Data in Brief
|April 5, 2021
Summary
Water quality in Setiu Lagoon was monitored across different monsoon periods. Nutrient levels were found to be within Class 2 standards according to Malaysia Marine Water Quality Criteria and Standards.
Area of Science:
- Environmental Science
- Marine Biology
- Water Resource Management
Background:
- Setiu Lagoon's water quality is influenced by monsoon patterns and anthropogenic pressures.
- Understanding water quality is crucial for managing coastal ecosystems.
Purpose of the Study:
- To present water quality data for Setiu Lagoon across different monsoon seasons.
- To assess nutrient levels against established water quality standards.
Main Methods:
- Water samples were collected twice daily (high and low tides) at eight stations.
- Surface water parameters measured: temperature, salinity, chlorophyll-a, and nutrients (ammonia, nitrate, phosphate, silicate).
- Hourly current speed and direction data were collected using current meters.
Main Results:
- Nutrient concentrations in Setiu Lagoon were classified as Class 2 based on Malaysia Marine Water Quality Criteria and Standard (MWQCS).
- Data provides a snapshot of water quality conditions during southwest monsoon, wet northeast monsoon, and dry northeast monsoon periods.
Conclusions:
- The collected dataset offers insights into Setiu Lagoon's water quality dynamics.
- Findings are valuable for understanding the impact of human activities on lagoon water quality.

In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
