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
