Highland Rim
built 656 days ago
The Highland Rim aquifer system is an important source of drinking water. It supplies most of the rural, domestic and many public supplies of drinking water in the Highland Rim. Where there is a dynamic flow system, dissolved-solids concentrations are less than 500 milligrams per liter. However, isolated cells may exist where the ground water has dissolved-solids concentrations of more than 1,000 milligrams per liter.

Preview: This ridge-running trail at Beaman Park winds through Highland Rim woodlands to end among big oaks. Never too steep, the path ... offers views into incredibly precipitous hollows that cut deep into the Highland Rim. The Highland Trail at Beaman Park was a long time in the making. The 1,500-acre tract was purchased by the city of Nashville in 1996, and it took nearly ten years from the time of purchase until the park was open for unsupervised visitation as it is today. The Highland Trail will show you that this part of Davidson county is rugged, steep, and still a little wild. It also will show you that Alvin Beaman, a former member of the city park board, would be proud of his wife's donation of the money to buy this slice of the Highland Rim.

HIGHLAND RIM tablets are safe and non-toxic. They will not promote algae blooms in ponds, and they will not harm fish or other aquatic life. Many waterlilies, such as Victoria (one of the most popular night-blooming lilies), grow poorly with fertilizers containing copper. HIGHLAND RIM'S copper-free formula avoids those problems entirely.

A reconnaissance of the geochemistry of and radioactivity in ground water from the Highland Rim and Central Basin aquifer systems in Hickman and Maury Counties, Tennessee, was conducted in 1989. Water in both aquifer systems typically is of the calcium or calcium magnesium bicarbonate type, but concentrations of calcium, magnesium, sodium, potassium, chloride, and sulfate are greater in water of the Central Basin system; differences in the concentrations are statistically significant. Dissolution of calcite, magnesium-calcite, dolomite, and gypsum are the primary geochemical processes controlling ground-water chemistry in both aquifer systems. Saturation-state calculations using the computer code WATEQF indicated that ground water from the Central Basin system is more saturated with respect to calcite, dolomite, and gypsum than water from the Highland Rim system. Geochemical environments within each aquifer system are somewhat different with respect to dissolution of magnesium-bearing minerals. Water samples from the Highland Rim system had a fairly constant calcium to magnesium molar ratio, implying congruent dissolution of magnesium-bearing minerals, whereas water samples from the Central Basin system had highly variable ratios, implying either incongruent dissolution or heterogeneity in soluble constituents of the aquifer matrix.
