AHERA : Un outil essentiel pour la protection de l'eau et de l'environnement
La Loi sur la réaction aux situations d'urgence liées à l'amiante (AHERA), promulguée en 1986, est une loi cruciale qui joue un rôle important dans la protection de la santé publique et de l'environnement, en particulier dans le domaine du traitement des eaux.
Comprendre l'impact d'AHERA sur l'environnement et le traitement des eaux :
AHERA se concentre sur l'identification, la gestion et le contrôle de l'amiante dans les écoles, mais ses principes s'étendent au-delà des institutions éducatives. Voici comment elle s'articule avec l'environnement et le traitement des eaux :
- L'amiante dans les infrastructures d'eau : L'amiante a été largement utilisé dans les usines de traitement des eaux et les systèmes de distribution, y compris les tuyaux, les réservoirs et les filtres. L'accent mis par AHERA sur l'identification et la gestion des risques liés à l'amiante souligne l'importance d'inspecter et de traiter l'amiante dans ces composants critiques de l'infrastructure.
- Prévenir la contamination : Les fibres d'amiante sont connues pour être cancérigènes. Si elles sont perturbées ou libérées dans l'approvisionnement en eau, elles représentent une menace importante pour la santé publique. Les directives d'AHERA pour la gestion de l'amiante contribuent à prévenir cette contamination.
- Protection des travailleurs du traitement des eaux : Les réglementations d'AHERA sur la protection contre l'exposition à l'amiante s'appliquent aux travailleurs impliqués dans les opérations de traitement des eaux. Cela garantit que ceux qui sont responsables de la maintenance et de la mise à niveau des infrastructures d'eau sont à l'abri des fibres d'amiante nocives.
- Développer des stratégies d'atténuation : AHERA exige le développement de plans de gestion de l'amiante pour les écoles. Ces plans fournissent des cadres précieux pour les installations de traitement des eaux afin de créer leurs propres stratégies complètes pour identifier, atténuer et gérer les risques liés à l'amiante.
- Promouvoir la sensibilisation : AHERA a joué un rôle clé dans la sensibilisation aux dangers de l'amiante. Cette sensibilisation accrue a conduit à de meilleures pratiques et à des environnements de travail plus sûrs dans l'industrie du traitement des eaux.
AHERA et l'avenir du traitement des eaux :
Alors que notre compréhension des risques pour la santé associés à l'amiante continue d'évoluer, il est essentiel d'adapter et d'améliorer les principes énoncés par AHERA.
Voici ce que l'avenir réserve :
- Accentuation accrue sur la prévention : L'accent devrait être mis sur la prévention de la libération de fibres d'amiante provenant des infrastructures existantes. Cela peut impliquer l'utilisation de matériaux alternatifs lors des mises à niveau ou la priorité à la suppression de l'amiante dans les zones sensibles.
- Inspection et tests améliorés : Des inspections régulières et des méthodes de test avancées seront essentielles pour identifier de manière proactive les dangers potentiels liés à l'amiante dans les installations de traitement des eaux.
- Formation et éducation : Les professionnels du traitement des eaux ont besoin d'une formation et d'une éducation solides sur l'identification, la gestion et l'atténuation des risques liés à l'amiante.
- Collaboration et partage d'informations : La collaboration entre les organismes de réglementation, les parties prenantes de l'industrie et les institutions de recherche est essentielle pour élaborer les meilleures pratiques et mettre en œuvre des stratégies efficaces de gestion de l'amiante.
L'héritage d'AHERA s'étend bien au-delà des écoles. En mettant en œuvre ses principes et en les adaptant aux besoins en constante évolution de l'industrie du traitement des eaux, nous pouvons protéger la santé publique et garantir un approvisionnement en eau sûr et propre pour les générations à venir.

Techniques
Chapter 1: Techniques for Asbestos Management in Water Treatment
This chapter delves into the specific techniques used to manage asbestos in water treatment facilities, drawing upon the principles of AHERA.
1.1 Asbestos Identification and Assessment:
- Visual Inspection: Trained personnel visually inspect water treatment facilities for potential asbestos-containing materials (ACMs). This includes pipes, tanks, filters, insulation, and other infrastructure components.
- Bulk Sampling and Analysis: Suspected ACMs are collected and sent to accredited laboratories for analysis using polarized light microscopy (PLM) or transmission electron microscopy (TEM).
- Air Sampling: Air samples are collected to determine the presence and concentration of airborne asbestos fibers, especially during maintenance or repair activities.
- Asbestos Management Plan: Based on the assessment results, a comprehensive asbestos management plan is developed, outlining procedures for handling and managing ACMs.
1.2 Asbestos Removal and Encapsulation:
- Removal: If ACMs pose a significant risk, they are removed by trained and certified professionals using specialized techniques and protective equipment.
- Encapsulation: ACMs are sealed with encapsulating materials to prevent fiber release. Encapsulation is typically applied to asbestos-containing insulation or coatings.
- Enclosure: ACMs can be enclosed in secure structures like barriers or walls to restrict access and prevent fiber release.
1.3 Asbestos Control Measures:
- Personal Protective Equipment (PPE): Workers handling ACMs must wear appropriate PPE, including respirators, gloves, and coveralls.
- Wet Methods: Water is used during removal and repair activities to minimize dust generation and the release of asbestos fibers.
- Negative Pressure Enclosures: Enclosures with negative air pressure prevent contaminated air from escaping into the surrounding environment.
- Proper Waste Disposal: Removed ACMs must be disposed of in accordance with local and federal regulations, usually at certified asbestos waste disposal sites.
1.4 Ongoing Monitoring and Maintenance:
- Regular Inspections: Water treatment facilities must undergo regular inspections to ensure the effectiveness of asbestos management measures and identify any potential problems.
- Maintenance and Repair: Any repairs or modifications to ACMs must be conducted by trained professionals using proper techniques to avoid fiber release.
- Employee Training: All personnel working at water treatment facilities must receive ongoing training on asbestos identification, handling, and safety procedures.
