NITROGEN & PHOSPHORUS REMOVAL FROM GROUNDWATER LITTLE BOGUE, MS. CONSTRUCTED NOVEMBER 2009

RS2 Test Site: Little Bogue, Elliott, MS On the narrow mid-bank bench (average width ft, approx. 8 ft above the streamside floodplain bench), a trench a bucket wide (1.0 ft) was dug to a depth of 4 ft. This should intercept a large amount of shallow groundwater.

RS2 Test Site: Little Bogue, Elliott, MS There is a 75 ft long control section (nothing done, no trench, just monitoring instruments), and a 150 ft long test trench section. Within the downstream 75 ft of the test trench, three 25 ft-long test plots of adventitious rooting poles of Black Willow, Sycamore, & River Birch were placed, spacing varied from 1 to 2 ft.

RS2 Test Site: Little Bogue, Elliott, MS For the test section shovels were used to backfill the trench with a mix of 20% (by volume) Aluminum Sulfate, xx% mulch, and the remainder native soil from the trench. This effectively planted the live poles to a depth of 4 ft.

RS2 Test Site: Little Bogue, Elliott, MS Monitoring instruments determine performance of the control and planted & not planted test sections. Instruments at different depths will determine if some groundwater is bypassing the test trench.

RS2 Test Site: Little Bogue, Elliott, MS According to the CSU laboratory tests, the Aluminum Sulfide and carbon (mulch) should greatly reduce the Nitrogen & Phosphorus load to the stream.

Install instrumentation as required. Monitor for long-term project performance. 200 ft RS2 Test Site: Little Bogue, Elliott, MS - aerial view

LET’S DO SOME RESEARCH !!

Hand labor is used to mix Aluminum Sulfate & mulch into backfill. Next time an excavator will be used to mix and backfill, we are learning!! No plantings in this first 75 ft. CONSTRUCTION-RS2 PROJECT-LITTLE BOGUE PIX BY DAVE DERRICK
