Across
- 3. Area of land that catches precipitation and drains into surface water bodies.
- 5. Layer of porous substrate that contains and transmits groundwater.
- 7. A wall constructed using plant material that naturally filters indoor air pollutants.
- 11. Occur in dry soil; a type of preferential pathway where water/contaminant infiltrates with gravity but doesn’t infiltrate evenly thus creating finger like patterns.
- 12. Process where there is no transfer of heat or energy across an air parcels boundaries.
- 13. Variation in amount of contaminant in soils due to spatial differences in contaminant release.
- 14. Top of area in soil profile that is saturated with groundwater.
- 15. Treatment systems that use natural processes involving wetland vegetation, soils, and microbial populations to improve water quality.
- 16. Ease of movement through soil or rock pore spaces.
- 19. Process distributing contaminant, elongating it as it moves downstream because water at the center of the river moves faster related to friction at river bottom and riverbanks.
- 21. Large pore spaces in soil; a type of preferential pathway that allows easy movement of water and air.
- 23. Potentially contaminated land due to historical industrial and commercial land uses.
- 24. A phased approach to evaluate environmental conditions at a brownfield site.
- 26. Remediation technique where the environmental medium is left in place and remediated.
- 27. A report completed by a qualified person and filed on the Environmental Site Registry that documents the results of one or more environmental site assessments.
- 28. Cells of atmospheric circulation related to heat being transported to the poles.
- 29. System that is man-made or largely controlled by anthropogenic activities.
- 30. Air pollution containing gases and aerosol particles that results in poor air quality and reduced visibility.
- 31. An innovative approach to land development mimicking the natural movement of water in order to manage stormwater.
- 33. Describes how easily surface or groundwater can become polluted.
- 37. Step in the Environmental Site Assessment process that is focused on a high-level, preliminary assessment of a site based on background research.
- 39. Condition in the atmosphere where temperature increases with elevation.
- 40. A subsurface drainage system used to remove excess water from agricultural fields.
- 42. Particles that spend the majority of their time on the river bottom.
- 43. A scientific examination of the nature and magnitude of contamination risk.
- 44. Amount of time water stays in a lake based on volume and water loss.
- 46. Variation in amount of contaminant in soils often due to temporal differences in contaminant release.
Down
- 1. Difference in hydraulic head between two points such that water flows from high hydraulic head to low hydraulic head.
- 2. Measures used to help achieve target levels of risk that are equal to site condition standards.
- 4. Diagram providing a visualization of groundwater flow based on lines of equal hydraulic head.
- 6. Remediation technique where the environmental medium is removed from the site and remediated.
- 7. Point where water vapor in air begins to condense forming clouds.
- 8. Designation of the individual who can complete an Environmental Site Assessment (based on profession, education, and experience).
- 9. Standards based on property type that identifies that maximum allowable concentration of contaminants in soil and water on a property.
- 10. Lapse rate describing the rate an air parcel cools as it rises.
- 16. Height of the water table.
- 17. Type of aquifer where water can flow directly between the soil surface and an aquifer.
- 18. The use of various techniques to reduce or eliminate a contaminant.
- 20. Circular motion of water when water passes an obstacle and water move contrary to direction of the main current.
- 22. Activities used to mitigate or prevent environmental issues.
- 25. Describes how quickly water moves vertically through the soil profile from the soil surface to an aquifer.
- 32. Defined, self-contained body of air.
- 34. Lapse rate describing the rate of temperature decrease with increased elevation.
- 35. Type of aquifer where an impermeable layer of rock or substrate restricts movement through soils above an aquifer.
- 36. Capture zone describing how quickly water moves horizontally through the aquifer to the well or from upstream to downstream in surface water bodies.
- 38. Type of infrastructure that uses natural elements or ecosystem features as components of design and development.
- 41. Step in the Environmental Site Assessment process that involves a detailed investigation and assessment of a property to determine the type and extent of contamination.
- 45. Probability that a contaminant will cause human or environmental harm.
