Water Well Rehabilitation in Michigan

Michigan has more households served by water wells than any other state

Water wells are essential for the a large percentage of Michigan’s population, but over time, their performance can deteriorate due to clogging, encrustation, and biological fouling. When a well shows reduced output, higher pumping costs, or degraded water quality, rehabilitation is often a more cost-effective solution than drilling a new one. Cotey Chemical, a pioneer in well maintenance and rehabilitation solutions, offers a comprehensive range of products tailored to tackle the root causes of well decline.

Common Causes of Well Deterioration in Michigan

Water well inefficiencies typically stem from:

  • Iron and manganese oxide buildup

  • Mineral scaling (calcium, magnesium, etc.)

  • Biofouling caused by iron bacteria and sulfate-reducing bacteria 

These issues reduce water flow by clogging screens, gravel packs, and the formation itself.

The Cotey Chemical Approach to Well Rehabilitation

Cotey Chemical has developed a series of specialized products that clean and restore well performance without harming the surrounding aquifer. Our chemical formulations are field-tested and widely used by water well professionals across the U.S. and internationally.

Key Products for Well Rehabilitation

1. Liquid Descaler 

  • A powerful bended organic and mineral acid-based cleaner designed to remove iron, manganese, scale buildup, and biofouling.

  • Contains inhibitors so that its non-corrosive to metal well components when used as directed.

  • Keeps dissolved solids in suspension more efficiently than other mineral acids improving well rinse-out.

2. Dry Acid® Special
  • Dissolves limestone, hard-water scale, rust and corrosion deposits.
  • Keeps dissolved solids in suspension more efficiently than other mineral acids improving well rinse-out.
  • Use to develop new wells producing from limestone or calcareous sand and gravel formations.
  • Use to redevelop old wells that have hard-water scale, rust or corrosion deposits plugging the perforations, screen or formation.
3. Bioclean
  • Removes biofilm produced by slime-forming bacteria, such as that produced by iron-oxidizing and sulfate-reducing bacteria,
  • Improve rinse-out of well treated with mineral acid by dispersing carbonate, sulfate, magnesium and iron deposits.
  • Can be used with Dry Acid® Special to address biofouling
4. Wel-Chlor PLUS
  • Wel-Chlor PLUS compares to Sterilene, a popular sanitizer that is no longer on the market. 
  • Removes and/or precipitates iron, manganese, nitrates and sulfites (not sulfates)
  • Has a neutral pH, therefore needs no pH adjustment. This makes it up to 200 times more effective than other chlorine products that are not pH adjusted.
  • Dissolves 5 x faster than calcium hypochlorite
  • Has a longer shelf life than either calcium or sodium hypochlorite
  • Certified ANSI/NSF Standard 60
