Biochar As A Means Of Water Purification In Haiti, Caolan Keenan
Biochar As A Means Of Water Purification In Haiti, Caolan Keenan
Honors Projects
Our research set out to determine if biochar, a compound made by burning organic plant matter in a low oxygen environment, would be a suitable means of removing E. coli populations from contaminated water collected from the Grand River in Allendale, MI using simple materials to construct a filter that could be constructed and used in Haiti. Previous research has shown biochar to be effective at trapping bacteria and other contaminants in the porous surface and by binding other non organic contaminants. We constructed multiple iterations of these filters using gravel, sand, and biochar and ran three live tests with …

Ulva is a genus of marine green algae native to many of the world’s coastlines and is especially difficult to identify via traditional methods such as dichotomous keying. This project aims to streamline taxonomic classification of Ulva species through DNA sequence analysis. Local samples of Ulva were obtained from Puget Sound, Seattle, WA, and two target genes (rbcL and its1) were amplified via PCR and sequenced for comparative analysis between samples. Ulvoids have a detrimental impact on marine ecosystems in the Pacific Northwest due to their role in eutrophication-caused algal blooms, and reliable identification can help inform conservation …
