Engineer Soil Environment case studies
Engineer Soil Environment · Put your knowledge to work in context.
The Engineer Soil Environment credential is a professional engineering qualification for people who investigate, design and manage work on contaminated and otherwise disturbed soil. It suits environmental, geotechnical and civil engineers, remediation designers, site assessment specialists and regulators who need to show competence across the full soil environment workflow rather than in a single niche. The Engineer Soil Environment case studies are 5 cases and about 4,588 words.
1Twelve Years of Manure on a Tile-Drained Sandy Loam: Does the Nutrient Budget Protect the Stream?
A 48-ha grain farm on a sandy loam (7% clay, 1.4% organic carbon) has received liquid swine manure at agronomic rates for 12 years. Grid soil sampling (one sample per 0.4 ha, 0–15 cm) returns Mehlich-3 phosphorus averaging 210 mg/kg, with a maximum of 340 mg/kg; subsurface samples at 15–45 cm average 55 mg/kg.

A former metal-parts degreaser operated for 28 years over a 0.6-ha site. The geology is 6–9 m of silty clay with thin, discontinuous sand lenses at 4.5–5.5 m; groundwater sits at 6 m.

At a former smelter site, a monitoring well (MW-7) is screened in a sandy aquifer 7–9 m below grade, downgradient of a slag pile. The QAPP requires low-flow purging at ≤0.3 L/min until pH, specific conductance, and turbidity stabilize, then field filtration at 0.45 µm and nitric acid preservation for dissolved metals.

A 1.1-ha former orchard is being redeveloped as a childcare centre with a fenced play area, a building, and a parking lot. Surface soil (0–15 cm) averages arsenic 62 mg/kg and lead 460 mg/kg across the play area; the 15–60 cm layer averages arsenic 14 mg/kg and lead 90 mg/kg.
