Water Quality Problems & Well Water Repair in Ortonville, MI & Beyond

If your well water smells like rotten eggs, looks rusty, tastes salty, or suddenly loses pressure, something in your system needs attention. Hydrogen sulfide occurs naturally in groundwater due to the activities of sulfur-reducing bacteria.

Common signs of well water contamination in Michigan, include strange odors, unusual tastes, and discolored water. Sediment particles or cloudy, dirty water are also major signs of contamination. Regular visual inspections of the well system are necessary to monitor water quality changes. If family members experience unexplained diarrhea, vomiting, nausea, or fever, it could indicate bacteriological contamination.

Mike LaLone Well & Pump Service diagnoses and repairs well water quality problems for homeowners in Ortonville, MI and throughout Southeast Michigan. From iron buildup to sulfur odors and contamination concerns, we identify the source and provide long-term solutions. Hydrogen sulfide in water can cause corrosion of metals in a plumbing system. Red or brown stains in water indicate iron, blue or green stains indicate copper, and black or gray stains suggest manganese. No matter the water quality issue, we're here to help!

Sources of Contamination

Hydrogen sulfide gas can naturally occur in groundwater, particularly in areas rich in organic material. Sulfur bacteria flourish in low oxygen environments, such as deep wells and sections of the plumbing system that don't get much fresh water flow. These bacteria feed on organic material and other contaminants, producing hydrogen sulfide gas as a byproduct.

The presence of iron and manganese in the water supply can further encourage the growth of sulfur bacteria, compounding odor and taste problems. In addition to natural sources, human activities like agricultural runoff and industrial waste can introduce other contaminants into your well water. This makes regular testing and proactive maintenance essential to prevent contamination and protect your water supply from both natural and man-made threats.

Common well water quality problems:

  • Hard water - dissolved magnesium and calcium
  • A high concentration of salt or iron
  • Methane Gas (a rotten egg smell)
  • Oil spills or accumulated leakage
  • Bacteria, usually from the septic tank
  • Barnyard Runoff
  • Pesticides and Fertilizers
  • Contamination from a nearby abandoned well

Rotten Egg Smell in Well Water

That strong sulfur or rotten egg smell is typically caused by hydrogen sulfide gas or sulfur bacteria in the groundwater. Hydrogen sulfide occurs naturally in groundwater, especially in wells drilled in shale or sandstone, or near coal or oil fields. The sulfur smell in well water is primarily due to hydrogen sulfide gas produced by sulfur bacteria. Groundwater contamination can lead to the growth of sulfur bacteria, which produce hydrogen sulfide gas.

Hydrogen sulfide is more commonly found in groundwater supplies than in surface water. A rotten egg smell often indicates sulfur bacteria or hydrogen sulfide gas. Hydrogen sulfide can form as a result of chemical reactions in the hot water heater, especially involving the magnesium rod (anode rod). The magnesium rod in the water heater tank provides corrosion protection but can also contribute to hydrogen sulfide production.

Replacing or maintaining the anode rod can reduce corrosion and help address sulfur odors. Regular cleaning of your water heater can help prevent odors caused by bacterial growth. The offensive odor of hydrogen sulfide generally makes testing unnecessary, as most people can detect it easily, but testing well water for hydrogen sulfide can confirm if groundwater contamination is the source. Hydrogen sulfide occurs as a result of sulfur-reducing bacteria in low-oxygen environments.

If both hot water and cold water have a sulfur smell, the issue may involve the well and plumbing system; if only hot water is affected, the water heater may be the source. Testing both hot and cold water can help identify the source of the odor. Letting water sit in the pipes for a few hours before testing can help diagnose sulfur smells.

Depending on the issue, we may recommend:

  • Shock chlorination
  • Aeration systems
  • Carbon filtration
  • Hydrogen peroxide treatment
  • Vent installation
  • Well relocation (in rare cases)

Hydrogen sulfide can cause yellow or black greasy stains on fixtures, blacken silverware, and discolor copper and brass utensils. It can also produce black or gray stains on plumbing fixtures, silverware, or laundry. Insoluble sulfur can be produced during water treatment and may appear as black or gray stains. Hydrogen sulfide encourages the growth of nuisance bacteria, which can clog plumbing, water heaters, and irrigation systems, and reduce water flow.

Sulfur bacteria can produce slime that clogs plumbing, water heaters, and irrigation systems. Hydrogen sulfide gas can cause corrosion of metals in a plumbing system. When hydrogen sulfide forms metallic sulfides, it can cause yellow or black greasy stains inside pipes.

Don't ignore sulfur smells; they often worsen over time!


Well Water Testing in Ortonville, MI

If your water's color, smell, or taste changes, testing is the first step—a proper water test confirms what contaminants or bacteria are present. Regular inspections of your well infrastructure can help prevent contamination issues before they lead to odor problems.

We test for:

  • Iron and manganese
  • Sulfur compounds (collect water samples for the hydrogen sulfide test at the well site)
  • Coliform bacteria
  • Nitrates
  • Salt contamination
  • Sediment levels
  • Other chemicals

Testing for contaminants like hydrogen sulfide and coliform bacteria can reveal broader water quality issues. Many dangerous well water contaminants are colorless, odorless, and tasteless, making professional testing essential. Annual water testing for bacteria and nitrates is recommended. Well water should also be tested immediately after events like heavy flooding or drought. 

Frequent testing identifies early signs of contamination, allowing for timely intervention. Home water test kits offer a convenient and cost-effective way to identify potential water quality issues, but professional testing through certified labs should be used for accurate results. If a test for harmful bacteria or chemicals is positive, do not use the water for drinking, cooking, or making ice. Water testing labs and other professionals can provide further information on specific steps for testing.

Regular testing protects your family and your plumbing system.
