Analysis: Public Health Implications Arsenic in drinking water is a world wide environmental public health threat. Anyone who drinks water contaminated with high amounts of arsenic can be effected by it, but developing countries are the ones who seem to suffer the most from arsenic poisoning. The united states and the World Health Organization (WHO) applied a strict standard for arsenic in drinking water to be at or below 0.01 mg/1 or 10 parts per billion, but unfortunately not all countries…

If a city wants to get bigger than it must expand in many ways such as houses, stores,parks,etc. Irrigation is one of the ways that an early city would need to improve on. Yuma was a great land of opportunity because it was in the desert and there was a lot of flat land and a good source of water. So farmers came to Yuma to try and grow there crops. Eventually there were at least 5000 people in Yuma but there were so many farmers it was harder to share and give water to one another.The canals…

Key Design Drivers The following were the key design drivers for the lower and middle completion string: • Desire not rotate SAS completion string if possible, configuration was set-up with the ability to rotate to bottom (swivel system utilized as contingency) but not as primary method of installation. Note: all previous Husky wells have been installed without rotation • Offset well friction data and the as-drilled 216mm open hole friction factors used to provide accurate T&D analysis prior to…

Remediation: The mudboils in Tully Valley are caused by artesian pressure. To reduce mudboil sediment discharges from the mudboil depression area to Onondaga Creek, remedial measures were implemented. This includes installing depressurizing wells along Onondaga Creek and around the mudboil depression area to decrease the artesian pressure. Since the majority of mudboils in Tully Valley are located near the Onondaga Creek mudboil passageway and mudboil tributary diversion channel, the…

Prior to the 1980’s and environmental laws and concerns, it was a standard unwritten procedure to dump waste on the ground, rivers, streams and oceans. Unsuitable boxes, containers and storage units for keeping waste were inadequate and often toxic substances were left out unsecured. These practices were happening destructively everywhere in the environment and thousands of contaminated sites were created. Contaminated sites often included warehouses, landfills, processing plants and…

Yet to date I haven't received any report on the sample I mailed-in? Given the sample size required in your kit is smaller than the sample size required by water testing laboratories. I don't believe High Quality Water of AZ ever intended to have the sample tested for quality. Furthermore, I believe your only using the promise of water…

The year’s themes include: SALTWATER ECOLOGY THE HUMAN BODY ELECTRONICS AND ROBOTICS The children begin the year by studying plants and animals of the Long Island Sound through several field trips to Cove Island Park, where the students become immersed in the various habitats it provides. They work with…

The remedial action objectives (RAO) for the Site presented in the ROD are: · Groundwater: Prevent human ingestion of, inhalation of, or dermal contact with groundwater that contains concentrations of PCE above 5 µg/L, TCE above 5 µg/L, cis-1,2-DCE above 70 µg/L, and trans-1,2-DCE above 100 µg/L (these concentrations are the maximum contaminant level goals (MCLGs) set by the Clean Water Act (or are Maximum Contaminant levels [MCL] where MCLGs are set at zero)). · Soil: Prevent human ingestion of…
