Do you need a permit to hydrofrack a well in Maryland?

No well construction permit is needed if the job only reworks the well and does not deepen it. The approving authority still gets at least 2 business days of notice. The driller then files a Hydrofracture of Well Report within 45 days, with yield test data.

Is hydrofracking cheaper than drilling a new well?

By the published ranges, yes, if the job works. The Well Guide puts hydrofracking at $1,500 to $3,000, and a new well at $8,000 to $20,000. Newfoundland and Labrador's fact sheet says to weigh a new well's infrastructure too. A job that adds too little water can mean paying for both.

Is well hydrofracking the same as oil and gas fracking?

No. New Hampshire's environmental agency says drinking water well hydrofracking does not use acids, diesel or polymers, unlike oil well fracking. It also does not use propping mixtures such as sand. The agency's fact sheet, accurate as of July 2019, reports no recorded environmental degradation from it.

Can hydrofracking hurt a neighbor's well?

Some risk exists. Newfoundland and Labrador's fact sheet warns about a well in the same fracture trend, or 20 to 30 meters away. Maryland requires the well to be at least 50 feet from any other potable water supply well. Within 100 feet of another water supply well, written approval is required.

Can you hydrofrack a well in limestone in Maryland?

Only with the approving authority's written permission. Maryland's well rules treat carbonate rocks as Hydrogeologic Area 5, and hydrofracturing there needs that permission. The Frederick and Hagerstown valleys are underlain mostly by limestone and dolomite, both carbonate rocks. If your well sits in that rock, that permission comes before any hydrofracking work.

What if hydrofracking does not add enough water?

Then storage, deepening or a new well comes next. Maryland's rule says that when sustained yield cannot meet 500 gallons in a 2-hour period, sufficient storage must be provided. A yield test shows where the well stands. Water storage and holding tanks are among the work we offer.

How Much Does Hydrofracking a Well Cost in Maryland?

Four published sources put well hydrofracking cost between $1,500 and $7,000. The Well Guide lists a new well at $8,000 to $20,000, and none of these is a HydroWells quote. In Maryland, hydrofracking a low-yield well needs no well construction permit. Your county’s approving authority still gets notice, and the driller files a report with yield data.

A well that runs short in August, or quits halfway through the laundry, raises two questions. What does hydrofracking cost, and does it beat deepening the well, drilling a new one or adding storage? The ranges below come from published cost guides and well companies outside Maryland. None of them is a HydroWells price or a Maryland quote.

We are based in Poolesville and Dickerson and work on wells across Montgomery, Frederick, Carroll, Howard, Washington and Baltimore County. Maryland’s well rules add steps the national guides leave out, and they can change which option makes sense. Your own number comes from a free estimate, written after a look at the well and the property.

What does it cost to hydrofrack a well?

Four published sources put a residential hydrofracking job between $1,500 and $7,000. The Well Guide lists $1,500 to $3,000 for a low-yield bedrock well. Today’s Homeowner says homeowners typically pay $2,000 to $7,000, depending on the type of job. A Mid-Atlantic well company lists $2,500 to $4,500 for an existing well.

The fourth source is a Washington State well equipment company, which puts the job typically between $2,000 and $5,000. A well company in north central Washington State publishes a higher range, $5,000 to $10,000. That company says a new well in its region commonly runs $25,000 to $50,000 or more. Today’s Homeowner dates from October 2024 and The Well Guide from October 2026.

What moves the price of a hydrofracking job?

The type of job moves the price. Today’s Homeowner ties its range to the type of hydrofracking. New Hampshire’s environmental agency says zone isolation, which uses two packers in the borehole, is much more expensive and time-consuming. It says that method is generally used only on very difficult wells or public supply wells.

New Hampshire’s environmental agency says many contractors leave yield testing out of the contract. In Maryland, yield test data must go in with the Hydrofracture of Well Report, so the job needs that test. All piping and pumps must also come out of the well first, Newfoundland and Labrador’s fact sheet says. Ask these questions when you compare written quotes:

Is pulling and resetting the pump in the price?
How many packer settings does the price cover?
Is the injection water from a potable or approved source, as Maryland requires?
Is the yield test in the price?
What happens if the yield does not improve?

How much more water will hydrofracking add?

The gain is often modest, and COMAR itself calls hydrofracturing an attempt to increase yield. New Hampshire’s environmental agency says increases, if successful, are generally modest. It says a typical well yield after the work is 1 to 10 gallons per minute. Today’s Homeowner says a successful job can add one to 10 gallons per minute.

New Hampshire’s agency says a modest gain may be a significant increase when the starting yield was very low. It also says that in some instances, because of geologic conditions, hydrofracking will not increase yield. The Well Guide’s reported estimate of success is 70 to 97 percent, depending on source and geology. A Maryland Geological Survey study of 2,315 wells found that individual well yields still cannot be predicted.

Should you hydrofrack, deepen, drill new or add storage?

Start with what the house needs and what the well makes. Maryland’s standard for a home water system is 500 gallons or more in 2 hours, at least once a day. If the well’s sustained yield cannot meet that, the rule calls for sufficient storage. The Well Guide prices deepening and a new well above well hydrofracking work.

Maryland’s rule sets the amount of storage by subtracting the well’s yield over 2 hours from 500 gallons. A well making 2 gallons per minute gives 240 gallons in 2 hours, so it needs 260 gallons stored. Water standing in the well counts toward that, at 1.5 gallons per foot in a 6-inch well. That count runs from the static water level down to 10 feet above the bottom.

A holding tank is the other way to add storage, at the two prices in the table above. Deepening adds borehole and standing water, at $3,000 to $10,000 in The Well Guide, which calls the outcome uncertain. Deepening needs no construction permit if the well’s identification number is verifiable, except where water quality problems are known. Without that number, the driller applies for one.

A new or replacement well needs its own well construction permit, plus its own connection to the house. The Well Guide lists $8,000 to $20,000, and its Mid-Atlantic table lists $7,000 to $18,000 for a complete system. Our well drilling cost guide explains what moves that number. Sealing the old well adds to it, because Maryland requires an abandoned well to be filled and sealed.

What does Maryland require for hydrofracking a well?

COMAR 26.04.04.11 says reworking that does not deepen the well needs no well construction permit. COMAR 26.04.04.28 requires at least 2 business days of notice to the approving authority. The driller then files a Hydrofracture of Well Report within 45 days.

Only someone with a Maryland well driller’s license may do the work, or a subcontractor under that driller’s direct supervision. HydroWells is licensed through the Maryland State Board of Well Drillers. Maryland requires the total volume of water put into the well to come out before the yield test. Yield test data then goes in with the report, which puts the result on file with the approving authority.

When is hydrofracking the wrong fix?

Hydrofracking is the wrong fix when the problem sits somewhere else or the site cannot qualify. It applies to bedrock wells only. In Maryland, the rock type and what sits nearby can require written approval or rule the job out.

Today’s Homeowner says the pump, pressure tank or mineral scale buildup can mimic a dry well. Those get checked first. When iron crust or sediment sits inside the well, well cleaning and rehabilitation may fit better. A casing or grout problem calls for its own fix first. COMAR 26.04.04.28 also requires approval for a well not built to the state’s construction rules, plus these limits:

Carbonate rock, Hydrogeologic Area 5: written permission required first
Another water supply well within 100 feet: written approval required
Any other potable water supply well: at least 50 feet away
Landfill or known contamination within 500 feet: written approval required
Any potential source of contamination: at least 100 feet away
