Human pathogens in these wastes can cause short-term <br />effects, such as diarrhea, cramps, nausea, headaches, or other symptoms. They may pose a <br />greater health risk for infants, young children, the elderly, and people with severely - <br />compromised immune systems. <br />PUBLIC WATER SUPPLY IDENTIFICATION (PWSID): 1020035 PAGE 5 <br />
