Evaluatie van de in-situ behandeling van PFAS in het grondwater middels 6 pilootproeven
Taal: Nederlands
Kosten: gratis
In deze live webinar werd door Kris Maerten een reeks pilootproeven besproken die op één locatie zijn uitgevoerd door het bedrijf InSitu Remediation Services Ltd. Deze proeven werden uitgevoerd om verschillende technieken te evalueren voor de in situ behandeling van grondwater verontreinigd met PFAS (per- en polyfluorhoudende verontreinigingen).
De pilootproeven omvatten het gebruik van twee chemische oxidantia: waterstofperoxide en natriumpersulfaat, alsook vier adsorbentia: actieve kool in poedervorm (PAC), colloïdale actieve kool (CAC) (ons PlumeStop-product), ionenuitwisselingshars (REI) en biochar.
Voor de onderzochte locatie werden vóór de behandeling verschillende PFAS in het grondwater gedetecteerd, met name PFDS, PFBA, PFPeA, PFHxA, PFHpA, PFOA, PFOS en PFNA met concentraties tot 18.000 ng/L voor PFPeA. Daarnaast is er ook verontreiniging vastgesteld met benzine en met MTBE/TBA. Zes reactieve permeabele zones (PRZ’s) werden gecreëerd in een ondiepe watervoerende laag. De resultaten van dit werk zijn gepubliceerd in Wiley’s Remediation: https://doi.org/10.1002/rem.21653
In aanvulling hierop werd een stand van zaken gegeven van de ervaringen die REGENESIS heeft op andere PFAS sites en werden een aantal toekomstige projecten en lopende academische studies gepresenteerd (in samenwerking met 3 universiteiten). Na de presentatie kunt u uw vragen stellen in een vraag-en-antwoordsessie.
De belangrijkste punten die in dit webinar werden behandeld:
• De verdeling van de reagentia over het volledige injecie-interval wordt vergeleken. Dit laat zien dat CAC en persulfaat het meest gelijkmatig zijn verdeeld.
• De aanzienlijke hoeveelheden PAC en Biochar die in het filterpakket van peilbuizen terechtkomen en hoe dit de resultaten kan beïnvloeden.
• Chemische oxidatie lijkt niet effectief op PFAS.
• PAC’s, REI’s en Biochar laten aanvankelijke verlagingen van concentraties zien, gevolgd door een doorbraak van de verontreiniging.
• Alleen de CAC laat een langdurige efficiëntie zien waarbij alle PFAS onder detectielimiet blijven tot minstens 550 dagen na toepassing.

Études de cas sur la gestion rapide de panaches d’hydrocarbures et meilleures pratiques de dimensionnement
Langue: français
Accès: gratuit
Intervenants: Mariangela Donati, Aurélien Triger et Kris Maerten
L’application des technologies d’adsorption et de stimulation in-situ pour traiter les panaches de polluants organiques dans les nappes complète la panoplie des nombreuses solutions de gestion disponibles pour la remise en état des sites.
Dans ce webinaire, nous exposons les meilleures pratiques en matière de conception et d’application de cette technique, en nous appuyant sur une série d’études de cas tirées des références d’Antea Group sur des sites pollués par des hydrocarbures et où l’utilisation du fluide PetroFix a permis de finaliser la remédiation sur site.
Ce charbon actif colloïdal à double fonction, PetroFix, s’est fait une place de choix dans les injections en maillages, en barrières, et comme amendement appliqué en fond de fouille en vue d’un traitement poussé des sites pollués par des hydrocarbures pétroliers. La mise en œuvre de la technologie est simple, la taille des particules est idéale pour maximiser l’adsorption des hydrocarbures dissous, et le mélange d’accepteurs d’électrons stimule la biodégradation.
Trois études de cas sont présentées, portant sur les techniques d’application, les modifications de la chimie du site, les profils bactériens, et les enseignements tirés.
Les études de cas présentées dans ce webinaire comprennent :
- Un traitement combinant excavation et application de PetroFix sur le site d’un commerce de proximité, qui a permis de finaliser la remédiation du site.
- Un site complexe où le traitement des nombreux composés présents dans la nappe a été entrepris depuis plus de vingt ans et où PetroFix améliore désormais l’efficacité des travaux de dépollution.
- Un site présentant de faibles concentrations de BTEX, où l’injection de PetroFix en maillage a assuré un traitement poussé jusqu’à l’atteinte des objectifs de la remédiation.
Ce webinaire met également en avant les meilleures pratiques pour la conception et la mise en œuvre des travaux utilisant PetroFix, de façon à garantir des résultats concluants dans la dépollution.

