Natural soil regeneration on such a hostile site could take up to 60 years. By using these specific worm varieties, the project aims to complete the process in just . Alongside the worms, around 250,000 trees, including willow and alder, have been planted. These trees perform a dual role: their roots extract remaining contaminants, and they can eventually be harvested for wood burning or manufacturing. Project Partners This rescue plan was developed by a collaboration between: HL Banks : A local landscaping and earthmoving company. Scottish Greenbelt : A regional developer.

If you are practicing this passage, here are the verified answers and explanations based on the text: Multiple Choice Questions (The site was disused from 1979 until a 1990 cleanup plan).
Derelict sites, often the remnants of former industrial activity, are characterized by soil degradation, low nutrient content, and the presence of pollutants such as heavy metals and hydrocarbons. These "brownfields" blight urban environments and pose health risks. The case study "Worms Put New Life into Derelict Site" highlights a paradigm shift in remediation: moving from heavy engineering solutions to biological solutions. This paper discusses the mechanisms by which worms facilitate site recovery, the limitations of the approach, and the broader implications for sustainable urban planning.

Good luck on your exam! Remember: The answer is often not in the first sentence you read, but in the subtle shift between “removing” and “changing.”
Researchers from Bell College of Technology found that earthworms are resilient even in hostile, contaminated environments. The worms revitalize the site through several key actions:
To score highly on this passage, you must understand why these answers are correct based on textual clues. Locating Keywords
Understanding how earthworms can restore damaged environments is a frequent topic in academic reading exams. This comprehensive guide provides the answers, detailed explanations, and a breakdown of the passage "Worms Put New Life Into Derelict Site." Direct Answer & Answer Key These trees perform a dual role: their roots
Certain resilient earthworm species can tolerate high levels of heavy metals. They absorb toxins like cadmium and lead into their bodily tissues, safely isolating the contaminants from the broader agricultural food chain while they are alive. Immobilization
While worms do not destroy heavy metals, their activity stimulates microbial growth. These microbes help bind or transform toxins into less bioavailable forms. Detailed Answer Explanations Why Question 1 is Paragraph E
