Groundwater

Since I live in the Texoma area the majority of our drinking water comes from Lake Texoma. I think the three sources of groundwater contamination that might affect groundwater in my area would be human-made materials that are littered into the lake, agricultural activities, and human/animal wastes. There are a lot of people in the area who like to go fishing near the lake and drinking alcoholic beverages. These people throw their beer cans and all of their trash into the lake. They also urinate and

Geochemistry plays an important role the distribution and mobilization of As in groundwater aquifer. To find the influence of geochemical processes of As mobilization in groundwater of the study area, the correlation matrix among As and various physio-chemical parameter are given in Table 4. Pearson correlation matrices show that various physio-chemical parameters pairs of groundwater samples have a significant positive correlations such as TDS–EC (r = 1.000), TDS–Na (r = 0.587), TDS–Ca (r = 0.624)

The USSL diagram classification of groundwater samples has been shown in figure 8. The samples are classified as C2-S1, C3-S1, and C4-S1 categories. 23 samples (47 percent) were placed in C2-S1 class. The C2-S1 class points to medium saline water and low sodium amount which poses no hazard of sodium exchange for agricultural usage in every type of soils. 45 percent of groundwater samples (22 samples) were in the C3-S1 class, meaning that water is highly saline, sodium is low and there is little hazard

The groundwater of California is a serious policy matter in legislation. If there is drought, such as years like this, then management is necessary because it may encourage more pumping to supplant the water not gathered from other resources. Groundwater can account for as much as 35% of all the water used by California (cite). Unfortunately, there are not many laws established to regulate groundwater. The basins can replenish if they are pumped on a limited basis during normal or peak years. Luckily

need to focus our energies on preserving its quality and quantity. Nitrates pose a great threat to our precious groundwater. There are many ways that groundwater can be contaminated, but most aren't nearly as detrimental as an increase in the amount of nitrates within our groundwater. How do nitrates get into the water? We can help you with this answer. Nitrates get into the groundwater from a variety of sources: some involve pastoral farming, market gardening, application of nitrogenous fertilizers

Period 6 12 April 2017 Main Claim: The state of California must prevent groundwater overuse by regulating groundwater use, making regulation telling farmers when and how to water crops, and improving aquifer water levels with new innovative technologies. California Groundwater Depletion: An Ever Increasing Issue The state of California may run out of groundwater in as little as ten years. California is dependent on groundwater, and without it, it would be thrown into a statewide water crisis. So

Introduction The initial article that I have chosen is an overview of the connection between human health and groundwater. Written by Stephen Foster and Gillian Tyson (2016), the key messages of this article are how many of us rely on groundwater, which makes us more susceptible to pollution, and the effects of pesticides and chemicals. Published by the International Association of Hydrogeologists, this article directly relates to two of the United Nation’s Sustainability Goals, which are Clean

Up to 2014, there had been no coordinated effort on how to manage groundwater throughout California. This widely used water resource had no formal groundwater law or policies governing its use. If anything, the predominant way in which it has been managed has been through water districts that have groundwater management programs and court adjudications. The groundwater rights that exist in the state have been correlative rights, appropriative rights, mutual prescription, and notions of equitable

matter of great importance. Hydrogeologists and water resource managers have realized that the increased demand for drinking water, due to population growth, has placed a huge burden on our nation's groundwater resources. Groundwater resources make up a minute 0.31% of the world's water supply. Groundwater quality can be defined in terms of the concentration of its chemical constituents relative to a variety of potential uses.

Groundwater samples were collected and reported by Sultan et al. (2011) from Sinai for isotopic analyses of H and O from open and productive wells tapping three types of aquifers: (1) fractured basement, (2) Nubian Sandstone unconfined aquifer cropping out at the foothills of the basement outcrops, and (3) alluvial. They believed that the unconfined and alluvial aquifers fed by a fractured basement aquifer through discharging into the overlying sediments. The δD and δ18O isotopic compositions of
