This study present the environmental impact of the industrial pig farms and the high pollution degree of the environmental factors (water, air, soil and people). Reprehensible management and carelessness about the potential dangers of the waste and the failure to install decent pollution control equipment and treat the waste resulted in violations of the permitted limits for phosphorus, faecal coliform and other pollutants. One way that pig farms waste pollutes is through the sprayfield system, which is supposedly meant to fertilize crops. But often too much of the untreated liquid manure is sprayed, resulting in crop damage and contaminated soil, groundwater as well as pose a serious health risk to the small segment of the population subject.
