Ground water in the Lajas Valley, Puerto Rico
Henry R. Anderson
1977, Water-Resources Investigations Report 76-68
Lajas Valley is plagued with salinity and waterlogging problems of the soils. Use of brackish (500 milligrams per liter) ground water for irrigation compounded the problem until an irrigation-drainage system was constructed in 1955. Lajas Valley is an alluvium-filled trough between volcanic and limestone highlands. The alluvium, mostly clay and...
