Farms and gardens (including lawns!) have the potential to significantly impact ground water quality.
OSU online publications relating to farm and gardens:
Irrigation Water Quality
- Plants vary in their sensitivity to salt, boron, arsenic and other water quality parameters.
- The season or stage of plant growth also affects sensitivity of individual plants.
- Recommended limits for arsenic in reclaimed irrigation water are 0.5 mg/l for long-term use and 2.0mg/l for short term use.
