The Best Well Drillers in Monterey County CA Are the Ones Proven Safe To Hire
The state of California requires water well drillers in Monterey County CA to be licensed as well drilling contractors by the state in order to install and repair water wells and pumps by boring, drilling, casing, cementing and cleaning. The state also requires they show proof of workers' comp insurance.
But the state license is no guarantee that any particular well drilling company is doing business ethically, providing real value, and satisfying customers. Likewise, there is no legal requirement that water well drilling contractors in Monterey County first show proof of liability insurance which is critical to reimburse you in the event of any damage that occurs.
This makes it all the more significant that all well drilling contractors in Monterey County CA who bear The Prime Buyer's Report-TOP 10 symbol have been cleared by our research staff as passing all the requirements for Prime Buyer's Report-TOP 10 status such as survey phone calls to previous customers to verify high satisfaction, good complaint record, verified license, liability insurance, only employees legal to work in the U.S., and more.
Costs of well drilling contractors in Monterey County CA: Before preparing a bid, well drilling companies should be learning as much as possible about your property, other wells in the region, local regulations, and your intended use of the water well. A well drilling contractor who prepares a bid without this assessment is unlikely to determine the right cost and equipment necessary to do your project correctly and on time. Many other things will determine final cost such as the type of well, the well drilling method used, choices in materials such as steel well casing versus plastic, etc. Those variables can mean that a bid that seems cheaper really isn't because it's not bidding on the exact same things as another.
The following information explains some of the differences in well drilling methods, materials, and the process that affect cost, allowing you to understand bids from well drilling contractors in Monterey County and ask the right questions of them.
BEFORE DRILLING A WELL
Well drilling contractors should start with a survey of your property and the surrounding area. The well driller can't always determine in advance how deep he must drill to reach an adequate water supply but neighboring wells can be an indication. Surveys of existing wells may be available from your city or from Monterey County as well as regional groundwater assessment results indicating the local groundwater quality.
Choosing the exact well site may include considering potential future plans for your property but the well drilling contractor will have something to say regarding proper site selection to prevent well contamination from run-off and other sources. Well drilling contractors must be experts in water tables and hydrology, local soil conditions, and know the regulations that dictate the minimum distance the well must be from other structures, power lines, sewer lines and septic systems.
The well drilling contractor will drill a test hole. After drilling the test hole choices must be made regarding the well depth, type of well, casing material size and thickness, intake design, formation seal, and provisions for future monitoring and maintenance.
During drilling of the test hole, the well drilling contractor should take soil and rock samples at various depths and record it. This allows them to indentify water aquifers with the best potential for your water well. Usually a well is drilled to the bottom of the available aquifer to get the highest possible water yield from the well.
WELL DRILLING PROCESS & METHODS
The well drilling contractors create a well shaft, or borehole which is lined with a pipe (steel or plastic) called the well casing. The top of the well that you can see is called the wellhead and this includes the part of the well casing that extends above the soil line which is surrounded by a concrete slab. Older wells may have casings that don't rise above ground level but new wells are not installed that way for safety reasons.
Well drilling contractors provide two types of wells; bored wells and drilled wells.
Bored Wells: When groundwater is relatively close to the surface, usually under 100ft, a bored well is an option. Well drilling companies create bored wells using a rotary bucket auger and they have a larger diameter compared to drilled wells. This larger diameter can serve as a water storage reservoir for use during periods of high demand. The disadvantages of relying on a shallow water source closer to the surface are that it requires rainwater to recharge, meaning water shortages may happen during long dry spells, and freezing during winter in cold climates.
Drilled Wells: Smaller in diameter than bored wells, they can go to greater depths, such as 1,000ft compared to the 100ft or less of a bored well. An aquifer at this greater depth is usually less vulnerable to pollution and contamination than ones closer to the surface and the water supply tends to be more reliable as it's less affected by weather. Well drilling contractors create drilled wells by either the rotary method or the percussion method (also called "cable tool drilled")
Rotary Drilling for a Drilled Well-Uses a drill bit on the end of a rotating drillstem (rotary drilling)
Percussion Drilling (or cable tool drilled for a Drilled Well - Repeated dropping of a heavy drill bit into the earth. Well drilling companies inject fluid or mud to mix with the resulting loose material and the mixture is removed using a bailer or sand pump. Percussion drilling can take longer to drill a water well compared to rotary drilling but when aquifers are low-yielding they may be more easily indentified.
AFTER THE WELL DRILLING
After the well contractor has drilled the well and the equipment is installed, three more steps must be done before the water well can be used: 1) Well Development 2) Yield Test 3) Disinfecting
The well drilling contractor should remove fine sediment and drilling fluid from the well bottom to maximize the amount of water it produces, in a process called well development. Larger particles are left behind to form a natural filter. If there are not enough naturally occurring, the well contractor may need to install an artificial filter pack.
A yield test or pump test allows the well drilling contractor to determine the rate at which to pump the well and how deep to place the well pump.
The well drilling contractor will disinfect the well and different regions can have different regulations on how long well disinfecting must be done and using what substances.

• How will they handle cost overruns due to inadequate planning? Do they guarantee to absorb any such costs or will they expect you to?
• Do they own all the equipment that will be used, or will they rent any of it? Rentals may not always be consistently available to the contractor and can cause time delays.
