Well Acid Treatment & Rehabilitation in Stayner
Professional acid treatment services for Stayner homes, farms, and businesses.
Stayner's position in the transition zone between the sandy lowlands of the Nottawasaga valley and the bedrock uplands of the Escarpment edge means wells in the area can foul in either of two distinct patterns — sometimes both at once. Wells drawing from the overburden aquifer typically experience iron fouling, while bedrock wells on the higher ground develop calcium carbonate scaling. Mighton's Well Services adapts the rehabilitation chemistry to the specific well: citric or oxalic acid for iron-fouled overburden wells, hydrochloric or sulfamic acid for calcium-scaled bedrock wells. Our diagnostic process — yield test, water analysis, and where possible downhole video inspection — identifies which problem you have before any chemistry is added. Most Stayner wells respond dramatically to targeted rehabilitation, with yield often recovering to original well-record levels.

What to Expect for Acid Treatment in Stayner
When our team arrives at your property in Stayner, here's how the process works. Learn more about our full acid treatment process.
Yield Test & Site Assessment
We start with a controlled drawdown test to measure the well's current yield and recovery rate, comparing it to the original well record. The static water level, pump performance, and any historical yield data tell us how much production has been lost and how quickly the decline has happened. This data is the foundation of the treatment plan.
Water Analysis & Downhole Inspection
We collect water samples for laboratory analysis to identify which minerals are present and at what concentrations. Where conditions allow, we run a submersible video camera through the well to see the deposits directly — calcium scale, iron fouling, biological growth, screen condition. This combined diagnostic tells us exactly what chemistry is needed and what yield improvement to expect.
Treatment Plan & Cost Estimate
Based on the diagnostics, we develop a treatment plan covering acid type, concentration, contact time, and any mechanical agitation needed. We provide a firm written estimate covering pump removal, chemicals, treatment labour, redevelopment, disinfection, and water testing. The plan also identifies any expected yield improvement and the realistic ceiling on what rehabilitation can achieve.
Acid Treatment & Mechanical Agitation
On treatment day, the pump is pulled and the well is prepared. The acid is introduced at the calculated concentration — typically a slow gravity feed or pumped delivery to the fouled zone. Mechanical agitation by surging, brushing, or air injection ensures the acid contacts every fouled surface. Contact time is held to the duration needed for the chemistry to fully dissolve the target deposits.
Redevelopment, Disinfection & Verification
After treatment, the well is thoroughly pumped to remove all dissolved deposits and spent acid, with pH monitoring to confirm full neutralization. The well is shock-disinfected, redeveloped until water runs clear, and the pump is reinstalled. A final drawdown test verifies the yield improvement and a water sample goes to the lab for bacterial and chemical testing. We do not return the well to service until results confirm it is safe.
Common Acid Treatment Issues in Stayner
Mixed iron and calcium fouling on transitional-geology wells
Some Stayner wells, particularly those drilled through overburden into the underlying bedrock, foul with both iron precipitates and calcium scale simultaneously. The iron comes from the overburden aquifer above; the calcium comes from the bedrock fractures below. A single-chemistry treatment will not address both problems.
For mixed-fouling wells, we perform a two-stage rehabilitation: iron-dissolution chemistry first (citric or oxalic acid), then a separate calcium-dissolution stage (hydrochloric or sulfamic acid). Each stage includes proper neutralization before the next chemistry is introduced. The combined treatment is more involved than single-fouling rehabilitation but produces excellent results on these transitional-geology wells.
Older drilled wells with decades of unaddressed calcium scaling
Many bedrock-edge Stayner wells were drilled in the 1970s and 1980s and have never had professional rehabilitation. Calcium carbonate scaling has progressed steadily over decades, with screen openings narrowed and casing walls coated in hard scale. Yield decline has been so gradual that property owners have not noticed how far production has dropped from original well-record values.
For severely scaled bedrock wells, we use higher-concentration hydrochloric acid with extended contact time and mechanical agitation throughout. Multiple treatment cycles may be needed for the worst-case fouling, but yield recovery on previously untreated wells is often dramatic — sometimes restoring more than half the original capacity in a single rehabilitation.
Older galvanized casings requiring careful acid chemistry
Some pre-1980 Stayner wells use galvanized steel casings rather than the modern stainless steel or PVC standard. Galvanized casing is more sensitive to acid chemistry — aggressive treatment can damage the casing material itself, creating leaks or contamination pathways.
We assess casing condition during diagnostic work and adjust acid concentrations and contact times for galvanized installations. Often a lower-concentration treatment with longer contact time produces the same scale dissolution without stressing the casing. For wells with severely deteriorated casings, we may recommend casing liner installation alongside rehabilitation.
Test Older Stayner Wells Before Replacing Them
If your Stayner well is producing less than it used to and you are considering replacement, get a yield test and water analysis first. Many wells flagged as "needing replacement" actually have decades of treatable fouling and can be rehabilitated at a quarter the cost of new drilling. The diagnostic work is inexpensive and saves you from spending $20,000+ on a new well when $5,000 of rehabilitation would have done the job.
