If dogs and cats are crapping in sand pits then there are sure to be
Cryptosporidium oocysts and Giardia cysts present.
Have a look at the following reference.

<One hundred faecal specimens, randomly collected
from various locations within seven public parks in the west
of Scotland, were examined for the presence of Giardia sp.
cysts and Cryptosporidium sp. oocysts. Eleven percent of
samples contained Giardia sp. cysts and 1 % contained
Cryptosporidium sp. oocysts. Occurrence data from individual
parks varied from 0 to 40 % for Giardia and 0 to 2.4 % for
Cryptosporidium. The occurrence of parasitic organisms in
public parks, especially in the vicinity of children's
playing areas is a matter of concern for public health
officials and regulators of leisure and recreation
