Water Quality

Livestock

---

6.1 Effects

To our knowledge, no known effects of dissolved or total organic carbon to livestock have been documented at levels that are likely to occur in livestock water.

6.2 Literature Guidelines

There are no criteria specific to livestock watering available from any other jurisdiction.

6.3 Proposed Guidelines

There is insufficient information to derive water quality criteria for total and dissolved organic carbon for this water used.

6.4 Rationale

The limited information on the toxicity of humic and fulvic acids to mammals (see Section 3.2 of BC Environment 1998a) indicates that livestock are not likely to be adversely affected by waters with high levels of organic carbon. If the water was to impart a toxic effect to livestock, it would be due to other physical, biological and/or chemical parameters in the water. Existing criteria for these parameters should protect livestock from being harmed.
