Compact 5x8 inch notebooks fit easily in pockets or equipment bags. Larger 8.5x11 inch versions provide more writing space for detailed notes and graphs.

Choose notebooks with waterproof covers and synthetic paper. Store them in sealed plastic bags when not in use to prevent moisture damage.

Standard paper absorbs moisture and may tear. Synthetic or treated paper maintains legibility even when exposed to splashes or high humidity.

Retain records for at least one year or according to local health regulations. Longer retention helps demonstrate consistent water quality management.
