Site of National Interest (SIN), Napoli, Campania, Italy

Bagnoli-Coroglio (Naples)

Former Ilva/Italsider steelworks and Eternit plant in western Naples, on the Gulf of Pozzuoli, closed in 1990-1991. Soils hold PAHs, heavy hydrocarbons, PCBs and metals; the seabed in front is contaminated too.

Contaminants

Status

Remediation under way

Remediation and urban regeneration are entrusted to a Government Special Commissioner, with Invitalia as implementing body. The Programme Agreement of 3 March 2020 allocates 387,237,826 euro (MASE fact sheet, 2021). No up-to-date official percentage of remediated area was found.

Story

The first industrial activity at Bagnoli dates from 1853; the turning point came in 1905, when construction of the Ilva steelworks began. In 1936-1938 the Eternit plant was built next to it. Between 1986 and 1990 production was scaled down: Eternit was closed, Ilva's hot area shut in 1990 and in 1991 the works ceased all activity.

In topsoil the most widespread exceedances are for zinc, lead and tin and, to a lesser extent, arsenic, mercury and copper; among organics, PAHs, heavy hydrocarbons and PCBs occur across the whole site. Deep soil shows a similar picture, with chromium, copper, zinc and lead. Groundwater holds PAHs, hydrocarbons, iron, manganese and occasionally nickel.

The site has been a SIN since 2000 (law 388/2000); its perimeter was set in 2001 and again in 2014. A new Special Commissioner has been in office since 2018; in 2020 a Programme Agreement allocated about 387 million euro for containment, remediation and urban redevelopment.

Plants and fungi at this site

PhytoremediationField pilot

Festuca sp.

Zuzolo, Guarino, Sciarrillo and colleagues set up in-field mesocosms with soil from the site, comparing native species grown singly and in mixture and studying soil, microbiome and plant gene expression.

Outcome The mixed stand did better both in phytostabilisation efficiency and in stress tolerance. Among the species fescue performed best. The abstract does not say by how much soil concentrations fell.
