Groundwater Debate Has anything you want or need in your life been cut off from you? Well‚ California is debating on whether or not to pass a law throughout the state that will regulate the groundwater that both residents and farmers are allowed to use over a specific time.

water supply will reach our groundwater. The conclusion that I arrived at was‚ that there are still large remnants of contaminates in the groundwater supply after it has had a chance to be passed through soil. We emulated this affect by using smaller amounts of contaminates such as oil‚ vinegar and laundry detergent. Put them in a smaller amounts of water and then passed them though soil. Introduction In the introduction‚ I will list

Heavy metal contamination occurs though all facets of life such as air‚ water‚ food‚ soil‚ and in everyday objects and occurrences. When heavy metals enter the air from factories emissions and smoke‚ it is exposed to the body‚ which mostly affect your skin and lungs such as Cadmium and Arsenic. Common water contaminates are Chromium and Thallium‚ Chromium can enter the water source usually through spills and leaks from power plants. Thallium like other metals occurs naturally in water but some areas

There are no health effects in ingesting water with chloride although it does give a salty taste that is undesirable. Water that contains chloride should be checked for sodium because sodium can cause health effects. The MCL of total chlorine is 4.0 mg/L and it can cause stomach discomfort along with nose and eye irritation. The EPA Secondary Drinking Water regulation
