Natural Environment


Cadmus supports clients in the natural environment market with focuses on corporate governance and strategy, international development, and water.




Corporate Governance and Strategy

Cadmus’ governance and strategy experts provide advice and other services to commercial clients, government agencies, and other organizations, especially as they navigate profound environmental, health, and safety (EHS) shifts.

Our experts guide clients in enhancing the management of compliance programs, risk issues, and corporate social responsibility/sustainability portfolios. These professionals are regarded as strategists, problem solvers, and thought leaders. Their broad experience encompasses assignments within most industrial sectors and in many countries around the world.

International Development

Cadmus provides international support in capacity building, policy development, and operational assessment and evaluation to help host governments, the United States Agency for International Development (USAID), and private sector clients achieve economic development goals through sustainable practices that are consistent with environmental health and safety standards.

We field teams of international consultants to identify and recommend actions addressing environmental issues associated with agricultural development, energy resources, and transportation.

We routinely review proposed private sector projects and ongoing operations to develop recommendations for improving the organizational management of environment, safety, and employee health, and the links between environmental and social performance goals.


As a major support contractor with the U.S. EPA’s Office of Water, Cadmus has worked on every major drinking water rule developed since 1983 to implement the Safe Drinking Water Act (SDWA) and its amendments. Besides providing support for EPA’s rule development, we have prepared training materials, held workshops, and conducted training sessions across the country on the implementation of more than 15 SDWA regulations and a suite of surface water treatment rules.

We currently provide a wide range of support for EPA’s implementation of existing drinking water rules and the development of new ones:

  • We are aiding the Agency’s implementation of the Long Term 2 Enhanced Surface Water Treatment Rule (LT2), the Stage 2 Disinfection Byproducts Rule (Stage 2 DBP), and the Ground Water Treatment Rule by developing training materials and guidance manuals. And, in the case of LT2, we are supporting the data system that will maintain the results of sampling by surface water systems for the biological contaminants cryptosporidium, e. coli, or both.
  • We are supporting EPA’s implementation of the Lead and Copper Rule (LCR) and the development and, later, the implementation of the short- and long-term revisions to the 20-year-old rule.
  • As EPA develops the Total Coliform-Distribution System Rule, we are performing a wide range of regulatory development support functions. And once the new rule is in place, we will aid EPA’s implementation of it.
  • We have worked for a number of years on EPA’s multistage Contaminant Candidate List (CCL) classification process. Now we are supporting EPA’s development of rules to regulate emerging contaminants such as perchlorate.

Cadmus also provides training on and conducts sanitary surveys, comprehensive performance evaluations (CPEs), and vulnerability assessments.

Small systems issues are of particular concern and we have a number of self-assessment tools and manuals to assist states and water systems with technical, managerial, and financial capacity issues. As EPA seeks to re-energize its capacity development work, Cadmus is providing support to the four workgroups recently formed to identify best practices for improving the capacity of small systems.

We collect data on drinking water programs from surveys we develop and execute in order to give government decision-makers the information they need to make sound choices. Among the major surveys we undertake for the EPA Office of Ground Water and Drinking Water are the Drinking Water Infrastructure Needs Survey and Assessment (every 4 years) and the Community Water System Survey (every 5 years).

Drinking water has been a core Cadmus business since our founding in 1983. Our capabilities to serve this vital market are unmatched in the consulting industry.

Cadmus supports clients in the areas of:

  • Drinking Water Program Implementation through training, public education and outreach, data transfer support, and national and state program implementation support.
  • Drinking Water Standards, Risk Management, and Risk Communication through our work on contaminant occurrence, fate, and transport; EPA’s Contaminant Candidate List and Six-Year Drinking Water Review process; and the tools we have developed to communicate health and environmental risks of numerous drinking water contaminants.
  • Source Water Protection through assessments, development of technical guidance documents, training, and the conduct of workshops and conferences.
  • Underground Injection Control through work on large-capacity septic systems, drinking water treatment residuals, and geologic sequestration of carbon dioxide.
  • Watershed Science and Management through water quality assessments, TMDL development, and wetland assessment.
  • Research and Development through scientific, technical, research, engineering, and modeling support for EPA’s Office of Research and Development.
  • Drinking Water Analytics through services for utilities such as demand forecasting, financial planning, water conservation program design, cost-of-service studies, and rate structure analysis.
