Subordinate lithologies include ash layers, dolomitized horizons, and siliceous beds. We distinguished five lithological units: (1) a gray marl unit lacking major phosphate accumulations (Ͼ 16.3 Ma; average TOC content 2% by weight; average sedimentation rate 75 m/My; average TOC accumulation rate 0.19 mg/cm 2 /yr); (2) a black marl unit including lightcolored phosphatic laminae, lenses, and discrete particles (16.3-14.5 Ma; average TOC content 7.5% by weight; average sedimentation rate 20 m/My; average TOC accumulation rate 0.19 mg/cm 2 /yr); (3) a red marl unit including light-colored phosphatic laminae, lenses, and commonly reworked particles (14.5-12.7 Ma; average TOC content 15% by weight; average sedimentation rate 20 m/My (14.5-13.3 Ma) and 2 m/My (13.3-12.7 Ma), respectively; average TOC accumulation rate 0.39 mg/cm 2 /yr (14.5-13.3 Ma) and 0.04 mg/cm 2 /yr (13.3-12.7 Ma), respectively); (4) a unit of complex and condensed phosphatic beds, interbedded with red marl (12.7-10.8 Ma; average sedimentation rate 3 m/My); and (5) a black marl unit with intercalated phosphatic laminae and lenses (Ͻ 10.8 Ma; average sedimentation rate 9 m/My; average TOC accumulation rate 0.09 mg/cm 2 /yr).

Minor lithologies include volcanic ash, dolomite, porcelanite and chert, and condensed phosphatic beds. Sediments dated as 14.3-13.5 Ma have average total organic carbon (TOC) values around 8.5 wt%, and organic carbon (OC) accumulation rates are around 565 mg/cm 2 /k.y. Sediments dated as 13.5-13 Ma are characterized by average TOC values of 12.6 wt% and OC accumulation rates of around 1130 mg/cm 2 / k.y. The interval between 13 and 10.6 Ma is marked by condensation; average TOC values are around 8.6 wt%, and OC accumulation rates diminished to around 55 mg/cm 2 /k.y. The last interval studied is dated as 10.6-9.4 Ma, and average TOC values are around 6 wt%, whereas OC accumulation rates rose again to 320 mg/cm 2 /k.y.

Decision makers, scientists, businesses and individual citizens generally accept and understand the impacts of air and water pollution on human health and environment, but the impacts of soil contamination have a much lower profile. Soil contamination is very often perceived as a burden for policy makers and public administration and as a potential threat for citizens’ health and environment. From the 1980s until today Europe has developed numerous laws to reduce and remediate the adverse effects of soil pollution. Each country has gathered very valuable information and published their own work in the national language (normally not accessible and not known by other countries in Europe), on how to manage contaminated sites that originated from industrial settlements, urbanization or by accidents.
This document is published at the initiative of the Eionet National Reference Centres for Soil, which established in 2015 an ad-hoc working group on contaminated sites and brownfields in Europe.The objective was to collect cases and successful stories of remediated sites and brownfields, harmonise and facilitate exchanges of information on contaminated soils and soil remediation between the Eionet contributing countries. These stories have been compiled in the present report as a publication to the International Year of Soil 2015. It aims to contribute to a better understanding of the remediation of contaminated sites and brownfields rehabilitation which is essential for sustainable land use management and to share best practices and new techniques in soil remediation and management of contaminated sites, meanwhile raising awareness of the enormous efforts needed to succeed. This document presents examples of success stories of remediation of contaminated soils in various contexts and different European countries. It is not meant to provide an exhaustive inventory of remediated sites in all countries. Thirteen countries comprising 19 European regions present a total of 29 cases which illustrate how soil and brownfields remediation along with sustainable land management have become essential for reversing the trend of soil degradation and ensuring the provision of ecosystem services by soil. The cases show progress in research and innovative technologies of soil remediation, new outstanding approaches to soil remediation management, beneficial integration of stakeholders in decision-making and fruitful progress in raising public awareness and citizen science.These success stories have also achieved the restoration, safeguarding and longterm ensurance of some of the most widely recognized functions of soils, such as support for water regulation and purification, provision of new habitat for organisms, food, fibre and fuel, promotion of cultural and recreation areas and foundation for human infrastructure.
