Septic Systems Are Only A Small Part Of The Problem
About a decade ago, as part of an environmental restoration grant application, about 500 homes near the river were reported to have septic tanks. That number has not changed significantly in the last ten years, in part because most home construction since then have been connected to sewer systems rather than septic tanks.
Yet, we have an increasingly damaging problem with pollution entering the May River.
“The clearing of land for sprawling suburban development is directly linked to the impaired waterways because without enough natural land cover left intact to serve its filtering function, stormwater carries sediment and pollutants across impervious surfaces and directly into the rivers.” (Schueller & Holland, 2000).
While efforts to provide sanitary sewers as broadly as possible are encouraging, these efforts can also divert attention from the leading cause of polluted runoff – poor planning and inappropriate development patterns leading to sprawl.
Similarly, the limited focus of current testing is hindering our monitoring efforts. Testing that is infrequent or that is restricted to only fecal coliform provides little information about safety risks and long term pollution trends. Because of these testing limits, we actually don’t know how safe it is to swim in the headwaters of the May River. Per the Coastal Conservation League, “if the greater Bluffton area is developed according to the approvals as they currently exist, impervious surface will exceed 20% in the May River watershed and edible May River oysters will be a thing of the past.”
So, while the removal of septic tanks is a small part of the solution, it is not, in and of itself, the total solution. We need to focus on smarter land use. Without correcting our problems with suburban sprawl, we will not succeed.
