CPVEC Sample Data 2000-2009 Ed White CPVEC Environmental Program Specialist

Definitions • Blackwater – water with human waste • Graywater – sink, shower, galley wastewater • mg/L - 1/1,000 gram per liter • µg/L - 1/1,000,000 gram per liter

Why Sample?

Ensuring samples are representative • Quality Assurance/Quality Control Plan • Vessel Specific Sampling Plan • Field notes, chain of custody • Unannounced sampling • Blind duplicates • Field audits • Lab audits

176 Parameters Sampled • “Conventional”- pH, Fecal Coliform, BOD, TSS, Chlorine. (16 parameters) • “Priority”- VOCs (70), BNAs (65), metals (25). • General Permit- Ammonia, Copper, Nickel, Zinc twice a month.

Sample Data Notes: • Frequency of samples taken varies over time • Number of ships sampled changes, individual vessels change • Metal filtering method changed

Conventional Parameters • pH • Fecal Coliform • Biochemical Oxygen Demand (BOD) • Total Suspended Solids (TSS) • Chlorine • Nutrients • Alkalinity
