The watershed program offers technical assistance to watershed groups, municipalities, and individual citizens. A watershed is a geographic area of land across which water, and the sediments and dissolved materials it contains, flow on their way to a single common outlet -- a stream, lake or river.
What is Lumboperitoneal Shunt? Lumboperitoneal (LP) shunt is an artificial connection created by neurosurgeons which allows excess of cerebrospinal fluid to leave the subarachnoid space and enter the peritoneum. From there, the fluid is easily absorbed and eliminated via the circulatory system and the kidneys.
Lumbar puncture (spinal tap) Overview. A lumbar puncture (LP), also called a spinal tap, is an invasive outpatient procedure used to remove a sample of cerebrospinal fluid (CSF) from the subarachnoid space in the spine. (This test is similar to a blood test, in which a needle is inserted into an artery to collect blood for testing.)
