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.

Grimason,AM; Smith,HV; Parker,JFW; Jackson,MH; Smith,PG; 
Girdwood,RWA (1993): Occurrence of giardia sp cysts and 
cryptosporidium sp oocysts in feces from public parks in the 
west of scotland. Epidemiol. Infect. 110(3, Jun), 641-645.
       (Stobhill Gen Hosp, Scottish Parasite Diagnost Lab, 
Glasgow G21 3Uw, Scotland . Stobhill Gen Hosp, Scottish 
Parasite Diagnost Lab, Glasgow G21 3Uw, Scotland. Univ 
Strathclyde, Div Environm Hlth, Glasgow G4 0Ng, Scotland)
       <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 
amenities.>

Hope this helps,
