Exposure map submit

Today's goal: Assemble and submit a completed environmental exposure map for Problem 4.
What a finished product looks like
This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.
Title: Lead Exposure Map, Older-Housing Neighborhood.
1. Pathway: lead pipes (source) to drinking water (medium) to ingestion (route) to nervous system (target). Most at-risk population: young children.
2. Data: average tap lead 13.2 ppb; highest home 22 ppb; EPA action level 15 ppb (cited: EPA Lead and Copper Rule). Two of five homes met or exceeded the action level.
3. Mitigation: filters now (fast, low cost) plus pipe replacement (permanent). Recommended both, filters first.
4. Plain-language risk statement for non-experts: 'Some homes here have more lead in their tap water than the safety limit allows. Lead is most harmful to young children. Using a certified filter and replacing old pipes lowers the risk.'
Citations: EPA Lead and Copper Rule action level (epa.gov); city water-quality report.
Tracker: marked Problem 4 exposure map as submitted.

Also due today: Submit the finalized exposure map in the course LMS and confirm in your tracker.
