For correlate the water and soil parameter in same study area.
Today, water is one of several sources of fluoride. Fluoride is a mineral that occurs naturally and is released from rocks into the soil, water, and air. Almost all water contains some fluoride. Fluoride can also be added to drinking water supplies as a public health measure for reducing cavities. Decisions about adding fluoride to drinking water are made at the state or local level. Nearly all water contains some fluoride,Fluoride is known to contaminate groundwater reserves globally.Fluoride, which exists naturally in water sources, is derived from fluorine, a common element in the Earth's crust. It is well known that fluoride helps prevent and even reverse the early stages of tooth decay. Natural contamination of groundwater by fluoride causes irrepairable damage to plant and human health. High oral intake of fluoride results in physiological disorders, skeletal and dental fluorosis, thyroxine changes and kidney damage in humans.
Organic matter (%) = Total organic carbon (%) x 1.72
Soil carbon is present in two forms: inorganic and organic. Soil inorganic carbon consists of mineral forms of C, either from weathering of parent material, or from reaction of soil minerals with atmospheric CO2. Carbonate minerals are the dominant form of soil carbon in desert climates. Soil organic carbon is present as soil organic matter. It includes relatively available C as fresh plant remains and relatively inert C in materials derived from plant remains: humus and charcoal.
The carbon cycle is a fundamental part of life on earth. ‘Soil organic carbon’ (SOC) – the amount of carbon stored in the soil is a component of soil organic matter – plant and animal materials in the soil that are in various stages of decay. Soil organic carbon is the basis of soil fertility. It releases nutrients for plant growth, promotes the structure, biological and physical health of soil, and is a buffer against harmful substances. Soil organic carbon, the major component of soil organic matter, is extremely important in all soil processes. Organic material in the soil is essentially derived from residual plant and animal material, synthesised by microbes and decomposed under the influence of temperature, moisture and ambient soil conditions. Organic matter makes up just 2-10% of the soils mass but has a critical role in the physical, chemical and biological function of agricultural soils. Carbon is a measureable component of soil organic matter.
Organic matter contributes to nutrient turnover and cation exchange capacity, soil structure, moisture retention and availability, degradation of pollutants, greenhouse gas emissions and soil buffering.
Total organic carbon (TOC) is the carbon (C) stored in soil organic matter (SOM). Organic carbon (OC) enters the soil through the decomposition of plant and animal residues, root exudates, living and dead microorganisms, and soil biota. SOM is the organic fraction of soil exclusive of nondecomposed plant and animal residues.
Fluorocarbons, sometimes referred to as perfluorocarbons or PFCs, are, strictly speaking, organofluorine compounds with the formula CxFy, i.e. they contain only carbon and fluorine,though the terminology is not strictly followed.] Compounds with the prefix perfluoro- are hydrocarbons, including those with heteroatoms, wherein all C-H bonds have been replaced by C-F bonds Fluorocarbons and their derivatives are useful fluoropolymers, refrigerants, solvents, and anesthetics.

Thanks Prem Sir,
But Over use of fertilizer ( Sulfate base ) in heated area ( Aprox 45-48 Deg.C) and low rain fall can increase the cadmium although its limits is 0.003 but can be found in agree soil.
There is no relation between Fluoride and Organic Carban in Soil. However if any correlation exits , this may be because of Anthropogenic sources of such material which may contain Fluoride as well as organic Carban , which further effecting the soil which may intern harm ful to ground water too.
