Operation Clearwater


Severn River Association's "Operation Clearwater" monitors summer river water quality as indicated by the presence of microorganisms.

Operation Clearwater monitors summer river water quality as indicated by the presence of microorganisms at a number of sites along the Severn, Magothy, and West/Rhodes  Rivers.  In addition, sites along Rock Creek are also being monitored.

Staff at the Environmental Center have participated in a program started by the Severn River Association 27 years ago entitled "Operation Clearwater". This program's goal is to monitor the microbial water quality at bathing beaches and marinas throughout the local river watersheds. Dr. Tammy Domanski, of the AACC Biology Department and Environmental Center, serves as the scientific director of this program after over 20 years under the direction of Dr. Sally Hornor. Water samples at waterfront communities are collected weekly or bi-weekly between mid-May and the end of August, and enumeration of microorganisms associated with poor microbial water quality is performed at the Environmental Center.

Samples are collected on Wednesday mornings by a student employed by the Environmental Center to work on this project. Water is collected in sterile bottles from piers or beaches and kept on ice until all samples are returned to the lab by mid-day.  Data are posted within 24 hours to
