Description

The State of Arizona, through its Department of Environmental Quality, is seeking one or more contractors to provide technical expertise and support for the development, revision, and implementation of Arizona Surface Water Quality Standards (SWQS). The work will be performed on a task‑order basis, with services ranging from statistical analysis of water‑quality data to limnology, stream hydrology, and the drafting of regulatory standards. The contract is initially for a 12‑month term with possible extensions up to five years, and pricing is based on fixed hourly rates. • Technical services include numerical/statistical analysis, lake limnology, stream hydrology, and development of CWA‑compliant water‑quality standards. • Deliverables will be defined in individual Task Orders and may include reports, data analyses, stakeholder response support, and training. • Contractor must provide qualified personnel (engineers, scientists, statisticians) meeting specified experience and education thresholds, maintain required insurance, and submit weekly progress reports.
