Answer:
Nitrate levels in the water are higher than permitted.
Explanation:
Groundwater supplies drinking water in eastern Washington's Columbia Basin. Approximately 20% of all monitored wells in Adams, Franklin, and Grant Counties had nitrate concentrations above the US Environmental Protection Agency's nitrate contamination threshold. After getting approval from the Washington State Department of Ecology, the Columbia Basin Ground Water Management Area was set up in February 1998. At first, the main goal was to lower the amount of nitrate in the ground water.
Answer:
The Atlantic slave trade had a negative impact on African societies and the long-term impoverishment of West Africa. For some it intensified effects already present among its rulers and kingdoms.
Explanation:
The use of African slave labour was not new. The Spanish and Portuguese had been using African slaves since the 16th century. However, the Atlantic slave trade of the 18th century was a new kind of slavery and was on a scale much greater than ever before.
The implications of the slave trade included:
Effects of the trade on African societies in West Africa
The slave sellers and European ‘factories’ on the West African coast
The development of slave-based states and economies
The destruction of societies
The development of foreign colonies
Leaders of African societies took roles in continuing the trade
