Expertise in Risk Management
Increasingly stringent governmental regulations, heightened public awareness, and
trends for conflict resolution by legal means demand proactive management of
occupational and environmental health issues. Common concerns include mold,
asbestos, lead manufacturing chemicals, industrial waste, and low-level, long-term
exposures in office environments.

NTH’s experienced staff, led by industrial hygienists, provides solutions to questions
about worker and building occupant exposures. We perform investigations to identify
potential health and compliance risks and develop plans for corrective actions. NTH
has performed numerous indoor air quality investigations for schools, governmental
agencies, and commercial building owners. We have also conducted investigations
and surveys for industrial facilities.
