SARA : Une pierre angulaire de la protection de l'environnement dans le traitement des eaux
La Loi sur les amendements et la réautorisation du Superfund (SARA), adoptée en 1986, est une loi phare qui a eu un impact significatif sur le domaine de l'environnement et du traitement des eaux. Alors que la Loi initiale sur le Superfund (CERCLA) se concentrait sur le nettoyage des sites d'enfouissement de déchets dangereux existants, SARA a élargi la portée et renforcé les outils disponibles pour la protection de l'environnement.
Dispositions clés de SARA dans le domaine de l'environnement et du traitement des eaux :
- Droit de savoir de la communauté : Cette section oblige les entreprises à déclarer les types et les quantités de produits chimiques dangereux qu'elles utilisent, stockent et rejettent. Ces informations sont mises à la disposition du public, permettant aux communautés de comprendre les risques environnementaux potentiels et de défendre leur santé.
- Planification d'urgence et droit de savoir de la communauté (EPCRA) : Cette section exige des installations qu'elles élaborent et mettent en œuvre des plans d'urgence en cas de rejets accidentels de substances dangereuses. Elle oblige également à déclarer les rejets, permettant une réponse et une atténuation rapides.
- Inventaire des rejets toxiques (TRI) : SARA a mis en place le TRI, une base de données accessible au public qui suit le rejet de certains produits chimiques toxiques provenant d'installations industrielles. Ces données permettent d'identifier les points chauds de pollution, d'informer les décisions réglementaires et d'encourager les industries à réduire leur impact environnemental.
- Gestion des déchets dangereux : SARA a renforcé les exigences en matière de gestion des déchets dangereux, notamment des réglementations plus strictes pour le stockage, le transport et l'élimination. Ceci est crucial pour prévenir la contamination des sources d'eau et protéger la santé publique.
- Nettoyage du Superfund : SARA a élargi le programme Superfund pour inclure le nettoyage des sites d'enfouissement de déchets dangereux abandonnés, fournissant des fonds et des orientations pour les efforts de remédiation. Cela comprend la prise en charge des sources d'eau contaminées et la mise en œuvre de solutions de traitement des eaux.
Impact sur le traitement des eaux :
SARA a considérablement influencé les pratiques de traitement des eaux en :
- Favorisant la prévention : Les exigences de déclaration et la responsabilité potentielle en vertu de SARA ont incité les industries à minimiser leurs rejets de produits chimiques dangereux, réduisant ainsi la charge globale sur les installations de traitement des eaux.
- Améliorant la technologie de traitement : La nécessité de traiter les sources d'eau contaminées résultant des sites du Superfund a stimulé le développement et l'amélioration des technologies de traitement des eaux, conduisant à des solutions plus efficaces et plus performantes.

This has spurred the development of more sensitive and accurate analytical methods for detecting and quantifying contaminants in water. Real-time monitoring and early warning systems are becoming more common.
- Source Control Techniques: By emphasizing prevention and holding industries accountable for their releases, SARA indirectly encourages the implementation of source control techniques to prevent contamination from ever reaching water sources. This includes better waste management practices, improved process control in industries, and the adoption of cleaner technologies.
Chapter 2: Models
SARA doesn't prescribe specific models for water treatment management, but its provisions have influenced the development and application of various models used in environmental risk assessment and management. These include:
- Risk Assessment Models: The act's emphasis on understanding and managing risks associated with hazardous substances has led to the development and refinement of risk assessment models for evaluating the potential impact of contaminated sites on water resources. These models incorporate factors such as contaminant concentration, transport pathways, and exposure routes to estimate human and ecological risks.
- Environmental Impact Assessment (EIA) Models: SARA requires EIAs for many projects that could potentially impact water quality. These assessments often utilize models to predict the environmental consequences of proposed activities and to evaluate the effectiveness of proposed mitigation measures.
- Decision Support Systems (DSS): The complexity of managing contaminated sites and implementing effective water treatment strategies has spurred the development of DSS. These systems integrate various data sources, models, and tools to help decision-makers evaluate different options and make informed choices.
Chapter 3: Software
