This dashboard provides a comprehensive analysis of pesticide concentrations in the groundwater and surface waters of US Native Lands, as well as estimated agricultural pesticide use across these lands. By visualizing data from various monitoring stations and county-level estimates, users can explore key pesticide indicators that influence water quality and aquatic ecosystems.
Users can interact with the dashboard to explore pesticide data across different US Native Lands. By selecting specific Native Lands, you can view detailed information about pesticide trends, including concentrations at monitoring stations and estimated pesticide use at the county level. The summary dashboard offers an overview of pesticide use and concentration variations, helping to identify trends and areas of concern.
To get started, click on a Native Land area to view a breakdown of pesticide concentrations or agricultural pesticide use estimates for that region. This tool is designed to facilitate the analysis of pesticide data and its implications for water quality and ecosystem health, aiding informed decision-making and conservation efforts.
Explore the dashboard to gain valuable insights into pesticide data for surface water and groundwater on US Native Lands.
The data used in this dashboard comes from two primary sources: the Water Quality Portal (WQP) and the USGS’s agricultural pesticide use estimates.
The Water Quality Portal (WQP) is the premier source of discrete water-quality data in the United States and beyond. This cooperative service integrates publicly available water-quality data from the United States Geological Survey (USGS), the Environmental Protection Agency (EPA), and over 400 state, federal, tribal, and local agencies. By integrating such extensive datasets, the WQP provides a comprehensive resource for understanding and managing water quality. For more information, visit the Water Quality Portal.
The USGS Pesticide National Synthesis Project (PNSP) offers county-level estimates of pesticide use, providing high and low application ranges for various pesticides. The PNSP synthesizes data from multiple sources to generate annual pesticide use estimates at the county level across the United States. These estimates are invaluable for understanding the potential impact of agricultural pesticides on water quality and ecosystems, particularly on US Native Lands. For more information, visit the Pesticide National Synthesis Project.
These datasets combine to provide a detailed picture of pesticide concentrations and usage, supporting water quality management and environmental health efforts.
Pesticides play a significant role in water quality, with potential impacts on aquatic ecosystems, wildlife, and human health. Agricultural pesticide use can lead to the contamination of groundwater and surface waters, affecting the species that depend on these water sources. Certain pesticides can be toxic to aquatic life, disrupting metabolic processes, reproduction, and survival, while others may accumulate in the food chain, further impacting ecosystem health.
Monitoring pesticide concentrations helps identify areas of concern where pesticide contamination may be affecting water quality and aquatic ecosystems. For example, long-term exposure to high pesticide levels can lead to the decline of sensitive species, impair biodiversity, and alter ecosystem functions. Additionally, pesticide runoff into water bodies can affect dissolved oxygen levels and contribute to eutrophication, which harms aquatic life by reducing oxygen availability.
Understanding the distribution and trends of pesticide use and concentrations is crucial for effective water resource management, conservation efforts, and policy decisions. By providing insights into pesticide use at both the monitoring station and county levels, this dashboard helps decision-makers better assess the risks posed by pesticide contamination, supporting the protection and restoration of water quality across US Native Lands.
