Water Quality

Rick Sullivan has been our prime water quality tester for Secchi and DO for the past years. He has welcomed students from St. Joseph’s College to join him as they learn the methods of testing. The students are now taking chlorophyll and phosphorus samples which are taken back for analysis in the lab. Professor Emily Lesher reached out and asked if she could bring students to our lake for a training session on how to take samples for microplastics. This is not PFAS

Little Sebago Lake has heighted to include multifaceted testing; Secchi disc measuring clarity, dissolved oxygen with DO meter for oxygen content, chlorophyll and phosphorus added last year and newly added this year microplastic testing. Last year LSLA began testing various streams entering the lake, as well. Stream testing this year met a degree of difficulty due to the drought that provided little running water which is needed for testing. We hope to continue this again next year weather permitting. Phosphorus and Chlorophyll Sampling L to R: Lilly Souweine (sophomore), Maddie Zordan (sophomore), Maeghan Perkins (sophomore)

Microplastic Sampling L to R: Professor Emily Lesher, Hannah Vacco (sophomore), Ethan Smith, (freshman), Ben Fargo (freshman), Seth Quinney (freshman), Hunter Grant (freshman)
