has many areas of sandy soils with high water tables. In the recent
past, this sand has been mined for commercial purposes, resulting in a sand pit
that fills with groundwater. Residential and commercial development
quickly occurs around the resulting lake. Storm water drains from
the residential lawns, parking lots, driveways and roads, where it is directed
into the lake.
The Big Slough Creek runs through and connects some of these
sand pits. Because of the diversity of development in this
watershed and also because of the permeable soils and high water table, there is
concern about the effect of storm water runoff on surface and groundwater in the
area. Storm water may carry with it pollutants such as petroleum
products, fertilizers, fecal coliform, and other contaminants from unknown
Six sand pits have been studied within this area.
Three monitoring wells for each sand pit were drilled according to
specifications of the United States Geological Survey. Testing of
these wells has been undertaken in order to determine which pollutants (if any)
are present and whether they are filtered out through the sand prior to reaching
the groundwater. Once the type of contaminant is determined, the
appropriate best management practice (BMP) can be implemented.
An extension to this project has been initiated in the
neighborhood. The water quality specialist for Sedgwick County Conservation
District coordinates the storm water sampling in this specific drainage area.
The goal is to determine whether pollutants carried by storm
water runoff into sand pits affects the quality of the groundwater underlying
and surrounding these pits.
Mission: To assure quality public services that provide for the present and future well-being of the citizens of Sedgwick County.
