Comprehensive Source Water Quality Management Support

Our staff has expertise on a broad range of environmental issues. We understand environmental challenges and their relationship to resource use, water treatment, regulatory compliance, hazard mitigation and investigation of emerging issues.

Reservoir Water Quality Management

Southeast Morris County Municipal Utilities Authorities (SMCMUA), NJ: Clyde Potts Water Quality Management Program

Harmful algal blooms (HABs) are emerging across the country and many water utilities are seeking tools to help better manage issues caused by HABs. In addition to taste-and-odor and cyanotoxins, HABs can impact other finished water quality parameters such as increased total organic carbon (TOC) that can result in the formation of disinfection by-products (DBPs), dissolved oxygen depletion, and changes in treated water pH and alkalinity. Recently Southeast Morris County Municipal Utility Authority (SMCMUA) has experienced more frequent HABs in their Clyde Potts Reservoir (Reservoir) that serves as the source for their Clyde Potts Water Treatment Plant (CPWTP). The utility engaged the team led by Corona to help provide a better understanding of water quality conditions that would result in increased cyanobacteria blooms in the Reservoir, and to identify mitigation of HABs in the Reservoir and the CPWTP, such that the treated water would consistently achieve desired water quality targets. The Corona team developed a comprehensive plan for monitoring of HABs and indicators, with a goal of identifying trigger conditions that would result in operational changes during HAB events. The project also identified numerous near-term and long-term infrastructure improvements in the Reservoir and at the CPWTP that will optimize operations and result in improved treated water quality.

Source Water Assessment and Protection

Metropolitan Washington Council of Governments, D.C.: Potential PFAS Source Identification

In response to growing awareness about the potential hazards of perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), and other per- and polyfluoroalkyl substances (PFAS) for drinking water sources, Corona developed a methodology to map likely sources of PFAS near surface and groundwater sources. This methodology uses a variety of federal, state, and local datasets as well as NAICS and SIC code information to target potential source facilities based on historically high-risk industries. It was first applied in the watersheds utilized by the drinking water utility members of the Metropolitan Washington Council of Governments (MWCOG). The resulting inventory, which will continue to be expanded and refined, may be used to identify potential sources in the event that one or more PFAS are detected in raw water samples and can help guide source water risk assessment, cost recovery and mitigation efforts.

Emergency Response Planning

Middlesex Water Company, NJ: Spill Response Drill and Ongoing Emergency Support

Corona has pioneered several of its emergency response planning services through its partnership with New Jersey-based water utility Middlesex Water Company (MWC). In 2018, Corona helped design a spill response drill that allowed MWC to test their emergency response plan and data management systems in response to an acute source water contamination event. The drill was designed using information  acquired about MWC’s source water in 2017 in order to provide drill participants with a realistic hypothetical scenario. The drill was attended by a diverse group of participants from the utility’s various departments, as well as representatives from local water management and regulatory agencies, and helped highlight opportunities for MWC to improve their emergency response capabilities and strengthen advantageous partnerships. Also, in 2018 Corona set up an emergency response hotline to provide MWC with analytical support during acute source water contamination incidents.

Environmental Information Systems

WaterSuite: Integrated Water Data Management

The Corona Environmental Consulting team has extensive experience in the design, implementation and maintenance of environmental information systems. We have successfully developed a cloud-based system that captures, processes and analyzes complex environmental data for the water community and continue to adapt this system to the specific needs of our clients, data management, prioritization, monitoring, and reporting capabilities for source water protection and emergency planning.

Making Better Decisions Starts With Better Data Management

Whether you are looking for an effective way to conduct your source water protection program or a centralized system to manage your water quality data, WaterSuite provides a flexible platform to meet your organization’s needs.