Webinarium: Pågående in situ-sanering på Hagalunds depån, Nordeuropas största tågdepå
Språk: Svenska
Presentatör: Say Svanström, Envytech Solutions AB
EnvyTech Solutions AB har fått i uppdrag av Jernhusen Verkstäder AB att utföra en in situ-sanering inom Hagalunds depå i Solna, Nordens största tågdepå. In situ-saneringen utförs för att möjliggöra framtida utveckling och förvaltning av fastigheten.
Depån har en lång historik av järnvägsrelaterad verksamhet och inom fastigheten har underhåll av ång-, el- och diesellok hanterats samt förvaring av diesel, spillolja och kol.
Inför in-situ saneringen utförde ett omfattande förutsättningskontroll, detta för att kunna avgränsa påträffad förorening i djup och plan samt för att kunna ta fram en platsanpassad design. Vid förundersökningen utfördes även ett injekteringstestet för att optimera designen för de aktuella förhållandena.
In situ-saneringen innefattade en kombination av olika in situ-saneringsmetoder. För att avlägsna fri fas petroleumprodukter användes vakuumextraktion och för att bryta ner petroleumföroreningen i jord och grundvatten direktinjekterades oxidations- och biostimulerande medel i marken. För att även förhindra återkontaminering i redan sanerade områden installerades horisontella och vertikala barriärer med aktivt kol.
För att utreda in-situ metodernas effekt utförs nu ett kontrollprogram.

Presentato da: Ing. Mariangela Donati, Mediterranean District Manager
In questo secondo webinar della nostra serie “Nuove opzioni di trattamento per i siti contaminati da idrocarburi”, osserviamo più da vicino come PetroFix viene utilizzato per realizzare barriere reattive permeabili iniettabili (I-PRB). Questa strategia di bonifica viene utilizzata per prevenire la migrazione di contaminanti all’esterno del sito in aree industriali dismesse, aree in fase di ri-conversione e costruzione e siti industriali attivi. In tutta Europa, ad oggi è stato installato oltre un chilometro di I-PRB utilizzando PetroFix. Mariangela Donati illustra perché le società ambientali e quelle di costruzioni trovano particolare interesse nel sostituire opere di contenimento fisico o altri interventi complessi con questo semplice approccio.
Punti chiave che sono approfonditi in questo webinar:
- In che modo le I-PRB con PetroFix riducono la responsabilità off-site
- Le attività di indagine sul sito utili per installare una I-PRB efficace
- Metodi di iniezione e installazione
- Vantaggi dell’uso delle I-PRB sui costi e sul cronoprogramma dei lavori
- Esempi di installazioni in situ
Alla fine del webinar è presente un’ampia sessione Q&A (domande e risposte) in cui viene data risposta alle domande poste dai partecipanti.

Expediting vapour intrusion pathway assessments & solutions, using high resolution continuous monitoring of VOCs
Duration: 1h
Language: English
REGENESIS is pleased to announce a special vapour intrusion webinar with guest speakers Blayne Hartman of Hartman Environmental Geoscience (USA) and Tom Wuyts, team manager at Terra Engineering & Consultancy, part of Group Van Vooren NV (Belgium). In this live European webinar, Blayne and Tom discuss the challenges of vapour intrusion assessments and the benefits of continuous monitoring. They are joined by Rick Gillespie, Senior Vice President of Land Science, the vapour mitigation division of REGENESIS.
With vapour intrusion assessments, typically only a few contaminant concentration measurements are made, so it is often difficult to reach a conclusion if the vapour intrusion pathway is a concern. The result is that vapour intrusion investigations can drag on for months to years before a conclusion can be reached regarding the potential risk. Such time periods are unacceptable if there is a potential risk to human health.
In this webinar you will learn:
- What is a continuous monitoring system and what does it consists of?
- The benefits of continuous monitoring:
- Large volume of contaminant concentration data over time for instant recognition of temporal and spatial patterns
- Combined benefits from simultaneous pressure and climatic data
- Rapid determination of cause and effect of measured VOC concentrations (<weeks), enabling remedies to be rapidly employed
- Case study examples from a variety of sites, illustrating the effectiveness of high-resolution data for expediting vapour intrusion assessments.
- Lessons learned from these sites, on:
- Temporal and spatial variability of indoor air concentrations
- Factors influencing contaminant concentrations
- Immediate mitigation remedies
