IS 16301:2014 is the Indian Standard (BIS) for guidelines for water quality monitoring. This standard provides comprehensive guidelines for establishing and operating a water quality monitoring program. It covers setting objectives, designing monitoring strategies (location, frequency, parameters), sampling procedures, laboratory practices, data management, and reporting for various surface and groundwater bodies.
Provides guidelines for planning, implementing, and interpreting water quality monitoring programs for various water bodies.
| Parameter | IS Value | International | Source |
|---|---|---|---|
| Preservation Temperature for General Samples | Refrigeration at 4°C is recommended as a general technique. | Store at 2 °C to 8 °C, typically in the dark. | ISO 5667-3:2018 |
| Holding Time for Microbiological Samples (Coliforms) | Analyze within 6 hours, or max 24 hours if stored at <10°C (references IS 1622). | Maximum 24 hours if stored at 2 °C to 8 °C in the dark. | ISO 5667-3:2018 |
| Frequency of Field Blanks (QA/QC) | One field blank for every 20 samples collected. | One field blank per day per sampling team, or one per 20 samples, whichever is more frequent. | US EPA Guidance (common practice) |
| Sample Volume for General Chemical Analysis | 2 litres for 'Chemical complete' analysis. | Typically 1-2 litres, often collected in separate bottles for different parameter groups (e.g., 500 mL for metals, 1L for general ions). | ISO 5667-3:2018 |
| pH Sample Holding Time | Analyze immediately (references IS 3025). | Analyse as soon as possible, preferably on-site. If storage is unavoidable, analyse within 24 hours. | ISO 5667-3:2018 |
| Recommended Monitoring Frequency (Rivers, Trend Analysis) | Monthly or quarterly. | Depends on objectives and variability, but monthly is a common frequency in many programs for trend analysis. | ISO 5667-1:2020 |
