  1. 1. Facility Wastewater Discharges and Pollution in MA: a Water Quality Analysis Katelyn Tarrio, Casey Kelly, Kaitlin Walker (Boston University) http://www.econse.com/solutions/waste-water/
  2. 2. Background http://fossilfuel.energy-business-review.com/news/us-epa-sets-new-limits-for-pollutants-discharge- from-steam-electric-power-plants-011015-4683531
  3. 3. 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. 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)
  5. 5. Results Facility Town Westfield Wastewater Treatment Plant Westfield Westerly Wastewater Treatment Facility Marlborough Charles River Wastewater Treatment Facility Medway Massachusetts Correctional Institution (MCI) Norfolk/Walpole New Bedford Wastewater Treatment Facility New Bedford

  9. 9. New Bedford Wastewater Treatment Facility * = Over limit at some time during year 0 1000000 2000000 3000000 4000000 5000000 6000000 2012 2013* 2014* 2015* 2016* Poundsperyear(lb/yr) Year Total suspended solids load Total pounds discharged Maximum allowable load
  10. 10. Westerly Wastewater Treatment Facility 0 1000 2000 3000 4000 5000 6000 2012 2013* 2014 2015 2016* Poundsperyear(lb/yr) Year Phosphorus Load Total pounds discharged Maximum allowable load * = Over limit at some time during year
  11. 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
  12. 12. Thank You
