We are water resource specialists

Where do you turn for technical expertise when you’re charged with protecting and restoring our nation’s valuable water resources? You turn to the team whose singular business focus is providing that support to state and federal agencies.

At PG, we’re personally and professionally committed to providing high-quality support across the water sector to yield improvements in the environment and public health. And we have a track record—and a long list of satisfied clients—to back that up.

We offer professional services in

  • NPDES Permitting

    Whether you work at the national, state, or tribal level, PG’s permitting experts can help optimize your National Pollutant Discharge Elimination System (NPDES) permitting process to reduce permit backlogs and help ensure timely permit issuance.

  • Compliance

    PG’s credentialed inspectors have inspected hundreds of facilities, systems, and programs across the country. These have included combined and separate sanitary sewer systems, construction sites and industrial facilities, municipal separate storm sewer systems (MS4), industrial pretreatment programs (IPP) and industrial users, and combined animal feeding operations (CAFO)—not to mention countless major and minor NPDES dischargers. From routine compliance inspections to diagnostic audits, PG stands ready to support your compliance program needs.

  • Ecological Services

    Gauging the health of our nation’s surface waters requires a diverse set of skills. PG scientists are intimately familiar with the tools and approaches to conducting water quality and ecological assessments in U.S. waters and habitats. Our team has surveyed the health of diverse aquatic systems across the country, conducted wetland delineations, jurisdictional water investigations, and developed and implemented protocols to sample and measure water quality, sediment, fish species, macroinvertebrates, and habitat in all types of ambient waters across the U.S. PG’s team also supports agencies in acquiring and/or managing laboratory support to analyze the fields samples, and then statistically analyze the resulting field data. No matter how small or large your project, our team can assist.

  • Enforcement

    With decades of real-world experience and extensive, detailed knowledge of water quality programs and their regulated communities, PG’s senior professionals are uniquely qualified to support Clean Water Act (CWA) enforcement efforts. That’s why, for a variety of complex and nationally significant cases, the U.S. EPA and the Department of Justice have frequently accessed our team to build cases, serve as expert witnesses, and support negotiations and settlement discussions. Whether you need coordinated, cross-cutting services, or expert input in specific areas such as water quality infrastructure analysis/cost estimation, field work to gather data, or monitoring or modelling to quantify water quality impacts, PG’s highly seasoned team can help.

  • Training

    Building internal capacities, knowledge, and skills—in both new and experienced agency staff—has been a key strategy for many of PG’s federal and state customers. We offer a wide range of training and knowledge transfer services to support these initiatives. For example, we design and deliver training for NPDES inspectors and permit writers; provide expert advice and curriculum development support to agencies developing in-house training programs; and create guidance and tools to support water quality professionals in doing their jobs. Whatever your need, from classroom training to webinars to field instruction and educational tool development, our team stands ready to help your team grow.

  • Regulatory & Policy Analysis

    Successful implementation of CWA programs depends on expert knowledge, assessment, and analysis to support sound regulatory and policy decision-making. For over 10 years, PG’s team has helped the U.S. EPA and states build, evolve, and refine the basis for CWA implementation. We have evaluated treatment technologies and conducted cost-benefit/regulatory impact analyses; supported development of national technology-based effluent limitations, guidelines, and standards; developed TMDL implementation tools; assessed climate change impacts; and much more. When your program needs to revise or make new policy or regulatory decisions, PG’s team stands ready to provide the expert input and analytical basis to support this work.
