NY Well Driller study guide
NY Well Driller · Work through your exam, one topic at a time.
The New York Water Well Driller Certification Exam is the assessment that New York State uses in connection with the certification required to drill, deepen, and decommission water wells professionally in the state. It is aimed at working drillers, drilling company owners and supervisors, and people entering the trade who need to demonstrate competence before offering well construction services to the public. The NY Well Driller study guide has 8 sections and about 2,780 words.
01Well Siting, Geology, and Hydrogeology
This domain tests whether you can place a well where it stays sanitary and yields usable water. New York’s well construction standards (10 NYCRR Appendix 5-B) set minimum separations: keep a well at least 50 ft from septic tanks and sewer lines and 100 ft from septic absorption fields, manure storage, and animal yards; local health departments can require more.
387 words, about 2 min02Well Design and Construction
This domain tests the physical well: casing, annular seal, screen, wellhead, and the details that keep surface water and shallow contamination out. Under Appendix 5-B, casing must be watertight, extend above grade or floor, and be grouted to prevent annular migration.
379 words, about 2 min03Drilling Methods, Equipment, and Operations
This domain tests method selection and real-time operations: rotary air, mud rotary, cable tool, hollow-stem auger, and reverse circulation. In New York’s glacial deposits, auger and mud rotary are common for unconsolidated material; air rotary and down-the-hole hammer are common in bedrock.
344 words, about 2 min04Well Development, Testing, and Disinfection
This domain tests what happens after drilling: removing drilling fines, proving yield, and sanitizing the well. Development methods include surging, bailing, airlifting, jetting, and overpumping.
324 words, about 2 min05Pumps, Water Systems, and Controls
This domain tests pump selection, setting depth, pressure control, and system protection. Common pump types are submersible, jet, and centrifugal.
359 words, about 2 min06Well Abandonment and Decommissioning
This domain tests how to permanently close a well so it cannot act as a pathway for contamination or intermix aquifers. Abandonment is not “fill the hole with dirt.” New York expects proper sealing with approved materials, removal or cutting of casing, and documentation.
326 words, about 2 min07Regulations, Permits, and Reporting
This domain tests the administrative side: who may drill, what approvals are needed, and what must be reported. New York licenses water well drillers through the Department of Environmental Conservation (DEC); well construction standards are in the Sanitary Code (10 NYCRR Appendix 5-B), and public water systems are regulated by the Department of Health.
338 words, about 2 min08Safety, Environmental Protection, and Professional Practice
This domain tests field safety and environmental control: silica dust, electrical hazards, confined spaces, traffic, spills, and waste. Drilling generates respirable crystalline silica when rock or concrete is cut; control it with water spray, dust collection, and appropriate respiratory protection.
