A client operates an ongoing Watershed Protection Program (WPP) to protect its water supply. Plummer assisted in developing and incorporating a spill response plan into the WPP.
Plummer developed a dissolved oxygen model that couples the FREHD hydrodynamic code (Hodges, 2012) and EPA WASP 7 to simulate dissolved oxygen in Oso Bay.
To support permitting of a discharge of treated wastewater effluent from a new wastewater treatment plant, Plummer developed a QUAL-TX model from HEC-RAS cross-sections of the receiving stream.
To support permitting of a discharge of treated wastewater effluent from a new regional wastewater treatment plant, Plummer assisted the NTMWD in developing a QUAL-TX model and a plan for collecting field measurements of stream geometry and flowrates.
To support permitting of a discharge of treated wastewater effluent from a new regional wastewater treatment plant, Plummer assisted the NTMWD in developing a QUAL-TX model and a plan for collecting field measurements of stream geometry and flowrates.
Plummer updated the TCEQ’s regulatory model for the Upper Trinity River to a newer version and incorporated revised background flows.
As regulatory limits on nutrients and algae become an increasing reality in Texas, it is imperative that a reliable and site-specific approach be developed for establishing Texas Pollutant Discharge Elimination System (TPDES) permit effluent quality limits for nutrients.
Using the Water Quality Analysis Simulation Program (WASP), Plummer developed and calibrated a water quality model of Grapevine Lake.
The 2014 Austin Water Resource Task Force recommended that the City of Austin evaluate the feasibility of IPR in Lady Bird Lake (LBL) as one of several water supply strategies for consideration in the City’s integrated water resources plan.
Plummer developed a monthly water balance model of Lavon Lake and the NTMWD water supply system to support evaluation of different water supply and water treatment management options.
Plummer developed a CE-QUAL-W2 model of Lavon Lake to evaluate impacts on dissolved oxygen, nutrients and chlorophyll-a levels in the lake.
Using the EPA’s Water Quality Assessment Simulation Program (WASP), Plummer developed an advanced water quality model of Lewisville Lake to support a TPDES permit renewal for the Lakeview Regional Water Reclamation Plant.
NTMWD sought to model nutrient loading from the Lavon Lake watershed and its impacts on water quality in Lavon Lake by coupling a SWAT model of the watershed with a CE-QUAL-W2 model of the lake.
