Neel WTP algae samples Attachments: JFN WTP bank 200421 Aulacoseirajpg; JFN WTP bank 200421 Scenedesmus and Synedrajpg; JFN WTP intake 200421 Aulacoseira and Pseudanabaenajpg; JFN WTP intake 200421 Cryptomonasjpg; JFN WTP intake 200421 Tetraedronjpg Hi Audrey, Both samples have very low levels of algae and do not look like algal blooms. The algae I did find are typical for freshwaters at this time of year —diatoms, greens, and one cyanobacteria filament. Diatoms and microgreens are indicators of good water quality. I've heard the diatom Aulacoseira can give water a musty taste, but it is harmless. The cyanobacteria Pseudanabaena is very common at this time of year and is not a problem at low levels. If someone gave me these samples and didn't tell me anything about why they were collected, I wouldn't think twice about them —too little algae.

Do not click links or open attachments unless you verify. Send all suspicious email as an attachment to am@nc.gov Elizabeth, Thank you so much for the info and the help. I have shipped a box with two samples UPS. It should be there tomorrow but I did not overnight it. They contain more than 50 mis. One is from our intake area and the other from the bank about 100 yards from the intake. The river is really muddy from the rain yesterday so I don't know how or if that will affect the sample. Thank you again.

Exercise caution when opening attachments or clicking links, especially from unknown senders. Hi Audrey, We are glad to assist and help trouble shoot but cannot do weekly monitoring. Please contact the MRO drinking water plant consultant at 704-663-1699 to see if someone offers those services in your area. Or, contact Corey Basinger or Andrew Pitner (cc'ed above) and ask if you can get a name of someone in the water supply world who could help. Once I get the sample, I will e-mail you later that day with a list of the most numerous types of algae in the sample. Algal samples can give information, but they do not fix problems.

Please send about 50 ml of water in a clean plastic bottle to: Elizabeth Fensin NC Division of Water Resources Water Sciences Section Bio Lab 4401 Reedy Creek Road Raleigh, NC 27607 If you need DEQ staff to investigate, please contact the Mooresville regional office at 704-663-1699. Due to CV19, we are doing a lot of working from home. When the sample is on its way, please e-mail me so I know to come in and receive the sample.
