Environmental challenges are rarely straightforward. They can be costly, complex, and legally demanding—often involving multiple or unidentified responsible parties. NWS brings clarity to this complexity through advanced environmental forensics that pinpoint contaminant origins and migration patterns.
By integrating qualitative insight, quantitative rigor, and statistical analysis with powerful data visualization, NWS transforms dense technical data into clear, defensible conclusions. This approach not only strengthens the scientific basis of each investigation but also ensures more targeted, efficient, and cost-effective solutions. NWS has in depth knowledge and experience with forensics, multi-party site management, and can support your legal team even in the most challenging of sites.

NWS delivers strong project and program management built on clear communication, data-driven tracking, and accountability. Using customized tools and metrics, we monitor deliverables, budgets, and performance indicators to ensure on-time, on-budget outcomes.

Our approach moves clients from reactive compliance to proactive planning and advocacy, combining technical rigor with forward-thinking strategy and efficiency.
