http://www.econse.com/solutions/waste-water/
Background
http://fossilfuel.energy-business-review.com/news/us-epa-sets-new-limits-for-pollutants-discharge-
from-steam-electric-power-plants-011015-4683531
Research objectives
• Identify facilities that could be
contributing to a waterbody
impairment via permit violation
—Analyze trends at these sites
➢ Pollutant types
➢ Annual pollutant loads
➢ Compliance history
• Note areas for future research
Charles River Pollution Control Facility (Google Earth)
Methods
1. Use DMR pollutant loading tool to
identify/filter facilities
2. Map sites alongside impaired
waterbodies
(MassDEP’s 2014 Integrated List of
Waters 305b/303d)
3. Assess facility-specific trends from
EPA’s Discharge Monitoring Report
(DMR) and Enforcement and
Compliance History Online (ECHO)

Conclusion
and
Future Work
Major findings:
• Pollutant trends: some facilities consistently in
violation
• 26% of sites discharging to impaired waters have
expired permits
• Demonstrates a practical, visual method of
water quality analysis
Ø Moving forward: data clarification and
community engagement
Thank You

Research objectives • Identify facilities that could be contributing to a waterbody impairment via permit violation —Analyze trends at these sites ➢ Pollutant types ➢ Annual pollutant loads ➢ Compliance history • Note areas for future research Charles River Pollution Control Facility (Google Earth)
  • 4. Methods 1. Use DMR pollutant loading tool to identify/filter facilities 2. Map sites alongside impaired waterbodies (MassDEP’s 2014 Integrated List of Waters 305b/303d) 3. Assess facility-specific trends from EPA’s Discharge Monitoring Report (DMR) and Enforcement and Compliance History Online (ECHO)

  • 11. Conclusion and Future Work Major findings: • Pollutant trends: some facilities consistently in violation • 26% of sites discharging to impaired waters have expired permits • Demonstrates a practical, visual method of water quality analysis Ø Moving forward: data clarification and community engagement
