Zambezi floodplain, Zambia

Misria

Lozi people living on the vast Zambezi (Barotse/Bulozi) floodplain in Western Province, Zambia, are experienced agriculturalists long adapted to seasonal patterns of flooding and drought. Compounded histories of colonialism, administrative disenfranchisement and neglect, extractive activities, and the concomitant reduction of territory and authority have impoverished the regional ecology and people. Increased climatic variability and other ecological challenges threaten Lozi ways of life, crops, and biodiversity more generally. Fish stock depletion is a major challenge reportedly partially caused by chemical contamination from insecticide treated mosquito nets used for fishing, other poison-based fishing methods, and from a Canadian mining company’s activities there. A Chinese construction company that built the bridge spanning the floodplain reportedly cultivated shrimp and snail species that threaten native fish populations. While seasonal fish bans are in place, their timing does not always correspond with traditional bans, and increased hunger (along with the impossibility of enforcement) renders such bans ineffective. In addition, some fish species have disappeared altogether. Biodiversity losses, which include water serpents deemed to be responsible for maintaining the structural integrity of the river, impact biopolitical life, cultural heritage and TEK. Appeals to UNESCO for Heritage status and WWF projects are underway and may confer some protection, however local suspicion remains due to prior agreement violations (with other bodies).

The article informs its readers that there is an excess amount of lead in Newark's drinking water as of September 20, 2017. Five addresses had the tap water tested and the lead levels exceeded at least three times the federal standard and Newark's Water Department was informed. The article then explains the process at which Newark's Water Department must go through in response to the excess amount of lead and what residents must do.

The U.S. Environmental Protection Agency’s Lead and Copper Rule regulates the presence of lead in drinking water. Under the rule, if more than 10 percent of samples test above 15 parts per billion, the federal lead “action level” is exceeded. An “action level” exceedance triggers mandatory requirements that a water system must perform. For Newark, these requirements include water quality monitoring, corrosion control treatment, source water monitoring and treatment, public education, and lead service line replacement. Newark must treat its water to guard against corrosion (pipe erosion and damage) to minimize lead “leaching” (when lead is dissolved from pipes or fixtures and transfers into the water) or flaking of small lead particles from pipes or fixtures into tap water.

This article brings Newark’s water contamination problem up, specifically the amount of lead found in recent studies. Newark’s water was found to have three times the amount of acceptable lead in its tap water, but no specific locations were give as to what places are being affected by this contamination. Newarks Water Department will be required to take actions such as testing public school water supplies, changing lead pipe lines, and maintaining more accurate maintainence schedules and records. By holding people accountable, Newark is changing its vulnerability towards water contamination
