About Well Drilling in Jonesboro

Water well drilling is the process of boring a hole into the earth to access underground aquifers that provide fresh water for drinking, irrigation, and household use. Approximately 43 million Americans rely on private wells as their primary water source. Residential wells typically range from 100 to 500 feet deep depending on the local geology and water table depth, though some areas require wells exceeding 1,000 feet. The drilling method depends on the geological conditions — rotary drilling is most common for deep wells through rock formations, while cable tool (percussion) drilling works well in unconsolidated materials like sand and gravel. After drilling, the well is cased with steel or PVC pipe to prevent contamination from surface water, and a submersible pump is installed at the appropriate depth to bring water to the surface. A pressure tank system in your home maintains consistent water pressure. The complete system includes the well itself, casing, pump, pressure tank, and connection piping. New wells require permits from state or local water authorities, and most states mandate a water quality test before the well can be used. Costs vary enormously by region and depth — from $6,000 in the Southeast to over $30,000 in areas with deep bedrock or difficult drilling conditions.

What Jonesboro Homeowners Should Know

Local Soil Conditions: Craighead County soils are dominated by the Crowley silt loam, Sharkey clay, and Memphis silt loam — soils of the Lower Mississippi Alluvial Plain and adjacent loessial uplands. Crowley silt loam is a poorly drained Alfisol of the Arkansas Grand Prairie with an argillic Bt horizon at 8-16 inches (clay 30-45%) and a seasonal water table within 12-18 inches. Sharkey clay — a Vertisol with 60-80% smectite clay — covers low prairie and backswamp positions with near-zero permeability and seasonal water tables near the surface. Memphis silt loam on Crowley's Ridge loessial uplands is a well-drained Alfisol with excellent permeability and water tables at 48-72 inches.

Water Table: Memphis silt loam on Crowley's Ridge: 48-72 inches. Crowley silt loam on Grand Prairie: 12-18 inches seasonally. Sharkey clay in backswamps and bayous: 0-12 inches year-round.

Climate Impact: Jonesboro has a humid subtropical climate with hot, humid summers and cold winters with occasional ice storms. Annual rainfall averages 50 inches. Northeast Arkansas's position at the edge of the Mississippi Alluvial Plain means spring flooding of the St. Francis, Cache, and Black rivers is a recurring event in the lowland portions of Craighead County. The contrast between the well-drained Crowley's Ridge uplands and the seasonally flooded lowlands defines the septic landscape.

Signs You Need Well Drilling

  • Building a new home without access to municipal water supply
  • Existing well has gone dry or produces insufficient water
  • Water quality has deteriorated beyond what treatment can fix
  • Adding irrigation needs that exceed existing well capacity
  • Existing well is contaminated and cannot be rehabilitated

The Well Drilling Process

  1. 1 Site assessment and hydrogeological survey to identify the best drilling location
  2. 2 Obtain required drilling permits from state or local water authority
  3. 3 Mobilize drilling rig and begin boring through soil and rock layers
  4. 4 Install well casing and screen at the appropriate aquifer depth
  5. 5 Develop the well by pumping to clear drilling debris and maximize flow
  6. 6 Install submersible pump, pressure tank, and connection piping
  7. 7 Conduct water quality testing and obtain certificate of completion

Frequently Asked Questions — Jonesboro

What is Crowley's Ridge and why does it matter for septic systems near Jonesboro?
Crowley's Ridge is a unique geomorphic feature — a narrow loessial ridge of wind-blown Pleistocene silt rising 100-200 feet above the Mississippi Alluvial Plain. Jonesboro sits on this ridge, which runs north-south through eastern Arkansas and into Missouri. The ridge's Memphis silt loam soils are well-drained and excellent for conventional septic systems. The surrounding Grand Prairie and lowland areas have Crowley silt loam and Sharkey clay soils that are poorly drained and require engineered systems. Whether your property is on the ridge or in the lowlands is the most important site factor in Craighead County.
How much does septic pumping cost in Jonesboro?
Septic pumping in Jonesboro and Craighead County ranges from $225 to $410. Arkansas's lower cost of living is reflected in competitive septic pricing. Standard residential tanks average $245-$335. The northeast Arkansas region has established contractors serving both ridge communities and Delta lowland properties. ADH recommends 3-5 year pumping intervals.
Does Arkansas State University affect septic demand in Jonesboro?
ASU's approximately 13,000 students create off-campus rental housing demand in Jonesboro's suburban fringe, including some properties on individual septic systems. ASU's campus itself is on Jonesboro's municipal sewer. Student rental properties on septic experience higher water use than typical households. Property owners managing student rentals should pump tanks every 2-3 years and advise tenants not to flush wipes, hygiene products, or other non-biodegradable materials.
Can properties in the Arkansas Grand Prairie around Jonesboro use conventional septic systems?
It depends on the specific site conditions. Crowley silt loam soils on the Grand Prairie have seasonal water tables within 12-18 inches and moderate-to-slow permeability — conditions that are at or below Arkansas ADH's threshold for conventional gravity systems. Many Grand Prairie properties require pressure-dosed systems or aerobic treatment units. Sharkey clay positions in lower prairie areas are unsuitable for any conventional in-ground system and require ATU with spray disposal. A site evaluation by ADH or a licensed evaluator will determine what is permittable for a specific lot.
Are there areas of Craighead County subject to Mississippi River or tributary flooding that affect septic systems?
Yes. The St. Francis River, Cache River, and Black River drainage systems flow through the lowland portions of Craighead County and experience spring flooding in high water years. Properties in FEMA-designated 100-year floodplains along these rivers are at risk of septic system inundation. After flood events, tanks should be inspected for damage and pumped if floodwater entered the tank. The lowland Sharkey clay areas that flood most regularly are the same areas where conventional in-ground systems are not permittable — the two constraints (flooding and soil unsuitability) reinforce each other in discouraging residential development in these areas.
