I checked your paper but did not find any mention on the observation well.

Q1: Where and at what distance is this well located in relation to the location of the latrine-cum-digester site. ?
Q2: how deep is the water level of the well ?

The water quality of this observation well looks very impressive.

Q3: what do you attribute this high water quality to, i.e.
- is it because of slurry is contained in the digester and compost pits ?
- do you think that the used of compost will disperse any parasitic ova and cysts ?

My questions as given above, were not answered:
could you provide a detail list of pathogens being studied in your test
Q4: what were the coliform and ova/cysts counts, if these were analysed for
- the influent for the digester
- effluent of the digester
- in the compost pit after 3 months.

In your paper, you wrote:

did you take samples for analysis from the garden soil and for whatever were grown in the watchman's garden ?
