TranscriptionSegment 45 "Drinking Water Contaminants" Air Date: 12/9/03 Anchor intro: Lake Tahoe is considered one of the clearest and cleanest bodies of water in the world. Yet, despite it's incredible clarity, parasites like cryptosporidium and giardia have been detected in the lake. Shelly Purdy has more in tonight's Lake Tahoe Report. ((Take Pkg)) ((nats - water lapping on shore)) ((Track 1)) The old saying what you can't see won't hurt you isn't necessarily true when it comes to microscopic parasites like giardia and cryptosporidium. These disease- causing organisms are found in water sources around the world?and Lake Tahoe is no exception. ((sot @ 12:15 Carl Ruschmeyer, Douglas County Engineer)) "They've been detected here in both Lake Tahoe and the backcountry lakes and streams, but typically in very low concentrations." ((Track 2)) Giardia and cryptospoirdium gets into lakes and streams from the feces of infected animals and people. It takes only a small amount to contaminate an entire water source. ((sot @ 14:53)) "Direct human contact in water especially on the beaches. Infants and even potty trained children in diapers, so any kind of feces can be deposited into the lake?))" ((sot @ 15:03)) "Dogs commonly carry it. People love to bring their dogs to the beach and let them swim, so that could be a source." ((Track 3)) By law, drinking water is treated for giardia and will soon be for cryptosporidium. The chances of getting sick from a treated water supply are extremely rare, but if you drink straight from lakes and streams you run a greater risk. Giardia can be treated with antibiotics, but cryptosporidium is a different story. ((sot @ 23:24 Make Walker, University of Nevada)) "If you contract cryptosporidium you rely on your body?s immune system to clear the infection because there isn?t a drug therapy that?s effective against cryptosporidium right now." ((Track 4)) Luckily our backyard water park - Lake Tahoe - is so pristine, the chances of getting sick from giardia or cryptosporidium are very low. With the Lake Tahoe Environmental Education Coalition, I'm shelly Purdy for kolo news channel 8. Anchor Tag: Giardia and cryptosporidium can be fatal for people with compromised immune systems such as chemotherapy patients, young children and people suffering from AIDS or HIV.
