Drinking Water · Wastewater · Advanced Treatment
Clarity, compliance, and control for every water system.
Practical, field-tested guidance for water treatment, water quality, wastewater, and advanced treatment, with a commitment to safe, affordable drinking water for every community.
What I Do
Four disciplines. One standard: water you can trust.
From the first stage of treatment to the most advanced purification technologies, every project draws on hands-on operations experience and current regulatory knowledge.
Water Treatment
Coagulation, flocculation, sedimentation, filtration, and disinfection: the fundamentals of safe drinking water. I help agencies and operators troubleshoot process upsets, optimize chemical dosing, and keep clearwell and distribution operations within compliance.
Water Quality
Water quality is where chemistry meets public health. I provide monitoring program design, sampling protocol review, and root-cause analysis for water quality complaints and exceedances, so problems are traced to their source and corrected for good.
Wastewater Treatment
From activated sludge and clarification to nutrient removal and biosolids handling, I support wastewater operations with process troubleshooting and capacity or permit-compliance reviews.
Advanced Water Treatment
As water systems face emerging contaminants, drought, and stricter discharge limits, advanced treatment is becoming essential. I help agencies evaluate options, plan implementation, and operate these next-generation processes with confidence.
Equity & Environmental Justice
Safe water is a right, not a privilege.
Too many underrepresented, rural, and low-income communities still live with aging infrastructure, contaminated sources, and water they can't trust. Environmental justice is at the center of how I work: making sure the communities most burdened by pollution and underinvestment get the same technical rigor and attention as any large utility.
