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.
A lumbar peritoneal (LP) shunt is a technique of cerebrospinal fluid (CSF) diversion from the lumbar thecal sac to the peritoneal cavity.
Shunting is successful in reducing pressure in the brain in most people. VP shunts are likely to require replacement after several years, especially in small children. The average lifespan of an infantâs shunt is 2 years. Adults and children over the age of 2 may not need a shunt replacement for 8 or more years.
