between April and November. Unfortunately, recent trends show that “There is good evidence that these blooms are responding to climate change. In the Great Lakes, we’re seeing that the bloom season is getting longer as the waters get warmer.”

How Algae Blooms Impact Your Home’s Plumbing

The connection between Lake Michigan algae blooms and residential plumbing problems isn’t immediately obvious, but it’s very real. It takes four to eight hours for the water to flow through the settling basins, giving time for the floc to settle, carrying with it suspended matter, bacteria and algae. In this process more than 90% of all suspended impurities are removed. However, the remaining algae particles and their byproducts can still cause significant issues in home plumbing systems.

When algae-laden water enters your home’s plumbing system, several problems can occur:

• Filter Clogging: When algae starts growing inside your filter housing, it clings to surfaces, clogs filter media, and can throw your whole system off balance. It slows water flow, reduces your filter’s effectiveness, and if left alone too long, can even shorten the lifespan of your unit.
• Pipe Blockages: Algae and bacteria multiply rapidly and clog filters before replacement is due.
• Odor Issues: Algae can give your water a swampy smell and leave behind green or brown residue that makes everything look and feel… off.
• Fixture Problems: Algae particles can accumulate in faucet aerators, showerheads, and appliance screens, reducing water pressure and flow.

Why Evanston is Particularly Vulnerable

Evanston’s water treatment process, while effective, isn’t immune to the increasing severity of algae blooms. Water is drawn from Lake Michigan through large intake pipes laying in trenches along the lake bottom offshore. Lake water flows (thanks, gravity!) through the intake pipes into three 22-foot-wide suction wells with mechanical screens to remove any trash from entering the raw water (low lift) pumps.

The challenge lies in the fact that nutrient-rich runoff from farm fields, as well as cities and towns, can fuel the growth of these tiny organisms, creating what’s known as harmful algal blooms. These blooms can contaminate water supplies, forcing municipal water systems to temporarily shut down and disrupting life for local residents.

Signs Your Home is Affected

Evanston homeowners should watch for these warning signs that algae-related issues may be affecting their plumbing:

• Reduced water pressure at faucets and showerheads
• Musty or earthy odors from tap water
• Discolored water, particularly with a greenish tint
• Frequent filter replacements needed
• Appliances like dishwashers or washing machines showing reduced performance
