Water Use Impact Assessment - Delineation of water supply source and recharge areas, evaluation of surface water / groundwater interactions including stream depletion evaluations, determination of balanced maximum sustainable production rates, evaluation of contaminant impact sourcing, isotope studies for evaluating water supply sources, chemical groundwater characterization and three dimensional aquifer modeling, contamination mitigation planning, support for California Environmental Quality Act (CEQA) or National Environmental Policy Act (NEPA) documentation, and expert evaluation and testimony.
	Water Resource Development - Full investigation and characterization of aquifer systems, water quality and production capability assessments, watershed evaluation, water balance studies, determination of aquifer yield, production well design and installation, surface and groundwater flow analyses, well permitting support and economic evaluations.
	Water Supply Planning - Development of water resource management plans including forecasted production capabilities, wellhead protection modeling, plans for balancing groundwater and surface water withdrawals, and drought contingency planning.
	Surface Water Quality Evaluation - Water quality sampling and laboratory testing, watershed definition and evaluation, water budget models, wetlands water and sediment sampling, stream flow measurements.

Johnson Wright Inc. staff has assisted public and private clients in the analysis and development of their water resources. Because of the complexities involved in managing water resources, those responsible for solving water supply issues and evaluating overall water needs require proven expertise. JWI uses a combination of advanced field methods, laboratory analyses, and advanced two-dimensional and 3-D modeling techniques to conduct our investigations, analyses, and plan development. Recent typical investigations include groundwater basin conceptual model development, impact analyses for groundwater development to support CEQA and/or NEPA documentation; surface water and wetlands sampling and characterization, spring source investigation, determining connectivity between aquifers, confined and semi-confined aquifer delineation, vertical and horizontal groundwater flow analysis, design, and aquifer pumping evaluations.
