MWRA Compliance: Proper Disposal of Lab Sink Waste
Hello C2I Community,
Effective Immediately: Lab Sink Wastewater Disposal Policy
To ensure MWRA compliance and maintain a safe laboratory environment, we are reinforcing proper wastewater disposal procedures at all lab sinks.
Please DO NOT dispose of any chemicals or solvents into the sinks—this includes 70% ethanol, alcohols, or any other chemical solutions. Only typical 10% bleached cell media waste may be disposed of in the designated sinks. Please look for posted signage indicating whether bleach disposal is allowed. Sinks that are strictly bleach‑free, and are clearly labeled as such.
Glassware Cleaning Requirements
All dirty glassware must be free of chemical residues before being washed in the sink.
Please follow the required steps:
Triple‑rinse all glassware with water inside the fume hood to remove any residual solvents.
Collect all rinsate as chemical waste inside the fume hood—do not pour it down the sink.
Only after triple-rinsing and removing all chemical residues may the glassware be washed at the sink.
If you have any questions or concerns, please don't hesitate to contact the C2I Team.
Thank you for your attention to this matter.
The C2I Team
