IA Well Driller study plan

Map the regulatory architecture: locate the Iowa water well statute (Iowa Code ch. 455B) and the DNR well construction rules (567 IAC ch. 39), then chart which rule covers siting, casing, grouting, disinfection, and plugging.

Summarize contractor certification obligations in your own words - who must hold certification, experience/apprentice requirements, application, fee and renewal cycle, and reporting duties to the Department.

Define 25 core regulatory terms (well, boring, annular space, grout, pitless adapter, abandonment, etc.) without quoting rule language, then self-quiz until you score 23/25 closed-book.

Work 30 rule-based practice items and, for every miss, write the rule section that resolves it so you build a personal citation index.

Build a setback table for every isolation distance the rules impose (property lines, septic systems and drainfields, sewers, livestock areas, fuel storage, surface water, other wells, buildings) and verify each number against rule text rather than memory.

Apply the table to five written parcel scenarios and decide siting, minimum separation, and any required variance or alternate construction.

Explain source water protection concepts - wellhead protection areas, delineation basics, potential contaminant sources, and how grouting and proper abandonment protect the aquifer.

List the conditions that trigger rejection or re-siting of a proposed well and state the rule basis for each.

Compare rotary mud, air rotary, cable tool, and hollow-stem auger: describe cutting removal, wall stability, sample quality, applicable formations, and typical depth limits.

Sequence borehole construction from predrilling to casing set: overburden drilling, casing setting depth, seating into confining material or bedrock, and temporary versus permanent casing decisions.

Read a described stratigraphic sequence (sand/gravel/silt/clay/limestone) and identify the confining layer, the target aquifer, and where the seal must land.

Write three borehole logs from supplied drill-cutting and sample descriptions, including depth, material, water strike, and casing/grout intervals.

Explain how unconsolidated versus bedrock formations change drilling fluid, hole diameter, and casing length choices.

Size casing and screen for a stated pump capacity and formation grain size, and justify slot size, screen length, and gravel pack where required.

Compute annular space volume and grout quantity for five hole/casing diameter and depth combinations, including washout allowance and neat-cement versus bentonite yield.

Describe acceptable grouting methods (tremie/positive displacement, pumping from bottom up), placement depth, lift and waiting requirements, and how placement is verified.

Catalogue the common sealing failures - bridging, voids, wrong slurry density, grouting before casing is centered - and the corrective action for each.

Practice 20 mixed items covering casing, screen, and grouting and log every error with the controlling rule or standard.
