Keeping the Pond Healthy, bubbling air through the pond raises the levels of absorbed gases, promoting plant growth and providing more dissolved oxygen for animal life. The choice of plants helps, too. Here, we do well for watercress.
Examining solely chemical, physical, or biological metrics can provide insights into water quality, but they must paint the complete picture. While bioindicators can suggest water quality levels, they don't elucidate the root causes. For instance, a sample's absence of sensitive species implies poor water quality, but it doesn’t pinpoint the specific issue. A comprehensive understanding emerges only when we evaluate both physical and chemical aspects. Hence, while bioindicators are an effective preliminary method to gauge water quality and identify areas requiring attention, they should be complemented with additional data collection techniques.
EPT Index
The EPT Index uses pollution tolerance levels of different macroinvertebrates to indicate water quality. It is named after the three orders of macroinvertebrates that are assessed: Ephemeroptera (mayflies), Plecoptera (stoneflies), and Trichoptera (caddisflies)
