Another way that humans
increase nutrient loads in the lake is through wastwater disposal. There are many ways to process
wastewater in rural areas that have no sewer. Homes in Threemile Pond watershed use pit privies,
holding tanks and septic systems, but of these methods, septic systems are
by far the most common and will be the focus of my presentation.

Through observation and
conversation with local plumbing inspectors and code enforcement officers,
we learned that many septic systems were too near the shore, old, grandfathered and leaky. Grandfathered is a term that refers
to properties that were built before a partictular law was passed and are
therefore exempt from that regulation.

We concluded thatt Septic
systems in the watershed are allowing nutrients and unprocessed wastewater
to seep into the soil, streams and lake.
