(FAIRFAX, VA – August 19, 2014) – Phill Yi, Wendell Khunjar, Katya Bilyk, Ron Latimer, and Paul Pitt of Hazen and Sawyer have co-authored an article in the August 2014 issue of WE&T titled Sensor calibration, maintenance, and validation.

Analytical devices are emerging as an integral component of water resource recovery facilities (WRRFs); these devices help automate data collection and can be used for controlling operations. To facilitate more widespread adoption of sensors for beneficial use at WRRFs, there is a need to increase knowledge transfer among utilities regarding best practices for selection of appropriate sensors, as well as appropriate methods of maintenance, calibration, and data validation. Standardizing approaches and identifying strategies for troubleshooting problematic sensors can help counteract any distrust in sensor data quality and accuracy in measurements.

This article, also co-authored by Charles Bott (Hampton Road Sanitation District – Virginia Beach, VA.). Maureen O’Shaughnessy (Prince William County Service Authority – Woodbridge, VA), and Michael Rumke (Broad Run WRF with Loudoun Water – Ashburn, VA), covers three case studies from WRRFs in the Mid-Atlantic region, where sensors have been used for various purposes.

Since our founding in 1951, Hazen and Sawyer has focused on two things: providing safe drinking water and controlling water pollution. Our range of services encompasses the planning, design, and construction management of water and wastewater-related projects – from clean water treatment, storage, and distribution to wastewater and stormwater collection, treatment, and reuse.
