Environment Authority is an Authority Network America reference resource that organizes environmental specialty services into a structured guide for property owners, facility managers, legal counsel, and environmental professionals. It covers approximately 30 service categories with distinct regulatory, technical, or professional requirements, helping readers understand the scope of specialist work and navigate relevant topics. Its coverage ranges from Phase I and Phase II Environmental Site Assessments, asbestos inspection and abatement, and lead paint testing and removal to ecological restoration, brownfield redevelopment, and environmental remediation.

Other topics include air and indoor air quality testing, environmental laboratory testing and monitoring, groundwater and soil assessment, hazardous waste management, industrial hygiene, radon mitigation, spill response, stormwater management, underground storage tanks, vapor intrusion, and wetlands permitting. The resource also addresses hiring environmental firms, provider qualifications, costs, property-specific services, licensing, certifications, EPA oversight, and federal regulations, including OSHA standards. It explains that service categories are evaluated against regulatory anchors and technical distinctions, rather than through commercial referrals
