Integrating volunteer monitoring data to protect Long Island Sound.

Water quality monitoring efforts across Long Island Sound have long been decentralized as community groups and institutions collect valuable data using different methods, formats, and reporting practices. Grassroots programs generate critical local insights, but the lack of standardization and centralization limited the ability to aggregate, validate, and analyze data at a regional scale.

Stakeholders — including researchers, educators, and public agencies — faced barriers in accessing and comparing datasets, while volunteers encountered technical challenges in contributing to regional and national reporting systems. The silos constrained community science from supporting regulatory compliance, public health, and ecosystem management.

Key Challenges:

• Standardize water quality data structures, metadata, and reporting workflows across multiple organizations and formats into a unified platform
• Enable validation and quality assurance of diverse datasets
• Provide accessible tools for visualization and analysis
• Facilitate regional collaboration among community scientists, researchers, and regulatory agencies
• Submit information to the U.S. EPA Water Quality Exchange (WQX)

Save the Sound partnered with KISTERS to custom develop QuickDrops, a cloud-based community data platform (CDP) designed for the storage, integration, analysis, and publication of water quality data across Long Island Sound. The platform provides a standardized, user-friendly web interface that welcomes free participation from volunteer monitoring organizations. The platform enables contributors, both technical and non-technical users, to upload new and historical datasets, apply data validation processes, and publish validated data for broader use.

Developed through an agile, collaborative process, the platform overcomes accessibility, data standardization, and quality assurance obstacles while supporting integration with the national water quality reporting framework.

Key Technical Specifications:

• User and account management supporting contributors, researchers, and public users
• Standardized workflows for uploading continuous and non-continuous / discrete  datasets, including drag-and-drop ingestion and automated file format recognition
• Tools for manual data transformation to align with U.S. EPA WQX data standards
• Integrated QA/QC processes, including support for metadata, quality assurance project plans (QAPP), and standard operating procedures (SOP) documentation
• Interactive data visualization tools enabling spatial and temporal analysis of parameters
  such as temperature, salinity, dissolved oxygen, nutrients, and bacteria
• Map-based data retrieval and filtering capabilities for targeted analysis
• One-click data submission to the U.S. EPA Water Quality Exchange (WQX), with guided onboarding for new users

QuickDrops has empowered Save the Sound and its partners to unify fragmented community monitoring into a coordinated, data-driven regional resource. By centralizing and standardizing datasets, the platform improves data accessibility, consistency and usability across groups who want to sustain the waters off the New York and Connecticut coast.

Volunteer water quality monitors contribute new and historical data, so water management decisions take into account previously inaccessible datasets. Automated processes lower technical barriers, making community science more inclusive to the region as well as the nation.

Researchers and educators unlock integrated visualization and analytical tools that support the analysis and interpretation of water quality trends. The ability to examine spatial and temporal trends across multiple parameters enhances communication of complex ecosystem dynamics with students, policymakers, and the public.

Health department and water resource managers can now access a truly comprehensive, quality-assured data source for evaluating beach water safety, assessing nutrient loading, and responding to pollution events. Consistent datasets support regulatory requirements, including Clean Water Act assessments, while improving confidence in decision-making.

Since its launch in early 2025, QuickDrops has aggregated more than 100,000 data points from more than 700 monitoring locations across New York and Connecticut. The breadth of available parameters reflects the diverse environmental indicators needed to evaluate marine life health, swimming safety and ecosystem function.  Physical, chemical and microbiological measurements enable detection of trends across sites or the region, comparison of stressors, and identification of potential warning signs of ecological degradation. The overall dataset continues to expand.

By enabling collaboration across community scientists, academic institutions, and regulatory agencies, QuickDrops strengthens the scientific foundation for protecting Long Island Sound. The platform supports informed decision-making, enhances transparency, and contributes to the long-term health and resilience of this critical estuarine ecosystem.
