Sure! Here are common methods used to remove chemical contaminants like lead from water, categorized by effectiveness:

### Effective Methods:
1. **Activated Carbon Filters** - Effective in reducing lead levels by adsorbing contaminants.
2. **Reverse Osmosis Systems** - Highly effective at removing lead and other contaminants.
3. **Distillation Units** - Removes lead by vaporizing water and condensing it back into liquid form, leaving contaminants behind.
4. **Water Softeners** - Some water softeners can reduce lead levels, especially those designed with specific filtering capabilities.

### Ineffective Methods:
1. **Regular Faucet Filters (without specific lead removal capabilities)** - May not effectively remove lead unless specifically certified to do so.
2. **Boiling Water** - Ineffective; boiling does not remove lead; it may actually concentrate it.
3. **UV Water Purifiers** - While effective against bacteria, UV does not remove chemical contaminants like lead.

Feel free to adjust or confirm any particular items if you have a specific list in mind!
