give brief detailsabout these stages in water sanitation: capture, storage, transport, treatment and disposal or reuse of human excreta and wastewater.

Leachate production is what

Summarize the stages in sewage and wastewater treatment.

Scenario 1 HPA = 32 MMhG, HPV = 15 mmHg, HPISF = 0 mmHg, OPISF=0mmHg, OPCAP= 25mmHg, NFP= net filtration presssure, NFPA= 7mmHg, NFPV= -10mmHg Scenario 2 HPA= 38 mmHg, HPV= 15 mmHg, HPISF=2mmHg, OPISF=1 mmHg,      OPCAP= 17mmHg, NFP= net filtration pressure, NFPA= 20mmHg, NFPV=-3mmHg Question: what could cause the HPA and OPCAP to be so different in scenario 2 compared to scenario 1.

Coliforms are commonly used as an indicator of drinking water quality. As we discussed, in March and April of 1993 there was a major outbreak of gastrointestinal illness in Milwaukee, Wisconsin caused by contamination in the public drinking water supply.  As summarized by MacKenzie et al.1, “throughout the period from February to April 1993, samples of treated water from both (water treatment) plants were negative for coliforms and were within the limits set by the Wisconsin Department of Natural Resources for water quality.”  Why, in this case, did coliforms remain at acceptable levels despite water contamination that resulted in over 400,000 cases of gastrointestinal illness?
