Tolerance Requirements for Remote Handling at the Hanford Vitrification Project
A new and innovative approach to installation of the many remote nozzles and electrical connectors that must be installed to demanding tolerances has been developed by the architect/engineer...
An Isolated Wetland Used for Stormwater Treatment
A marsh used for stormwater management showed gradually increasing levels of pH, dissolved oxygen and conductivity in the flow path. The system was especially effective in removing suspended...
Water Quality Impacts from Development of Port Ludlow, Washington
Port Ludlow Bay is a tidal estuary located adjacent to Admiralty Inlet in Puget Sound, Washington. A planned development has been under construction along the bay since 1976. A 0.64 mgd...
Water Quality Model of the Chicago Waterway
In 1992, the Metropolitan Water Reclamation District of Greater Chicago (the District) developed a QUAL2E water quality model of the Chicago waterway and Upper Illinois waterway. The model...
Seasonal Water Quality Management Given Sparse Data
An approach for designing robust seasonal water quality management programs for river basins with sparse or short flow records is presented. This approach uses Markov chain modelling and...
A Planning Strategy for Safe Drinking Water Act Compliance
This paper presents a simple planning strategy for drinking water utilities that will allow them to move ahead with system upgrades and specific regulatory compliance programs even though...
Investigation and Rehabilitation of the Moses Lake Larson Wellfield
In 1988, low levels of trichloroethylene (TCE) were detected in several of the Larson wells operated by the City of Moses Lake. The wells are up to 800 feet deep and are completed in fractured...
Strategies for Developing Major Capital Facilities
Siting, permitting, and mitigating impacts present many challenges during the development of major capital facilities. As a result of the need for public involvement, environmental review,...
