The principles of classic contaminated site management<\/strong><\/strong><\/h2>\n\n\n\n

Responsibility for the soil and the future<\/strong><\/strong><\/h3>\n\n\n\n

Soils are irreplaceable - they support our infrastructure, store water and form the basis of healthy ecosystems.
However, many areas in Germany are contaminated by historical use. The Treatment of contaminated sites<\/strong> is therefore one of the central tasks of contemporary engineering and environmental planning.<\/p>\n\n\n\n

The M&P Ingenieurgesellschaft Hannover - Member of the SIERA Alliance<\/strong> combines technical expertise with ecological responsibility. Our guiding principle:<\/p>\n\n\n\n

Engineering for a Better Tomorrow.<\/strong><\/p>\n\n\n\n

\n\n\n\n

What are suspected contaminated sites?<\/strong><\/strong><\/h3>\n\n\n\n

Numerous municipalities in Germany have derelict areas, which are referred to in technical jargon as Suspected contaminated sites<\/strong> are labelled. These are often former sand and gravel pits that were filled with unsorted waste after the Second World War until the 1970s - often known as \u201emayor dumps\u201c or \u201ewild dumps\u201c.<\/p>\n\n\n\n

These sites harbour risks for people and the environment and are now systematically investigated, assessed and, if necessary, remediated.<\/p>\n\n\n\n

\n\n\n\n

Legal basis<\/strong><\/strong><\/h3>\n\n\n\n

The legal basis is formed by the Federal Soil Protection Act (BBodSchG, 1998)<\/strong> and the Federal Soil Protection and Contaminated Sites Ordinance (BBodSchV, 2021)<\/strong>.
They regulate terms, obligations and limit values and provide the framework for a standardised nationwide approach.
This ensures that hazards are assessed transparently and remediation work is carried out in a legally compliant manner.<\/p>\n\n\n\n

This structured approach is the core of classic contaminated site management - scientifically sound, legally compliant and transparent.<\/p>\n\n\n\n

\n\n\n\n

Level 1 - Recording<\/strong><\/strong><\/h4>\n\n\n\n

This phase involves the systematic identification of all possible contaminated sites and old landfills.
M&P Nord Hannover analyses archives, commercial registers and historical aerial photographs. The result is an initial risk assessment and the creation of an area register.<\/p>\n\n\n\n

\n\n\n\n

Stage 2 - Individual case research and orientating investigation<\/strong><\/strong><\/h4>\n\n\n\n

Suspicious areas are analysed in more detail here:<\/p>\n\n\n\n

2a - Historical research:<\/strong> Analysis of previous uses, accidents and eyewitness accounts.
2b - Orienting investigation:<\/strong> Initial soil and groundwater samples confirm or refute the suspicion.<\/p>\n\n\n\n

This makes it possible to recognise at an early stage whether further investigations are necessary.<\/p>\n\n\n\n

\n\n\n\n

Stage 3 - Detailed investigation<\/strong><\/strong><\/h4>\n\n\n\n

The detailed analysis provides quantitative data on exposure.
M&P Nord uses targeted drilling and analytical methods to determine the spatial distribution of pollutants and assess their spread.
These results form the basis for remediation decisions and risk assessments.<\/p>\n\n\n\n

\n\n\n\n

Stage 4 - Remediation planning<\/strong><\/strong><\/h4>\n\n\n\n

If a risk is confirmed, a customised remediation concept is drawn up.
These include:<\/p>\n\n\n\n
