Position Summary

The General Chemistry (Wet Chemistry) Analyst is responsible for performing routine to moderately complex wet chemistry analyses in a high-throughput environmental laboratory. This role requires hands-on experience with classical and instrumental wet chemistry techniques, including titrations, gravimetric analyses, colorimetric procedures, and bench-scale sample preparation across multiple EPA, Standard Methods (SM), and client-specific protocols. The Analyst is expected to execute analytical work efficiently while maintaining strict adherence to quality systems, regulatory requirements, and laboratory safety protocols. This position plays a key role in ensuring accurate, defensible data to support environmental compliance, permitting, and monitoring programs.

Primary Responsibilities

Analytical & Instrumental Responsibilities

• Perform wet chemistry analyses using EPA, Standard Methods, and client-specific procedures, including but not limited to alkalinity, hardness, nutrients, solids, demand parameters, and select inorganic determinations
• Execute analytical techniques such as titration, gravimetric analysis, colorimetry, spectrophotometry, and bench-scale digestion or extraction
• Operate and maintain laboratory instrumentation including UV-Vis spectrophotometers, discrete analyzers, balances, ovens, furnaces, pH meters, and autotitrators
• Prepare reagents, standards, and calibration solutions in accordance with SOP and method requirements
• Perform routine instrument checks, calibrations, and maintenance as required

Production & Sample Management

• Manage assigned sample workloads to meet strict turnaround times in a deadline-driven production environment
• Accurately track holding times, and follow established chain-of-custody and sample handling procedures
• Perform analytical batches efficiently while maintaining data quality and regulatory compliance
• Maintain a clean, organized, and inspection-ready laboratory workspace

Quality Assurance & Regulatory Compliance

• Ensure compliance with EPA, Standard Methods, state regulations, client requirements, and accreditation standards (TNI/NELAC)
• Perform and evaluate method-required QA/QC including blanks, LCS, duplicates, matrix spikes, and calibration verifications
• Identify out-of-control conditions and notify Laboratory Operations or QA for corrective action
• Maintain complete, accurate, and defensible raw data, calculations, and bench sheets
• Adhere to SOPs, safety protocols, and data integrity requirements at all times

Method Support & Continuous Improvement

• Support implementation of new methods under supervision of senior staff
• Assist with method validation, verification, and performance studies as directed
• Participate in continuous improvement initiatives related to efficiency, quality, and safety
• Provide input on SOP updates, reagent optimization, and workflow improvements

Collaboration & Communication

• Communicate workload status, analytical issues, and potential turnaround risks to supervisors and laboratory operations staff
• Document analytical challenges, deviations, and resolutions clearly and concisely
• Work collaboratively in a team-oriented, safety-focused, and quality-driven laboratory environment

Required Knowledge, Skills, and Abilities

• Working knowledge of wet chemistry principles and laboratory best practices
• Experience with titrations, colorimetric analyses, gravimetric techniques, and quantitative calculations
• Familiarity with EPA and Standard Methods commonly used in environmental general chemistry (e.g., nutrients, alkalinity, hardness, TSS/TDS, COD/BOD support)
• Strong attention to detail and commitment to data accuracy and integrity
• Ability to follow detailed SOPs and regulatory requirements
• Strong organizational and time-management skills in a production setting
• Proficiency with laboratory information management systems (LIMS) and electronic recordkeeping

Required Education and Experience

• Bachelor's degree in Chemistry or a related scientific discipline
• Minimum of one (1) to three (3) years of hands-on experience performing wet chemistry analyses in an environmental laboratory
• Demonstrated experience with at least one EPA or Standard Method wet chemistry procedure in a regulated setting

Preferred Experience and Knowledge

• Experience performing multiple general chemistry parameters in a high-throughput environmental laboratory
• Familiarity wi
