Safe Drinking Water Act Latino and African American populations are at higher risk of exposure to drinking water contaminants. Contaminants found in the drinking water of such communities include nitrates, coliform, and lead, which have been linked to cancer, reproductive health problems, gastrointestinal illness, and other health problems. One study found that levels of contaminants in the drinking water of two Nebraska Native American reservations were significantly higher than regional contaminant levels. Another study found that Latino residents in Tucson, Arizona, had higher than average levels of contaminants in their drinking water, which were linked to higher rates of cancer and neurological disorders among
Crop tolerance to seawater are shown in the following table: Halophytes, or salt loving plants, can be irrigated with pure seawater with the aim to grow fodder crops. A trial was made by Glenn et al. to use halophytes for feeding of sheep and it was concluded that the animals thrived well. Setting the yield of an alfalfa (lucerne) fodder crop irrigated with fresh water (2 kg/m) at 100%, the following results were obtained for the yield of halophytic crops irrigated with seawater: After selecting the most salt tolerant strains, the University of California at Davis has grown barley irrigated with pure seawater and
