  • In 2003, the Imperial Irrigation District signed the Quantification Settlement Agreement, in which they transferred the water from agricultural runoff that formerly fed the Salton Sea to supply municipalities in Southern California. The agreement kept water flowing into the lake until 2018 in order to give time to come up with ways to mitigate environmental effects of the lake's desiccation. These solutions have not materialized.
  • UCR scientists are collecting dust for microbial analysis

The "Disparities in Environmental Exposures and Health Impacts" project has four goals:

  1. To establish a community advisory board to provide local stakeholder input;
  2. To identify spatial patterns and trends in population exposure and in pollutant transport;
  3. To distribute particle collectors at sites that represent the range of sources of particulate matter and to identify the elemental and biological composition of particles;
  4. To use environmental chamber exposure studies to develop a protocol for monitoring pulmonary inflammation impacts of aerosol particulates identified from the particle collectors.

  • Investors who left in the first half of the 20th century
  • Residents who remained in the area (highly Latinx)
    • Labor exploitation, especially of immigrants through programs like the Bracero program
  • Indigenous groups - especially the Torres Martinez, 40% of whose land is underneath the Salton Sea
  • Agriculture
    • Historically not identified as an unwanted land use, which allowed farmers to get away with more than other industries

Facilities and enforcement case searches can both easily be limited by geography (EPA region, city, state, zip code, county, proximity to national border, and watershed). The tool also automatically produces maps that allow users to see the distribution of facilities across space.

3. What data is drawn into the data resource and where does it come from?

This database uses a broad variety of data. Most of the data is collected by the EPA itself. Users are able to search for facilities regulated under the following systems:

  • Risk Management Plan (RMP)
  • Toxic Release Inventory (TRI)
  • National Pollutant Discharge Elimination System (NPDES) - under the Clean Water Act
  • ICIS-Air
  • Resource Conservation and Recovery Act (RCRA) - hazardous waste
  • Safe Drinking Water Act (SDWA)
  • Superfund Enterprise Management System (SEMS)
  • Clean Air Markets Division Business System (CAMDBS)
  • Greenhouse Gas Reporting Program (GHGRP)
  • Emissions Inventory System
  • Toxic Substances Control Act (TSCA)

When looking at individual facilities, the database provides detailed facility reports, enforcement case reports (civil and criminal), air pollutant reports, effluent charts, pollutant loading reports, effluent limit exceedances reports, CWA program area reports, permit limits reports, and other facility documents as available. The database provides easy ways to download and map the data. The database also allows users to narrow facilities searches using demographic data from EJScreen (also maintained by the EPA), the U.S. Census, and tribal land data.

Users can also look for information on federal administrative and judicial enforcement actions through an enforcement case search.
