Environmental Engineering Swift Creek Reservoir Water Quality Reports

After 10 years of consistent monitoring, the Addison-Evans Water Plant laboratory took part in a review of the Swift Creek Reservoir water quality sampling and analysis program. View the Environmental Engineering Swift Creek Reservoir Water Quality Reports Archive.

It was decided more emphasis will be placed on newer technologies by use of probes and sensors. The laboratory uses more probe-based sondes in the field and monitors real-time numbers by way of the LG Sonic buoy system.

Currently, data end users and experts in interpretation of reservoir water quality place more emphasis on total phosphorus and total nitrogen. It was found that the time and effort to measure nitrogen and phosphorus components of orthophosphate and ammonia is less valuable; therefore these parameters will be dropped and more time will be spent measuring and reacting to the newer technology data.

These changes will ensure the reservoir program is current with technology/theory, data processing efficiency and enable staff to concentrate efforts on issues important to the continued monitoring of water quality in the reservoir.
