TNFD C2.1 Volume of water discharged split into:
• Total
• Freshwater; and
• Other.
Pollutants and water quality metrics to report include:
• pH;
• TSS (Total Suspended Solids);
• TDS (Total Dissolved Solids);
• Mercury;
• TPH (Total Petroleum Hydrocarbons);
• BOD (Biochemical Oxygen Demand);
• Dissolved solids; and
• Suspended solids.
Including: Concentrations of key pollutants in the wastewater discharged, by type of pollutant, referring to sector-specific guidance for types of pollutants; and Temperature of water discharged, where relevant.
Guidance for EN/BE/RE/RS: Reporting of water discharged under the core global disclosure metric should additionally be broken down by destination:
• Surface water;
• Groundwater;
• Seawater; and
• Third-party water, and the volume of this total sent for use to other organisations.
Pollutants to report under the core global disclosure metric include:
• Dissolved solids; and
• Suspended solids.
Thermal - an organisation should include thermal discharges.
Oil & Gas - In reporting this core global disclosure metric, the
organisation should include:
• The volume of produced water and flowback
generated.
This should be broken down by percentage:
• Discharged;
• Injected; and
• Recycled.
Pollutants to report under this core global disclosure
metric include:
• Hydrocarbons in both produced water and process
wastewater (mg/litre); and
• Chemical additives, metals, naturally occurring
radioactive material (NORM) and salts.
In reporting this core global disclosure metric, the
organisation should include the number of incidents of
non-compliance associated with water quality permits,
standards and regulations. Typical parameters of
concern include hydrocarbons (including oil and grease),
chemical oxygen demand (COD), biochemical oxygen
demand (BOD), sulphides, ammonia, phenols, total
suspended solids (TSS) and total dissolved solids (TDS).

AWS 1.5.4 Water quality, including physical, chemical, and biological status, of the catchment shall be identified, and where possible, quantified. Where there is a water-related challenge that would be a threat to good water quality status for people or environment, an indication of annual, and where appropriate, seasonal, high and low variances shall be identified.
AWS 1.3.4 Water quality of the site’s water source(s), provided waters, effluent and receiving water bodies shall be quantified. Where there is a water-related challenge that would be a threat to good water quality status for people or environment, an indication of annual, and where appropriate, seasonal, high and low variances shall be quantified
AWS 1.3.5 Potential sources of pollution shall be identified and if applicable, mapped, including chemicals used or stored on site.

W1.2i Provide total water discharge data by destination
W1.2k Provide details of your organization's emissions of nitrates, phosphates, pesticides, and other priority substances to water in the reporting year.
