Dear All,
In the 6-8 years since I have walked to the turnaround and stand of=20
Scouring Rush (Equisetum hyemale) on this ATV trail, not much has=20
changed. The Equisetum stand is less vigorous but still large.
Both stands of this horsetail which I know of in Kings county are=20
not on calcareous soil (solubility of SiO2 increases with increase in=20
pH) but instead are near the base of sandy ridges where downslope=20
seepage saturated with SiO2 may be expected.
The swail and stream, which receives leachate from the abandoned=20
dump, is now more pungent (H2S leading to SO2) than usual and the Ferric=20
Oxide coating of temporarily flooded areas is very rich; indicative of=20
enhanced anaerobic alteration of dump contents. Calla palustris is still=20
there. The brook now flows through a culvert; easier for ATV traffic and=20
hikers.
A sample well, which to judge from the path leading to it from the=20
dump gate is frequently sampled, is carefully located so no leachate=20
from the landfill will be detected.
The highway end of this road, now gated, used to serve as a lover's=20
lane. With reduced motor vehicle traffic the former bare sand sections=20
are partially vegetated and less attractive to Tiger Beetles.
